The SandForce Roundup: Corsair, Kingston, Patriot, OCZ, OWC & MemoRight SSDs Compared
by Anand Lal Shimpi on August 11, 2011 12:01 AM ESTAnandTech 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.
As the only 240GB drive running 3.20 the Kingston HyperX is the fastest drive in our test here (only the Vertex 3 and possibly the Corsair Force GT even have 3.20 available for update). The advantage is still pretty small though, at 6% above its closest competitor in an IO bound test you'll never see that advantage in the real world.

Thanks for the great review Anand! I'm rocking a Patriot Wildfire 240GB in my 2011 15" mbp (2.2ghz, 8GB, 6750m 1GB, 1680x1050 anti-glare) and it's been 100% perfect. I haven't seen any errors whatsoever in snow leopard, lion, and windows 7 via boot camp.These benchmarks are pretty consistent with what I see on my own drive, although the 240GB is a bit higher all around. :)

Here is a good summary of the issue to date:From Ocz:
'...I think the ultimate fix will come with a FW coupled with Orom change and new RST/IME driver and possibly UEFI update for the motherboards, the issue needs to be nailed down, at this time its floating around with Orom changes etc and what ever SF do can be countered by what the Orom is doing...and yes SF are talking to Intel so i would hope between them they can get it worked out....

Was gonna post this as well as the likely cause for the problems with the Asus board.Then again, if the Intel H67 is your testbed Anand, have you even updated the BIOS or are you staying with an older one for comparability? With an older BIOS it might have an older OROM as well and thus the issue could then not be solely caused by the OROM.

Thank you for another great write-up, Anand!I'm curious why you left the Corsair out of several of the benchmark results (4KB Random Read, 128KB Sequential Read and Write)?

maybe because it preformed worse than expected and the site got a little bribe from Corsair not to publish but instead put a nice commercial on the last page?philosofool - Thursday, August 11, 2011 - link
Don't be a jerk. If you're going to accuse someone of something like this, have some evidence.Anand Lal Shimpi - Thursday, August 11, 2011 - link
Or because I accidentally put the wrong graphs in the piece :) It has been fixed.Take care,
Anand

Sorry but the current SSDs are unreliable at this point in time and it's unscrupulous to continue selling these SSDs when a mfg. doesn't know the root cause, have a resolution for the operational/compatibility issues and can not tell consumers what systems can use these SSDs without issue.It's good to see Anandtech substantiate what I have been saying for some time. Now consumers need to stop purchasing these SSDs until they are properly revised so they function without issues for everyone.

SSDs offer amazing performance, but too many of them are cursed with reliability problems. A is faster than B at price point C is not sufficient to make buying decisions with SSDs. When and how can benchmarks examine SSD quality issues?Axonn - Thursday, August 11, 2011 - link
Why is the Corsair Force 3 in only 1 of the benchmarks @ Random/sequential speed? And I can't see the Corsair GT anywhere on the first page?
