SanDisk Extreme PRO Portable SSD – Review

The device that puts the ’solid’ into Solid State Drive! If you regularly carry around data, or need storage that can take the knocks, a ruggedised drive is for you.

  • Compatibility: macOS 10.9 or later

SanDisk’s Extreme PRO Portable SSD is such a drive. Available in 500GB, 1TB and 2TB capacities, it’s built around a forged aluminium body to protect the SSD core and dissipate heat, with a durable silicon rubber coating for impact resistance. It has an IP55 rating for water and dust resistance too.

The drive is very small and compact, measuring just 110.26×57.34×10.22mm and weighing only a few ounces, it’s an ideal fit for your shirt pocket. It comes supplied with USB-C and USB-A cables (but no carry case), and works on a Mac out of the box, with no driver installation necessary. It comes bundled with an app, SanDisk SecureAccess, which lets you place files in a password-protected vault. It’s a little messy, but it does its job.

On a MacBook Pro using a USB-C connection, it achieved read/write speeds of around 1,050 MB/s, which is fast enough for pretty-much anything. On an older notebook, using regular USB 3.1, it managed read 419.6MB/s and write 416.7MB/s, which is pretty respectable. It’s good value too. The 500GB version works out at 27p per MB, a sum that comes down a few pence if you go for a larger-capacity model. There are cheaper options available, but the Extreme PRO’s ruggedness and portability are advantages worth paying for.

Ian has worked on computer and video games magazines since the legendary Crash and Zzap! 64 in the early Nineties, so he’s seen many changes over the years (including an expanding waistline and receding hairline). A lifelong Mac user, he bought his first Mac in the year 2000. It’s a testament to the resilience of the Mac that his mother is still using that computer to this very day.
