SanDisk is one of the big players in the NAND flash market, and it cannot pass up an opportunity to cater to the exploding netbook market and need to replace hard disk drives (HDDs) with solid state drive (SSDs).
SSDs today are dominated by two different types of NAND flash. The more expensive drives use faster, longer-lasting single level cell (SLC) memory while multi-level cell (MLC) flash can be found in more mainstream SSD offerings from the likes of OCZ and Super Talent. MLC-based SSDs don't often offer the write speeds or cell endurance of SLC-bases SSDs, but their price/GB is much more competitive.
Given that SanDisk is trying to target the budget netbook market with its latest product, the Gen 2 pSSD, it has opted for the more cost effective MLC solution. The new Gen 2 pSSD drives are built using 43nm technology and are available in 8GB, 16GB, 32GB, and 64GB capacities.
"Netbooks represent the fastest growing PC segment in 2009 and 2010 yet widespread adoption of SSDs in netbooks has been limited by speed, capacity and cost constraints," said SanDisk SSD general manager Richard Heye. "With the significant improvements in performance, capacity and low pricing, these SSDs are a perfect fit for the exploding netbook market."
SanDisk's second generation pSSDs use a SATA interface instead of the older PATA interface for faster transfer speeds. They will also be priced competitively with competing 2.5" HDD offerings according to SanDisk.
SanDisk’s new SSDs will first be made available in February of this year.
