This new generation of MLC flash memory SSDs include improvements in the flash cells themselves combined with NAND flash memory management in the controller to achieve much better flash cell endurance.
SSDs using flash memory consume considerably less energy when they are operating compared to HDDs.
FORBES: Seagate Discontinuing 7,200 RPM Drives--A Focus on Capacity?
Caching frequently used content on SSDs or flash memory is becoming a common approach to accelerate performance for most storage system suppliers.
SSDs using NAND flash memory are capable of very fast read and write speeds and thus can make immediate use of such fast interfaces (whereas it takes many SAS HDDs working together to result in data rates even approaching there speeds).
Toshiba (one of the major producers of flash memory) announced three new SSDs in its eSSD series.
Built from the highest quality components, it employs synchronous NAND flash technology capable of more than twice the performance of the average asynchronous SSDs, delivering the best speed and performance available in flash-based storage for both uncompressed and compressed files.
ENGADGET: Baseline Modbook Pro gets its RAM, storage and screen sensitivity doubled, stays at $3,500
Intel is taking advantage of the good reputation it has developed with its SSDs to continue its campaign to bring NAND flash in the form of an SSD into all PC applications.
Commonly called SSDs or Solid State Disks, these devices put NAND flash into computing environments that typically would use hard disk drives, or HDDs.
The Semiconductor Business sustained profitability in the quarter, amid weak market demand, thanks to a mix of high-margin products such as servers and Solid State Drives (SSDs) coupled with differentiated 20-nanometer class NAND flash chips.
ENGADGET: Samsung reports $8.27 billion in profits for Q4 2012 HD
Drobo and other companies announced that they are including SSDs in their storage products as a caching tier showing that flash-based cache is moving into the SMB market.
By reducing flash cell wear it may be possible to make TLC (three level cell flash) more useful and to reduce the intensive wear leveling common in SSDs today.
The SSDs include Intel High Endurance Technology and uses 25-nm MLC flash memory.
Demand for high-performance 3-bit MLC NAND flash and 128Gb high storage capacities has been rapidly increasing, driving the adoption of SSDs with more than 250GB data storage, led by the Samsung SSD 840 Series.
When properly engineered, SSDs are now at least as reliable as traditional spinning hard drives (although cheap flash can still be frustratingly unreliable).
FORBES: SSD Flash Storage is Transforming Tomorrow's Business
This will require 105 Exabytes of flash memory by 2020 but the total storage demand for computers will require more HDD units than SSDs.
All three argued that, in order for SSDs to replace HDDs in PCs, hundreds of billions of dollars would need to be invested in flash manufacturing capacity, and that such funding was quite simply unavailable.
