    Hi everyone,

    [I'll be walking through what I've done thus far, so you can skip to the end for what I'm actually asking]

    I have Blackmagic UltraStudio 3D ( http://www.blackmagicdesign.com/products/ultrastudio3d/ ) that I would like to use to record some uncompressed 1080p59.94 video. However, after trying several different products only to come up short every time, I'm desperate to find a solution (I really probably should've asked first, but being somewhat tech savvy, I thought I could do it myself.. oh well).

    So first off, I have a late 2011 15-inch MBP (I upgraded it with 16GB of RAM and an Intel 520 Series 480GB SSD) that I tried to do this with, but I could only achieve a read/write speed of ~500/290 MBps. I also have some OCZ Vertex 4 512GB SSDs ( http://www.ocztechnology.com/ocz-vertex-4-sata-iii-2-5-ssd.html#specifications ) at my disposal, so I thought that maybe I could use some kind of Thunderbolt device to achieve higher read/write speeds.

    I made the big mistake of picking up the Drobo Mini, which has Thunderbolt support. Just to really make sure I have the power necessary, I also picked up a Crucial m4 256GB mSATA SSD, so that this thing would be beefed up. However, after getting everything setup and ready, the Drobo Mini benchmarked at a miserable ~300/230 MBps, worse than my internal drive! After doing more research on Drobo (blogs, reviews and http://www.drobo.com/how-it-works/performance-professional.php ), I've decided to give up on Drobo and go elsewhere.

    I was looking into other RAID arrays, such as LaCie 2big (and other ones I found here: https://thunderbolttechnology.net/products?tid=1&field_company_nid=All ), but I'm pretty discouraged at this point and would sincerely appreciate a nudge in the right direction from someone who actually knows what they're doing. =P

    Long story short, are there any Thunderbolt devices out there that I can pop in my SSDs to achieve the advertised 560/510 MBps read/write speeds? Or if not using my drives, something that will allow me to get very fast read/write speeds?

    Thanks and Happy Thanksgiving!

    You definitely need faster speed internally.

    I have the LaCie 2Big 4TB as RAID 0 Thunderbolt. It's pretty fast, almost as fast as the SSD in my MBPr. LaCie uses 7200rpm Segate Baracudda drives in the 2Big. You might be able to replace the Segates with a SSD. They have a new Thunderbolt SSD out now which should be really fast, might want take a look at LaCie's website.

    Thanks nuckinfutz, but I'm still going to need faster speeds than that.

    Thanks mawyatt; their new Thunderbolt SSD also doesn't go as fast enough as I would hope. Do you think it would be challenging to to replace the Seagate drives in the 2big?

    Hey Guys

    I own a bit of thunderbolt kit, and have found that once you leave the consumer threshold of speed about 200mB/s, prices are not proportional to performance.

    i have
    2big disk 220mB/s
    little big disk 200MB/s

    little big disk modded with 2 128gb ssds 400MB/s read writes
    these drives are rated at 550mB/s but the enclosure can only handle sata 2, so the speeds i got where very limited but better than using the seagate thunder bolt adapter and i am able to use 2 drives

    the seagate thunderbolt portable cant handle 512gb drives
    the home version is powered so it can run but again these run at sata 2 solutions are not for recoding media

    pegasus r4 450MB/s raid 5 (never tried raid 0 but mgf claims 500MB/s)
    so this will barely work unless you swapp the drives for ssd and then you have over 800 MB/s. I have not needed this since i shoot dslr but its an option in the future for me.

    According to aja data calculator you need 497.5MB/s for 10bitRGB 1080p 60fps. the consumer products you mentioned before are not practical as you would need to daisy chain 3 2big disk in raid 0 for the required speed and bit of overhead. This type of solution offers no protection and is silly in my opinion.

    I would recommend you test the pegasus r6 for your needs


    in 2nd Place
    the new Sata 3 Little bigdisk have really improved with 635MB/s and the price is alot better than the original 240gb which was $800 (wow). the new ones are 1000 for a TB but i dont think that will be enough storage for you needs but it will capture.

    What camera are you using?

    Thanks faxoli-- I'm actually not using a camera. I use my Blackmagic Ultrastudio 3D to record video through an HDMI input. I'm currently looking at the Pegasus drive, but the SSD LaCie Little Big Disk looks amazing (I'm assuming the drives inside aren't hot swappable?).

    Thanks doubletap and faxoli, but I'm afraid we're moving out of my price range. =[[
