provides a number of advanced capabilities such as command reordering, first-party DMA, interrupt aggregation and race-free status return for multi-user system builders needing enhanced system-level performance for applications with transactional workloads.
It costs about $2,000 to put an NCQ
through training for one year, said Chirita.
More specifically, NCQ
increases performance and disc drive life by allowing the drive to internally optimize the execution order of workloads or commands.
The hard drive on the left, with NCQ
, can execute four commands (A, B, C, and D) with one and a quarter complete rotations due to proper ordering of the operations.
Native Command Queuing Support: NCQ
is a widely anticipated feature introduced in the Serial ATA II extension to the Serial ATA 1.
6 Controller to provide enhanced NCQ
for isochronous data transfers and queue management," said Aviv Malinovitch, Vice President, Operations at CEVA.
The Momentus 750GB drive also features a SATA 3Gb/s with NCQ
interface, 16MB cache with silent acoustics and low power consumption.
Management feature that helps optimize performance by enabling host processing and management of outstanding NCQ
The Protocol Test Suite is for validation the SATA/ATA command protocol including NCQ
and DSM TRIM commands.
0Gbps interface, a 175MB/s maximum media transfer rate, and NCQ
for random I/O performance.
