 To keep scanning times to a minimum, it is strongly recommended to use a large
 buffer size for the generic SCSI driver. From SG driver version 2.0 on, the
 maximum buffer size can be changed at program run time, and there is no restriction in size. This driver version is part of the Linux kernels from
 version 2.2.7 on. If the new SG driver is available some backends

 than 1 MB, because for large values the probability increases that the
 SG driver cannot allocate the necessary buffer(s). For ISA cards, even
 1 MB might be a too large value. For a detailed discussion of memory
