New MicroSD Card Question

Hey guy's I recently purchased a 8 GB MicroSD card and I got it in the mail today, so before putting it in my phone I put it on my computer and it doesn't read 8 GB it reads 7.59 GB. Why is this?

Capactities will never be exact. That is true of flash drives, hard drives etc. My iPod is theoretically 80GB but is actually only 76. Annoying...but that's just how it is

http://www.technical-assistance.co.uk/kb/hddsize.php
same thing really it's been the case for eons

sd cards
well they are true about how they always vary in capacity for posted size but for hardrives it usually actually is withing a couple percent, where as flash being very unstable memory can come with no memory lol, but also some of the memory is take up by foratting the device to work with operating systems and able to hold files and everything

That's because drive manufacturers measure like this:
1MB = 1000KB
1GB = 1000MB
And operating systems measure like this (the correct way):
1MB = 1024KB
1GB = 1024MB
So the card you bought has 8,000,000KB. The manufacturer claims that's 8GB. Windows sees it as...
8,000,000KB / 1024KB per MB /1024MB per GB = 7.629GB
Then a little bit of space is used for formatting, which leaves us with 7.59GB.

yeap!!

Must of user needs to know how sizes arent exacts! just think about why it arent memoryes for 200MB over 256 or 32 not 30MB

740 or 512MB ROM?

Can someone who actually HAS the phone verify this for me?
Over here it says 740
http://www.androidcentral.com/droid-incredible-vs-evo-4g-vs-nexus-one
AC claims to have gotten this info direct from HTC
http://www.androidcentral.com/about-rom-storage-droid-incredible
Verizon website says 512, and a couple others say 512 as well.
So what's going on here?

I can tell you what mine says:
Internal Phone Storage: 6.60 GB
Phone memory: 748 MB
HTH

Same here... my best guess is after the 512mb of RAM and 512mb of ROM this is what's left over for the user?

I have :
Internal Phone Storage: 6.60 GB
Phone memory: 748 MB

I have 748 Total, and 685 of that available.
Even 512 would have been plenty.

Interesting.. I wonder why they wouldn't capitalize on that by at least showing it on the main website or verizon..
http://www.htc.com/us/products/droid-incredible-verizon?view=1-1&sort=0#tech-specs
If it were true, i don't get it. Having 748 over 512 is a huge deal.
When I see 512 I cry a little inside wondering if it's gonna run out of app space
It's possibly a miscalculation or error in the software. Maybe it should be 512 after all, since both the verizon and HTC pages for the phone have no indication of any more than 512MB of ROM..
Also I hear we're not able to install apps to the 8GB onboard, sans root.
What will change with the arrival of Froyo?
Will we be able to send apps to the 8gb as well as the sdcard?
That would put me at ease..
EDIT: God HTC has done a really crappy job with reporting specs on this phone!!
http://shopamerica.htc.com/cell-phones/productdetail.htm?prId=37106
Over here it says the incredible has a 2.5mm headphone jack while on the tech spec page above (still on HTCs website) it says 3.5 (which I know to be true)
This, and the ROM crap is making me consider another phone, as this one appears to have been poorly executed.

I don't think this is a big deal...

Considering that EVERY android up to this point has not been able to do this without root, it is kind of a mute point. Froyo is supposed to change that, but it hasn't made that much of a deal up until now.
No other Android device that I know of has Internal 8gb storage either, not even the EVO...

I don't mean it as a point against the phone.
Simply noting that theres 8gb memory that COULD be used for app storage.
So i hope with froyo they implement a nice way to send apps to the 8gb memory OR the sdcard. Rather than only the sdcard.
The 8GB onboard is great, and knowing that i can have upto 40GB space available on my phone is pretty wonderful.
I just want to be sure that I can use every bit the way I want.
I had the G1 and root was more of a necessity than "extra benefit".
So I just hope the incredible doesn't need third party intervention to be the phone we all want it to be.
I don't think thats too much asked.
On my g1 I had about 400+ apps, and I KNOW that if I only have the 512 rom for app storage I'll be running out at one point or another..

Regardless of 512 or 748 I wouldn't worry about running out of app space. I don't know of anyone who has. Even on the smaller droid I didn't know anyone who.did.

[Q] Memory Shortage

I don't know if anyone else has noticed this but on the internal memory of my E4T it only has 12GB of available space instead of the advertised 16GB. 4GB may not sound like much but I could really use the space and am trying to hold off on buying a microSD card.
If anyone can help with a solution or give me an answer on why this is it would be greatly appreciated.
Thanks!

I believe it's a norm to falsely advertise storage space in GB now. Our 16Gb is actually 16000mb, which equals to 15.625gb.
2 of that is partitioned as System Memory. If I am not mistaken, the OS takes up the balance.

Bingo. They advertise the unformatted capacity.
And its not just Samsung... Take any flash drive or SD card, or even hard drive, and compare the ACTUAL free space with the advertised capacity. It will always be lower, sometimes significantly.

[Q] Storage space?

I got my (allegedly) 16GB Note 2 on Saturday and installed loads of stuff, including some pretty big Gameloft games. When I go into Storage from the Settings it says that my device memory has total space of 10.36GB with 2.98GB of it left. The fact that 7.38Gb is used up is probably about right given all the large games I've got on there, but why is the total space only reporting as 10.36GB when it's a 16GB model I bought? I'd expect some space to be used up by the OS itself and the various protected system partitions that come with it obviously, but does Jellybean really consume the GBs of space that make the difference between the 10.36GB reported and the 16GB that should be on there?
I used a disk info app to see what was going on and have attached a screenshot of it's output. I'm not sure what the difference is between the Data and SD card partitions there. Note that I do have a proper external SD card in the phone but it's only 2GB and so isn't any of those partitions. Anyone know what I'm seeing here and where my 16GB has gone?

Yes, this is the available amount of of space you get in this phone.
Its not just this phone! Any phone you get from market will have less user-available storage.
One X is said to be 32 gb but you can use only 25 gb
Here is a mod whoch can increase your space to around a bit above 11 gb http://forum.xda-developers.com/showthread.php?t=1931500
Any 16 gb phone made has around this much user available space rest is OS and other stuff.
HINT: buy a 32 gb memory card? it will replace your internal memory card need exactl as if it was internal memory storage.
How? You can transfer all apps to SD Card using titanium backup so your phone memory and SD card memory is basically unified.

Partitions of the SGS III (I assume pretty much the same in Note II):
/system: 1G
/data: 11G (shared with /sdcard)
/cache: 1G
Add to this space required by OS and installed apps.

The 'Advertised vs actual' factor as described in that article would take just over 1GB away from a 16GB start (70.3 MB x 16 = 1.12GB).
Adding in the Cache, System and Data/SD Card values from my screenshot would take us up to 13-and-a-bit GB. (1.12 GB + 1GB + 1GB + 10GB = 13.12GB)
The System partition hold the OS and any other baked in stuff (as I understand it) so where's the other 2-and-a-bit GB?
I'm sure it's all explainable so I'm just curious to know how this works. I thought I remembered having more free space on my previous Note and the GSII before it (both of which were advertised as 16GB) but perhaps I'm misremembering.

It would be interesting to get a clear answer for sure... I have a 64GB SDXC with 30GB free space on it and I can't think of anything else I would need that isn't already on there, I couldn't fill it up even if I tried. Also I still have 8GB free on my internal...
I don't listen to music on my phone, I have a dedicated player for that, so that's why I don't need tons of space... and that's why I don't really reflect on these things, but am a bit curious indeed about why the available space is so much less than 16GB.

My usage is pretty much the same as yours (external SD card with a few things on it and separate dedicated mp3 player) so it's not something I'd usually notice either. The only reason I've clocked it this time is because I bought a few GB and bigger sized games in the recent 25p Google Play store all of which I've installed as soon as I set the phone up on Saturday; whereas usually I'd install one 'proper' game and only install a new one when I'd finished the last one. So, as such, this is probably about as full as my phone will ever be and not something that'll cause any problems, but it would be good to understand what's going on here.

[Q] Galaxy S3 RAM Memory

I have the Galaxy S3 SGH-L710 (Virgin Mobile)
I used the CPU-Z app to view the hardware info.
CPU-Z reported that my Ram memory is 1.57 GB (1579 MB)
This model phone is suppose to have 2 GB of memory.
Just wandering if it's an indication of bad memory, or a software glitch or if it's something else.
Can anyone with same model post here and let me know what you get.
See if you have same reading as me. Thanks.

I believe some RAM is allocated to system files on boot so that the phone can start up. Also, the amount of physical space on a chip is different than the space a system can use. For instance any flash drive you get that is advertised as having 16 GB of space, actually has about ~14-15 GB, because they say that it has 1.6 billion bytes (or whatever the number is), but there are 1024 kb in 1 MB, and 1024 MB in 1 GB, plus the space needed for driver files lowers the total amount of space available to what you see. So all of that is probably what amounts to what you're seeing, I'm not an expert nor am I a developer, but I've looked into these things a bit.
Plus, you could just google search "why is my phone's ram less than it's supposed to be" and get a clearer answer!

Thanks for your response. That explains things.
