That means it take nearly 3 times as long as a top performing USB-C SSD to backup or do data integrity validation. Sustained speeds are decent but far below the claimed read speeds, a steady ~367 MB/sec.

But I often download and backup photo shoots exceeding that size. Some users might never write 60GB of data at a time after initially loading up the drive. And after a while, speed becomes erratic, oscillating from a pathetic ~81MB/sec to poor 189MB/sec. Tested using the fill-volume command of diglloydTools DiskTester.Īfter the first ~60GB of write activity, performance drops off a cliff from ~1000MB/sec down to ~189 MB/sec. But not for usage where a lot of sustained reading and writing is done. This makes it perfectly fine for many uses. As the I/O is intermittent and of modest amounts, the faster flash soaks it up, and it does indeed run up to over 1000 MB/sec. Samsung uses a dual-speed flash memory in the T7, the first layer having top speed, but the 2nd tier running far more slowly. Whether it is data integrity validation or backups from or to the T7, the T7 just does not deliver the performance I demand. Especially if I’ve hiked all day making images and just want to eat and sleep. Why it matters to meīut my usage involves often writing 30/50/100GB of of data at a time (raw camera files, large git repositories, etc), so an SSD must maintain consistently high performance or I get grumpy as a postal worker near XMAS. Under sustained writing, the Samsung T7 speed falls off a cliff.Īnd even worse, sustained read speeds are mediocre. That is, the Samsung T7 can deliver speeds slightly exceeding 1000 MB/sec for reads and writes. Problematic performance under sustained usageĪccording to the specifications, the T7 ought to be another big winner “up to” 1000/1050 MB/sec for writes/reads.

The Samsung T7 comes with both USB-A and USB-C cables, so it’s plug and play with a Mac or PC. See that review for details and background which apply to both the T5 and T7. Great performance, and prices came way down by 2020-an excellent value.

MPG reviewed the Samsung T5 back in 2017 and found a lot to like. MPG reviews it here in early 2021, when it is nicely discounted in price. The Samsung T7 arrived around April 2020.
