Most classic macs use a harddisk drive as their main mass storage medium. The majority of 68k Macs uses SCSI harddisk drives of a kind not in production any more. There are several options to replace a defective SCSI harddisk drive. Here you will find some suggestions. The article needs to be reformatted, please help.

The choice should depend on the use to be expected for the device. - For frequent use with heavy writing load, where writing access performace is of importance, have a SCSI-IDE converter in combination with a new silent IDE harddisk (available in 2.5" and 3.5" varieties). - If your system has no fan and you need it to be even quieter than a modern silent harddisk but with top performance, have a solid state disk or an industrial grade dual CF adaptor with two CF cards in striping RAID mode (level 0). - In any other case a recent CF card in an appropriate adaptor should do well in a vintage machine. (Do not use this drive for virtual memory.) A Micro Drive (with the CF form factor) for use as a replacement for a standard hdd would give you the benefits of a small footprint, low power consumption and fast writing access. It would combine the disadvantages of both CF cards (less reliable) and usual harddisk drives (moving parts), also. - If price matters (as it usually does), you might consider an external SCSI enlosure with a long cable, hiding away the drive in a place where it is allowed to be noisy, and use up used server harddisks (SCSI). You might have to throw in a few extra bucks for a recent SCSI-a-lot-pins to standard SCSI adaptor, but gain a cheap supply for high speed drives. This especially applies to people with access to server farms, where usable drives get swapped for new ones based on a fixed schedule. - And, a more hypothetical case, if the price should not matter at all, have an UPS buffered RAM-disk and stream the data to a NAS.
