The 2011 Mid-Range SSD Roundup: 120GB Agility 3, Intel 510 and More Compared
by Anand Lal Shimpi on June 7, 2011 12:52 PM 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.
Under more typical desktop usage models the Vertex 3 is the fastest, but not by a huge margin. The Agility 3 and Intel SSD 510 are both within 10%. The major advantage for OCZ here is in read performance, which is what you do most of the time with a desktop (non-file archival) workload:
Write performance is clearly not one of the Vertex 3's strong points, at least compared to the 510 and Corsair P3 - both of which deliver top notch performance here. Despite using identical controllers, there is a tangible performance difference between these two drives.

"It's funny how little the recommendations have changed over the years. Intel still offers a good balance of performance and reliability, however if you're willing to take a risk on the reliability front you can get better value elsewhere."http://www.anandtech.com/show/2738

Looks good. I recently got a 160GB Intel 320 drive for my M18x but since it has Sata 6Gbps I am going to be pretty tempted to trade up to a 510 down the road. Just could not get excited over that $$/GB for nowStargrazer - Tuesday, June 7, 2011 - link
Awesome. Thanks.(first (non-french) comparison of current-gen ~128GB SSDs I've seen)

Anand,Thank you for this! This is exactly what I have been waiting for.

The chart labels on page 5 are conflicting with both charts being labeled read/write write/read with the inverse white on orange text being correct and the black on orange text being incorrect.Anand Lal Shimpi - Tuesday, June 7, 2011 - link
Fixed :)Oxford Guy - Thursday, June 9, 2011 - link
240 GB Vertex 2 at some point... prettie please?You talk about the 240 GB drives offering best case performance. Don't you think people would like to know how good the performance of the 240 GB Vertex 2 is in comparison with 120 GB next-gen units like these?

For me this article gives weight to the research I have done and the hours reading and analyzing other reviews.For the laptop I had chose the Intel 510 because it has the least power draw idle, 6 Gbps and a proven track record of reliability.
For my gaming machine I had chose the Vertex 3 240gb. Even with the reliability issues that might happen I have nightly backups running (Easy to setup with Windows 7) and spare drives to swap in should something happen.

One of the things that's held me back from getting an SSD is that I always have at least 2 OSes installed, and a common data partition. Can anyone point me at info on how these drives handle that? I can't find anywhere that Anand has covered it in his roundups. I'd like to know how it affects performance, but what I'm really concerned about is drive life, if the partitioning interferes with the controller's ability to optimize wear leveling.cgeorgescu - Tuesday, June 7, 2011 - link
It's amazing how a Corsair Force F120 (or some Vertex2) still manages to not be beaten that hard by these new arrivals. In pure benchmarks, the new drives have some impressive results but, as long as we're speaking about real-life scenarios, F120 suddenly appears in the graph not far under the new drives.
