6.2. Disk requirements

The amount of disk required by a user depends greatly on the application, so it is hard to recommend a minimum disk size. For a system with access to a central server, 200-300 Mb of local SCSI or IDE disk is fine. For a standalone system with no access to large server, 500-600 Mb is about the minimum provided you install a stripped IRAF and Linux system. If large data sets will be processed several Gb of disk may be required. IDE is fine for small disks but SCSI is recommended (in some cases required) for large disks. Modern PCs can have very respectable data transfer rates and they can be very effective for serious image processing applications that required workstations or servers not long ago.
