OCZ Vertex 4 Review (256GB, 512GB)
by Anand Lal Shimpi on April 4, 2012 9:00 AM ESTPCMark 7
The storage suite in PCMark 7 validates a lot of what we've seen thus far. Despite great write performance, the Vertex 4 can't outperform the Vertex 3 because of its read speed limitations. From OCZ's perspective however, the gap is narrow enough in overall tests to make the shift away from SandForce likely worthwhile. The Vertex 4 doesn't care about compressible vs. incompressible data and it keeps more of the drive's BOM cost in house compared to the Vertex 3.
It's worth noting that for sufficiently light workloads, the difference in performance between any modern SSD is going to be limited right off the bat. We're talking about a 6% spread between the slowest and fastest drive here. For many users, simply finding the right balance of price and reliability is sufficient - which happens to be one of the reasons we've been such big fans of Samsung's SSD 830.

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.
