WebAddonics Dual CF-IDE HDD Adapter with 8GB SanDisk Extreme IV CompactFlash. Changing your HDD for a CF boot drive (CompactFlash card on CF-PATA/SATA adapter) is an alternative to using SSD to boost the performance. This is primarily done by ThinkPad X40, X41 and X41 Tablet series owners due to the extremely slow speed of 1.8" HDD. WebThe NAND Flash array is grouped into a series of blocks, which are the smallest erasable entities in a NAND Flash device. A NAND Flash block is 128KB. Erasing a block se ts all bits to 1 (and all bytes to FFh). Programming is necessary to change erased bits from 1 to 0. The smallest entity that can be programmed is a byte.

On flash memory, however, the minimum size of a read is typically much smaller than a minimum write. In essence, the sectors are numbered 0, 1, 2, etc. up to (N-1), where N is the number of sectors on the disk.
