Works great - Easy to install and easier to use. The price for this expansion in storage was excellent as well.

Great, cool, and fast. - I bought this SSD in 2025 to replace my old 512 GB NVME drive, and I’ll say that this drive runs pretty fast and holds up to anything I throw at it. The heatsink is a pretty nice bonus for sustained transfers, and to help with the fact that my GPU directly blows hot air onto the SSD slot for some reason.
