SanDisk Extreme Pro Portable SSD V2: bigger and faster

We have already tested external SSDs from SanDisk several times. However, it has always been a model of Extreme Portable SSD, namely from 2018 and 2020. However, the manufacturer also offers another model, which it refers to as Extreme Pro Portable SSD. We have tested its second generation from 2020 in detail and we will be interested in whether it’s worth paying extra for the “Pro” label or whether you can do with the base model.

Read: practical tests

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 the 20 Gb/s Pro V2 mode at the front places and in close proximity to the P50. In this case, however, the Thunderbolt models are already achieving even higher speeds, which is not surprising given the connectivity bandwidth. The situation in the 10 Gb/s mode is also repeated, where the Pro V2 achieves slightly better numbers than the base V2 version of Portable SSD.

Read: synthetic tests

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 show a similar scenario as with write, i.e. lower performance in 4K tests and leading ranks in the sequential test.

External SSDs, News | | Ľubomír Samák

External SSDs are not always favorable in terms of price. Compared to the price of an SSD and an enclosure itself, manufacturers like to be paid extra for the highest-performance models. Otherwise you might buy a cat (no-name SSD) in the sack, etc. Now, however, there is a good opportunity to buy an extra fast SilverStone MS12 enclosure and an SSD in M.2 format according to your own taste. And in terms of architecture, it looks quite attractive. Read more “Silverstone attracts with a 20-gigabit enclosure for external SSD” »
