I load movies onto the PC and connect it to the Mibox on the TV. I can now watch all the 4K movies without any lag. It is incredibly fast in copying and transferring files

Lightweight, fast, small, and quiet is exactly what we need.
I had ordered two and one had a problem, even though it was during Easter, it was replaced within four days. Skroutz came and picked up the faulty disk from my house and delivered it back to my house in four days.
Congratulations!

At the moment (if I'm not mistaken), an M.2 is conventionally the fastest hard drive in terms of speed, I don't know about durability (not just mechanically) but also in terms of data (backup), because if it's like SSDs, they can crash and you lose your data. It's lightweight, small, slightly larger than a regular USB flash drive, and the cable makes it bulkier.
In terms of speed, I tested it on a USB 3.1 PC desktop with the Crystal program... it reached 50Gb/s (yes, you read that right). Then I tested it on a laptop with Crystal again, and it reached 470Mb/s, so if it's used with USB 3.2, it could potentially be even faster.
I believe it's worth it for fast file transfer with the appropriate system, but I have some reservations about permanently storing personal files, ONLY on such hard drives.

Flawless disk, excellent connection with MacBook M2 2023, very good quality, very fast data transfer, highly recommended

I put it in a PS4... and it kept losing connection!!!
We formatted it and put it in another PS4... same thing!!!
[However, it works perfectly on a PC!]
