SanDisk today expanded its Lightning Enterprise Flash Drive (EFD) family with six new 2.5-inch 6Gb SAS (6 gigabits per second Serial Attached SCSI) models.
The Lightning products are part of the new Enterprise Storage Solutions (ESS)
division that SanDisk created following its recent acquisition of Pliant
The new drives include three SLC (single-level cell) flash drives with
capacities of 100 gigabytes (GB), 200GB and 400GB; and three MLC (multi-level
cell) flash drives with capacities of 200GB, 400GB and 800GB. SanDisk also
confirmed today that HP has qualified and integrated the new Lightning 6Gb SAS
drives into its HP Qualified storage drive offerings.
SLC- and MLC-based models feature a new Single Firmware Binary technology that
reduces Sandisk's customer qualification time and speeds time-to-market. These
models feature Write Through Logging (WTL) technology, a solution that delivers
high performance at low queue depths to avoid volatility that would otherwise
require battery back-up or supercapacitors for protection.
SanDisk's enterprise-class Lightning products are integrated into HP Qualified
storage drives and available on HP ProLiant servers.
SanDisk Lightning products are available in a 2.5-inch and 3.5-inch standard
form factor with capacities ranging from 100GB to 800GB. The new drives are
designed to integrate into existing SAS enterprise storage and server systems
without the need for modifications to existing applications, operating systems
SanDisk Lightning EFDs Feature:
