OCZ RevoDrive Hybrid: Solid-State Speed With Hard Drive Capacity

SSD Caching: Application Performance

Our Photoshop benchmark slightly mirrors the results from PCMark's Memories Suite, but the small performance difference requires some explanation. What we're really doing here is measuring the time it takes to apply four filters to a 14 MB TIFF image using an automated script. As a result, a large part of this benchmark is CPU-bound, and doesn't show a speed-up due to caching.

However, this doesn't tell the complete story because the time it takes to load Photoshop does improve by roughly one second. The problem is that, on average, there's a one-second variance in executing the full batch file, so it's hard to discern any advantage.

Due to the lack of granular information in our Photoshop benchmark, I went ahead and programmed a new WinRAR test to measure time in milliseconds. Here, the performance benefit from caching is more obvious, and OCZ's RevoDrive Hybrid takes the lead once we move out to the fourth trial. However, we're still looking at time in fractions of a second, so any performance boost in this test, which isn't I/O-bound, is marginal at best.

There's a love/hate relationship with anti-virus software. Yes, it helps keep us safe. But it can also affect system responsive due to the highly-random read nature of the workload.

As such, it's no surprise to see a full drive scan take nearly 15 minutes when we use our hard drive alone. With caching enabled, performance surges nearly to the point of using an SSD. The RevoDrive Hybrid does remarkably well in this regard. While it's hard to make out in the graph, the Hybrid outperforms the Z68 with write-back caching by roughly 20%.

    This should be compared with the Seagate Momentus XT, where's that?

    Except for those who don't have SATA 6GB/s controllers on their motherboards, this product is a little redundant.

    I mean, it's really cool and all, but since Vertex 3 drives on their own run about 200 bucks for 120GB, you could get 2 x OCZ Vertex 3's in RAID, and a high-performance 1TB 7200 RPM drive like the Western Digital Caviar Black (the one mounted there is 5400RPM) for the same price as this drive.

    So instead of the rather limited 120GB, you'd get 240GB of SSD storage instead, along with a faster hard drive. Because with 240GB, who needs cache?

    than i believe use a raid 5, i think thats it, raid the 2 ssds and get another hdd in there as a backup for the two ssds

    For a raid 5 at least 3 drives is needed. And the chipset integrated raid5 solutions don't have powerful checksum offloading either meaning its either slow or hogs the cpu. Sure raid 5 is awesome in its ways but it also has its drawbacks.

    Just raid 0 and actively backup important files yourself if you can't take the drawbacks of it.

    If something just created is really worth saving, save it twice. Else just a back up image per week.

    ..

    It should be !


    Also why use 5400rpm? why not 7200rpm? Or use the XT.


    To me, this product looks like its hurting. Overpriced.


    I tested a few of the XT's are they are quick. Pretty much constant 100+ data and super low latency on common tasks.

    Could you please look at a direct comparison with the Momentus XT please?

    I have one as well.

    From what I can see this is a bit better than the XT but it would be good to know Andrew.

    Cheers !
