Toshiba announced it's working on 7mm thick solid state disks with 19nm MLC NAND. These disks are designed for use in ultrabooks, compact laptops, and All-in-One PCs, they will enter mass production in August and will be released in 64GB, 128GB, 256GB and 512GB capacities. Full performance details aren't available yet, but Toshiba mentions these disks will deliver read speeds of up to 524MB/s and write speeds as high as 461MB/s. Further details at Bit Tech.
As well as the latest 19nm multi-level cell NAND flash components, the drivers are tipped to include Toshiba's proprietary Quadruple Swing-By Code (QSBC) technology which the company claims protects more efficiently against read errors than traditional error correcting code (ECC) technologies alone.
Interestingly, the latest Toshiba drives will also include a system to protect against data corruption following unexpected power loss, along with a read-only mode which allows for data recovery in the event that the device becomes too damaged to operate normally.
If Toshiba's focus on ultra-portable electronics wasn't clear from the svelte dimensions of the 2.5in drives, the power characteristics would be a dead giveaway: Toshiba is keen to point out that the use of improved advanced power management (APM) capabilities mean a measured power draw of just 0.1W when running the MobileMark 2007 Workload test.
