Solid-state drives: lower SATA speeds but more advanced lithographies

摘要

Intel recently unveiled its 320 series, which employs a 25-nm, 2-bit-per-cell, MLC (multilevel-cell)-NAND-flash-compatible Intel storage controller. Cost and capacity are the primary beneficiaries of this process and processor transition. Intel has added 300- and 600-Gbyte product tiers to its earlier-generation 2.5-in.-form-factor X25-M products. The 320 series also comes in a 1.8-in. form factor in 80-, 160-, and 300-Gbyte flavors. However, the Intel-proprietary controller is not yet 6-Gbps SATA (Serial Advanced Technology Attachment)-compatible, although it supports SATA II features, such as native-command queuing.
