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.

The Vertex 4 does have a Marvell controller, with Indilinx firmwareDenithor - Wednesday, April 4, 2012 - link
You seem to have forgotten Octane, 'the 1st time that ocz now owns the controller and firmware that goes into the product.'And, as far as I've heard, Intel was the only one to truly fix the BSOD associated with the SandForce controller. Others made improvements and reduced the frequency but Intel downright fixed it.

I'm not buying a controlled, I'm buying an SSD, and they delivered a crappy SSD, why should I trust OCZ now?semo - Thursday, April 5, 2012 - link
Yep, OCZ are smiley and I won't buy a product from them as long as there are competitive alternatives. They still haven't issued a mass recall of their first 25nm drives which did not have as much capacity as per their specs. OCZ blamed it on Sandforce's RAISE technology and waited for customers to contact them before replacing the affected SSDs. No one knows how many of those duds were sold and how many were replaced.kristof007 - Thursday, April 5, 2012 - link
I've been using my Vertex 2 for just over 2 years now. 120GB model. Not a single hiccup. I'd call that fairly reliable.PaulSabey - Wednesday, February 27, 2013 - link
My 120gb Vertex 2 (bought March 2011) had been running without a hiccup for nearly two years. Then yesterday it just spontaneously failed (BIOS could not even see the drive as present). I guess you can think your drive is totally reliable .. until the moment it fails.Breach1337 - Saturday, April 7, 2012 - link
Same here.Vertex 3 owner - although a great product for months I had a unfit for purpose product, no support and no fix from OCZ and on top of that people were treated with utter condescending arrogance on the forums, asked to effectively troubleshoot the product and if you refused to do that you were not cooperating. Sorry, but never OCZ for me ever again.pattycake0147 - Wednesday, April 4, 2012 - link
I can live with the lower read speeds, but the power consumption is too high. That said if reliability holds up, sounds like I'll be getting a new drive this year.Great review Anand!

If this was going in a laptop, MAYBE I would be concerned, but what's a few watts for some more tasty iops?pattycake0147 - Wednesday, April 4, 2012 - link
A laptop is exactly what I would like to use it for. Both of my desktops already have SSD/HDD combos.
