How do I determine the read/write speed?

[NightShade737]

That must be a relitively old PC, as that is quite low. My machine I am using now gets ~60MBps (read and write).

My Amigas 840MB drive on my A1200 got roughly 1.7MBps which is dire. I wonder how much my new Seagate cheetah will get on my CS's SCSI when they both arrive...

Crumb: I assume you are refering to disk cluster size as opposed to block size.

I don't know a squat about the test I did. I just did a search on google and downloaded this program:

http://www.pcworld.com/downloads/file_download/0,fid,16880,fileidx,1,00.asp

it's name is Mpow V1.2

I selected the 65536 block size and the 1MB file size, that is also mentioned above in the output... :-)

But that's not the point here. I jus want a driver for a decent harddrive controller to the Amiga.

I'm refering to the size of the clusters of the hard disk, you can change this size in the advanced preferences of HDToolbox. Windows systems usually have 4kbyte clusters, Amigas 512bytes or 1kbyte. Changing that setting to 2-4kbytes improves the speed.

After reading your comment I remember that on most hd speed benchmark programs you can select the size of the data to be written to hard disk, well, I wasn't refering to this, but yes, you are right it's another setting that should be included in any benchmark.

And remember that an empty hard disk is much faster than a full one...

So anyone who makes a benchmark about disk speed should give information about:
The filesystem used and the cluster size (I'm used to the word "block" size, I think that HDToolbox uses this name)
The model of controller and HD
The buffers the volume had.
The HD was empty or full
The X MB/s he got transfering chunks of Y Kbytes reading (or writing)

clusters size in HDToolbox?!?
Are you sure?

I don't know if the name in english is cluster or block. But simply select a partition, enter in the advanced options and search an option called block size or something similar, it's usually in 512bytes as default...
