Zeus 2.5-Inch Serial ATA Solid State Drive
Mount Time
The amount of time required to initialize and mount a Zeus SATA SSD varies according to the
operating system (Windows
the drive.
Seek Time
Unlike a magnetic rotating disk, the SSD has no read/write heads or platter. There is no seek time or
rotational latency issues. Zeus SSDs dramatically improve transaction throughput, particularly for
applications that are configured to take advantage of the characteristics of the drive.
Data Transfer Rates
The data transfer rate of the SSDs depends on the flash controller/flash memory configuration of the
drive. The scalable architecture of the drive is capable of accommodating sustained and burst data
transfer rates outlined in Table 2.
Cache Operations
The SSD is configured with 64Mbytes of usable cache. The drive will track the location of the data
stored in the cache, and will use the cache data instead or re-transferring the data from the host or
the media, if the cache contains the data needed for read or write.
A two-way set associative cache algorithm is implemented using 128Kbyte line sizes. The cache
operation is circular, and when the end of the segment is addressed, it will wrap around to the
beginning location of the segment.
The cache buffer can be accessed directly using the Write Buffer (0xE8) command. The cache is
enabled or disabled using the ATA Set Features (0xEF) command. The Read and Write cache are
both enabled by default.
