The OCZ Vertex 2 Conspiracy: Lost Space, Lost Speed?
Several readers contacted me in the past two weeks, complaining about OCZ's recent adoption of 25 nm NAND and its effect on the capacity and performance of certain SSDs that they expected to be both larger and faster. I bought my own drives to compare.
Benchmark Results: Iometer Streaming
If the previous page got you worked up, then this page of results should help confirm that we’re onto something here. Streaming IOPS and throughput are fundamentally unchanged in shifting from 34 nm NAND to the new 25 nm devices.
The same goes for writes. There’s basically no change. It’s definitely much more conceivable now that the problem stems from processing overhead associated with smaller randomized files and more aggressive ECC.

Mushkin.com have a letter posted on the website that they will not be going to 25nm as the drives life cycle is less than half that of a 3*nm drive. Also the performance is not there.Reply

Depending on supply of 34 nm NAND, that's probably not a sustainable position to take. IMFT isn't going to decide to shift back to 34 nm.
At the risk of contradicting myself, Intel will be using 34 nm NAND on its next-gen 6 Gb/s Elmcrest drives. It's not like the flash isn't disappearing entirely, but the vendors making the switch seem to be motivated largely by cost-cutting reasons. -
Nicely done Mr. Angelini; however, I still think OCZ pulled a nasty car-salesman tactic on their newest 25 nm NAND SSD products, and as such will be looking elsewhere to purchase any future SSD. Blaming resellers or other sources for the SKU is an incompetent way of deflecting fault and has made them look even more silly.Reply

cangelini Thanks radiovan. Like I mentioned in the story, we'll have to see if companies like Corsair and Patriot are able to get their upcoming renamed SKUs onto Newegg, Tigerdirect, Zipzoom, etc.Reply -
1.29 Firmware....how nice... pity that ocz only documents 1.28 for the moment.Reply
And then again why not update the 25nm to 1.29 too?
But I guess consistency is not always wished when trying to demonstrate something -
nebun binoyskiOk, but when will we be able to buy ssd's that are $100 @ 1TB capacity?in about 10 years or so....that's a very big maybeReply -

when you throw a shoes to bush again meaby lol

Reynod It is all about profit.Reply
The real reason is that going to cheaper flash with a 3000 cycle life to reduce the total cost of production (and therefore increase profit) means ... increasing the amount of redundant memory to replace the flash that dies due to wear ... and that process means better error correction is required to achieve that ... therefore performance is effected.
Chris ... I got it into one sentence ... albeit a horrible one.
Nice article mate.
