### ⭐⭐⭐⭐⭐ Great drive great price!
*by J***N on June 7, 2017*

Installed this hard drive and reinstalled Windows 10. Everything worked well with no complications. Seems very fast and quiet and all at a great low price!! Would buy another if needed.

### ⭐⭐⭐⭐⭐ FIXED
*by D***I on January 25, 2026*

Fixed my dad's laptop.

### ⭐⭐⭐⭐ Good basic drive
*by M***J on June 19, 2021*

I have not done any documented testing, but the read/write speeds are better than many of the portable USB drive I have bought in the past. This is not a newer drive, so don't be surprised if the dates on the drive are not recent. This is an inexpensive drive so keep that in mind. Overall it is a excellent drive for the money.
