I remember seeing it before but I can't find it.... Raid 0 (2) Seagate 320Gb drives or some kind of flashdrive or usb jumpdrive? Overall performance which is better for endgame tables and only endgame tables? Thanks...

Flashdrive will win here because endgame tables are all about random accesstime (i.s.o througput).

This is probably the fastest, but impractical small:

I have Corsair Flash Voyager 16GB USB2.0 Flash Drive and sometimes when i am analysing I copy relevant tablebase files to this drive. But 16GB is too small.

Here is one interesting product:

Taipei, Taiwan - March 27, 2007: Samsung Electronics Co., Ltd., the leader in advanced semiconductor technology, announced at its annual Mobile Solution Forum in Taipei that it has developed a 1.8"-type 64 Gigabyte (GB) flash-solid state drive (SSD). The new flash-SSD is based on an eight gigabit (Gb) single-level-cell (SLC) NAND, which provides significantly higher performance over conventional SSDs.

But this is not available yet.

Yes the USB 2.0 pendrives seem like the best deal now.  The 16GB are quite cheap ... but they are not all made the same ... performance can vary dramatically from one make to the other.  I recommend you go on newegg and read the reviews on those drives ... stray away from the ones that have "very slow" in the reviews.  You could probably buy 4 of those drives for 64GB ... but solid state HDD are already available.  The only thing I can see wrong with SSD is that they need some kind of battery.  Gigabyte makes such a drive where you can use DDR RAM and put it in a PCI slot... I don't know if this is similar to other SSD drives, but it does have a problem that is that the battery will lose all information on the drive if it is off a PS for a day or so.  The best solution is to put the most relevant EGTB's on such drives ... but keep the remaining ones on RAID 0 array of cheap SATA drives.

Yes, you are right.
The first games of WCCC i only had a 15000 rpm SCSI drive (Fujitsu MAU3147) for tablebases. For the later games i installed this SSD : http://www.extrememory.de/index.cfm?lang=en&lc=products&nc=pmenue&pageID=11. To use it i had to reduce the number of 6-man TBs. Using it as an external drive reduces performance a lot, so i took it out of the case and installed into the computer. Acess time is now 0,2 ms, running on USB it was 0,6 ms. Great advantage of this drive: you can set Nalimov usage to "Normal".

How about http://www.hyperossystems.co.uk/ Hyperdrive 4

yes that one is probably even faster, but you can only put in 16 GB  - so you'll need 2 of them. And they are super expensive.
