2.5 PATA HDD with capacities higher than 320 GB

ditto for the 3.5"

I can’t find anything over 320GB

I have 3x 3.5" WD 500GB E-IDE disks

at one time there were also 750GB E-IDE WD Disks

I have a ton of systems that have empty 48-Bit LBA ATA controllers that
I could be using with some large E-IDE drives for Data storage
