    Thumbs up VelociRaptor 10k Hard Drives for a sever !

    Is going with the VelociRaptor 10k Hard Drive really such a bad idea for a dedicated server with VM's and on RAID (maximum 4 disk on raid10 or raid50 probably..

    Apparently it is much less expensive than the other enterprise-grade 15k and even 10k drives of which their prices are outrageous in my opinion !

    Anyone out there using those hard drives on a dedicated server ??

    The VelociRaptor WD1000DHTZ have proven themselves well for us, we have lots of vps providers using them in RAID 10.

    Thank you very much
    with that has been said I guess they are a good option for dedicated servers for hosting companies, please anyone correct me if am wrong, suggestions are welcomed,,

    The Velociraptor series of drives are actually labeled "Enterprise" and do include the TLER flag for proper handling in RAID configurations. The only tiny disadvantage would simply be the difference in performance between SAS and SATA, which should be quite minimal.

    I don't see any reason not to use them.

    Thank you for confirming my theory !

    TO be honest I have assembled a server recently with 7x 7.2k rpm SATA3 Drives (Enterprise Value Grade) they are on RAID50 and am monitoring the disk queue length all the time and the performance is just great !

    I decided to go with the SATA3 model over SAS due to reduced cost + SATA3 got more cache !

    Maybe my comment will find someone confused about the difference between SATA3 and SAS and unsure which one to go with !,,

    thanks again,,

    Check with WD because I believe TLER isn't available on the very latest drives, at least that's the official answer I got their support dept recently.

    It's the same story with newer firmware on WD Blue and Balck series where it used to be possible to fettle with TLER settings.

    I have been using VelociRaptors in servers for many years. Raid 0/1/5/10, never an issue and great performance.

    For $230/TB, I honestly don't see how these are worth the slight performance increase over standard 7k RPM drives. I'm quite certain that either adding more drives to an array (so that data is spread out among more drives and you would therefore get faster reads) or using SSD's (depending on what type of data you're storing) would have a higher cost/performance ratio.

    You can get 1TB SSD's for around $500 now.

    10k is a significant speed advantage over 7k. I just spent around $175 a piece for HP 300GB 10k SAS drives. Velociraptors are a great value as long as your server will work with them.

    Sure you can get 1TB SSD, but is it worth the cost for the use case? These raptors are quite a bit faster. Not just slightly.

    You might not be able to add more drives to the array. You could be limited by the number of drive bays and rack units. Increasing these things could all mean higher costs.

    If you consider 40Mbps significant.. sure. http://www.storagereview.com/images/...altransfer.png

    The Seagate XT is $222 for 3TB at 165Mbps. A Raptor is $230 for 1TB at 205Mbps.

    Edit: That image is just the sequential transfer speed. The random is a lot slower for the XT, but still... price/storage/performance ratio is still pretty crappy for the Raptor.

    Considering you have database in your signature, I'd hope you'd see that sequentials are but a minor part of most workloads. 40mb/s is also about a 25% speed increase. This is a minor increase?

    It also uses less power on load. It all adds up.

    This.

    For hosting now I personally don't see anything but SSD as acceptable (except for big data/redundancy) the IOps alone justify the price for me. 10km is still great for a file server but it's now clear that SSD is the way forward for databases. Maybe not long til any HDD is deemed low end.

    Ever heard of seek time? What about iops?
    The raptor beats the pants off a 7200 rpm drive.
    Sequential/Random write/read speed is one thing.. but seek time and iops are pretty damn important too.
    The write latency on the XT is pathetic.

    Its pretty clear you haven't used a 1TB raptor. The XT is in no way a good comparison.

    We've been using 10K drives for minecraft hosting for almost 3 years on many of our nodes without issue. However there is a noticeable difference in game as well.

    Out of about 10 drives we've had one failure. We're hoping to get them for our VPS nodes soon.
