intel 330 120gb ssd
 

hey guys, setting up a new system for my wife, and I'm planning on using my old 120gb intel 330 ssd. but whenever I try to do a fresh install of windows it says 111gb instead of 120. and yes it's formatted. not sure what I did in the past, can anyone help me out??? and my current ssd which I'm using now a 520 240gb ssd x2 and it gives me exactly the same storage size except some space which had my windows and other stuff. compared to this one which has 9gb missing at the start.

Hard drive manufacturers tell you that 1000 bytes = 1 kilobyte and does not use binary to count. Therefore your 120Gb SSD has 120,000,000,000 bytes available to be used rather than the 128,849,018,880 that would be on a true 120GB SSD (SSDs do have this much, it's typically first level over provisioning though so you can't use it).

So if you do the math 128,849,018,880 bytes - 120,000,000,000 bytes = 8641620 Bytes / 1024byte/KB = 8439.08 KB / 1024KB/MB = 8.24GB

How much space are you missing again? ;)

I would double check the 520s though, I suspect that it isn't giving you a full 240GB like you're claiming it does since a lot of SSDs (not all) work this way.

it's normal for space to be "missing" because of what aquinus specified. My bet is you are just including that missing space when you say "windows and other stuff" it's likely part of that other stuff and you just don't know ii.

111GB

That's exactly what I get on my 120GB Kingston HyperX SSD for the reason Aquinus described plus the extra stuff that windows needs to reserve when creating a partition (a small space is marked as "system reserved").

well I'm missing 9gb worth of file so its 111gb/120gb well I don't understand much but my old external hard drive has 99xgb size out of 1tb I'll check tomorrow since I left it at work. so I was thinking something is wrong but well hdd are different from ssd's so XD..... but I was erxpecting to lose like 3-4gb instead of 9gb flat.

Like others have said, when a drive says 120GB, they actually mean 120,000,000,000 bytes. Since it's 1024 bytes to a KB (and so on) instead of 1000, you can divide by 1024 three times to get an actual storage size of 111.7587089538574 GB.

Edit: Just detailing it more.

120,000,000,000 bytes divided by 1024 = 117,187,500 Kilobytes
117,187,500 KB divided by 1024 = ~114,441 Megabytes
114,441 MB divided by 1024 = ~111.76 Gigabtes

Correct

And 117,187,500 Kilobytes equals 111.75871 GB

=))))) but still ssd's I look forward the future where there will be 1tb-4tb ssd at affordable price like todays hdd
