TEAMGROUP SSD 4TB 5.0/3.7G CarZ440Q M.2 PCIe TEM

I don't know if the slower speeds would be any different if my cpu was pcie gen 4. my guess is probably not as its below pcie3 anyway. I will retest again when the drive is closer to completely full to see if it gets any slower.drive temps with the msi b550 mpg gaming wifi heatsink when idling is around 35c at 20c ambient temp.hammering the drive with cdm 64GiB temps go up to 41c. I use the top slot closes to the cpu cooler fan.I have not used the included heat sink to see if it is better. as of writing this review I have 2739 power on hours total hot reads 13645gb total host writes 17268gb and 99% remaining life smart data.

4 Tb Pcie 3.0 storage with a decent included heatsink for $150 ... good luck finding that now...

This was the best bang for the buck when I picked it up for a gen 4 drive and it is preforming amazing for my games. Everything loads crazy fast

Bought this to replace my other m.2 and this one is a lot bigger four terabytes to replace my two terabyte one and let me tell you it works very good. I love the speed. It's a PCI Gen 4. Love it! Thinking about buying another one

I had to YouTube the instructions on my own cause it doesn’t come with any, however, I was able to install it once I seen how to do it and got it to work with no issues. No more having to delete any games to make room for a new game I’d like to play.

Incredible replacement for traditional SSD drives. You can't put a price on quality.

Purchased and installed 4TB SSD a couple weeks ago in PS5, installation instructions as far as putting together heat sink could be better. I transfered/played several games w/o any problems. Good drive so far.

Initial performance when installed with a thunderbolt 4 case on a m1 mac mini was 28XXMB/s write and 26XXMb/s read, that's about the best you can expect with thunderbolt.After copying several hundred GB I noticed it was going crazy slow. Figured maybe it was normal because I did a very long long file copy at once (trying to copy my 2TB drive to it) and exceed what the cache and other features could maintain at full speed. Next morning after having the machine off all night, went right into a speed test. Write speed was about 60MB/s for a 4GB file, which is slower than a USB 3.1 gen 2 based case/drive I have. Don't recall what the read speed was, but I realized something was seriously wrong. Tried a few more times throughout the day when the drive was not in use in between and still similar crazy slow speeds.I formatted the drive as a way to make it empty again and right after that it was back to normal speeds. I figured once I started to fill it up again it would get slow again, I wasn't even past 40% full and it should not be slowing that much, so I returned it. Don't know if it was defective, or some other issue on my end, or normal for this drive. My 95% full PNY 2TB Thunderbolt connected SSD in comparison is still blazing fast despite really close to being full.
