    they are available but the thunderbolt are around 3 times the price as usb 3 with around 2x the read and write speeds.

    With something like that, why not just get a NAS? I assume the Pegasus only works over TB?

    Having read the review, yeah the numbers are great, and it would be nice to hook upto a pimped Mac Pro, but attached to an MBP or Imac, the bottleneck is going to be the CPU/GPU in the machines. Still at loss to why there is no TB on Mac pros...

    May I also recommend Hitachi's "G-Technology" brand of drives. If you mean good by suitable for professional use, its price is a little hefty but worth every penny!

    Single drive, or RAID setup?

    Because if you talking about a single 1TB mechanical hard drive, you're wasting your money. Thunderbolt is WAY overkill.

    With a large 6G SSD, it's worth looking into.

    If the drive is a traditional HD even running at 7200RPM, is there any advantage of having TB vs USB3? I would be using the drive to house my RAW files for LR to access. I guess I need to know if a 7200RPM drive can saturate the USB3 pipeline therefore giving a TB connection the advantage. Somehow I think you would need an SSD before TB becomes useful.

    I have some Seagate GoFlex drives that can be converted to Thunderbolt with the adaptor but don't know if it is even worth it. I think the drives I have are only 5400RPM.

    Not at all. Unless the external is an SSD there is absolutely zero reason to spring for Thunderbolt. Well, I suppose a Raid 0 array might be worth it, but even then I'd go with USB 3.

    Hell, 7200rpm drives would probably max out with FireWire 800. :p

    So no reason to get TB for a regular spinning 2.5 drive? Should just go with FW800? Right now I have external 3.5 connected via usb 2.0 on iMac, wanted a bus powered 2.5 to use as primary HD for my pictures and music, about 400 gigs or so...sounds like I would only benefit from TB if instead I went with a SSD drive? Anyone tried the go flex TB with a OWC SSD?

    Yeah, go USB3 if your Mac supports it, but if not FW800 is the way to go. USB will is still a good deal faster than FW800, but if you don't have a 2012 model Mac then FW800 will still get the job done nicely. Thunderbolt is just a waste of bandwidth when used with a mechanical hard drive. The thing simply cannot spin fast enough to fill the Thunderbolt pipe. USB3 is much cheaper and performs just as well.

    tl;dr - screw Thunderbolt and screw Intel

    yeah i want TB HDD drives as well. But not for 400...+

    I'm trying to find comparisons in terms of performance of TB vs USB 3.0. I would think the negating factor here is hard drive.

    so I don't see how the TB which is 2x the speed be that faster than 3.0 if you are dealing with HDD as your storage base.

    the fastest consumer drive according to fastestssd is 550MB/s read (240GB)
    520MB/s write (240GB).

    so. outside of overhead, the USB3.0 should achieve this speed (4.8Gbps/8).

    …When used with single spinning disks.

    Thunderbolt has its uses, for sure, in situations where USB3 isn’t enough, or where one needs to daisy chain multiple high-bandwidth components into a single port.
