Pros and cons

According to our solid state drive (SSD) expert

You can transfer large files quickly thanks to the high write speed.
With an M.2 NVMe SSD, you can open and transfer most files faster than with other SSDs.
The 4TB of storage gives you enough space for large files, big AAA games, and backups.
Without a heatsink, the SSD heats up faster, so there’s a higher risk of slowdowns.
You need a higher read speed to open the most demanding programs, games, and media faster.

Review is 9,5 out of 10.

Definitely recommended for home use in a mini server.

Very fast SSD, all services on my homelab feel very snappy because of it.
It also does not get too hot and is therefore extremely suitable in the small housing of e.g. the Dell Optiplex Mini.
Not discovered yet, if any problems arise I will adjust the review.

I use the NVMe SSD in a home lab, a mini server (Dell Optiplex mini) on which I run multiple services simultaneously in containers and VMs. Everything feels smooth thanks to the speed of this SSD.
