The OCZ Vertex 3 Review (120GB)
by Anand Lal Shimpi on April 6, 2011 6:32 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.
While our heavy 2011 workload may be a little heavy on the writes, the light workload is a bit more balanced. As a result we see the 120GB Vertex 3 move up in the charts a bit more. It's still not as quick as the 240GB drive but it's pretty much quicker than anything else.

Hello, I am looking for any OCZ, or other SSD for that matter, that has the Hynix H27UBG8T2ATR NAND devices as shown in the image above. I am willing to pay a bounty of $500 plus the original cost of the drive for one of these drives as long as it is still functional. Please contact me at 719-306-5539jamesearlywine - Monday, October 22, 2012 - link
I bought a vertex 2, and within 3 months the drive just stopped working. I was able to get a replacement from OCZ because the drive was under warranty, but I lost data.I recently bought a vertex 3 about 8 months ago, a couple months ago the drive began disappearing. My laptop would freeze, and when it rebooted, it didn't detect the vertex 3.
I've heard there's a firmware upgrade that might fix this, but I have to backup the drive, install the firmware, then restore from system image.
If you buy an OCZ vertex 2 or 3, make sure to backup your data regularly. I have been severely disappointed by how unreliable these drives are, I bought two, and both purchases have been bad experiences.

Hi Anand and everyone!! Thanks very much for this site. The amount of articles/comments here mesmerizing!Im having an issue with data transfer rates, and I cant get my head around it.
I really wanted to have better transfer rates on my desktop. Im not looking at RAID config at this stage.
I was hoping to get way above the 130 MB/s mark specially using sata III ports on my onboard Intel controller.
The motherboard is EVGA x79 Dark. And although I see spikes of 350MB/s on the first 3 seconds of the transfer rate (windows 8.1 copy details), its safe to say that most of the transfer is done at 130MB/s.
The BIOS has AHCI and ACPI enabled, and I checked that prior to the OS install.
Partition alignment on both drives seems to be ok (offset divisible by 4096) and both drives are about 1/3 from they total capacity. Both are 'twins' 120GB vertex 3 OCZ, purchased in one lot (but already about 3 years old)
The test i did was to transfer a 8Gb folder from SSD to the other. The difference I noted btwn copying a 8gb folder against a 8gb file is that in my case, the first 3 seconds are stable at 300+MB/s for the folder transfer, then it quickly drops to +-120MB/s till the end of the transf.
After reading this article, Im still unsure if I should go for another SSD brand (Samsung 840 pro or EVO), try an external sata controller.
Thanks!
