Compact and very fast – I tried the 2TB version on Macbook pro M4 and iphone 15 pro. Its super fast. I was going for usb 3.2 first as they are cheaper but made a right decision getting usb4 ssd.

Wanna save time and money? – Easy to use, convenient and sleek. The mag safe feature is a game changer. Will free up quick storage and space on your phone so you don’t have to pay extra for iCloud.

CORSAIR – EX400U USB4 2TB External Portable SSD – Fantastic drive. Fast (over 3 GB a sec), lightweight and comes with 2 cables along with being magnetic to your phone. Highly recommend…

Small AND mighty! – Lightning fast and multi-functional. I especially appreciate the MagSafe capability that allows me to attach to my phone or my laptop with ease. Lots of memory availability in a tiny package!

Ingenious design, but the cable needs a fix – This thing is brilliant. It’s lightning fast, and the MagSafe magnet makes it so easy to snap onto my phone. The custom cable also makes connecting it super easy. I love it and would recommend it. My one big issue is that the cable seems sized to fit different iPhones. On my Pro, it gets cramped and pushed into a bend, which wears it out over time. They should fix that, but otherwise this is an insanely well-designed product.
