The Extreme Pro SSD joins a growing range of SanDisk external SSDs. With an NVMe SSD (WD Black SN750) inside it and a USB 3.1 Gen 2 Type-C interface, it certainly is a fast performing external drive. It is available in three capacities; 500GB, 1TB and 2TB.
The only official performance transfer rate figure in the spec sheet for the drive is a read speed of up to 1,050MB/s. Using the ATTO benchmark we couldn’t quite reach this maximum figure, the best we saw was 1,027MB/s. Write performance topped out at 972MB/s. The more intensive AS-SSD benchmark produced read/write figures of 954MB/s and 905MB/s respectively.
Using the various profiles in CrystalDiskMark 7 we saw read performance figures of 1,026MB/s for default and peak performance with a figure of 858MB/s for the real-world profile. Write performance for the drive averaged 967.5MB/s for the default and peak performance profiles with the real profile producing a figure of 884MB/s.
Real-life file transfers when transferring data to and from a Samsung SSD850 PRO saw write performance go beyond the 500MB/s mark when dealing with large file sizes. However, switching over to another NVMe drive (Kioxia RD400) saw read speeds over 900MB/s and write speeds over or close to 700MB/s when dealing with the same large file sizes.
Although the Extreme Pro SSD comes with an IP55 water-dust resistant rating thanks to its silicon rubber coating, it’s not as water-resistant as some of its competitors as the USB port doesn’t have a cover of any sort so you still need to take care when you have it in a bag or pocket.
The drive comes with SanDisk’s SecureAccess utility loaded on the drive ready for you to install. The software creates password-protected 128-bit AES encrypted folders on the drive, but make sure you remember the password as there is no option to re-set it should you forget it.

KitGuru says: SanDisk’s Extreme Pro SSD is a fast, pocket-sized drive with the added bonus of being able to easily encrypt sensitive data. It’s just a shame that the USB port doesn’t have a cover to protect it.
