Looking to increase throughput, and reduce time spent seeking.
(1) Need to increase throughput.
(2) Desire a reduction in the time spent seeking, as a percentage
Current heavy users:
Full Backup going on C:\
A virus scan going (just a quick one, using Windows Live OneCare)
Extracting a 5 GB RAR archive from another PC, over a network, (PC in question only has 100 Mbps, rest of my LAN is 1 Gbps), to remove, or clean, a virus infected file from the RAR archive.
I am doing the above all at once.
I am not 100% certain (read: convinced) that NCQ [Native Command Queuing] is working.
The backup is only going at 4.5 MB/sec, from and to the same HDD, but different partitions, from there it will get compressed, then moved to external storage (be it another PC, or DVD+/-R, external HDDs, etc).
My main questions are:
(1) How do I know NCQ is working, Can I test it with HDTach or a similar tool ?
(2) Heaps of I/O on the one drive:
(2a) The backup is performing all reads + writes to the same HDD
(2b) The extraction is performing only writes (over the network, with my CPU uncompressing the data and virus scanning it).
(2c) The Virus Scan is performing only reads, plus using some CPU time, etc
Pausing the Virus Scan appears to have a minimal difference.
Looking for advice, recommendations, and just a chat in general.
