    We are thinking about buying an external drive to help out with our video editing needs.

    We use Premiere CS6, AE, 3d work in Element, and some basic color Grading stuff.

    We have two main computers that would need access to the external drives
    The first is a mid 2012 Mac pro 6 core 3.33 with an ssd
    The second is a 2014 Mac pro 4 core 3.7

    Right now we have a Mycloud 4tb, but I feel like it is slowing down our workflow.

    What would be our best options?

    Are these computers networked? Wifi or cabled?

    Buy a HD with two disks (RAID) and a fast connection (Thunderbolt or USB3) and hook it up to your Mac. You can share the drive so that the other computers in your local network can use it too (albeit slower).

    What do you think about the Velociraptor? http://www.amazon.com/VelociRaptor-External-Drive-Storage-Thunderbolt/dp/B008R7EWF2

    It looks like it dropped a ton in price...

    We have a GigSwitch we are using right now to connect to the MyCloud

    It's very fast but also pretty expensive.
    An overview of various RAID box speeds is at the end of this review:
    http://www.cnet.com/products/wd-my-book-velociraptor-duo/2/
    I personally would select a cheaper RAID.

    (When using a networked solution, the maximum transferspeed over gigabit will be limited to 100MB/s.)

    We would probably just hook up our two macs with thunderbolt 1 to the external drive.

    We found a veloci for 299$ down from almost $700 and the other drives on that site seem more expensive. The Duo has 4TB but it costs about $450

    Which of the two is faster?
    If we are working from two computers using these drives, will there be a problem?

    Thankyou!

    If you have a Thunderbolt drive, you can only hook it up to one Mac directly. If you share that drive, it can be accessed from the other computer too, via the network.

    If its connected to the macpro cyl2013 through TB and the macpro 2011 acceses it through the network, will the speed be much slower for the 2011?

    Via gigabit the maximum datarate will be limited to 100 MB/s. The WD Duo RAID 0 (normal version) was rated at 168 MB/s in the linked CNET review. So yes, it will be slower via the network. But it may still be quite workable depending on what you're using the storage for.

    Pretty much any standard 4 or 6TB drive is capable of those speeds though. A pair of two 10K WD VelociRaptors in RAID0 would be much higher. So must be the interface that was tested and not the drives.

    At one time WD 10K VRs were offered as a way to have 2TB of "near-SSD" performance closer to 380MB/sec.

    CNet information:
    2011 MacBook Pro running OS X Lion, on a SATA 3 (6Gbps) SSD, as the test machine. In the first set of testing, when moving data from a daisy-chained Pegasus R6, the My Book VelociRaptor Duo showed its top performance and scored 363MBps,

    PCMag:
    The VelociRaptor Duo speeds along with a 374 MBps read speed and 343 MBps write speed

    Sure.
    The 168MB/s refers to the standard version of the WD Duo (see the bars at the bottom of the article), not the 10k version that was subject of the review.

    Actually, 110 to 115 MB/s is easily reached, even without jumbo frames.

    I just copied a GB file from my home server to my workstation over GbE, and the copy reported:

    Speed : 111,037,086 Bytes/sec.​

    Well, is that great.

    The message for the TS was: access via gigabit to this RAID system will be slower than directly via Thunderbolt or USB3.

    The message also included a false statement about the speed limit on GbE - citing an arbitrary number of MB/sec.
