Cassandra and Solid State Drives.

Cassandra was built for spinning disks, but actually works well with SSDs. Interesting detailed discussion including wear levelling.

Intel doubles capacity, drops price in refresh of popular SSD line

leave a comment »

Solid-State Drive 320 series offers up to 30% drop in price; capacities increased by up to triple that of X25-M drives

With the 320 Series, Intel has added native 128-bit AES encryption on the drives, which protects data while at rest on the NAND flash memory.

For data resiliency, Intel also included surplus NAND flash chips on the drive’s board over and above the usable capacity. If the SSD’s controller detects a potential chip failure, it automatically migrates data to the spare capacity.

Intel has also included small capacitors in its latest SSD, so that in the event of a power loss, data writes in progress to the NAND flash memory will be completed.

Intel unveils next gen SSDs with 6Gbit/sec throughput:

New 510 SSD series takes advantage of high-speed SATA bus interfaces on new Intel Core platforms.

Supporting data transfers of up to 500MB/sec, the Intel SSD 510 doubles the sequential read speeds and more than triples the sequential write speeds of Intel’s SATA 2.0 SSDs. The drives offer sequential write speeds of up to 315MB/sec.

SSD firmware destroys digital evidence, researchers find

SSD firmware destroys digital evidence, researchers find:

A technology built into many new solid state drives (SSDs) to improve their storage efficiency could inadvertently be making forensic analysis at a later date by police forces and intelligence agencies almost impossible to carry out to legally safe standards, researchers have discovered.
