The experiment has no web coverage AFAIK. It was published "paper only" :-) in
the german CSS computer chess magazine. Author is Günter Rehburg. I wrote about
that article several times, quoting results etc., here and on rgcc:

I don't have much experience with 5-piece tbs., but if I would use them, I'd
care for a tbs. cache of 16 or 32 MB.

Another interesting alternative I tried recently, is tbs. access from a USB
memory stick, or flash memory drive, which you can simply connect to USB port
and use like a disc drive or RAM disk. With a Notebook(WinME) and the memory
stick both having USB 1.1 support, the access times seemed fairly ok to me, at
least with the 4-piece tbs. I had stored on the stick.

Unfortunately, access and transfer times are much worse on another computer
which has USB 2.0 standard (?!). Maybe they would be better whith a USB stick
that support 2.0 too. A magazine article said, these devices are still under
developement. In Europe, good prices for it are 50 cent per MB or less.
