Data center operators are optimizing compute and storage space, with Meta exploring QLC flash as a balance between costly TLC solutions and traditional HDDs. While HDDs struggle with decreasing bandwidth despite growing capacity, TLC flash efficiently manages frequently used data. QLC flash is gaining attention due to its suitability for less demanding workloads at a lower cost than TLC, as advancements in 2Tb NAND flash chips improve density. Collaboration with Pure Storage to explore various QLC solutions may pave the way for broader adoption, although Meta remains cautious about its price competitiveness for widespread use.
"While today QLC is lower in cost than TLC, it is not yet price competitive enough for a broader deployment," Meta notes, highlighting the cautious approach towards QLC.
"We expect QLC SSD density will scale much higher than TLC SSD density in the near-term and long-term," suggests Meta, indicating optimism about QLC's future potential.
