    Hello,

    I have my iMac Core i7, 3.4GHz running off Lacie Thunderbolt SSD, I ran BlackMagic Speed Test to look at number which i am not too knowledgeable about. Do these numbers look good on attached image? Thanks, Bill

    In theory the SSD can reach 400-500 MB/s with 6Gbps, that's what I read.

    200-250 MB/s sequential read/write is still very good.

    What I would like to know is whether we can reach the SATA speeds ('internal drive) on the Thunderbolt cable. I think TB is up to 10 Gbps so it should work, but I have seen very little benchmarks that demonstrate it.

    For comparison see:

    The LaCie Thunderbolt Little Big Disk maxes out around 400-480MBps when you swap out the drives for faster SATA SSDs and run them in RAID 0. The LaCie uses a single channel SATA III 6.0Gbps controller and splits it with a daughter board. The Seagate Thunderbolt GoFlex 2.5" adapter also uses a similar Marvell based controller and gets much better single drive performance, which can match or better the LaCie in RAID 0.

    Can you get 400+ MB/s sequential read on a single external SSD (not RAID) with USB3.0 or Thunderbolt?

    SSD Thunderbolt Speed Test

    Thanks for the responses all. I have the Thunderbolt with 480Gb OWC Mercury Electra and OCZ 240 Gb Vertex. I have another OCZ 240Gb that I could use in my second Lacie drive or should just use the two hard drives that came with it. Thanks for all the help. Bill

    Thunderbolt SSD Boot Drive SSD Speed test

    Hello,

    I am not sure how to check that by itself. As you see Ive used BlackMagic. Do you have any recommendations on how to do it. I am going to try to set up the second Lacie drive tonight with the two OCZ 240 Gb drives and the OWC 480Gb and run them as Raid 0 to see how that goes.

    Thanks,
    Bill
