I'm not saying it's nothing to worry about, but neither am I saying it is. Given enough of them it does cause checksum errors on the test pool unfortunately. Could a buggy TRIM play a role here too ? I noticed a commit the other day for a Segate SSD that had a broken NCQ TRIM. Could these units suffer from that ? https://cgit.freebsd.org/src/commit/?h=stable/14&id=47fff7407c22c2c4b36b4f9f27ddfa70bb8f3fee Is there a way to turn that off via camcontrol ? Or perhaps instrument some other settings ? I am not wedded to this hardware, but it would be good to know if they can be made workable without too much effort. kern.cam.da.2.delete_max: 17179607040 kern.cam.da.2.delete_method: ATA_TRIM kern.cam.da.6.delete_max: 17179607040 kern.cam.da.6.delete_method: ATA_TRIM kern.cam.da.0.delete_max: 17179607040 kern.cam.da.0.delete_method: ATA_TRIM kern.cam.da.8.delete_max: 17179607040 kern.cam.da.8.delete_method: ATA_TRIM kern.cam.da.3.delete_max: 17179607040 kern.cam.da.3.delete_method: ATA_TRIM kern.cam.da.7.delete_max: 17179607040 kern.cam.da.7.delete_method: ATA_TRIM kern.cam.da.5.delete_max: 17179607040 kern.cam.da.5.delete_method: ATA_TRIM kern.cam.da.4.delete_max: 17179607040 kern.cam.da.4.delete_method: ATA_TRIM kern.cam.da.1.delete_max: 17179607040 kern.cam.da.1.delete_method: ATA_TRIM kern.cam.ada.0.delete_method: DSM_TRIM # camcontrol iden da3 pass3: <WD Blue SA510 2.5 1000GB 52046100> ACS-4 ATA SATA 3.x device pass3: 600.000MB/s transfers, Command Queueing Enabled protocol ACS-4 ATA SATA 3.x device model WD Blue SA510 2.5 1000GB firmware revision 52046100 serial number 23261Y800771 WWN 5001b448bf6521a5 additional product id cylinders 16383 heads 16 sectors/track 63 sector size logical 512, physical 512, offset 0 LBA supported 268435455 sectors LBA48 supported 1953525168 sectors PIO supported PIO4 DMA supported WDMA2 UDMA6 media RPM non-rotating Zoned-Device Commands no Feature Support Enabled Value Vendor read ahead yes yes write cache yes yes flush cache yes yes Native Command Queuing (NCQ) yes 32 tags NCQ Priority Information no NCQ Non-Data Command no NCQ Streaming no Receive & Send FPDMA Queued no NCQ Autosense no SMART yes yes security yes no power management yes yes microcode download yes yes advanced power management yes no 0/0x00 automatic acoustic management no no media status notification no no power-up in Standby no no write-read-verify no no unload no no general purpose logging yes yes free-fall no no sense data reporting no no extended power conditions no no device statistics notification no no Data Set Management (DSM/TRIM) yes DSM - max 512byte blocks yes 8 DSM - deterministic read yes any value Trusted Computing no encrypts all user data no Sanitize yes block, Sanitize - commands allowed yes Sanitize - antifreeze lock yes Host Protected Area (HPA) no Accessible Max Address Config yes no 1953525168/1953525168
