PATA 133, SATA 150 or SCSI U160 for 486 PC

Postby Bellator » 2019-1-06 @ 13:08

I would like to speed up my 486 PC by replacing my IDE PIO 4 HDD (max transfer rate of 16,6 MB/s) with a much faster one. So I am considering to install a PCI controller card to take advantage of the PCI bus max transfer rate of 133 MB/s.

I am hesitating between PATA 133, SATA 150 and SCSI U160 types of controller cards. What advantages does each type have over the others in this case? What would you recommend?

With a lot of the pata pci controllers you simply won't be able to boot from them in 486. Best chances you would probably have would be with a SCSI card with a bootrom and it would be nice if the bios has boot from scsi option.
