Samsung Portable SSD T7 1TB review

The T7 1TB is a pocket-sized external SSD from Samsung. It connects over USB-C at USB 3.2 Gen 2 (10Gbps). It does not use Gen 2x2 or USB4, so Samsung's quoted 1,050MB/s read and 1,000MB/s write are the ceiling. Owners praise it for fast transfers of large files, for its small size and light weight, and for plug-and-play setup. That combination suits anyone who carries big files between machines and wants a drive that slips into a bag.

Samsung quotes up to 1,050MB/s sequential read and up to 1,000MB/s sequential write. Those are maximums. Samsung notes that the stated speeds need a host supporting USB 3.2 Gen 2 and UASP mode, so a port or enclosure path that lacks either may not reach them.

Owner reports add a caveat on writes. Sustained writes slow down once a large transfer exceeds the TurboWrite cache. If you copy very large batches in a single run, such as full project folders or big video libraries, expect the speed to drop part-way through. Because the interface is Gen 2 rather than Gen 2x2 or USB4, there is no faster mode to move up to on a newer host.

The casing is a solid aluminium unibody. Samsung gives drop resistance of up to 2 metres, based on an internal free-fall test. It also states that there is no IP rating, so the drive has no listed protection against dust or water. With a drop figure but no ingress rating, it suits a laptop bag or a desk better than a dusty or wet site.

One detail is unresolved. Samsung's UK page gives a skin temperature limit of 51ºC, while other Samsung regional pages give 45ºC. If you plan to use the drive somewhere warm, the lower figure is the safer one to work to.

The T7 offers AES 256-bit hardware encryption with password protection. That is useful if you carry client files, work documents or personal data and want a password between a lost drive and its contents. The encryption is done in hardware, which is what Samsung lists.

Samsung Magician software runs on Windows, macOS and Android only. Samsung doesn't mention Linux for it. If you work mainly on Linux, check how you would manage the drive before you rely on its security features.

The drive has a USB-C interface and is described by owners as plug and play. Samsung's Magician software covers Windows, macOS and Android. Linux is not mentioned by Samsung.

Samsung's Canadian and Singapore pages say some operating systems may require reformatting the T7. The research doesn't say which systems are affected. If you plan to share the drive between, say, a Mac and a Windows PC, check before you rely on it working with no preparation. Check the host's ports and operating system before buying, and be ready to reformat the drive if needed.

Samsung gives a limited 3-year warranty. That is the cover on offer, and Samsung lists nothing longer for this model.

The T7 1TB suits people who want a small aluminium drive with hardware encryption and fast transfers of large files. It fits Windows, macOS and Android users best, because those are the systems Samsung's software supports. It is less suited to those who write huge batches in one go, given the owner reports of slower sustained writes. It is also less suited to Linux users, to anyone who needs a dust or water rating, and to anyone who wants speeds beyond USB 3.2 Gen 2.
