April 25, 20215 yr As mentioned in the title, I'm having an issue with excessive writes on my cache drive (Intel P3605). I thought this may be related to the existing cache writes issue in previous versions of Unraid, but I'm no longer sure anymore. I've already changed the file system from BTRFS to XFS and verified the partition format is using MBR: 1MiB-aligned. This didn't seem to impact the rate of writes occurring on the drive according to the SMART attributes. In all honesty, the number of writes doesn't seem physically possible. The drive's write speed is rated for 1600 MB/s and somehow it's saying it wrote 0.6 PB of data in 21 hours. For context, I downloaded about 0.5 TB of data in this timeframe (Radarr/Sonarr (cache prefer share) -> download folder (cache prefer share) -> media folder (cache yes share) -> mover to array). I'm hoping this is just a display issue but I'm running low on ideas at this point. Has anyone else used this as a cache drive in Unraid? If so, are you having any issues with excessive writes? Any information or advice would be greatly appreciated, thanks.

April 25, 20215 yr Community Expert Those look like bogus stats, it's still showing 0% life used with 2.22PB written, look for a firmware update.
April 25, 20215 yr Author I'll work on getting the firmware updated and report back if anything changes. Thanks for the help!
