Samsung cranks up the speeds of its solid-state drives

Solid-state disks (SSDs) are seen as the next plateau for mobile computing. Companies like Alienware and Dell offer the high-performance drives in their notebook computers and end-users can add SSDs to their own notebooks thanks to online retailers like Newegg.

Samsung first starting making waves in the SSD arena with its 32GB drive in March 2006 and followed up with a faster 64GB unit in June of 2007. Today, Samsung is once again stepping up its efforts in the SSD arena.

The company has announced a new generation of 64GB SSDs which use 8Gb, 50nm single-level-cell (SLC) flash memory chips. The drives, which will be available in 1.8" and 2.5" form-factors, also feature a new SATA II interface for faster performance.

The faster chips and SATA II interface gives the new SSDs sequential write speeds of 100MB/sec and sequential reads of 120MB/sec. These numbers completely obliterate the previous Samsung 64GB offering which is rated at 45MB/sec write and 65MB/sec read. Samsung's first-generation 32GB SSD is rated for 30MB/sec writes and 53MB/sec reads.

"The 64GB SATA II SSD is based on Samsung’s cutting-edge NAND technology with dramatically improved performance specs that are taking system performance to a whole new level of efficiency," stated Samsung director of NAND flash marketing Jim Elliott.

Samsung's new SSDs also now compare favorably with Mtron's family of SSDs which are available in 2.5" and 3.5" form-factors. Those drives feature write speeds of 90MB/sec and read speeds of 120MB/sec.

Samsung is currently sampling the new SATA II SSDs and production examples should follow in early 2008.

Some areas are more prone to change, for example the file index. Even accessing it will modify the "last accessed date" (at least under NTFS).

USB thumb drives uses FAT or FAT32 file system so they work great on all OSes. now SSDs, your correct.

The wear leveling algorithm will transparently re-map these sectors to different locations on the physical chips. This is kind of similar to how IDE HDDs remap sectors when a bad sector is detected by the drive.
