SDD smaller than it should be?

So. I'll start by saying that I know absolutely nothing about SSDs, so please be gentle

I've got an Intel SSD, a SSDSA2MH080G1GN. It came from a pile of leftovers, and is marked as an engineering sample. It looks as though it's supposed to be 80Gb, but it'll only show up as 29.8Gb in Windows.

I've tried resetting the partition in disk management, to no avail. Am I stuck with this thing being 30Gb, or is there something I've missed?

G'day

It could be that 50GB was excluded for testing or other purposes and the way to set this (or remove it) is usually with the manufacturer's toolkit, it's called a HPA (Host Protected Area)

http://en.wikipedia.org/wiki/Host_protected_area

Alternatively, if there is no HPA I would be guessing that as an engineering sample it could be that 5/8 of the total chips on the board are DOA and they configured the SSD to use the remaining 3/8 chips, so it's something to play around with but not store real data on, otherwise you could use it as a SSD read cache on a Z77 chipset board.

Well, after a bit of experimenting, it looks as though the drive may be cactus. Read and write speeds are all over the place, with a 5.4Gb folder taking almost 5 minutes to copy.

Noted above, look into the HPA - IIRC, hdat2 can inform you and remove it easily if there is one.

It may just need a secure erase to restore some speed, too (G1 in model number indicates it's the pre-trim supported era, so this issue was fairly common).

After a bit of digging around with hdat2, I've made a bit of a discovery - the model number that's printed on the drive is different to the number in the firmware. Whereas the sticker says SSDSA2MH080G1GN, hdat2 says SSDSA2MH032G1GN, which squares up perfectly with the drive being about 30Gb.

Not really much you can do with a 30Gig ssd :/

Yeah, it's a bit annoying. I could use it as a system drive, but it'd be difficult. I'll probably end up selling/giving it away.

hyberfil.sys and pagefile active?

Mine was using up 16gb pagefile and 16gb for hibernate.. Got rid of both and now have another 32gb free

Maybe that's what eating up my 80gb Intel!

I just disabled Hibernation on mine cause it was chewing up 8GB:

1. Open a Elevated Command Prompt.
2. In the elevated command prompt, type powercfg -h off and press Enter.

No, it's a blank drive. I did a secure erase with intel's ssd toolkit, which picked up transfer speeds a bit, but it's still sitting on 30gb overall...

Thanks

Went from 11gb free to 18gb free.
