Block I/O is the basic mechanism for DISK access using the SCSI
protocol as the command set. Block I/O is fast and data can be
transmitted in various block sizes like 2K, 4K, 8K, 16K, 64K, 128K,
etc. Block I/O can be done over various transports. Parallel SCSI
cables, copper fiber, optical fiber and even encapsulated and
transmitted over IP networks.
Block I/O is what is used to talk to DISKS.
File I/O is what is used to talk to FILES.
Is Block I/O necessarily a SCSI thing? I thought 'dd' command could be
used for block I/O over devices like floppy, CDROM, and IDE device?
Am I wrong?
No. My reply using that very example seems to be stuck in the queue
again though. Love this list...
