Enterprise Storage Bench - Microsoft SQL WeeklyMaintenance
Our final enterprise storage bench test once again comes from our own internal databases. We're looking at the stats DB again however this time we're running a trace of our Weekly Maintenance procedure. This procedure runs a consistency check on the 30GB database followed by a rebuild index on all tables to eliminate fragmentation. As its name implies, we run this procedure weekly against our stats DB.
The read:write ratio here remains around 3:1 but we're dealing with far more operations: approximately 1.8M reads and 1M writes. Average queue depth is up to 5.43.
We don't see perfect scaling going from 4 to 8 controllers but the performance gains are tangible: +42% over the RevoDrive 3 X2 and nearly 3x the performance of a single Vertex 3.
Average service time continues to be where the Z-Drive R4 really dominates. The use of 8 controllers in parallel appears to be able to significantly reduce average service times when queue depths skyrocket. The R4 CM88 is now over two orders of magnitude (136x) faster than a single Vertex 3—and 227x faster than the Intel X25-E. Again we see that the RevoDrive 3 X2 is much slower than it should be here, possibly pointing at a firmware bug or some other enhancement on the Z-Drive R4.

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,

OOH OOH Let me guess!!!Never??
As in :

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.
