Hitachi's Enterprise MLC SSDs

Hitachi GST launches an enterprise multilevel cell (MLC) NAND  Flash SSD series, the Ultrastar SSD400M, coming in 200GB and 400GB capities, with a 6Gbp/s SAS interface. 

The series makes use of Hitachi GST's SLC technology (part of its joint development program with Intel) giving the drives enterprise-class capabilities. 

The 400GB version handles up to 7.3 petabytes of data writes over its lifetime. 

Hitachi says it also features a mean time between failure rating of 2M hours-- comparable to the company's own SLC Flash SSDs.

Whiptail Accelerates Virtual Desktops

Whiptail aims for the virtual desktop market with its XLR8r, a SSD-based SAN which the company calls VDI's next evolutionary step. 

The XLR8r is a purpose-built 2U appliance designed to optimise virtual desktop deployment, with 1 XLR8r able to handle up to 6000 users and 250000 IOPS (as much as x8 fully loaded HDD racks). 

It has power consumption of less than 200W, with 0.1ms latency and capacities of up to 12TB. Gigabit Ethernet (x2) interfaces come as standard, with optional quad or dual 10 GB/s ethernet, 1 Gb/s ethernet, 40 Gb/s Read more...

Flash Memory Gets Ever Smaller

SanDisk and Toshiba's developments in NAND flash memory get even smaller-- producing a 64Gb X2-based monolithic chip with 19nm technology.

The 19nm 64Gb X2 device will see sampling this quarter, before high-volume production following Q2 2011. At that time Sandisk will also start producing X3 products with the 19nm technology.

The process is the company's most advanced yet, and should allow for smaller high capacity removable and embedded storage devices for use in all sorts of mobile devices, from tablets to mobile phones.
