OCZ Vector (256GB) Review
by Anand Lal Shimpi on November 27, 2012 9:10 PM ESTSequential Read/Write Speed
To measure sequential performance I ran a 1 minute long 128KB sequential test over the entire span of the drive at a queue depth of 1. The results reported are in average MB/s over the entire test length.
Low queue depth sequential read performance is among the better drives, but still slightly behind Samsung.
Write performance continues to be the Vector's strong suit, here only Intel's SSD 520 with easily compressed data pulls ahead.
AS-SSD Incompressible Sequential Performance
The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.
High queue depth sequential IO shows significant clustering at the top of the charts thanks to the limits of 6Gbps SATA. The Vector pushes performance pretty much as fast as possible here.
Switching to writes does shake loose some of the weaker competitors, but the Vector and 840 Pro still emerge as the strongest. Corsair's Neutron GTX does very well here.

A 5 year warranty is a pretty solid commitment on the part of a manufacturer. I don't think they would have done that if they didn't trust the stability of the hardware, so they really put their money where their mouth is.Other thing: is the Indilinx co-processor 'Argon' or 'Aragon'? Pic differs from your text description.

Nah, you've got it all wrong unfortunately - they've bet the farm on this drive and if it fails they won't be around in five years to honor those warranties.When you've got nothing, you've got nothing to lose.

Well that, but I'm glad to see OCZ committing more to their drives... on my local price price check there's Agility, Colossus, Enyo, Ibis, Lightfoot, Octane, Onyx, Petrol, RevoDrive, Synapse, Vertex and Z-drive not counting numbering or variations like Vertex EX, Vertex Limitied Edition, Vertex Turbo and using a zillion different controllers and stuff. The warranty is also an indication this is the technology they'll continue working on and fixing bugs for, which is good because their attention span has been too short and spread too thin. It's better with a few models that kick ass than dozens of models that are all shoddy.MrSpadge - Wednesday, November 28, 2012 - link
Some of the drives you list are several years old..JonnyDough - Friday, November 30, 2012 - link
Furthermore, the Intel 520 (which I just purchased) got dropped off the enterprise iometer 4KB random write chart. That don't make a lick-a sense!Hood6558 - Wednesday, November 28, 2012 - link
alacard may be right, OCZ is sliding closer to the cliff as we speak. There's so much competition in the SSD market, someone's got to go sooner or later, and it will probably be the less diversified companies that will go first. I recently bought a Vertex 4 128 for my boot drive, and it lasted only 15 days before it disappeared and refused to be recognized in BIOS. The Crucial M4 128 that replaced it has the problem of disappearing every time the power is shut off suddenly (or with the power button after Windows hangs), but comes back after a couple of reboots and a resetting of your boot priorities. And it's regarded as one of the most reliable drives out there.So in order for OCZ to remain solvent, the Vector must be super reliable and stable, and absolutely must stay visible in BIOS at all times. If it's plagued by the same problems as the Vertex 4, it's time to cash out and disappear before the bankruptcy court has it's way.

Windows hanging? I smell problems with the user...djy2000 - Wednesday, July 31, 2013 - link
That warranty doesn't cover the most important thing. The data on the drive.Bull Dog - Tuesday, November 27, 2012 - link
Is that an m-SATA connector on the other side of the PCB?philipma1957 - Tuesday, November 27, 2012 - link
good question if I open the case can i use this as a msata?a 512gb msata is very hard to find.
