Samsung T7 Touch SSD – a very fast, secure external backup
4.8Overall Score
Name: Samsung T7 Touch external SSD
Price (RRP): $from 279
Manufacturer: Samsung

The Samsung T7 Touch has two unique selling features. A touch button for fingerprint security and the latest USB-C 3.2 Gen 2 (10Gbps) interface that can reach 1Gbps data transfer speeds.

The Samsung T7 Touch does in one second what takes between six and ten times longer on a traditional external SATA6 USB interface SSD. But there is one catch – you need a USB-C 3.2 Gen 2 device to copy from or to.

Now before you get confused about the Samsung T7 Touch, its interface is backwards compatible with all USB. The existing USB-C 3.1 Gen 1 and 2 have been thoughtfully renamed by the USB-IF as USB-C 3.2 Gen 1 and 2 for 5Gbps and 10Gbps respectively. And the drive is backwards compatible with USB-A 2.0 and 3.0!

Tests

Unfortunately, we don’t have any native USB-C 3.2 Gen 2 computers at present. Our test Lenovo 2019 Yoga C930 has 2 x Thunderbolt 3 (that should be Gen 2 compatible) and 1 x USB-A 3.1 Gen 1.

So, our tests reflect that setup.

The Samsung T7 achieves 857/769MB/s using a Thunderbolt 3 port – that’s not far off the claimed speeds, and we expect the 500GB to perform a little slower than 1 or 2GB with larger caches.

USB-C over Thunderbolt

On a using a Gen 1 port it achieves 439/437MB/s which is at the limit of that port.

But interestingly both ports had very similar large file transfer rates – within a few percent of each other indicating that there is a small cache buffering the flash storage. If you transfer a lot of large files, then you may need to look at competing products with larger caches.

Obviously, it works on Thunderbolt 3 (20Gbps) at close to Gen 2 speeds.

Let’s dig deeper

The Samsung T7 touch uses 3-bit 92L TLC V-NAND, and its cache is called TurboWrite Technology. This is not really DRAM cache, but a small and fixed portion of the TLC is treated as 1-bit SLC.

That cache, one full with larger files, does slow down the transfer rates. Most typcial users will not notice it.

The App (tested Windows)

The Samsung Portable SSD software for Windows, Mac or Android allows for firmware updates and setting security levels – off, password, or password and fingerprint. The data is AES 256-bit hardware encrypted.

We were unable to discover any other functionality like backup or restore. Samsung’s response was “You can select files such as photos and mp3s that you want to back up through the file manager on your device, and copy/paste them to the PSSD.”
