Should have bought one years ago! - I’ve been doing more video editing and this external drive was a lifesaver for my MacBook which was filling up. I ended up offloading a lot of stuff and my computer runs amazing now! This was a pricier drive but it was considered one of the top options for video editing because of its speed. It’s so easy to use. I should have done this a long time ago. It’s ready to go for Mac just plug and use! The plug it comes with must be used with it to achieve the speed needed for video editing. Highly recommend this drive. Hard to believe 2TB is so small! Smaller than an iPhone.

Work great with Mac - I use this for my desktop Mac mini. Has worked find so far and has plenty of space for me and my family. Love the size. Does not take a lot of space on my desk. And very quiet.

Great so far, but definitely pricey - So far, so good! I haven’t had this drive for very long, but I haven’t experienced any issues with it yet. It’s fast, easy to use, and has worked well for storing and transferring my photography files. My biggest complaint is the price—it’s honestly kind of crazy for 2TB of storage. I’m hoping the higher price means better reliability and longevity. Time will tell, but so far I’m happy with the performance!

Very Fast IO - I use this for sound libraries and plugins on my Mac Studio Ultra via a Thunderbolt 4 port. Wicked fast !
