February 22, 20188 yr Community Expert I've been experiencing inconsistent read speeds, more so for one particular share which is localized to one disk (sdm) - at least that's what I can gather - and seems to happen with SMB on a Windows 7 box and via Mac OS X as well. Certain files under this share do 7-8Mb while others can go upwards of 70-80Mb. Seems to happen with one specific folder on the drive.... Does it make any sense that this would be the case? Not sure what's going on here. Attached a smart report of concerned drive. Running 6.4.1 under ESXi.

Really not sure what's going on here. I've changed the drive, SAS cable and even swapped out the M1015 for another, same slow read speed.

However, I just realized that a recent change could be the culprit. I recently moved my downloads to a user share (which is on this one disk) that could be impacted my tests and leading me down a rabbit hole. I had originally had the mind to slap in a crucial 750gb MX300 ssd as a download drive and for use with dockers as well, but after reading about TLC drives I opted not to do so. Instead now, I have a small (120gb) Intel ssd for my docker images and put the downloads on a user share. Not sure I like this approach though. I may go back to using an unassigned disk outside the array for downloads, dunno... I'd much prefer to slap everything on an ssd though. Edited March 1, 20188 yr by joelones
