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
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
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
