Late last year, Micron announced its move to SATA 3.0 and ONFI 2.1 in its consumer-oriented MLC (multi-level cell) SSDs when it introduced the C300 series. That series also represented the first SSDs made with the company's 34-nm process technology. The P300 SSDs will use SLC (single-level cell) technology, which is considered more dependable in the long term and is typically used in enterprise flash storage.
In addition to stepping up to the new manufacturing process and interface standards, the P300 includes NAND management features designed for longer life in enterprise online-transaction-processing environments. These include data path protection and automatic wear leveling, which prevents one area of the NAND array from being overused. The SSDs are designed for a useful life of at least five years, according to Micron.
Dibelius would not comment on when Micron may start using its 25-nm process in SSD products.
