The Sonnet M.2 4x4 PCIe Card adds insanely-fast SSD speeds to Mac Pro

9to5mac.com

The Sonnet M.2 4x4 PCIe Card is a powerhouse, offering staggering SSD speeds that leave Apple's built-in options in the dust, all while being more cost-effective. Installation is straightforward, and the RAID 0 configuration with multiple SSDs provides lightning-fast file transfers—ideal for video professionals. However, it's crucial to note that this card doesn't replace Apple's encrypted SSD, which has its own set of limitations, including booting and compatibility issues. While it dramatically enhances storage performance, users still need to navigate a few technical hurdles. Overall, it’s an impressive addition for those looking to maximize their Mac Pro's capabilities.
