OCZ Vector 256 GB Review: An SSD Powered By Barefoot 3

Tom's Hardware Storage Bench And PCMark 7

Storage Bench v1.0 (Background Info)

Storage Bench v1.0 is our home-grown trace, which replays the first two weeks of I/O activity on a desktop workstation. Because it includes several software installations, the trace incorporates quite a bit of compressible and incompressible sequentially-written information.

Based on the results of this test, OCZ's 256 GB Vector shows up at the top of the chart for the first time, though Samsung's 512 GB 840 Pro isn't far behind.

PCMark 7

PCMark 7 involves more compressible data, which is why SandForce-based drives jump up in the finishing order.

OCZ's Vector doesn't do quite as well in this metric, falling behind the 840 Pro and Vertex 3. Based on what we saw from the previous page, it's possible that the shorter duration of Futuremark's benchmark reflects the drive's reliance on foreground garbage collection, whereas the 840 Pro isn't incurring that overhead.

    "In the real world, it's almost a certainty that you wouldn't be able to tell the difference between them (or a number of the nearly-as-fast but tangibly less expensive models featured each month in Best SSDs For The Money)."

    This, This, This. All SSDs are pretty amazing at this point for me, the average user. What I care fare more about is - Are they reliable. At the moment, it still seems that Intel holds the reliability crown. Reviews like this are great, for sure, but they don't answer the most important question sadly.

    Let's make one thing clear. Endurance, reliability, durability, they all refer to different things.

    When it comes to reliablity, everything we know is rather anecdotal. There are no published RMA rates (only return rates and for a 500 sample size), so its rather flawed. Second, two users subject their SSDs in different ways. The first may have more random data in their workload. You can't make an evaluation that drive x failed for user y therefore its bad. What you do matters. Unlike HDDs, performance and characteristics of the drive change based on what you do to it. Since no two users do the same thing with their system, the only real way to test this out is to get a few thousand SSDs, subject them to the same workload in a big data center for a few years. I'd love to do this but naturally, it's really not feasible. :)

    So basically all good SSD's are constrained by the SATA3 interface. I cant wait for the direct PCIE interface(express pcie ?) to become standard.

    Do these drives (specially the Samsung 840) support TRIM in RAID 0 arrays or this is a property related to the chipset?

    That's a mobo thing. You're going to want a 7-series chipset from Intel.

    Jebus Samsungs are such strong contenders on all fields..

    i dont care how much slower the crucial m4 is compared to the new kids on the block, I will keep stocking them for myself and company, since that is the only one that has never failed me.

    Glad to hear the m4s are working out for you! Indeed, they have a pretty good track record.

    So should I buy some of thier stock now...? It can't get much lower than them going out of business from the lawsuits... :/

  • I just hope that there won't be as many firmware updates with this drive. I got tired of that with my past 2 OCZ SSD's (Vertex 3 & Vertex Turbo). It was way too often, almost as much as my GPU drivers. That being said, they both have given me no issues whatsoever and run like champs. I see a 256GB Vector in my future.
