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

Less than two years after acquiring Indilinx for $32 million in stock, OCZ is ready to introduce its first SSD based on controller technology developed in-house. Can its new Barefoot 3 propel the 256 GB Vector we're testing into a performance victory?

Power Consumption: Idle And PCMark 7

Idle Power Consumption

Because SSDs are so fast, they sit idle most of the time. In almost our almost 30-minute virus scan, the SSD is only busy for 281 seconds. As a result, idle power consumption is the most important figure to consider in a desktop environment.

We've already seen Samsung's architecture fare particularly well in idle power measurements, despite its beefy triple-core ARM-based controller. In comparison, the Vector doesn't do quite as well, suggesting it might not be as suitable in a mobile environment. Even though it delivers performance that comes close to Samsung's 512 GB 840 Pro, OCZ's Vector requires 2.6x as much power at idle.

PCMark 7 Power Consumption

Again, even as the Vector serves up performance that approaches Samsung's flagship, it requires ~28% more power under load to do so. Both drives dip in under the 1 W mark, so the absolute difference is still small compared to a CPU or discrete graphics processor. However, it's still clear that Samsung has an advantage in efficiency, especially if you're looking for an enthusiast-oriented SSD for your notebook. 

If you shift the comparison to SandForce-based SSDs, the Vector is on par with OCZ's older Agility 3 drives, edging out the slightly more power-hungry Vertex 3 and SSD 520.

    "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.
