    I had 2x OWC 480 6G SSDs set to RAID0 on a Sonnet Tempo Pro installed in slot 2 which have seemingly failed after over 1 years use.

    No one has ever heard of this happening before so if this is the best solution i'll go back to it.

    Slot 1: ATI HD 5870 (which i want to replace with something CUDA based, probably a GTX 680)
    Slot 2: <free>
    Slot 3: Velocity Solo x2 w OWC 480 6G SSD (OSX Mavericks boot)
    Slot 4: Orico PFU3-2P USB3.0

    I'm only getting 220MB/s write and 350MB/s read on my single OWC 6G through black magic speed test. Why is this so low?

    I never got much more than 600MB/s read from the RAID 0 OWC drives on the Sonnet board anyway.

    So where to go now then? 2x 480GB OWC 6G's again or do i get 2x Angelbird 512s or maybe 2x Samsung 850 Pro's?

    Is the Sonnet Tempo Pro the best card to go with? I've read the Velocity Duo x2 is a fair bit slower and i may have trouble fitting it in with all those cards around it.

    Anything else out there now that's a better buy? Drive doesn't need to be bootable, its basically scratch disc and temporary storage.

    Concerning OWC SSD Products you may be interested in this thread:


    My Experience with OWC SSDs in an MBA was not good, it failed in a weeks time.

    I have all my slots filled, two (slots 2 and 3) with Velocity Duo x2s. All my SSDs are Samsung, IMHO, the most reliable brand. None of them are set in a Raid however.

    Here is a test I ran with a pair of 256GB Samsung 840 Pro SSDs in RAID-0 on the Sonnet Tempo Pro (the 850 Pro may be faster still). It was my boot drive prior to changing to a Apple PCI SSD.

    You may seriously consider the Apple SSD + PCIe adaptor. Native TRIM, high speed.

    I wasn't aware you could buy an Apple SSD. Is that the one from a nMP?

    I have to get my replacements from the same supplier so this Apple SSD seems s bit of a long shot considering the fast one is gold dust.

    Think I'll stick with the Sonnet Tempo Pro. What about SSDs. OWC, Samsung 850 or Angelbird. Is it worth getting Angelbird for the native TRIM support?

    ^^^^You know what I think of OWC from my thread above. I have 840 series Samsung, and as I said, I believe the are the most reliable, I know of no one on this forum who has tried Anglebird. I'd luv to hear some feedback on them.

    I'd love to have the real trim support, but man they think highly of their little hack - $600 for the 1tb angelbird SSD.

    I run 840 EVOs myself (and one 840 Pro) and have had good luck with them as well.

    I concur with h9826790. I just purchased from ebay a 1TB Apple SSD after having considered the Sonnet Tempo Pro Plus with two 850 EVO in RAID0.

    If you were to replace the OWC drives get Samsung 850 EVO, they come with a 5 year warranty.

    This is an excellent article on how to restore your SSD drive performance.

    How to restore your SSD to peak performance

    Essentially if you have not been running TRIM on your drives then back up your data and performa low level/ secure erase of your drive.

    I had a 840 EVO, updated the firmware after experiencing performance loss due to drift within the SSD cells. Even after the firmware update performance had improved minimally until I securely erased the drive with the magician software.

    I do not think OWC has any tools so the one in the article for Linux and Windows ought to work too.

    Remember: Backup BACKUP BACKUP!

    Another option, if you have a spare open slot, is using 2 x Apricorn Velocity Solo x2 cards, each with one (or two) SSD's.

    The advantage of this is lower cost, and faster performance. The Sonnet card maxes out at 960MB/s using two SSD's on the single card. Two Samsung EVO's can surpass that limit.

    The Apricorn Velocity Solo x2 supports 550 MB/s PER CARD with one SSD or 800MB/s with 2 SSD's per card. Using two cards in RAID 0, you can attain 1100MB/s with 2 SSD's or (theoretically) 1600MB/s using a set of 4 SSD's.

    The Apricorn cards are about $90 each, compared to >$250US for the Sonnet.

    Again, it takes an extra slot, but I've been using a pair of x2's for a few months, and no issues at all and my benchmarks are well into the 900MB/s read speed using Blackmagic.

    Something to consider. :)
