chrisj979 Posted March 22, 2009 Posted March 22, 2009 Hello all, here is my problem, this is NOT the same Vista file copy slow. I have noticed when I transfer files to a share on my 2008 server the speed is between 20-35MB, but if I transfer a file to the admin share like C$ the transfer speed is 80-110MB. Why is there a difference and is there a way to get the share transfer speeds up to 80MB+? What am I missing? OK after some more research I see that if I create a share on C: I get the high transfer rates but a share on any other drive the speed is between 20-35MB. All of the drives are 15Krpm SAS drives, all connected to the SAS 6/iR controller. So why are my transfer speeds to C: so much faster than to the other drives if they are all the same? Thanks in Advance, Chrisj979 Quote
chrisj979 Posted April 7, 2009 Author Posted April 7, 2009 OK, sorry it took so long for me to get back to everyone but I had to defrag all my volumes thinking that was the problem but that was NOT it but hey my drives are WAY less fragmented now. Then I noticed that when I copied something to a share not on C: it would copy some then pause then copy a little more then pause and continue this until the copy was complete, as if were writing to another location first then to the share where I wanted it to go. FINALLY, it hit me, like a ton of bricks falling out of the sky, DRIVE COMPRESSION WAS ON FOR ALL THE DRIVES EXCEPT FOR C:. DUHHHHHH, So it was compressing the file as it copied it over that's why it copied a little then paused, then copied a little more and so on. So add that to the list of things to check when having file speed problems. Yes I know ID10T error or DFU, I'll accept that. Thanks for all the assistance though team. Have a good one. Quote
