Internal Memory CDJ 3000

Hi - Can anyone help. I need to know what the internal memory is in a CDJ 3000. I make my own digital copies of vinyl at 96 kHz @ 24 bit and these take up a lot of working memory. At present I use two Denon SC6000 and each has it's own hard drive connected as the music files are too large to work between the link. And the more Denon add new features the longer it takes for my tracks to load even though they each have there own hard drive.  Someone told me that there is no limit on these players (that can not be correct) but I could plug one hard drive in and my files will work between up to 6 of these players with no issues, does anyone have experience of playing large files between these players. - Thanks
