- Download Windows 7 Upgrade Advisor here: http://www.microsoft.com/downloads/d...1-2497c146af15
- open a command prompt, browse to where you installed the Upgrade Advisor (standard c:\program files\microsoft windows 7 upgrade advisor beta)
then type:

Winsat disk -drive c -ran -write -count 10

It will run a random write test on your c: drive to measure performance; it will return on single value in Mb/s; more info you can find here: http://support.microsoft.com/kb/940226

On Dell Latitude E6400 with 160Gb Intel X25-M G2 SSD and HDD is encrypted!

On a Dell Inspiron 6400 ...
Realy sucky score

jmke

expected score on a traditional laptop HDD, also gives you a nice indication of possible speed boost going to SSD

I thought X25's were limited to around 80MB/s writes... That looks like an average score?

Here's my results.

jmke

uhm... did you launch via the command line?
the score you see is not pure write commands though

Yes. It starts to run, then crashes about 5 seconds into the test.

That is what I was figuring.

I'm not sure the tool is directly comparable to the WinSat program built into Windows 7 since MS changed the scale/tests around a few times during its development... but I ran the commands on the Windows\System32 WinSat program.

So his notebook HDD beats a 750GB 7200.10 drive? Disk system scores a 5.8 using their # scale.

jmke

if that 750gb HDD is fragmented, it might well be, yes

Ran it again under WIn7 without encryption, same Intel SSD
>> 74.13Mb/s

that's about 18 times faster than your C drive

But meanwhile, my right eye is leering at Snoopy lying on his doghouse (that's my money-box), ready to wring every penny from his gut for an SSD


I'll keep you informed...
