The delta between these two drives is relatively small with a queue depth of one—expected given the fact that we’re hardly exploiting the parallelism of a modern high-end SSD’s architecture. At the other extreme, pushing more concurrent requests bolsters performance across the board. However, the fact that we’re using 4 KB blocks of data is what really hammers the new Vertex 2 and its 25 nm NAND.
My theoretical explanation makes more sense next to the following chart, with the same test using 512 KB reads. Suddenly, the overhead is nowhere near as severe, and we see the new Vertex 2 faring much better, surpassing the older drive, in fact.

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.

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.
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.
Ok, but when will we be able to buy ssd's that are $100 @ 1TB capacity?

When blue frozen pigs fly in hell.
1.29 Firmware....how nice... pity that ocz only documents 1.28 for the moment.
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

in about 10 years or so....that's a very big maybe
Don't lie, Chris. We all know you still have (and love) that little Miata.

when you throw a shoes to bush again meaby lol
It is all about profit.
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.

Update your drive with the 1.28 toolbox--it'll show up as 1.29
Well normally moving to smaller production technology has mean better performance. I am not sure if the new situation where newer technolygy is inferior compared to old took manufactures by surprice?
But in anyway their own tests should have shown it...
Mazda did the same thing in 2004 with the RX-8. Originally advertised 255hp dropped to 238 and it offered to buy back cars.
Very bad move on OCZ's part. Justified or not, many people who hear this news will not be buying an OCZ drive.
Great article.
It appears as if OCZ was the first to market which would normally mean press releases, announcements, lots of hoopla, and technical reviews. Instead, OCZ chose to remain silent until customers complained. Silence had to be a management decision. What did management know?
BTW - Veteran posters at Tom's Hardware might remember what happened when OCZ acquired PC Power and Cooling. PCP&C had some of the best high quality power supplies available until OCZ acquired the company.
The same was for Toyota with his brakes problems few years ago.
OCZ is a good manufacturer, but at this point when they are out of the RAM business, they need fix that problems and avoid futures ones if OCZ as company wants be on the market for more years in future.
So they pushed out a cheaper less performing model with same name and stayed quiet about it, not the best way to get customers to return to the brand!
I don't like the idea of 25nm flash for several reasons, reliability is my main concern. Sure there are better block handeling in the last gen sandforce controllers (vertex3) but what about quicker dying cells and when the controller runs out of spare cells! When it comes to storage i rather let the tech mature at the expense of early adopters (paying betatesters!?) than have to restore an old backup and hassle with RMA.
The "mistake" by OCZ was not a mistake at all.
They are doing the same thing as before...
With their Rally 2 USB drives to be specific.
The Rally 2 did not have a model change at all (although it did have a different LED color), but users suddenly found out the new Rally 2 drives did not work in Xbox 360s and were slower.
OCZ has been great with their SSD customer support, but this fiasco was a huge slap in the face to all of their fans.
I know my next SSD will most likely be another brand unless the price is considerably less.
It will most likely be a Corsair, Crucial, or Intel. Corsair, because they were completely up front with their transition to 25nm and will also continue to have the Sandforce based chips for their future SSDs.
