The older ISA (now called PATA = Parallel ATA) has been replaced by SATA (Serial ATA). SATA has 3 speeds. Most new disks are either SATA 2 or SATA 3 speed.
IDE I assume you meant. :) ISA was the old bus PCI replaced.
Yes, but, technically PATA is a souped-up ISA bus with address decode already done for all but the lower few bits. Old 16-bit ISA IDE cards were often referred to as paddleboards because the only thing on the card was a small address decoder/buffer chip and the rest of the lines went virtually straight through from the ISA bus to the drive.
So saying ISA is only partially incorrect. :-)
