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.

Exactly, and it's where power consumption matters even more.I'd also like to see where the OWC drives fit in.

There are plenty of lower pwer SSD's that have similiar tasty iops, so you won't be disappointed...the falvouring is a little different, but you will still enjoy it.ckryan - Wednesday, April 4, 2012 - link
I very much expect the next generation of Marvell drives to look similar in some respects to the V4.I applaud OCZ for doing things differently, but they're probably just trying to beat the next wave of Marvell powered drives to market, not making up for SFs immediate deficiencies.

Do you think Marvell can release a drive with as many delicious iops?Kristian Vättö - Wednesday, April 4, 2012 - link
Not Marvell, because they only make controllers ;-)Plextor M3 Pro is already providing up to 75K/69K IOPS (read/write). Marvell released a new controller a couple of weeks ago and at least according to the press release, random speeds should be substantially improved with a great firmware. How fast is still a question but I wouldn't be surprised to see figures similar to Indilinx 2.
And as a side note, Plextor M3 review should be up later today or tomorrow as well :-)

The M3P is fantastic. It's like the V4 without the compromise. Plus, I'd take better low QD performance any day of the week over high QD performance. The M3P is a lot more balanced.Plus, yeah, the 830 is awesome too, but it doesn't really cater to the super high 4Krw crowd. I feel like OCZ just needed to get this drive out before then next wave of similar drives hit, and will later tweak the FW to better accommodate desktop workloads.
But it does accomplish one thing -- whatever FW/FTL they strapped on that drive doesn't look like anything else at the moment. It's certainly easy to see in an ocean of charts.
I think OCZ just mainly wanted to reverse their years of SF marketing practice with the V4 -- Latency is now important. Compressible data is out. They just had to wait until they had a product that could match the paper specs of the 2281. Ironically, I'd take it over a V3 any day of the week, but the 2281 is still better with most workloads.

Perhaps the V4 may turn out to be a more economical choice though because it is entirely developed in house.jwilliams4200 - Thursday, April 5, 2012 - link
LOL. Except for the rebadged Marvell controller and the flash memory, yeah, entirely in house.rw1986 - Friday, April 6, 2012 - link
rebadged MRVL controller?? can u elaboratejwilliams4200 - Friday, April 6, 2012 - link
Did you ever wonder why Indilinx took so long to come out with a 2nd gen controller after their first was so popular?Well, they didn't. Not really. OCZ does not want you to know that they have a relationship with Marvell, and their new controller is basically a Marvell 88SS9187. It would be hard to justify the shareholder money OCZ spent on acquiring Indilinx if the truth were known.
If you have any doubts, look at the press release from Marvell press release bullet points and compare them to the features OCZ is touting in the Vertex 4. They are identical.
