OCZ Vertex 4 Review (256GB, 512GB)
by Anand Lal Shimpi on April 4, 2012 9:00 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% | |||
Our light workload is far more representative of a mainstream client workload (read heavy) and this is where the Vertex 4's sequential read performance hurts it the most. The Samsung SSD 830 ends up being considerably faster here. Once again, if we look at the breakdown of reads and writes we see why:
Read performance is around half of the best performers, while write speed is around 30% better. The combination results in competitive but not class-leading performance.If OCZ is able to deliver, at a minimum, Octane levels of read performance, the Vertex 4 should find itself much higher in the overall charts.

Until this has been out a year, that's all this amounts to.I'd rather pay for Intel/Crucial reliability than be OCZ's unpaid beta tester.

The previous poster was correct, OCZ fixed the BSOD problem, not intel. Sandforce then released their fix to the other Manufacturers. Sandforce was the problem.... fact. So far all feedback is great with the Vertex 4, if that continues until Ivy Bridge and nothing better comes out, I'll be getting one! Vertex 3 and all other SF-2000 based SSD's showed problems right away, so I'm not worried.alfatekpt - Monday, April 9, 2012 - link
Why is your recommendation the Samsung's SSD 830 instead of OCZ vertex 3?Reliability?

It's interesting to see the max values of power consumption, but it would also be interesting to factor in the speed of the drives.Usually a desktop user have a fixed amount of data that the disk needs to transfer, so continous load wattage is not that interesting compared to how much energy that is required to get the job done.
wattage * transfer time
For continous loads it would be more interesting to see something like
transfer speed / wattage
How much performance do I get compared to the energy I put in?
I could do these calculations manually of course, but I don't know how the write tests in the power consumption part are performed, so I cannot get the speed data from other charts.

An SSD will be idle nearly all the time in nearly all desktop and laptop use cases. When the idle power consumption is > 1W, it doesn't much matter what the load power consumption is.Winning29 - Monday, April 30, 2012 - link
Hey guys. Check out my OCZ Vertex 4 speed test on YouTube. It shows my home PC's boot up time, then I load a VDI environment running on Citrix XenApp and VMware Workstation.http://youtu.be/YrnIcudM7zo
I'd welcome any comments, feedback or questions.

New firmware 1.4's out, does it fix the low queue depth sequential read performance?twindragon6 - Friday, June 29, 2012 - link
From OCZ's website."CURRENT FIRMWARE RELEASE is v1.4.1.3"
I'm curious to see how this drive performs now with the newer firmware.
