iNAND Extreme

Today at MWC Shanghai, SanDisk announced a follow-up to their iNAND 7132 eMMC solution, the iNAND 7232. For those that are unfamiliar with the iNAND 7132, I would refer to our previous coverage on that storage solution. At a high level, the real importance of that product launch was that SanDisk was able to use TLC NAND to provide relatively low-cost storage with high performance using SLC caching much like their consumer SSDs. Peak sequential reads on the earlier 7132 series could reach 280 MB/s, and peak sequential writes also reached 125 MB/s on an eMMC 5.0 HS400 interface. There were 16, 32, and 64 GB SKUs which didn’t do much to push the bar in terms of on-device storage, but there are some...
