You can password-protect it with full 256-bit AES encryption, which is now optional, and not full-time as with the T1 (which again, may account for its faster times with files and folders). The T3 is also enterprise/security friendly. But still… where’s the SuperSpeed+? Not just fast Fast enough that it doesn’t look completely mismatched against the Samsung 850 EVO or Kingston HyperX Savage, internal SATA 6Gbps drives in the chart above. Its large-file copy times were nearly the same as the T1, but thanks either to the improved controller or the disabled encryption, it hacked quite a few seconds off the T1’s time with our 20GB batch of files and folders. Where the T3 seems greatly improved is in its handling of large batches of smaller files. The T3 proved quite a bit faster than the T1 with our 20GB set of files and folders. The numbers below reflect NTFS performance.ĪS SSD rated the T3 as only marginally faster than the T1, but check out the copy times for files and folders below. Though not shown, on a non-UASP USB 3.0 port, transfers were almost exactly 300MBps each way. Seagate Game Drive 500GB USB SSD (120) SSK USB NVME enclosure (24) with a 256GB Samsung NVME SSD I had this NVME drive lying around after replacing it in a laptop, so I don’t know how much it. In out tests, the T3 didn’t reach its theoretical maximums (few drives do), but it was darn close, as you can see in the charts below.

By the way, UASP stands for “USB attached SCSI Protocol.” If you spell it all out, you get “Universal Serial Bus attached Small Computer System Interface.” I’ll stick with UASP. On a normal USB 3.x bus that will dip to around 350MBps (ironic sigh), and, of course, drop all the way down to around 50MBps via USB 2.0. If the T3 is attached to a USB port that features UASP then you can theoretically see up to 450MBps each way. Go there for details on competing products and how we tested them. This review is part of our roundup of best external drives.

Full-time encryption or no, the T1 and T3 are the only drives I’m aware of that take full advantage of Gen 1 SuperSpeed USB, though that also depends on what grade of USB port you attach it to. However, the speed improvements may be due to the now-optional encryption that we left turned off. The T3 is based on Samsung’s TLC NAND and uses a more refined version of the MGX controller found in the T1. OK, I’m back now, so I can tell you that aside from feeling more expensive than the T1 (which it’s not), the T3 is an even better performer, especially with smaller files and folders. The fact these numbers line up would indicate to me that both our results are in fact capped by the drives in use, not the bandwidth provided by USB3.The T3 has a USB Type-C connector and comes with a non-captive Type-C-to-USB-3.x-Type-A cable. I'd expect these to operate at about 1.5-1.7 times better than the drive you describe, which is what I got as well. If not, then there may be other issues coming into play.ĮDIT: Using HD Tune I did a benchmark of my own USB3 drive, which is a caddy providing a RAID1 of two SATA2 5900rpm drives. If it's getting the same sort of performance, then see my first paragraph. The best test would be to connect the drive internally and test it there. 25-30MB/s doesn't sound overly low to me. You won't get anywhere near that with a 5200rpm drive though unfortunately. In my experience with my own drive, I've noticed this to be true.Īs for exact speeds, SATA 2 operates at 3 Gb/s optimally, which gives a maximum bandwidth of ~384MB/s. USB3 operates at higher speeds than SATA can handle, so optimally you should notice no difference between USB3 and an internal drive of the same type.
