The SanDisk Extreme Portable SSD was one of the first external SSDs we’ve tested. After the test, it became my sidekick and I’ve been using it to this day. However, some time has passed since its introduction in 2018 and the manufacturer now brings a revised version with the same name. The novelty has double the speed in specifications, hardware encryption and several improvements of the insides.

The tests consist of sequential transfer of directories from the RAM disk to the SSD. The files in these directories vary in size. From the largest 9-gigabyte one (when most SSDs reach maximum performance), the file size gradually decrease to very small (12–59 kB) – in such operation, the performance is usually relatively low.
Practical read tests also show an improvement of about 60%, but the jump with 427–1235 kB and 12–59 kB files is interesting, where we observe improvements of 110 and 132%.

The results come from the AS SSD benchmark. The size of the library is set to 1 GB, which means that the measured values do not yet reflect the limitations resulting from the full SLC buffer, which is an integral part of most fast, cheaper SSDs with TLC memory.
Synthetic read tests again ranked this SSD between PXD and My Passport SSD, although SanDisk loses in access time and 4K (64 Threads) by about 50%.
