    Super fast!
    Updated review: holy cow this is fast. I bought a new iMac and backed-up my MBP with this. While transferring to the new iMac I was seeing speeds over 1G/sec. Very sweet! Had zero issues with compatibility, connection, or use. MBP was a 2019 model with Thunderbolt 3. iMac is the new one with the M3 processor and two Thunderbolt ports. Thrilled with how fast I transferred 1.5T of data.OG review: Fastest external SSF for a Mac out there, but no where near the speed they advertise. I’m using it solely as a back-up/Time Machine disk. I’m moving from a MBP to an iMac and wanted to be able to transfer quickly. Backing up the MBP now and I’m getting about 20G per minute. I’ve got to transfer 1.5T so being faster than most helps.

    Using in on my M3Max MacBookPro - this 4TB thunderbolt external drive is crazy fast (see photo).

    I use it for Lightroom editing have have zero complaints. Ran me $387 (listed as 52% off at the time) in Feb 2024 - which is far cheaper than I could built it.

    It gets warm to the touch, has an indicator led, is ruggedized, and has worked in every port and dock I've tried it in flawlessly. No idea on longitivtiy at this point, but damn it is fast and at a good price point.

    Considering grabbing a few more.
