We just purchased a new 1850 server (2x3.4 Ghz) with 8GB of memory and
a dual channel PERC 4e controller (internal drives are on their own
controller); each channel is connected to 6 36GB 15K drives for a total
of 12. I had our server folks build 3 RAID 0/1 arrays of 4 disks each.
We're running Windows 2000 Advanced, and this is going to be a database
server (running MS SQL Server 2k).
While setting up my databases, I had occasion to copy a 21 GB file from
one array to another. Using standard Windows drag and drop, I'm
averaging only 30-33MB per second for this copy with no other load on
the disks or system. This seems kind of slow to me based on typical
hard disk transfer rates I've seen on storagereview.com and similar
sites; I'd expect at least twice this amount.
Are my expectations unreasonable? Does Windows have that much of an
overhead? Or is there possibly an issue here?
Reply here on the newsgroup please.
Thanks,
