    I have a MBP Mid 2009 model with this specs:

    I'm planning to do RAID 0 (2x SSDs). Anyone has the same model with me and already on RAID 0 with 2x SSDs?

    Would you mind sharing your write and read speed screenshots?

    Thanks.

    Which SATA revision is your optical bay? If SATA II, you should probably expect a little bit less than twice that bandwidth. 500-550 MB/sec area, I'd say.

    I just got a 2012 cMBP and was deciding whether to have one or two drives in my machine.

    I'd like to know as well!

    - So then you have SATA II in both bays. The speeds I mentioned should be about right.

    - That's a completely different matter. The 2012 model has stable SATA III connections in both bays. You should achieve close to 1 GB/sec sequential read and write with a current SSD.

    My 2012 MBP (El Capitan) has 2 240GB 850 Evo's using Apple's RAID0. Using the Blackmagic test, the read is pretty consistent around 965MB/s. The writes can vary quite a bit anywhere from below 500 to sometimes peaking in the 900's. The highest score at the end is in the mid 850's, most often mid-high 600's is what I get.

    If you're thinking of doing RAID0, be sure to read:
    http://www.tomshardware.com/reviews/ssd-raid-benchmark,3485.html

    I mentioned in another post that RAID0 helps a lot in one particular application I have (editing in a DVR program). Other than that, I wouldn't be able to tell the difference between RAID0 or not. I thought there could be a major difference in some database processing that I do but that wasn't the case (but I didn't try to do any database tuning). No regrets here, though - the performance increase in that one application is enough for me to keep it as RAID0.

    MacInTO, in another thread you mentioned you use a Corsair SSD. Which computer do you use it in?

    I use it in a 2011 13" i7 2.8 MBP. It's my media server. I don't need super fast speeds, but this is a good drive for the price.

    Thanks for the info. We're trying to see if the Corsairs with Phison controllers work in the the pre-2011 Macs. Nice to know that it works for you.

    I had a mid 2009 2.26 ghz mbp with only one ssd but if you're interested, I have read speeds of about 260 mb/sec and write of 180 mb/sec.
