October 4, 20169 yr As the title says, my parity check is extremely slow. I see people complaining about 10MB/s being slow and I am getting less than a quarter of that. What can I check to figure out why. Diagnostic information attached. My System: CPU: Intel® Xeon® CPU E3-1230 v5 @ 3.40GHz RAM: 16GB DDR4 ECC MB: ASRock E3C236D2I Mini-ITX SATA: Onboard, M.2, SYBA SY-PEX40039 Plug-in Card SATA III Cache: ADATA SSD SP600NS34 256GB KingDian SSD S280 240GB Pool: 3x WD Red 4TB 1x Seagate ST4000DM000 4TB 1x Hitachi HDT721010SLA360 1TB Parity: Dual (1 WD Red and the Seagate) aeris-diagnostics-20161004-1045.zip
October 4, 20169 yr Lots of read errors on disk2 (which you should see in the webUI if you look), but SMART looks OK so maybe just a bad connection.
October 4, 20169 yr Author I actually don't see any read errors in the UI, where would I see that? Sounds like I might need to start considering replacing that drive.
October 4, 20169 yr Errors should be visible on the main page. Although there are no pending sectors errors look like a bad disk, you can confirm by doing an extended SMART test.
October 4, 20169 yr Author Ah, found it, yes, it shows 482 errors. I am playing it safe and just ordered two replacement drives (going to get that 1TB out of there as well). Side question, anyone see any issues with this as a home NAS drive, other than the heat (I realize the REDs are lower power) http://flash.newegg.com/Product/9SIA5AD4NC7705
