I purchased one of those promising drives to have it as the boot drive for my omv NAS.
Unfortunately I’m getting quite a few ATA exceptions in the syslog:

A check with smart gave me this

Any idea what goes wrong, why the SSD is causing all those exceptions inside the syslog?
The SMART info actually say quite a bit about some errors occured, from smartctl -x:
Device does not support Selective Self Tests/Logging Warning: device does not support SCT Commands SATA Phy Event Counters (GP Log 0x11) ID Size Value Description 0x0001 4 54 Command failed due to ICRC error 0x0002 4 76 R\_ERR response for data FIS 0x0005 4 0 R\_ERR response for non-data FIS 0x000a 4 8 Device-to-host register FISes sent due to a COMRESET
Thanks for any help!
