Final Opinions
I like this drive! It’s nice and fast for reading, good enough for writing; small, lightweight, affordable, and a sleek metal design that helps with temperature control. On that topic, I have noticed the drive gets a bit hot after normal use. It’s not uncomfortable though, and cools down fast when idle.
It’s mainly disappointing though that write speeds for portable USBs continue to be so poor. Realistically, for fast writes, you’re best off with a dedicated NVME or SSD external. Heck, a portable NVME unit can not only be thin and portable, but insanely fast if connected to proper interfaces.
All in all, can recommend this drive. :+1:
