HP 1GB FBWC SMART ARRAY PSERIES 631679-S21 Form factor: 240The Flash Backed Write Cache (FBWC) uses NAND 6 flash devices to retain cache data and super capacitors (super caps) instead of batteries to provide power during a power loss. The FBWC offers significant advantages over the HP Battery Backed Write Cache (BBWC) system. Since the FBWC writes the contents of memory to flash devices, there is no longer a 48 hour battery life limitation and the data will be posted to the disk drive on the next power up.
