Block Drivers (Compact 2013)
3/26/2014
Block device drivers read or write data to block devices in fixed-size blocks. Block devices do not allow you to read or write individual bytes of data. Common block sizes are 512 bytes, 1 kilobyte (KB), 2 KB, and 4 KB. Block devices are ideally suited for mass storage and persistent storage applications, such as disk drives or nonvolatile RAM disks.
Some common types of block devices are hard disks, Advanced Technology Attachment (ATA) flash memory disks in miniature cards, and memory card form factors.
To add this feature to your OS, see Block Driver Catalog Items and Sysgen Variables.
For reference information, see Block Driver Reference.
