SD Card Speed Postings! Participation wanted!

ok I see a lot of quadrant scores and stuff here .. which is great and all .. but I would like to see what everyone is using as far as their sd card goes. This will help others who see this choose an sd card that is proven to be effective here .. a reliable source to say.
I would like:
1) Brand, Size of card, and Class rating
2) Price and where it was purchased at
3) what you think of the card
4) a screen shot of the speeds .. I used SD Tools (free and it lets you save a screenshot)
so here is mine:
1)OEM systems 32GB class 10
2) $57.25 on amazon http://www.amazon.com/OEM-microSD-m...4AJO/ref=sr_1_2?ie=UTF8&qid=1320822033&sr=8-2
3) I really havent decided if I like this card or not .. when I run the benchmarks in my class 10 8gb card from sandisk the speeds are much better (15mb write to 8mb write now). I dont know if I can tell a difference in the performance of the phone ... maybe a little loading pictures in my album... but I also have my Nikon DSLR 7000 full size photos on there as well .. so its to be expected i guess.

Have a Patriot 32gb class 4 and via sd tools I'm getting write = 5.1 MB/s, read = 15.6 MB/s. Not sure if this is good or bad given the class 4 rating compared to others.
With a little speed tweak in place;

if the write speed is ABOVE the class number, then it means you got a good card
in your case it was rated Class 4, so it supposed to guarantee a minimum of 4 MB/s write to the SD card
and your score shows 5 MB/s that means it's good, and not a fake counterfeit or defective unit, which might have shown 2 MB/s
even on the oldest of my phones like the Treo650 it was able to easily write above Class 6 speeds

Thanks, I know there's somewhat faster cards out there but seems fine for my intended uses such as photos, music, videos, etc. Is there any merit to the SD speed tweak apps I've seen on the market?

Lol wow ... I'm using the mobile app and I thought my thread got deleted .. But just saw it on the sticky side!
Allgamer ... Lol wow nice contribution there!
Thanks to the others for the replies a well!
Oh and if a card has been put here already ... Still post yours. A result is good but multiples shows consistency... Or lack of.

i've been using them for many years already, so they are safe
they offer life time warranty, however it takes a bit of work for them to replace your dead cards

Patriot 32Gb Class 10
Originally bought this card maybe one week after it was released, approx one year ago. Bought it on Amazon for approx $105. Recently totally crashed and could NOT be formatted. I did have off and on weird issues with SD card not recognized, and basically had to reformat. Was running the card in Nexus one, as well as the Sensation 4G. Patriot did an RMA on the card and the replacement runs twice as fast as the original. I think my first card had some weird bugs. Glad it died off. Patriot did honor their unconditional 5 year warranty BTW. I typically get 10MB/s write speed when copying ROMs over from my PC over USB. I used to get only 3Mb's at best with the original card. Using BeastMod II v2.1 ROM.
Edit:
http://forum.xda-developers.com/showthread.php?t=1010807 go to this thread and it describes how changing the cache settings can alter read speeds. I seem to get better results using 4096 setting, while I used to use 1024 setting on my Nexus one. Best to test settings for yourself. My read speeds increased to a consistent 21.0MB/s. Write speeds were anywhere from 9.0 to 10. The cache settings only affect the read speeds, BTW as far as I know.

TopRam from Amazon
16GB Class 10 for $24.99, and it comes with a reader. I have been using it for 2 weeks with no issues. Unfortunately, since I'm new here, I cannot post a link to it. But search for TOPRAM 16 on Amazon and you will get lots of hits… This one was from Midwest Memory Outlet... the one with the red reader
Here are some test pix

yes, the cache only works for read, and it doesn't improve it by much on fast phone like ours, is good for older phones that were Sub 1 Ghz
as for your writing speed, it did not even reach the minimum guaranteed of 10 MB/s
you are only getting 9 MB/s write on both test
Yet another reason why i do not trust that brand Patriot

how about sharing a screenshot of the test?

[Review] Samsung 64GB Pro UHS-1 card

I got myself a Samsung 64GB Pro UHS-1 card directly from Korea. It's one of the newer 20nm cards rated at 20mB/s write and 70mB/s read speeds.
I got it from this seller on eBay for $91. I got it within a week from ordering it, which is quite good considering I'm on the other side of the world.
Compared to the SanDisk 64GB UHS-1 card, on the phone itself I'm getting:
With SD Card Tester app:
SanDisk: 9.25mB/s write, 12.95mB/s read
Samsung: 13.71mB/s write, 12.78mB/s read
Edit: I increased the readahead to 1024K and I'm getting 18mB/s read on the Samsung.
The SanDisk card shows up as 59.47GB, the Samsung one as 58.53GB on the phone.
Seems disappointing considering the advertised speeds. However this is caused by the host controller on the phone seemingly limited to 100mbit/s on both cards, so for people who want to expect a big boost here, don't. I guess we won't see better scores until Exynos 5 devices come out.
Tested on my laptop reader with an adapter:

}
It looks like the reader itself is the bottleneck here too, however the SanDisk card is clearly outmatched by almost a factor of two by the Samsung card, especially in the write tests.

Speeds may be twice as much but so is Samsungs price. I got my Sandisk for $46. I think I can wait for the Samsung price to come down.

Yes and is the Note 2 or any other available device really in need of that extra speed? I doubt it does. When the price comes down then it will be a good buy for phones.

no phone supports uhs 1, so you won't get the advertised speed.
try to get a uhs 1 reader and try again.

I don't know what the hardware differentiation is between normal and UHS speed modes, but the host device driver in the phone does support and uses UHS.

looking at you results, you card reader does not support uhs 1, otherwise you will get 70/20 or more as stated.

That's an up to advertisement, it doesn't guarantee anything. It also doesn't explain why the Samsung one is twice as fast as my SanDisk, because they would be both be limited at the same speed of the host controller if that's the main cause.
The host controller driver in the phone runs at SDHCI spec v2 while v3 is the new version, however the speed is determined by the host controller bus width and speeds and are independent of the spec beyond the minimum requirements. The SDHCI on this SoC is also the HSMMC which controls the internal memory and that one is capable of 62-65mB/s read speeds. If anything, the USB 2.0 bandwidth limit is more of a problem.

it's upto you to use compatible and supported hardware, it doesn't matter if you pc has the supported driver, do you have a uhs 1 card reader, if not , the speed is not reachable.
for the sandisk ultra it state upto 30, i have a 32 and 64, both reach 38mb/s.
you cannot test full speed on the phone, it a card reader to pc that you need, as i said, no phone supports uhs 1.
if you want faster card, and you do need a uhs 1 card reader, try the sandisk extreme pro at 95mb/s.

I'm talking about the phone's host controller and that's the spec it is running at extracted from the hardware, and on that the Samsung is still faster, it's an apples to apples comparison regardless if the top speeds are limited or not.
Those extreme pro's are nice, but come only in maximum of 16GB and are outlandishly unavailable or expensive, they're the same price as the 64GB ones.

thats why i'm waiting to see if a ep 64 will arrive, as stated, no phone will allow you to reach near the stated speed, unless one i made to support uhs 1 or the new uhs 2 which isn't released yet..

If so then why buy the expensive SD cards to put on the phones that not yet have the needed support in order to have the max. speeds?
In fact you put the card into the fone most of the time, not to the reader into the PC - so the card's speed when plugged into the fone is the thing that is most important, not the speed when you test in ur PC.
=> Wait until the prices of the new SD drop & the new support for them come out for the fones

I have just got myself a Transcend microSDHC Ultimate 32GB to try out; have been using the SD Ultra 16GB (both Class-10)
The seller has both cards for the same money but he points out the TS as he told the speed was more stable when copying big files (like HD Movies).
Have checked the serial in: http://vn.transcend-info.com/Support/SerialCheck_tw.asp?Func1No=3&Func2No=207
Initial impression, not tested yet.
- Sandisk: the outer box and also the card itself to me was better, also the adapter was printed with characters, numbers and Made in Taiwan; the box of the Trans printed Made in TW; while in the microSD itself: Made in Korea; the adapter was not printed with anything.
The performance and stability is to be tested when I get back home The SD has served me well for like a year.
This is how the SD Ultra looks:

Of all the card trandscend, adata and sandisk tend to be the most reliable and stable cards available, whiles toshiba and kingston has the speed, but the speed do fluctuate alot.
sandisk cards are made by themselves, whiles transcend are usually rebadged from sandisk and other manufacture.
adata also has cards made from sandisk and themselves.

kingston is really really bad, stay away from it. SanDisk might be slower but it is solid and yes Transent is very very good, stable and fast.

Transcend Class 10 MicroSD (not the UHS I version)
Quite impressive

thanks for the review! but just an fyi for anyone out there thats thinking of buying a samsung card. average at the time of this post is that the cards are for 90 online. I found on another thread that someone bought the card off frys.com for 70. its the us brand model too

Here's the SanDisk card as measured on my MacBook Air (mid-2012), the card reader is PCIe based so there shouldn't be any bottlenecks.
Instinctively I'm thinking I have a bad card because I reckon it should go faster than this. But meh, I'm pretty happy with those results.

Could you do the retest with S4 (as I understood you've got it?)

Recommend me a good 32Gb sdcard

hi all...
exuse me if my english is bad.
Im planning to buy Samsung S2 I9100note 3 and i want to store heavy 3d games(like N.O.V.A 3,GTA san andreas,Asphalt 8...etc)but the internal storage isn't enough for me,so im gonna buying 32Gb sdcard to move the games data with [Directory bind]app,i know the sdcard r/w speed is slower than internal storage so it might effect the performance of gaming(i guess),so which SDCARD should i buy?and does the sdcard r/w speed matters for gaming(while playing games on sdcard not the internal storage)???
Note:im not gonna buy it online cuz i don't own credit card .
Im just hoping not breaking the forum rules.

Class 10 Speeds up to 80MB/s Reads and 50MB/s Writes
WTF Perforance Range: *(Max capacity is only 16GB) **(Quite sure you won't get these speeds on the SII or any other android device)
Class 10 Speeds up to 95MB/s
The Mid Range card should be more than enough...

720p mode Normal – 9 Mbit Fine – 13 Mbit Super fine – 17 Mbit
Both modes have audio at 48000 khz at 192 kbit

Also for those, who are interessted, my site will be soon updated for an Android section.
www.hx-custom-roms.com
As you see here the 1080p recording at superfine mode require 30MB/s so does that means I have to buy the class 10 with 30MB/s speed to prevent issues?and what is the price of the sdcard class 10 30MB/s at your local shop?

Adding some:
SDSDQU-064G-U46A - should be or should have been the monster but most pre March 2013 can become corrupted or defective as XC are exFat and SII (if not on CM rom) is using FAT32 and you should reformat it to FAT32 (do not use WIndows system format!!!).
Personal story on that one in a very short manner: It just died on me 2 days ago after being used from the September 2012... I have no remedy for it, it's simply dead. I'm in the middle of a dispute with Amazon and from Monday with SanDisk too so to get reimbursed if they're not able to guarantee the subst. card will be from a new batch and with an upgraded ROM chip!
Said that, I have an old class 4 (I think, but unsure as it's from my wife's old Nokia XM5800) 4GB Nokia card mounted now and 720P videos are registering without a stutter, I haven't tried 1080P.
Screens: On the left is a SanDisk Ultra Mobile SDXC class 10 UHS1 64GB and on the right is a crappy Nokia class 4 4GB 2008 card, notice the (not) "great" difference??? Last screen is showing my current layout of the distributed memory on my SGS2. Remark: No apps/games are moved to any other memory but everything is installed on main and I have a total of 254 installed apps and 76 of preinstalled phone apps - as reported by Clean Master. That include 3 SatNav apps with respective maps.

So, at the end of the day: Even many new cards are classified as ultra giga fast you won't be able to see that speed on SGS2.
Advice: Go only for genuine products of a well known brands and retailers you can really make sense of your warranty if it breaks. I guess Pro class HC of 32GB would suffice and choice is vast. Samsung is selling 32GB Plus series at around 22-25 EUR in Europe. I just ordered a Samsung MB-MGBGB/EU Pro 32GB class 10 UHS-1 for 34 EUR so I have recording capacity for the New Year's Eve and night, until I solve the issue with SanDisk and get substitution or reimbursement.
Cheers.

Be sure it starts with SDSDQUA (see that A there, it's important) if you're onto SDXC 64GB version of SanDisk, otherwise you're risking (like most of us did). These are exFAT preformated so bear that in mind. On the other hand if you're getting the 32GB ver (same product code start like I indicated for the bigger one), they're all SDHC, FAT32 preformated, so you should be fine.
See here: http://www.sandisk.com/products/memory-cards/microsd/ultra-class10-for-android/
If not... opt for something else. I'm satisfied (for now) with Samsung 32GB Pro card I took to replace a dead Sandisk 64GB. It tested at 15,10MB/s write and 18,89MB/s read speed on the phone.

Exfat is not compatible on most Rom/kernels I know that stock Roms can read it. If you are using a AOSP based Rom you might need DorimqnX kernel

[Q] Micro-SD speed capability

Tried searching, but coming up empty. Maybe I should have put this in the accessories section.
I need to buy a new micro-sd for my G3 I just got yesterday. I would love to pop for the 128gig Sandisk, but 120 bucks would allow me to buy five 64 gig cards. The only card I have right now is an older 8gig card coming out of my HTC Evo LTE so I definitely want something new and bigger.
Is the G3 physically capable of taking advantage of the cards with the 90 mpbs read/write rates of the higher end cards like the Samsung Pro series? Or would I not see any advantage over the slower 45 mbps cards like the Evo series? I know either card would work, but if the LG G3 is only capable of read/write speeds of 20-30 mbps, the faster card doesnt seem to be worth the money. I think I saw one test where somebody was getting around 19mbps of read/write speeds with one of the Sandisk cards capable of 90 mbps, so this tells me its not worth it to get a faster card for double the money.
This will store pictures and music and the occasional video so nothing crazy as far as use.
64 gig Evo series is 25 bucks, 64 gig Pro series is 50 bucks. The money doesnt matter to me, but if I cant use the capabilities its a wasted 25 bucks.

No, the G3 won't be able to take advantage of the UHS-I speeds. You'd have to remove the card from the phone and use a compatible USB3.0 card reader to see those 90MB/s speeds.

I bought a microsd 128gb for $18..i copied over 1000 songs to my phone in less than 30m

This is from AnandTech, if it helps. . .

Are those graphs showing the built in memory speeds or a Micro SD card speeds?
So basically it looks like it wont be able to take advantage of the ultra fast 90 mbps cards so I should just save my money and get the mid level 45 mbps card. Done deal.

Yes that is showing the internal memory and not the micro sd. Get the cheaper version. If taking 4k record it to internal then transfer to external

It's showing internal, which may be slower than the Samsung Pro cards. I thought the G3 was UHS-1 capable Also, I'd like to know how that guy tested it. If he started loading some mkv videos than OF COURSE it was slower than advertised. Storage always is slower than advertised speeds at transferring compressed media.
On another note, it's MBps/MBPS which is very different than mbps op

he is right. it is fake. I already maxed it out. 8gb total. these fake 128gb microsd are hacked to show 128gb but they are really 8gb. just left him a neg feedback. oh well lesson learned and now time to shop for another 128gb microsd..again. this time I will go to bestbuy.

I have a 64mb Samsung pro card. measures 72MB/sec write and 79MB/sec read in the side of my HP laptop. manages 20MB/sec write and 77MB/sec read in my phone. Internal memory definitely has the edge with 56MB/sec write and 221MB/sec read. using A1 Sd Bench.

I picked up the Samsung Evo 64gig card today at Best Buy for 30 bucks. Working like a champ.
SD Card Tester wont run for some reason.
A1 SD Bench says 42.48 read and 17.38 write which is in line with what this card should do.

The lowest a 128GB microSD has ever been is $99 a while back, regular retail is around $130. As of now, SanDisk is the only legit manufacturer. Never buy such stuff from eBay, and definitely not at such a low suspicious price of $18.
Sorry you got burned.

I'm happy to spend more if G3 can works fine and take advantage with the UHS-I at 30/95.
Is this is to confirm that the LG G3 is able to take advantage of the Micro-SD UHS-I speeds. W:30/R:95-Mbps............right?
Please advise, If I store a lot of Hi-Res images [3-5Mb/image] and some HD video files. Is it worth to go for UHS-I 30/95 or 30/30 is enough?
I'm thinking of
1. Toshiba EXCERIA 32G/Class-10/UHS-I @ 30/95Mbps. @ US $31.29
2. Toshiba 64G/Class-10/UHS-I @ 30/30Mbps @ US $32.59
Thnaks :")

I would say so. just performed a test copy of approx 267MB and below are some screenshots showing speeds.
first is Samsung pro 64MB to internal, second is internal to Samsung pro. it was peaking at over 30MB/sec to the SD card when copying photos earlier.

I wouldn't go for the 128GB just yet. The write and read speeds on them are horrendous!! I got a 64GB with 80 write and its fast as hell!
Sent from my LG-D850 using XDA Premium 4 mobile app

I found that increasing the SD card cache using the "Kernel Tuner **root**" app increases performance. setting to 4096 seems a good level. very slight change between there 6144, though no improvement setting it higher than 6144 in my testing.
SD card manages 33MB/sec write and 78MB/sec read.
internal improves to 70 write and 263 read too.
I noticed that ram tests were faster today. not sure if related to more free RAM, will test again later.

Maximum Micro SD Card worth buying?

I believe that all micro sd speed classes work with the HTC 10:
UHS-I U1, UHS-I U3 and UHS-II U3 (the fastest available).
But the whats the maximum speed this Snapdragon 801 SOC allows? What´s the maximum speed supported, when the SOC reaches it´s top speed?
Could someone with any of these these cards please perform a speed read and write test so we can see if it´s worth buying the fastest available or not?
Cheers

HTC 10 uses a snapdragon 820, not 801.
I believe the maximum card it will take is 2TB.

Correct, 820 SOC, sorry.
My question was regarding the speed and not storage size. I just confirmed that the snapdragon 820 it's compatible with the UHS-II cards (they have a second row of pins) but only work at UHS-I speeds.
Cheers

Oh sorry, I guess I should slow down to read. Yeah I never really knew what speed was supported, I just use a Samsung Evo UHS 2

If you have a look at the XDA review of the 10 you'll see it has one of the fastest sd slots on the market, I confirmed this by using a1 sd bench testing my 128gb Sandisk Extreme which gave me 86.60mb/s read and 57.47mb/s write, essentially maxing out the card, whilst internal memory gave me 226.41mb/s read and 35mb/s write (likely due to encryption). Copying from internal to micro sd copied at a consistent 55-60mb/s as well which is top for a phone.
Really impressed overall, I had a whole heap of issues with slow NAND on my one x and to a much lesser extent m8 (slow sd slot), but the 10 provides a great experience in these areas. So in short, go for the fastest card you can afford, the 10 will be able to take advantage of the extra speed, I personally went through quite a few cards and recommend the 128gb Sandisk Extreme for $60 AUD (60/90) or 128gb Toshiba u3 (30/80) for $40 AUD, otherwise the Samsung cards are pretty bullet proof but 4k video might stutter on the Evo cards and below due to slow write (20-25mb/s tops).

Thanks for your answer. I just ordered the Samsung Evo PLUS UHS-I U3 64Gb since it has faster random write speeds than the PRO, even costing less. Sequential speed is slower, though. http://www.jeffgeerling.com/blogs/jeff-geerling/raspberry-pi-microsd-card which is important if you want to format it has adoptable storage.
So you have a UHS-I U3 Speed Class card, correct?
But you do know that UHS-II U3 cards do not work faster than at UHS-I speeds, right? It's important that people know the extra row of pins which enables it to work at 150mbs and more does not currently work with any smartphone on the market. I say this because they are very expensive and you can only take advantage of that speed when using it with an adapter connected to a PC. So buying it is kind of wasting money since they are much more expensive.
Cheers

So you ended up getting the 10 Badelhas? Hope you're enjoying the phone if you did.
Yep, I'm using a U3 (30mb/s min write), UHS-I card, it does NOT have the extra pins that enable faster performance that UHS-II cards have. You're right, UHS-II cards are far too expensive anyway and the 10 doesn't support them. Honestly wouldn't recommend using adoptable storage, it'll really slow the phone down since the performance becomes bound by the slower memory (the card), even with my Extreme card, performance was noticeably worse, at least in my experience. Pretty much the only benefit of using adoptable storage is for installing games/apps, but if you need it, I can't stop you (as much as I would like to).

No, I still haven't bought the 10, still debating. I have an old class 10 32gb micro sd card on my HTC one m8 and since I ordered a new Samsung 850 EVO 250gb SSD for my pc I thought "what the heck, I'm ordering a new, bigger and faster micro sd card". Impulse buying, I know ? But it only cost 18 euros.
I hope that my HTC One M8 is able to take advantage of the faster speed of the card but that user's post made me think I probably won't

I've just realized that the samsung evo+ I ordered is a UHS-I U1 card and not a U3 speed class so I just canceled my order.
