Just be warned external spinning hard drives are slow, slow slow by todays internal SSD drive speed standards. (Since upgraded with a much larger faster ssd component to the fusion drive which more than doubled the iMacs drive performance.) It’s actually faster as a external boot drive than the original internal 2017 fusion drive in my iMac. The WD black is about as fast as a single 3.5” spinning hard drive can achieve, was reasonably priced, and the $30 dongle can be moved between my archive drives with ease.

A Samsung or western digital were my other proffered options for ssd brand.įor bulk storage I choose a Western Digital Black 4TB 7200 3.5” bare with a usb3 to SATA dongle because the drive will rarely be moved around. My preferred brand for the case is Orico (only one I could get my hands on), and I went for a mid range P.2 crucial drive which would just about saturate the thunderbolt connection, and well suited for high write contexts (such as as a boot drive) to give maximum iOP lifespan. Fast, bombproof reliable, with a certified connection technology well suited to your Mac. If your prepared to spend the money: a thunderbolt 3 or 4 case with a M.2 NVMe PCIe SSD, 2TB.
