AS-SSD Incompressible Sequential Performance
The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.
Throwing incompressible data at the controller is another way to get it to shine. With less data that can be thrown away, there's more parallelism to be exploited by the controllers. What results is huge performance - over 2GB/s in the read test and 1.6GB/s in the write test. Note that these scores are more than twice that of the RevoDrive 3 X2 - perhaps due to the use of asynchronous NAND in the RevoDrive 3 X2.

I agree 100%GTRagnarok - Tuesday, September 27, 2011 - link
"We have a preproduction board that has a number of stability & compatibility OCZ tells us will be addressed..."I think a word is missing here.

Also, you missed the protocol on the last link on the first page (the one to ssd bench) and it 404's nowAnand Lal Shimpi - Tuesday, September 27, 2011 - link
Fixed both! Thank you!Take care,
Anand

OOH OOH Let me guess!!!Never??
As in :
"We have a preproduction board that has a number of stability & compatibility OCZ tells us will NEVER be addressed..."

Isn't it the fact that the revodrive 3 x2 use asynchronous memory that makes it so much slower than the r4 ?Anand Lal Shimpi - Tuesday, September 27, 2011 - link
Great catch! I hadn't even thought of that but it's definitely a possibility :)Take care,
Anand

I just can't take OCZ seriously from a reliability standpoint. I would love to know what the failure rate is like on OCZ's desktop offerings. I personally am in the process of my 3rd RMA of an OCZ SSD during the past 2 years.I think Intel, Crucial (or, judging by the last review, Samsung) will make my next SSD. I can only rebuild windows and piece together backups so many times before I say enough is enough.

What's the point to develop enterprise product if no enterprise is going to buy?I don't think any enterprise will trust OCZ.
