Advanced ECC

ECC Tek has invented and patented methods and apparatus for encoding and decoding Reed-Solomon codes in a parallel and pipelined fashion. This technology coupled with conventional Reed-Solomon technology can be used to create fault-tolerant hard disk drives (Two-Dimensional Reed-Solomon HDDs) and fault-tolerant solid state disks (Two-Dimensional Reed-Solomon SSDs).

Designing Ultra-High-Performance RAID Storage Systems

The following article describes at a high level a powerful way of designing ultra‑high‑performance RAID storage systems so that future RAID systems will be able to use fairly unreliable memory elements such as MLC NAND Flash chips with no loss of performance or data when numerous cells and chips fail: 2D-RS Storage Systems.

Two-Dimensional Reed-Solomon NAND Flash Solid State Disks (2D-RS SSDs)

High cost and wear-out characteristics of NAND Flash chips have limited sales of NAND Flash Solid State Disks. ECC Tek’s Two-Dimensional Reed-Solomon error-correction system solves these problems.

2D-RS SSDs should be developed into commercial products for the following reasons:

Two-Dimensional Reed-Solomon Hard Disk Drives (2D-RS HDDs)

ECC Tek proposes that some HDD Company develop a new class of disk storage products called Two-Dimensional Reed-Solomon Hard Disk Drives (2D-RS HDDs). 2D-RS HDDs would have much higher transfer rates than conventional HDDs and a variable level of automatic, built-in backup. 2D-RS HDDs would contain a number of Head-Disk Assemblies (HDAs) and a custom controller chip as components.

All of the HDAs in a 2D-RS HDD would be written and read simultaneously. The disks within all of the HDAs would be synchronized so that a 2D-RS HDD would appear to be a conventional HDD but with higher performance and automatic, built-in backup which is impossible in a conventional HDD.

To summarize, ECC Tek believes 2D-RS HDDs should be developed into commercial products for the following reasons:
