  • Very good SSD. Hope it lasts!
Style: Standard
Received the SSD and the performance is very good. Coming from a HDD it really made my home server snappy. Read the negative reviews so I am keeping a couple backups just in case, but until now it is working very good. I took a chance because it was very cheap!

  • Perfect. Just perfect.
Style: Standard
Standard form factor using standard sata and standard power. Screwed in to my case very easily, and had no problems connecting. I transferred my Windows installation from a smaller SSD to this one, and it went over smoothly. Silent drive, with quick data access. I bought the same product in 256gb four years ago and it works fine still, so this will last you until you fill it ;). ... show more

  • Great Drive
Style: Standard
I was a little disappointing that neither Windows 11 or Linux would recognize the SSD from my USB enclosure until it had been formatted. Other than that, it is a wonderful drive. My UEFI Bios detected the drive immediately after it was installed internally in my PC. Works great as a secondary drive for my Linux files. It is currently formatted using ext4. I have tested it with both NTFS, and brtfs file systems. Would recommend for anyone looking for an inexpensive SATA SSD option. ... show more
