No issues and is nice and fast, but if you are running Linux then currently trim is not supported. Both Gigabyte and Corsair PCIe 4.0 NVMe's have this issue (some details can be found in this thread https://ubuntuforums.org/showthread.php?t=2422973&page=3).

Advertised as having a read speed of 4950MB/s, for some reason that speed was not achieved in the benchmarks I ran, despite having a PCIE 4.0 system. I'm not sure why it didn't achieve these speeds, so take this review with a grain of salt. It could be the case that it was just the benchmarking software not keeping up, or even that there is some driver or another that I haven't installed which would have made a difference. Still faster than any gen 3 PCIE SSD I've used.

Excellent performance sums it up. Be mindful of motherboards with their own onboard M.2 heatsinks. Some motherboards are designed in a way that you can not use M.2 drives with the heatsink that come with. Example the ASUS ROG STRIX X570-E.

Quick install, and doesn't run hot compared to others I have without the heatsink

Had this for a couple of months now. Use in a 4k video editing machine. Things run very smooth with this drive.
