See Sonnet’s tech specs for additional details. For that reason, double-sided memory component M.2 SSD media is not recommended. Keep in mind that Sonnet says that only SSDs with memory components on the top side of the module are compatible with this card. Sonnet pre-filled four Samsung EVO 970 M.2 SSDs for me to test, which offer sequential read and write performance levels of up to 3,500 MB/s and 2,500 MB/s, respectively. Setting up the unit is just a matter of unscrewing the outer cover, removing the heat sink, and depositing four drives. The x16 card, which features four slots for four single-sided M.2 blades, allocates four PCIe lanes per card. Sonnet reached out to me last week to see if I’d be interested in taking its M.2 4×4 PCIe Card for a test drive in my Mac Pro, and I happily obliged.

Watch our hands-on video review for the details. When paired with the right SSDs, the Sonnet M.2 4×4 PCIe Card produces speeds of the bonkers variety.ĭuring benchmark tests with the Blackmagic Disk Speed Test utility, I was getting write speeds in that easily surpassed 6,000 MB/s, and read speeds that eclipsed 7000 MB/s.įor comparison’s sake, Apple’s fastest 8 TB SSD produces speeds “only” up to 3400 MB/s, so this setup is capable of running circles around the Mac Pro’s fastest built-in SSD for less money. If you’re looking for the fastest SSD available for the Mac Pro, then this may be the solution for you.
