SimpleTech Zeus Ultra 2.1.3Flash Memory, 2.1.3.1Storage Capacity

Functional Description Zeus SSD Functional Blocks

2.1.3Flash Memory

The Zeus SSD’s local storage subsystem uses Single-Level Cell (SLC) NAND, non- volatile flash memory. Having only two states and one bit of data stored, SLC NAND flash control logic on the SSD is able to conserve energy when managing the electrical charge during operations.

2.1.3.1Storage Capacity

Table 5 on page 18, provides a representative list of the various capacities in which SimpleTech’s Zeus SSDs are available, along with associated LBA (Logical Bit Addressing) and CHS (Cylinder, Head, Sector) information.
