Title: OCZ's new 25nm chipped SSDs Post by: Calibrator on February 19, 2011, 06:06:21 am Those contemplating a purchase of a new small capacity OCZ SSD would be advised to read the following first ...

OCZ now offers RMA swap from 25 to 32/34 nm. Mine that was bought six months ago is 25 nm version. This shady marketing tactic will definitely tarnish their reputation. http://www.storagereview.com/ocz_issues_mea_culpa_offers_free_ssd_replacements Thanks again Praphan Title: Re: OCZ's new 25nm chipped SSDs Post by: Marcin_gps on February 19, 2011, 09:29:14 am Hi guys,
Personally I wouldn't go with this 'old' equipment. I'd wait for Vertex 3 Pro, that's going to be released soon: http://www.anandtech.com/show/4100/ocz-vertex-pro-3-demo-worlds-first-sandforce-sf2000 Look at the specs and first benchmarks :) Marcin Title: Re: OCZ's new 25nm chipped SSDs Post by: Calibrator on February 19, 2011, 10:25:51 am Thanks for the link Marcin. Looks good on paper but like most of these early reports I expect a difference with final production examples. No doubt there will be a premium associated with the new technology and to get the best from them you will need a m/b with appropriate controller. Still, it's a nice advancement and will hopefully drive the prices of their, and other manufacturers, drives down across the board.
The response improvements going from spinning platters to SSD is very noticeable. Going from SSD to these new drives more of an incremental step I expect. Will need to wait a few months I guess. BTW ... anyone running OCZ drives should make the effort to get on the latest firmware. Only gotcha, is that you need to be on an internet connected PC, so in my case i disconnected the drives from my music server and installed temporarily into another PC. OCZ reckon you shouldn't lose data during f/w upgrade but I took a full backup as a precaution (which wasn't needed). Cheers, Russ Title: Re: OCZ's new 25nm chipped SSDs Post by: manisandher on February 19, 2011, 01:26:40 pm I use a Vertex2 90GB drive in each of my two 'music servers'. But these are 3.5" SSDs, not 2.5" ones. Does anyone know if there is a potential issue with these 3.5" drives?
Also, how would I know whether these drives are the 34/32nm or 25nm variety without openning them up? Is it just a case of looking at the formatted capacity? Well, mine are 83.8GB. Does this indicate which variety they are? Any help most appreciated. Cheers, Mani.

But in the example given I didn't see that "E". But maybe I didn't get it well, and was it just about that "E" which should be there, but isn't (always) ?
In an earlier example that "E" was there though ... Title: Re: OCZ's new 25nm chipped SSDs Post by: manisandher on February 19, 2011, 02:21:11 pm Huh ? do they exist ?? Yep: http://www.ocztechnology.com/ocz-vertex-2-sata-ii-3-5-ssd.html (although mine are housed in the 'discontinued' case). Test the speed. :swoon: I don't have any specific software to do this. However, my Windows Index score is 7.2. Looks OK to me, though I doubt it indicates 34/32nm vs. 25nm.... Mani.
