What Happens When ECC Fails to Correct SSD Data?

What Happens When ECC Fails to Correct SSD Data? Grandma falls out of the family photo. By Kent Smith of LSI Most users have no idea that reading electronic information from a data storage medium like a hard disk drive (HDD) or solid state drive (SSD) is plagued with read errors. For this reason error correction …

AIS: The Problem with Multicore Processors

AIS: The Problem with Multicore Processors By Troy Bailey of LSI The problem with multicore processors isn’t that they have a lot of cores. I hope my IC designer colleagues don’t jump me when I say that having more than one core on a chip is a simple matter of cut and paste. The tricky …

Don’t Let SSDs Throw Away Your Gold

Don’t Let SSDs Throw Away Your Gold By Kent Smith of LSI All NAND flash-based SSDs use a process called garbage collection (GC) so the flash memory can be rewritten with fresh data, enabling the SSD to function like any other rewritable storage device. The number of rewrites (program/erase cycles) possible with NAND flash memory …

Teasing Out the Lies in SSD Benchmarking

Most consumers are skeptical when they see a manufacturer whipping out grandiose performance claims. And for good reason. The manufacturer could be stretching the truth, twisting the results, or just being downright misleading. From this distrust grew demand for 3rd-party writers to review products, test claims and provide an unbiased analysis of the device’s performance and other capabilities – as consumers would experience themselves.

How 50 Year Old Error Correction Code Gives SSD Flash Memory a Boost

For the uninitiated, low-density parity-check (LDPC) code is an error correction code (ECC) that is used to both detect and correct errors on data that is transmitted from one point to another. All ECC types include correction data, so when information is transmitted with errors, the receiver has enough information to fix the errors without having to ask the source for the data again.

Why SSDs Hate Write Amplification: Part 1

Why SSDs Hate Write Amplification: Part 1 By Kent Smith – Senior Marketing Director: LSI Flash Components Division In today’s solid state drives (SSDs), the NAND flash memory must be erased before it can store new data. In other words, data cannot be overwritten directly as it is in a hard disk drive (HDD). Instead, SSDs …
