Samsung Portable SSD T5 review

Samsung Portable SSD T5 review

Last Updated on by Daniel Lawrence

In terms of portable storage, the Samsung Portable SSD T5 is top-of-the-line. A small external storage device can be as powerful as a power bank or as compact as a stack of credit cards.

Compared to similarly-sized solid-state storage devices such as Kingston’s DataTraveler Ultimate GT USB drive, the Samsung Portable SSD T5 is so small you could slip it into your shirt pocket without anyone noticing. Add to this its 10Gbps USB 3.1 Type-C Gen 2 interface, making it capable of delivering twice the theoretical transfer rate of its predecessors, and you have a device that packs a big punch.

It measures 74 x 57 x 10.5mm and weighs only 51g, making it small and lightweight enough to slip into even a tight front jeans pocket.

Aside from the Samsung logo on the front, the power LED, and the Type-C connector, it’s entirely metal (with a swish brushed finish).

The primary difference between it and the T3 is that it abandons the dual-tone color scheme.

It comes with an ASMedia mSATA-to-USB bridge controller instead of Samsung’s own and is available in capacities between 250GB and 2TB.

There is a major improvement in the 64-layer 3D V-NAND Triple Level Cell flash memory, as well as the updated firmware and the support for TRIM via the UASP (USB attached SCSI) protocol.

To improve performance when transferring small files, you may want to format the drive to NTFS instead of using the default exFAT file system.

Additionally, the drive is now officially compatible with Android devices and is specified as shock-resistant, capable of handling drops of up to 2m (albeit under controlled conditions).


Despite using a USB Type-C Gen 1 connector (limited to 5Gbps), the T5 drive achieved 433MBps and 323MBps in CrystalDiskMark, and up to 462Mbps and 323MBps under ATTO. Additionally, it transferred a 10GB file in 47 seconds using Teracopy, giving it a real-life transfer rate of just over 212MBps.

According to Samsung, you will achieve much faster read and write speeds with a USB Type-C Gen 2 connector, up to 540MBps and 515MBps respectively in read/write speeds.

The bundle includes USB Type-C to Type-C and Type-C to Type-A cables, as well as a 256-bit AES hardware encryption chip and software suite for Windows, macOS, and Android.

Pros Cons
Highly compact Expensive
Incredibly fast

Final verdict

For those who need to move or carry a lot of data, the Samsung T5 SSD is an excellent all-arounder. The T5 shows Samsung at its best when it comes to NAND technology and producing products of high quality with a fast transfer rate and a three-year warranty.

Margin increases when you control the entire supply chain. Comparatively, the Samsung T3 is now much cheaper than the T5, making it a better choice for those who don’t care much about the performance increase. Or for those who plan to use a drive with devices that do not have a 10Gbps Type-C Gen 2 connector.

For now, you are likely to be able to continue using your T3.

Adata SD700 is a rugged storage device designed for users who require an IP68-certified storage device. At least an accidental spill of coffee won’t do much harm to it, but it won’t survive fires.

The SanDisk Extreme 900, on the other hand, delivers higher transfer rates thanks to the use of two SSDs in RAID 0. We strongly recommend that you use a cloud storage solution, as with any external storage device.
