Buffalo presents a tiny and 15 g USB Type-C SSD
There are multiple compact SSDs on the market, but few are as small as the Buffalo SSD-PSMU3. While the Samsung T5 or T7, for instance, tip the scales at 51 g and 58 g respectively, the SSD-PSMU3 weighs just 15 g. The SSD-PSMU3 is smaller than the Samsung T5 and T7, too. Even the HyperDisk is a touch bigger than the SSD-PSMU3. Additionally, Buffalo claims that the SSD-PSMU3 is MIL-STD 810G certified, meaning that it should withstand the stress and strains of daily use, including drops from up to 1.2 metres.
Buffalo sells the SSD-PSMU3 in 120 GB, 250 GB, 480 GB or 960 GB variants, all of which will support USB 3.2 Gen 1. There is only one port on the device, a Micro B, but Buffalo includes a USB Type-A cable and a USB Type-C adapter in the box.
The SSD-PSMU3 is rated for up to 430 MB/s, although AnandTech notes that this may be closer to 400 MB/s in real-world use because of 8b/10b encoding overheads. The drive also supports Buffalo's SecureLock Mobile2 technology, which uses AES-256 encryption. It is unclear whether this is software or hardware-level encryption, though.
Buffalo sells the SSD-PSMU3 in aquamarine, pink and white. Currently only available in Japan, prices range from ¥5,700 (~US$56) for the 120 GB model to ¥22,300 (~US$218) for the 960 GB mode excluding taxes.
