hello Alex.
Yes but it looks to me, that benefits, was not all because of that. Don’t have evidence for that because i would need to repeat the operation, but this time not to format the 4TB after backing up files from it, but shift+delete all disk, which would took some time. And robocopy on empty but not formatted disk to see isolated effect of only defragmented files landing speed. I have another 4TB disk like that so i can technically do it for science.
Now i discovered that on 2nd 16TB disk, full with storj, disabling to create 8dot3names actually unlocked robocopy write speed like 5 times! :
Oh snap, and also striping existing storj files does same for read! Whoaaa:
Dear Diary: Details of unlocking write/read speed for a 16TB disk
Day 1710 of being a Windows SNO:
robocopy from 4TB (formated win10) to 1_3_16TB(win7 formatted, full of storj and slow, with 8dot3names Enabled)
is stuttering, because of max write speed of 1_3_16TB i see.
the read is at full 50-60MB and stops to wait for write.
which is at max 13-15MB/s shows me taskmanager
-ops after a minute its suddenly unlocked the write speed and is now 14Mb-108MB and not stuttering, but spieks up and down but constant flow
wonder if read speed also unlocked? as i checked was slow on storj’s files at 1_3_16TB,
lets see
yeap its very slow read from 1_3_16TB
lets see a robocopy from it to the fast now 4TB
yea read is at 6-9MB/s so is write is.
lets “fsutil 8dot3name set g: 1” now so disable and see now
quite OMG, the 4TB now writes what 1_3_16TB is able to throw at it with avr. of 65MB/s speed, because the write is spiked and its from 24-100MBs, but its constant, so it keeps up!
so disabling creation of 8dot3name worked for unlocking a write speed of a new files under Win10 Os of a disk, that was formatted under win7!
probably it did not for reading speed of what already been written with that lets see:
yea it did not, but we can try strip that folder we are reading and see:
“fsutil 8dot3name strip /s /v G:\Storj\blobs\qstuylguhrn2ozjv4h2c6xpxykd622gtgurhql2k7k75wqaaaaaa”
and its stripping it, not sure the speed task manager shows in KB/s but thats not file copying speed, so can’t really compare, the writings on the CMD moves as fast as files under robocopy did, so maybe its fast enough so i can check for a moment if the reading of a folder under windows properties was changed for better, lets wait and see.
after 30minutes, it went for 1/4 of subfolder in that blob, i just can’t wait to check
a “br” folder windows says, it contains 154MB, and the strip went thru it in ~4s i counted in my head, so maybe the real speed is around 38MB/s, that would be not so bad.
lets pause it then and see,
OMG yes, it counts files really fast now on, up to point, the folder is stripped, then it counts it slow again, so yeah, striping 8dot3name works here with 1_3_16TB for unlocking a read speed for small storj files!
So i guess i don’t have to format these disks, but just to stripe!
this disk is not defragmented, its fragmented like crazy rather. And here, the read speed is great!
