Abstract: Application data and error correction code (ECC) checkbits associated with that application data are stored in a first memory. The ECC checkbits, but not the application data, are stored in a second memory. In response to a request to read the application data from the first memory, the ECC checkbits from the first memory are also read and used to detect, and possibly correct, errors in the read application data. The ECC checkbits are further output from both the first and second memories for bit-by-bit comparison. In response to a failure of the bit-by-bit comparison, a signal indicating possible malfunction of one or the other or both of the first and second memories is generated.

Abstract: A method for execution by a computing device of a dispersed storage network (DSN) begins by receiving a data segment for dispersed storage error encoding. Prior to encoding, the method continues by determining whether to compress the data segment by predicting a first estimated processing cost (EPC) based on EPCs to dispersed storage error decode a compressed set of encoded data slices to recover a compressed data segment and EPCs to decompress the compressed data segment to recover the data segment and by predicting a second EPC based on EPCs to dispersed storage error decode the set of encoded data slices to recover the data segment. When the first EPC compares favorably to the second EPC, the method continues by compressing the data segment to produce the compressed data segment and dispersed storage error encoding the compressed data segment to produce the compressed set of encoded data slices.
