Welcome to stevethornburg.com
The purpose of this page is to provide some comparison data of different external storage devices. At this time, there are only a few devices with test data, and the extent of the data is quite
limited. As I acquire various other devices, I will add test results here when possible. I hope this information is helpful.

I evaluated 2 of each of the devices shown above, doing a fixed data transfer of 1990 files, with a total of 1,197,437,585 bytes of data being copied for each
transfer. I deleted the target files after each copy completed until I had done six measurements for each device, and I averaged those measurements. For each respective device, the values
were surprisingly consistent. This test was started as a matter of curiosity, after having purchased two new Western Digital 500GB "MyBook" drives and being very disappointed at the
slow transfer speed I was observing. Much to my surprise, the external drives I assembled - the Maxtor ATA/133 drives mounted into USB enclosures - were remarkably faster than any of the
others tested. And a side benefit is that they cost about half the price, too. I found the DaimondMax 300GB drives on sale for $80 each, and the enclosures were $22 each. So for just
a little more than $200, I got 600GB of very fast external storage. Update: 02 OCT.06 - I found two Maxtor 6H500R0 500GB ATA/133 drives on sale for $109 each. They are 7200 RPM, and have
internal 16MB cache. I mounted these in USB enclosures, same as previously described. Test results shown below.
Each test scenario was done using Karen's Replicator. In my opinion, the Replicator is an excellent utility.
