Kioxia's proprietary 1st Generation XL-Flash is essentially single-level cell (SLC) NAND spread over 16 planes, whereas 2nd Generation XL-Flash is multi-level cell (MLC) flash memory spread over a higher number of planes, which by definition offers lower latency and higher parallelism for read/write operations

I’d assume the intention was to state that the MLC version would still offer lower latency despite the move from SLC to MLC?

I understand how more planes improve parallelism, but how does that improve latency?

The performance on XL-Flash was the closest anything has come to matching Optane, but it didn't really appear in many devices. I'm really curious how MLC based is going to compare as it shouldn't be anywhere near as good. If it turns out to be close to as good as the SLC version was I hope it gets more market penetration.
