SanDisk today introduced its latest solid state drive (SSD) products. The SanDisk SSD G4 serves as a drop-in replacement for hard disk drives (HDD) in notebooks; while the SanDisk SSD P4, the successor to the pSSD modular drive.

SanDisk SSD P4 and SanDisk SSD G4 offer up to 128 gigabytes (GB) and 256GB of storage respectively, double the capacities of the company?s previous SSD offerings. The drives are available in various compact form factors, which SanDisk can customize according to manufacturers? specification. The SSDs use SanDisk?s 32-nanometer (nm) multi-level cell (MLC) process technology.

SanDisk SSD G4 features a sequential read/write speeds of up to 220 and 160MB/sec, a Long-term Data Endurance (LDE) of 160 terabytes written (TBW) for a 256GB drive, sufficient for over 10 years of PC usage. In additon to accelerate performance and extend the drive?s endurance, the SSD G4 uses ExtremeFFS, a page-based algorithm that increases random write speeds and efficiency.

SanDisk SSD P4 is available in capacities ranging from 8GB to 128GB. The drive is available in various form factors that include a new ultra-small variant of the mSATA module, mSATA mini, with dimensions of 26.80 x 30.00 x 3.4 mm.

SanDisk AFM implementation for SanDisk SSD P4 uses nCache acceleration technology, a large non-volatile write cache technology that boosts burst random write performance to shorten boot times, help prevent "stalling" and "hiccups," and increase system responsiveness. The SanDisk SSD P4 offers burst random 4KB performance of up to 600 IOPS.

SanDisk SSD P4 can be used in small devices such as netbooks, smartbooks, tablet computers and ultra-thin notebooks, in addition to POS terminals, Set Top Boxes (STBs), printers and other devices that use embedded flash.

The SanDisk SSD G4 and SanDisk SSD P4 are currently being evaluated by SanDisk's top tier OEMs. High-volume production of the drives is expected in the Q3 2010
