Question Samsung T7 Touch Portable SSD - 1TB Very Slow

[SimplyWillis]

I just bought this ssd and am using it for general storage with a few programs installed to it. I had the 500gb T5 and I thought this would be a nice upgrade. I tried to transfer the data over (~400GBs) and it was incredibly slow, slowing down to the single digit kb/s after about 15 minutes at what would be normal ssd speeds). When attempting to use the disk at all, the disk activity spikes to 100% usage and stays there (with essentially no reads or writes occurring; <100kb/s). Both usbA-usbC and usbC-usbC cables and different ports have been tried and don't make much of a difference. Crystal Disk Mark benchmark:

. Is it just faulty hardware? I've tried disk defrag/ optimize and diskchk (which came back with no problems).
Any help is appreciated. Thank you!

Show CrystalDiskInfo please!

Can we see your T5 results as well?

Here is the Crystal Disk Info. The T5 performs similarly, though I never noticed the problem with that one. They both seem to wildly range from the scores above to 'normal' ssd speeds (~200 mb/s) on differing benchmarks. I'm beginning to think this is a Windows problem, but I'm not sure what could be causing it. Could it be the drive is indexing each time I write a not insignificant amount of data to it? Usually it seems shutting down the pc entirely and re-running the benchmark will get significantly better results.

Number of error information log entries is high for a new device. You can possibly check these with smartmontools. Also there may be Windows errors (Event Log) related to Disk issues.

12 unsafe shutdowns already too. Have you been crashing or locking up quite a bit lately?

Not a lot I don't think? About the same time I got this drive, I did notice Windows acting strangely. I don't know if it's related to the drive, but when I would attempt transfers, file explorer would lock up, and my keyboard and mouse would freak out. Once, right-clicking would act as left-clicking. The keyboard would continuously type "d" and "e", and other file explorer glitching and weird behavior would occur. It seems to only occur when I was transferring to this particular drive, and not at anytime else. Also, the mouse cursor would become just noticeably unresponsive by about a second. Is it possible for an external drive to cause these errors? Possible a recent windows update?

Have you tried this on another PC?
I will boot my Win10 os and update it to see if mine starts misbehaving but I won't get to that until tonight at the earliest.

I've got the same problem with a new T7 non-touch I've only had a few days. Blackmagic Disk Speed Test says 38mb/s write and 36mb/s read. I've contacted Samsung regarding this and the poor customer support people clearly have no information despite hundreds of comments on forums over the last couple of years.

I also talked to BlackMagic Design who have the T5 pictured with a lot of their gear including the new ATEM Mini Pro + ISO - and they've been getting large numbers of people reporting the same.

I've been trying to use the drive on a few mac's, an ATEM Mini Pro ISO, and a couple of PCs

I'll post if I hear anything new from either.

I've not found any solution online

Had the same Problem but solved it.(Windows)
The drive format was in exFAT when I formated it back to NTFS the speed problem was gone. (For the People who find this over google search and have not much technical knowledge here is how to fix it for windows user: https://www.windowscentral.com/how-format-new-hard-drive-windows-10 for Mac I don't now bc NTFS format is for windows...)
