OCZ Agility 3 (240GB) Review
by Anand Lal Shimpi on May 24, 2011 2:53 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.
In our light workload the performance gap is a lot closer between the Vertex 3 and Agility 3. For typical desktop usage, the Agility 3 is likely indistinguishable from the Vertex 3.

Seeing Vertex 2 120G and Agility 3 120G at the same price, which one should i buy ?BTW : no sata 3 motherboard at the moment, so choice shouldn't be based on it.

I sure hope the Agility/Vertex 3 drives are more reliable than the Vertex 2 is. I had one fail two weeks ago, and then the replacement I got last Wednesday failed on Saturday. I believe it happened when we had a momentary interruption in power. The laptop and secondary-bay HDD are fine, and the drive kept working until I shut it down; once I did so, the drive became totally unresponsive.The drives also can't handle ATA Password properly:

From the forums and Newegg's reviews, it looks like plenty of other people have similar issues. For comparison, I've had zero issues with my old Indilinx drive. I like the performance of the Vertex 2, but I don't feel confident in the reliability of any Sandforce drives now.
Anand, can you please talk to the OCZ people about these sorts of things?

Firstly, I really appreciate AT's in depth reviews. That said, I absolutely agree with DanaG, and I don't see reviews addressing the reliability of these drives--particularly SandForce ones.I'm pricing out two new computers at the moment, and have been surveying the SSD landscape. If I made a buying decision purely on this review and others that focus on performance I'd already have ordered a Vertex 2 or the like, but after reading enough about failed drives, there's no way I'm buying anything with a SandForce controller for a good long time.
Based on the sheer number of anecdotes I'm seeing I find it odd that reviews aren't even mentioning the issue of reliability. 6 out of 10 of the most recent comments on Newegg for the OCZ Agility 2 are complaining about outright failure (in some cases replaced drives also failed), or major problems using the drive.
That sort of track record is embarrassing in a retail product, and really makes me wary about the reliability of the technology overall. Compounded with the apparent fact that data on a bricked drive is irretrievable in many (the majority?) of cases, and you really have to think twice about using one.
Given all this it's kind of amazing, and downright laughable, that some of these drives are supposedly targeted at enterprise level customers.

For all those looking for a Corsair Force 3 review, the first on is now online: http://www.kitguru.net/components/ssd-drives/zardo...Seems performance is very similar to the Agility3 reviewed in this article, although the Force 3 reviewed in the article is a 120GB

Can tell me the preconditioning for the random read test and the preconditioning for the random write test used here?Thanks,

Mine died after 4 months. OCZ used "unauthorized reseller or warranty not transferable" to stop all the claims. I was problem ticket no: 240 526 and it keep rising fast. See OCZ discussion forum before you buy as these SSD from OCZ are still very unstable.jdtwoseven - Wednesday, August 1, 2012 - link
I've had three OCZ SSD products, including one of these Agility 3 240 gb SSDs, and I've ended up having to RMA each one of them. That is a terrible record of reliability for the drives. The amount of time that it took to get a replacement was also painfully slow. Not good. Buy a Crucial M4, which is what I did while I was waiting. The Crucial M4 is fast, and I've had no problems at all.ByronArneson - Friday, October 7, 2016 - link
Thank you for perhaps the most level headed thing I have read today. I also can share my experience in filling forms. I've found PDFfiller - online service for forms filling. It's pretty easy to use and pretty cheap. You can find fillable a form here "https://goo.gl/yPbFZS".davodamirajam - Monday, January 29, 2018 - link
