So how do you know how good or how back your computer is?
If you have a Vista workstation you already have the tools you need.
Click start, find accessories, find command line, right mouse click and run as administrator.
Type in winsat disk -seq -read -drive c
(that checks the c drive)
C:\Windows\system32>winsat disk -seq -read -drive c
Windows System Assessment Tool
> Running: Feature Enumeration v1.0.0.0 ''
> Run Time 00:00:00.08
> Running: Storage Assessment v2.0.0.0 '-seq -read -drive c'
> Run Time 00:00:15.14
> Disk Sequential 64.0 Read 36.81 MB/s 4.8
> Total Run Time 00:00:17.49
C:\Windows\system32>
That's my old baby laptop. Not so good.
C:\Windows\system32>winsat disk -seq -read -drive c

That's the workstation at the office.
BIG difference.
