These days it's increasingly common to see tmpfs mount on /tmp rather than persistent storage; and then at some threshold it uses swap. So I'm unsure this is a reliable testing source or destination. What results do you get for the same test using /dev/zero to /tmp and /tmp to /dev/null? trimmed: > root@homeserver:/mnt/BTRFS/Video# smartctl -a /dev/sda1 > === START OF INFORMATION SECTION === > Model Family: Seagate Barracuda 7200.14 (AF) > Device Model: ST3000DM001-9YN166 > > SMART Attributes Data Structure revision number: 10 > Vendor Specific SMART Attributes with Thresholds: > ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED > WHEN_FAILED RAW_VALUE > 7 Seek_Error_Rate 0x000f 073 054 030 Pre-fail Always > - 34538763506 The raw value is typical for Seagate drives, but the value and worst compared to threshold would concern me. The value should be at 100, ideally, for a completely normally functioning drive. It's OK if it dips below this and there are no other problems. But worst value 54 is pretty close to threshold 30, it's just not low enough to trigger a prefail warning. It's worth sending the data to Seagate and seeing what they have to say about it if it's still in warranty.
