Thunderbolt SSD Boot Speed Test

[police340]

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?

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

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
