PerformanceDue to the lower complexity in managing SLC flash, the write performance for SLC at the IC level is typically twice as fast. With controller multiplexing this can be reduced, but this accounts for the main delta in read speed versus write speed in retail flash products today.
Endurance3-Bit MLC technology (a.k.a. TLC) has an exponentially lower number of program/erase cycles. SLC technology, targeting embedded and mission critical applications, will continue to maintain an emphasis on endurance and reliability.
