So gonna need (I think) a new external hard drive for a new 27" iMc.
Currently I have an older LaCie 3 TB HDD. It has Fire wire 800 + USB 3 but no Thunderbolt.
What do folks recommend?
Thunderbolt is only better than usb3 if you have a drive that can transfer data faster than the port itself. No spinning disk, even a raid stripped one, will overrun the USB 3 port. Thunderbolt will shine with an external RAID striped SSD array!So from the comments so far it seems I may as well just roll with the drive I have. No?
The reason the one I have doesn't have Thunderbolt is because by 2009 iMac didn't have the capability. That's why I'm using the FireWire 800. But the new box will have USB 3 so, good to go I guess.
So are you saying that unless you're going SSD to SSD Thunderbolt really isn't going to make a noticeable difference over USB3?Thunderbolt is only better than usb3 if you have a drive that can transfer data faster than the port itself.

Exactly. If you are sticking with a HDD, jut keep the USB3 setup you have.So are you saying that unless you're going SSD to SSD Thunderbolt really isn't going to make a noticeable difference over USB3?
Thunderbolt is overkill for the speed at which an HDD can transfer data. USB 3 will be plenty fast for file storage, unless you're editing video files on the external.So from the comments so far it seems I may as well just roll with the drive I have. No?

It would be helpful to know what you plan to do with the hard drive.
If you want a backup/long term file storage, then speed doesn't matter much. For that purpose, the Seagate 8tb USB 3.0 drives ($250 on Amazon) are hard to beat. They're slow, but eight terabytes is hard to argue with. When I'm editing photos, I keep them on the internal drive for fast loading, and once I'm done with a shoot, I copy them to two of these external drives and delete them from the internal disk. (I don't believe in keeping anything I care about on just one drive; I've had too many drives fail in the past).
On the other hand, if you're going to be working off of the drive, such as editing video, then the best solution would be a RAID array running off of Thunderbolt, which will be super fast, but much more expensive.
USB 3 support up to 640 MBps (megabytes per second) and some of the fastest SSD drives are in the mid 500s read/write. RAID HDDs come in at about half that and non-RAID HDD half again read/write.So are you saying that unless you're going SSD to SSD Thunderbolt really isn't going to make a noticeable difference over USB3?

The OP was looking at single disk solutions.You won't find a USB3 enclosure that can deliver anywhere near 640MBps.
And I have 4 x 7200 RPM HDDs in RAID0 inside a Thunderbay IV enclosure, and that volume benchmarks at 720MB/sec. So you can benefit from Thunderbolt even with HDDs in RAID.
I also have 4 x Samsung 850 EVOs x 500GB in RAID0 inside a Thunderbay 4 mini enclosure, that baby flies
Avoid Seagate at all costs! Their failure rate for 3Tb drives is something above 20%. This has been my experience with them personally. Western Digital or, better yet, a Q-drive. Thunderbolt is faster but usually more expensive.
I'm surprised no one mentions OWC drives. I'm on my 4th one. Not one has failed. Going back~ 4years. I know they can be pricy..
