In volume, it is about 40litres, and I'd like to get that down to 15l. I didn't count then add I was moving them. I'd guess maybe 50.

Likewise I have to wonder if small IDE hard drives can always be replaced by small IDE to SATA SSD bridges, or IDE to CF bridges or IDE to SD cards bridges. I can't think of any instances of hearing about that not working. In the case of scuzzy, it seems there are so many scsi to SD adapter so that I'm wondering if there's any point in personally keeping narrow scsi devices anymore.

In terms of vintage HDs CF and SD don't have to be slow. I'm talking theory rather than available adapters though.

I believe ata to CF adapters with udma 220x CF cards should match or exceed most older IDE. Also, I'm less concerned about refunding ide stuff in the future than I am scsi.

That said, people say that Scsi2sd can do 10mbps, which matches fast narrow scsi. 

I'm not aware of any hobbyist targeted adapters doing fast-wide and faster. Thus, I'm sure I should be keeping some ultra wide drives, and some ultra 320 drives. I think ultra wide (not lvd) will work on any wide system. Please correct.me if im wrong. I'm also thinking keep a pair of sas and a pair of fcal, just in case I ever want for testing something.
