    554 ms average transfer speed and 5.6ms access time. Very pleased with the speed and space.

    Not to bad. Comparable to my single Samsung 830 SSD, but you get points for volume. I wish I had 2TB at that speed. Hope you're keeping backups! :D

    What's your random read and write times look like?

    I used hd tune to benchmark. What do I need to use to measure that?

    Not really. Still limited to a few dozen IOPS. Like 200 tops.

    Your 830 will do a couple dozen... thousand.

    Random IO is, sadly, what the user experience is all about.

    Any commonly used SSD benchmarking tool (AS SSD for instance) will benchmark a hard drive too.

    See this thread for an example.

    A friend of mine RAID 0'd (is that a verb?) four garden-variety 500GB Seagates and was content with the result. Then, on a whim he got a 32GB USB3 flash thumb drive and just used it for Readyboost. He was stunned at the improvement. He got a hybrid hard drive experience that is better than the hybrid hard drives that are out there.

    I wouldn't trade one SSD for all the RAID 0 Velociraptors in the world. It doesn't matter how many you put in your array, Access times, IOPs and Random Read/Writes are always going to suck in comparison. Then there's the noise..

    Everyone is entitled to be different. I do not have a noise problem.

    I surely would if I wanted TB's worth of fast storage.

    and all the rest of that stuff won't matter much for a storage only volume.

    Not to mention if you combine raided SSD for OS use.. with raided HDD for storage?.. the bar get's permanently raised.

    PS. I've got 23 drives INSIDE my case and 14 of them are raided HDD combo's. No noise issues here either.

    Its a fact that Multiple drivers in Raid 0 will be louder than a single SSD or multiple SSD's since they have no moving parts.

    So when you say you don't have a noise problem you mean you are ok with it and don't mind it.

    And I agree with everyone else Raiding raptors is so 2006-2008 SSD's are where its at now!

    No, I'm saying that I do not hear them. They did not have the redesigned Velociraptors with 64 cache in 2006-2008. I know SSD's are fast,but I chose to be different. To each his own :)

    Indeed!

    You will still have impressive performance for a hard drive based setup :)

    Nice 4x VRaptor RAID0, what do you store on it?

    Here's my 2x 1TB VRaptors RAID0 array. I shortstroked it down to 1.4TB to make it even more consistently faster!

    I use it to store Steam games. Works amazing, all the time.

    I would have RAID-5'd them instead, but that's me.

    I've had too many HD failures over the years to trust my computing experience to four HDs at once with no fault tolerance.

    i found QD32 the samsung 830's in raid-10 were about 50-100x faster than 15K SAS 3.5" 600gb dual ported drives. fastpath enabled. low queue depth,the 830's kind of suck but what's the point of low queue depth and raid.
