AnandTech Storage Bench 2011 - Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011 - Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
Despite the reduction in large IOs, over 60% of all operations are perfectly sequential. Average queue depth is a lighter 2.2029 IOs.
The performance advantage over the RevoDrive 3 X2 drops to around 29% in our lighter workload. The narrowing gap makes sense given the workload here. There's less to break up and distribute among all of the controllers and thus we see less of a speedup.

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 :

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.
