TDK 64GB SSD with Micro SATA Interface

TDK Japan launched the “HS1” series, a line of 1.8-inch solid state disks (SSD) with the Micro SATA interface, targeting notebook computers and industrial devices. The TDK HS1 series comes in three models with storage capacities of 16, 32 and 64 Gbytes, respectively. The product uses SLC (single-level cell) NAND flash memory. Burst performance is 100MBps reading and 50MBps writing. To accelerate the writing speed, the TDH HS1 disk has a four-channel bus, which extended the standard one- or two-channel bus, between the controller LSI and the NAND flash memory.

The encryption method used in the disk is 128-bit AES. The disk also has a function to detect and correct errors up to 7 bits. The combination of MLC memory and the controller IC provides the disc a rewrite life of 10 years (when operated 24 hours a day, 365 days a year), according to TDK. The TDK HS1 disks are now available for volume shipment at sample prices of ¥200,000 (1,902) for a 64-Gbyte model, ¥150,000 ($1438) for a 32-Gbyte model and ¥90,000 ($865) for a 16-Gbyte model.
