Been upgrading an old T420, this was a nice cheap drop-in that gave it plenty of storage. Be warned that there are faster and better SSD's out there (the main drive i'm using is a samsung 850, which twice as fast), but this is a great balance of cheap and fast-enough. And at any rate, it's far better than a spinning platter drive.Benchmarked at 261MB/s on Mint's built-in disk benchmark tool, on the t420 in question itself.

Premiun SSD with Good perfomance, stable, no problems so far, highly recommended for those enthusiasts who are only looking for the best of the best in quality, especially if you are looking for SSD or NVME with Nand TLC Memory.

I purchased this 512GB mSATA SSD to install in my Protectli FW6A firewall. Good price and easy installation.

Original drive that I bought was defective, but the seller was flexible and offered a refund.
