Plextor joins titans of MLC flash at the 90,000 plus club

Plextor has joined OCZ and SMART in the 90,000+ club, the providers of elite MLC SSDs that exceed 90,000 random read IOPs per second. Fast single-level cell (SLC) flash is used to drive SSDs at speeds beyond 100,000 IOPS doing random reads of 4K data blocks. Multi-level cell (MLC) flash, with 2 bits per cell, is slower, shorter- …

Flash could be CHEAPER than SAS DISK? Come off it, NetApp

A NetApp pitch at the Flash Memory Summit said the cost-per-GB price trends for cheap TLC flash mean it will dip below SAS disks in 2017. TLC is triple-level cell flash which holds three bits per cell, half as much again as the standard 2-bit or MLC NAND that is used in SSDs and server flash cards. Because TLC is denser in …
