Confused with numbers

Hi,
When backing up to my memory stick the programme tells me the data is going in at a rate of about 60 KB per second but 7,225,773 KB of data is actually copied in around 25 mins which equates to a rate of 4632 Kb per second.
Am I missing something or is the programme just wrong ?

Regards Alex

 

What program?

 

Hi,
The programme is Macrium Reflect Free, the disk imaging software

Cheers Alex

 

Is it an estimate? If this is the case it may just turn out it's just not super accurate.

 

60KB!! Are you sure. Doubt there is stick that slow. 600KB equates around about.. Do the math. Cheers

 

Hi,
Yes I have done the maths and thats what worries me.
Macrium shows me [as the back up is actually happening] that the data is going in at approx 60KB per sec. I say approx as it keeps varying. That equates to 3,600 KB per minute. It runs for 25 min so we have 90,000 KB
At the end I actually have a disk image of 7,225,773 KB which is an input rate of 4,632 KB per second. That seems a high figure but it comes down to a disk image of about 6.9 GB . Macrium compresses the 12 I have down to 6.9.

Alex, you are mixing up your kbps and kBps. It's bits and bytes. Bytes being 8x

So for confusion's sake 90000*8 is close to 7,225,773

And 60KB transfer is wrong.. So it's all kinda wrong Cheers

 

Hi,
Help!
With you on the bits and bytes but 90,000 times 8 is 720,000 so we are out by a factor of ten.
Cheers Alex

 

Hang on I was pulling your chain
Do the math:
7,225,773/60sec/25min=4817kb/8 = 602 kBps

 

Hi,
So it's going in at 600kB persec and not 60 .
Ok
Cheers Alex

 

Cheers Halo
