Description:

The other half of the SU750’s potential problem is that there are only two NAND channels for bandwidth to handle all those FTL processes and move data around while juggling in host requests. Which means under heavy workloads, things can get a bit congested. This is half the channels that other mainstream SATA SSD controllers have. Just as DRAM can help improve the performance in an SSD, more NAND channels enable faster performance as well. With more channels, there is more opportunity for striping, interleaving, and pipelining optimization. However, these come at the cost of increased power consumption and die size and thus affects production cost, which is why the SU750 features just two.
