TLC flash has three types of pages to accommodate the three bits in each TLC physical cell exhibiting very different program latencies, LSB (fast), CSB (medium), and MSB (slow). Conventional TLC SSD designs on page allocation to write requests do not take page types and their latency difference into consideration, missing on an important opportunity to exploit the potentials of fast writes.
