hard disk drive and PMC-Sierra's QuadSMX 3G is a critical step in delivering advanced storage products to the market.
accommodates use of Serial ATA
with external storage devices.
With NCQ, Serial ATA
devices can provide sophisticated command reordering optimizations for multi-threaded applications previously only available with higher-end storage interfaces.
It will also utilize the Serial ATA
development work on smaller cable connectors, providing customers a downstream compatibility with desktop class ATA
The major driving factor of D2D backup is the price per MB and the performance of ATA
drives when utilizing 32KB block transfers, not necessarily the ATA
/100 and ATA
/133, the current Parallel ATA
interfaces, offer peak transfer rates of only 100MB/sec and 133MB/sec, respectively.
The 200GB SP2014N ($130) and the 250GB SP2514N ($150) feature an Ultra ATA
-133 Interface, Fluid Dynamic Bearing Spindle Motor Technology, ATA
Security Mode, ATA
host Protected Area, and an ATA
there's a very short maximum allowable cable length between the controller and drives of 18 inches, meaning that ATA
interfaces are limited to "inside the box" RAID applications.
interface, designed to be cheap, has some serious problems.
Test suites cover over 10 different categories to verify all ATA
commands, reset, power modes under normal and error conditions
Use of an 80-conductor cable also has enabled Quantum to double the Ultra ATA
burst data transfer rate--simply by streamlining data management within the drive.
Much of this shift reflected the growth of ATA
and, to a lesser extent, Southwest during this period.
