Driver name: sata_nv. Summary: No TCQ/NCQ in early chipsets. NCQ support added in later chipsets. Looks like a PATA controller, but with full SATA control including hotplug and PM. Update: NVIDIA has provided information (under NDA) that permits implementation of NCQ support, and a sample Linux implementation (patch) as well. Unfortunately, the ...

Apr 13, 2006 · Does NCQ is supported in linux? I'd like to bye Promise SATA300 TX2 plus controller and two NCQ-capable hdd's for software RAID0. Card support NCQ. Will it works on linux ? If both hdd and controller support NCq - is it enough for NCQ or there must be support by software drive also?

SATA 1.5Gb/s and SATA 3.0Gb/s speed negotiation when Tx OON signaling is selected Supports device hot-plugging Support power management features including automatic Partial to Slumber transition Internal DMA Engine for Command and Data Transactions Supports hardware-assisted Native Command Queuing (NCQ) for up to 32-entries

Linux NCQ (SATA native command queueing) support is enabled automatically, if your SATA drive supports it. At boot, you will see a line in dmesg (or kernel log) like ata2.00: ATA-7, max UDMA/133, 321672960 sectors: LBA48 NCQ (depth 31/32)
https://wiki.archlinux.org/index.php/AHCI
AHCI (Advanced Host Controller Interface) is the native work mode for SATA drives. AHCI has two main benefits: support for hot pluggable SATA drives (mimicking USB drives' behavior) and Native Command Queuing (NCQ). It has been present in the Linux kernel since version 2.6.19 and will be loaded automatically in current Arch kernel.

Linux still reaches 180 MiB/s. But then I had another idea: The Linux driver does not use transfers of 32 MiB chunks. The kernel buffer is much smaller, especially if NCQ with 32 queues is enabled (32 queues * 32 MiB => 1 GiB AHCI buffer). So I tested my SATA controller with 256 KiB transfers and voilà, it's possible to reach 185 MiB/s.
https://en.wikipedia.org/wiki/Native_Command_Queuing
In computing, Native Command Queuing (NCQ) is an extension of the Serial ATA protocol allowing hard disk drives to internally optimize the order in which received read and write commands are executed. This can reduce the amount of unnecessary drive head movement, resulting in increased performance (and slightly decreased wear of the drive) for workloads where multiple simultaneous read/write ...
