Shopping for the best Mac compatible USB 3.2 solid state SSD backup drive for Apple Time Machine or other data files? Leveraging the current 10GB/s USB bandwidth of a Thunderbolt / USB-C port on modern Macs, NVMe SSD storage is your best option to completely fill it's pipeline and deliver painless and FAST file transfers at an affordable price. Seriously, for 90% of Macintosh users, Thunderbolt 4 / 3 SSD storage devices may be total overkill and far more expensive.

Cheap and Fast 500GB LaCie USB 3.2 SSD For Mac

Comes with Short USB-C to USB-C Cable

Here's a link to another great choice in a USB 3.2 SSD backup drive for your Mac. Be careful choosing a drive: Some still use 6GB/s SATA SSD modules which deliver half the performance and Read/Write speeds that those using a NVMe / PCIe module can. Be sure in product descriptions it states peak transfer rates in the 800 to 1050 MBps range and not just 400-500 MBps range. You'll spit through your Apple Time machine backups, drive cloning sessions or file copies in far less time. It's worth just a coupla bucks more for NVMe PCIe SSD modules inside.
