In today's NAND implementations, the host controller must assume responsibility for all NAND management functions, including block management, wear leveling
, and ECC.
f) Preemptive Wear Leveling
(PWL) - The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications.
As a result of wear leveling
and write combining, the performance of SSDs degrades with use.
Other SMLC-based products will follow and will be priced somewhere between SLC and MLC cost per gigabyte, a Fusion-io spokeswoman said.<p>The SMLC products have a PCI Express-based form factor and chip-level redundancy, as well as RAID protection, wear leveling
and error-correction firmware.
Its ECC protection combined with using a proprietary static wear leveling
technology provides up to four million read/writes cycles per cell--one of the highest read/write endurances available.
* Improved data integrity via static wear leveling
, Reed-Solomon ECC and bad block managenrent.
"With fault tolerance, optional LevelX[TM] flash wear leveling
, and now support for exFAT, our FileX file management system gives embedded developers the tools they need to meet this demand."
* Supports CPRM, ECC, wear leveling
technologies and etc.
Despite their extra-small dimensions, the N8S750 and MSA340 come equipped with advanced features such as TRIM and NCQ support, built-in ECC and wear leveling
, intelligent block management, support for enhanced S.M.A.R.T.
Combination of SLC memory with the TDK flash memory controller GBDriver RS3 implementing the TDK "SMART SWAP" algorithm for global static wear leveling
results in an SSD device with long life span.
Based on the Hyperstone 32 Bit RISC core, including instruction set extensions optimized for Flash handling, this family of products offers safe power fail handling, error detection and correction, optimal wear leveling
that involves all physical blocks including the ones containing static data.
