As we can see, it's about 9-10 times faster than regular consumer SSD available at this time.
RAM drives are volatile memory (require power). This does not worry me because i can easily re-copy egtb from another back-up HDD if power shut down.

RAM drive
Are there any other cons than limited hash table for engines for analysis if tablebases are stored on ram disk.

If the files will fit on the RAM drive, then they will fit completely into memory.Nordlandia wrote:Are there any other cons than limited hash table for engines for analysis if tablebases are stored on ram disk.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Why RAM drives don't make sense here has been explained many times here, and probably 9 out of 10 times in response to this very same question from the very same OP.

Re: RAM drive
I see huge egtb boost in performance from nalimov/gaviota 5-men. Nalimov & Gaviota use different hash algorithm.
Syzygy get stored in RAM
Nalimov & Gaviota does not get stored in RAM.

Usually an OS uses unused memory as a disk-cache which is comparable to a ramdisk, in a way.
