    I currently has a LaCie 2big 4tb raid. I'm planning to change the HDD for 2 SSDs for faster raid 0 storage. I'll be using it as a working drive for photography purposes. The thing I don't know is if the drive accepts SSDs and even more if it's support faster writing speeds.

    Anyone tried before?

    Thanks!

    I had a 2big TB 6TB RAID (that I ended up giving to a friend), but never tried putting SSDs into it. They take 3.5 inch drives, so to use SSDs, you'd need
    something like this:

    Personally, I would question whether an interface (Thunderbolt-SATA bridge) designed for relatively slow hard drives will deliver faster speeds that SSDs offer...

    Yes, that what I thought. I bought the converter already, as soon it arrives I'll test it, if doesn't work I'll bought the OCW mercury elite pro dual, which accept faster speeds.

    The LaCie 2big Thunderbolt is limited to 3Gb/s per SATA channel. It wouldn't fully utilize the speed of an SSD in terms of maximum transfer rate but the seek time and random read should be excellent.

    The 2.5" drive will require an adapter like the ADPTADRV listed above as you must have the same connector positioning as a 3.5" drive.

    I own an OWC Mercury Elite Pro Dual, and while it is good with regular hard drives, it is definitely NOT for use with dual SSDs (the site quotes a max speed of 442MB/sec) which is 60MB/sec faster than a single SSD in a USB3 (Mercury On The Pro USB3 enclosure)...

    ----------

    Based on some mental arithmetic, that should mean that with the two SSDs in RAID0 (OS X software RAID) he should be able to achieve about 750MB/sec, no?

    Hard to say with any certainty without actually testing it out but I would expect about 500MB/s to be more likely.

    Hi guys! I contacted OWC support and they confirm me it supports SSDs and the high speed they can operate in SATA, so it can do it. I'll be buying it soon and test it.

    Well, i'd like to know what idiot at OWC told you that they operate at high speed, because their own site shows they don't.

    As an example of what you can get, speed wise:

    http://smile.amazon.com/Akitio-Neutrino-Thunder-Duo-Enclosure/dp/B00D4EBIV4/

    I used to have two of these in use, but I replaced them with a Thunderbay 4 mini, which is a far better unit.

    What happened to the LaCie, didn't it work?

    No it won't. Its Thunderbolt 1. Did you read the specs on the link you posted?

    I think he means it supports faster speeds than the OWC Mercury Elite Pro Dual, which it does.

    Yes, I know it's thundrbolt. I bought and archives almost 800mbs with both SSDs. I actually sold it since the iMac do the same with any mess on the desk.
