May 17, 20179 yr I've just added my parity drive to my array, but I think it is lacking ALOT in speed. I'm seeing reads and writes speed about 37-40 mb/s. Is this normal speed or do I have a serious speed problem ?
May 17, 20179 yr Author As you Command Johnnie I've also just noticed the 38 errors on disk 1. It doesn't seem to rise though. tower-diagnostics-20170517-2216.zip
May 17, 20179 yr Community Expert Disk1 has issues: Device Model: WDC WD40EFRX-68WT0N0 Serial Number: WD-WCC4E4JHAA64 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 1 Parity won't be 100% correct due to those reading errors. There are also constant USB disconnects logged: ...

As for the low speed, I know HP Microservers have a write cache setting in the bios (disable by default) that's gives similar write speed, speeds become normal when it's enable.
May 17, 20179 yr Author Hmm don't remeber having turned off write cache. but will check. As for the USB, nobody seems to be able to find out what those error are. I have only one drive in the server, that is the Unraid USB key. It has been the same error no matter what key I used, I have tried different keys, 4-5 keys, usb 2 and 3's

Default is off, at least on the Microservers. 11 minutes ago, Kaltar said: As for the USB, nobody seems to be able to find out what those error are. Look for a bios update but probably not serious (except for filling your syslog), you main problem ATM is disk1.
May 17, 20179 yr Author Yeah i'm using the newest bios on my proliant ML310e g8 server, så that can't help sadly. As for the Write Cache, you are a GOD sent Johnnie, didn't know I had messed with it, but apparently I had, because now i'm seeing read and write speeds in the range of about 155-160mb/s on my WD Reds. As for the Disk 1 I think it is still under warrenty, so I'll just have to move all data away from it and fill out the RMA.
