Using the 5 piece Nalimov endgame set from a double lyer dvd

Using the 5 piece Nalimov endgame set directly from a double layer dvd

Have anyone try this?

How well it works compared vis a vis running them from
a)internal hard drive
b)external hard drive via usb port
c) usb pen drive

Thank you for your input

[Gian-Carlo Pascutto]

It will work but it will just be slow. Worse than all other options.

Is there any data to support that running the TBs from a USB drive would be faster than from a regular hard drive?

Since 8gb usb sticks canbe had for about $30 CDN these days (most time even cheaper) this sounds like the route to go.

[BBauer]

Yes, there is.
You may for example run the Eigenmann endgame test for crafty, 1. from disk. 2. from usb stick. Normally you get better results when using an usb stick. Of coarse it depends on the speed of your disk and stick.
Best is to copy the 5 piece tablebases to memory.
kind regards

You may probe the internet, so you can use 6 piece table bases.
This may be worse than using a dvd!
kind regards

probing the internet is probably a good option, once the 6men position is on the board.

Flash drives are indeed faster
some time ago i did a small test:

There was a very good article from the CSS guys here http://www.computerschach.de/index.php? ... Itemid=277
unfortunatly its gone now.
At the bottom of this page there is a list of benched flash drives:http://www.jens.tauchclub-krems.at/dive ... marks.html

Even the cheapest 8GB usb stick (less than $20) is always faster than HD based on my exoerience!
