    My current setup has 2 x 3TB USB 3.0 HDD connected to Macmini for external storage and one 3TB external USB 3.0 drive for TM. I'm moving to either iMac 27" or nMP Hex core. I want to know what are reliable external thunderbolt storage options ? I would prefer external enclosure if that helps with swapping out drives as needed.

    Here's decent reviews of some options.

    I only have one on my 2012 MBP, it's a Lacie 1TB "rugged" portable, so its
    a 2.5 inch drive.
    Works really well and is pretty impressive speed wise.

    Hope that helps some ?

    I have a Mac Mini with internal ssd and use the OWC Mercury Elite Pro Dual (TB) for my primary external storage, running in RAID 0.

    http://eshop.macsales.com/item/OWC/METB7DH4.0T/

    I would caution against the G-Tech G-RAID in that article. I have had a G-Drive for several years with no complaint except for the long spin-up time, so I ordered a G-RAID to match but it arrived DOA; research showed that may other people are complaining of the same thing with recent G-Tech drives.

    have you ever run Blackmagic disk speed test on that OWC drive? i'd love to see those numbers vs what I am seeing on my nMP with various drives. I have the Qx2 [albeit eSata to TB] and i also have a Seagate 3TB drive in a Seagate Thunderbolt drive and I am getting USB 3 numbers from the Thunderbolt drive, basically the same, around 120 MB/s. Essentially, what i am finding, is the drive mechanics are impacting TB benefit, normalizing the field so to speak.

    Disk speed

    I am using a Pegasus r4 with 4 3TB drives in RAID0 and I am getting
    Write 722.8 Read 652.0

    BlackMagic shows about 350 in raid 0 with 2 7200 rpm disks which is about whau I'd expect. I have a CalDigit T3 coming Friday and it should do about 500 w/3disks.

    Interesting, when I check my Lacie external TB drive, I get less than 100MB/s!!

    NOT a great performance from a £200 drive :0(

    It might have a TB socket but the internals are not stacking up, seems like
    it's not even 7200rpm !!

    Don't quote me on this but I think a single 1TB 7200rpm drive is around 140MB/s with nothing on it. The more it fills up the slower it will get as it starts to use the outer platers. My first gen core i7 gaming PC with its internal SATA platter drive is around 110 MB/s.

    So it's not that bad a score is it?

    SSD and PCI-e SSD speeds are quicker and even more so when they are raided for performance reaching scores above and beyond 800+ MB/s

    that's a great score. I can't get over 120 with my Seagate desktop drive connected to a Seagate Thunderbolt adapter. I can understand my Qx2 from OWC as it's connected to an eSata hub then to thunderbolt, so that's limited to the eSata speeds, but i was hoping the drive on the TB adapter would be faster. I just changed my Qx2 setup from Spanning to RAID0, so that should give me more performance.

    Sorry to say it but a single he'd is never going to give more than 120-180 no matter the interface since the he'd is the limiting factor. And the QX2 according to reviews is about the same speed at any setting, it is just slow.

    A lot depends on how much you want to spend. If you want to be able to mix and match drives an enclosure like the drobo 5d would be good. However it is still TB1 and is slow compared to a Pegasus2. If you already have 4 of the same drive to use something like the Pegasus2 R4 w/out any drives is a good option. It is TB2 and just about the fastest enclosure of this type out there. I personally have a r6 12TB sitting on my desk waiting for my nMP.

    You'll want to fire up Disk Utility to discover what drive or drives you have inside and how they might be configured.

    If RAID-1, it could be slow with some 5400rpm drives inside a Little Big Disk.

    one can use different drives in the r4; it supports independent drive access and/or software RAIDs.

    Yes you are correct, I was to brief in my comment. If you want to run say a RAID 5 all the drives need to be the same size. From what I understand there is also a significant hit to speed when you mix drives, but that may just be apocryphal.

    i don't think this is true: i think one CAN mix drives (it can be inadvisable for a number of reasons) in a RAID set, but an amount of space equal to the smallest drive's size will be applied to all drives in the set.

    yes, but that would just be silly to do now wouldn't it.

    our first post implied that other enclosures might not be able to use drives of different sizes, then you followed up by saying RAID5 requires it.

    neither statement was correct so just wanted to make sure someone else reading this wasn't confused by them.

    don't mean to be picky -- just trying to be precise here as we compare enclosures. TB enclosures are an interesting topic to me lately and i've compared a few.

    No Raid, simple 2.5 external TB enclosure.

    Found out that it's 5400rpm :0( pretty bummed out about that !!
    It didn't say in the included "blurb" so with 10GBS transfer rates all over the
    box, you assume it's not a bloody 5400 speed plain 'ole drive ..ggrrr....

    I assume they went for the 5400 RPM drive as it will use less power and thus favourable for laptops.

    Yup, good point - there is no option for a PSU on this, just TB & USB3
    connections.

    Oh well, it works OK and seems to stream sample data and copy fairly
    quickly.

    I assume you have a LaCie Rugged drive with Thunderbolt and USB 3.0

    Your speed is limited by the hard drive mechanism.

    Same model with SSD inside is 3x or more faster.

    A 7200 RPM drive might get you 110-120MB/sec, so not that much faster.

    Thunderbolt RAID on MAC and Windows

    That is scary :) Back up my friend!

    I have the tRAID-T2
    http://www.datoptic.com/ec/dual-thunderbolt-raid-with-5x-sata-bay-for-mac-and-windows.html

    about 2 months, their page update with FW/eSATA/USB3.0 connections.

    Talk to the tech and get the parts to update to my tRAID-T2

    One thing i like it lots more than other is upgrade-able.

    After 30 min UPS delivered, my tRAID-T2 has Thunderbolt, eSATA, USB3.0 and FireWire800...

    I formated 16TB RAID5 as NTFS, and used Tuxera NTFS http://www.tuxera.com/products/tuxera-ntfs-for-mac/

    My tRAID now can be use between Window and MAC, even with Thunderbolt connection in both OS, where other thunderbolt device refuses to work on Windows

    I dont believe, there is other offers this much of interfaces and ability to upgrade
