Vertex 2 - which version do I have?

[pinkfloydhomer]

I recently bought a OCZ Vertex 2. As far as I understand, there are three versions of this drive:

1) The original 34nm version
2) The controversial first 25nm version that was slower and had less usable space
3) The updated 25nm version that is supposed to be as fast as the original and have the same amount of usable space

Also, OCZ is offering free replacements of 2) to 3). But how do I know if I have 2)?

How can I tell which version I have?

Well you answer your own question.. "[..] had less usable space"

So just check if the usable space corresponds to the correct drive size or not - that's the easiest, although in theory you could download some OCZ tool for it as well.

easy rule of thumb is to multiply the drives capacity(you didn't say) by .93 and see of it jives with what the OS shows. affected 60 gig drives are showing 51GB instead of the typical 55 and affected 120's are showing 107 instead of the typical 111GB.

is a PITA to deal with I know, but is pretty painless otherwise. Good Luck with it.

Which incidentially is only true for Windows drives not most linux distributions (no idea about macs), so you'll have to differentiate there.

I have the 120 GB and Windows says 111 GB, so far so good. But do I have the 34 nm or the 25 nm, then? Just want to be absolutely sure I have the newest version.

The 25nm version is newer, but isn't better. Only OCZ benefits from you having the 25nm because it's cheaper for them to manufacture while providing no benefits to the end user. The 25nm also has fewer number of write cycles available(5,000 vs 3,000) compared to the older Vertex 2s. But as far as I know, the only way to really know what kind of NAND is being used is to open up the drive and look at the markings.

The 25nm version is usally also a bit slower (though by far not as extreme as the lower channel variants) for sequential writes at least, so running AS SSD can give some indications.

Does anyone know what the size difference will be for non-Windows OSes? I have a Vertex 2 coming in two days and I don't want to buy Windows just to see if I got screwed.

Maybe I should just not check. Whole reason I bought OCZ is how well they work in a TRIMless environment (in my case OSX) so its not like I have other options....

Assuming your "non-Windows" OS is a current Linux distribution it should denote the units correctly, i.e. GB are base10 and GiB base2, so you'll just have to look at the unit.
