OCZ Vertex 2 SSD (How to check if 25nm or 34nm ?)

post #1 of 7
Thread Starter 
I have a 240GB Vertex 2 , how do I know if it's 25nm or 34nm ?
post #2 of 7
It's 34nm.

We should note that this only effects smaller capacity drives. 2.5" and 3.5" drives in 60 and 120GB capacities are effected.

The new drives have a shiny reflective metal strip along the sides where the mounting screw holes are. The 34nm are all matte black.

The 25nm drives have an extra "E" in the part numbers too.

Check out these charts.

There is also a new model designator. the model number now has a ".M" at the end of it.

The .M at the end of the part# means it is 3Xnm NAND and 32Gbit die process. I'm getting 120Gb .M parts back from RMA'ing 2-100Gb Vertex2's with 64Gbit die process.

Correct. Didn't realize my post sounded like it was part of the answer rather then another piece of info.

I have 8 of the ".M" drives and one of them failed in less the 3 hours Not excited/confident about this batch yet. Hopefully I just got one dud in the group and its not indicative of anything more .
