Is PCMCIA as fast as USB 2.0? That is, if I use a USB 2.0 card on my laptop, will I be able to fully utilize a 48x CDRW with this enclosure? If not, what is the maximum rate that you can burn at with PCMCIA?
How fast is USB 2.0, and how does it compare to others?
(from usb.org)
serial port: 115kbits/s (.115Mbits/s)
standard parallel port: 115kBYTES/s (.115MBYTES/s)
Original USB: 12Mbits/s (1.5MBYTES/s)
ECP/EPP parallel port: 3MBYTES/s
IDE: 3.3-16.7MBYTES/s
SCSI-1: 5MBYTES/s
SCSI-2 (Fast SCSI, Fast Narrow SCSI): 10MBYTES/s
Fast Wide SCSI (Wide SCSI): 20MBYTES/s
Ultra SCSI (SCSI-3, Fast-20, Ultra Narrow): 20MBYTES/s
UltraIDE: 33MBYTES/s
Wide Ultra SCSI (Fast Wide 20): 40MBYTES/s
Ultra2 SCSI: 40MBYTES/s
IEEE-1394: 100-400Mbits/s (12.5--50MBYTES/s)
Hi-Speed USB 2.0: 480Mbits/s (60MBYTES/s)
PCMCIA should be compatable to at least ultra IDE standard with 32 bit cardbus, so any drive should run at max speed.
