- People also askSome of the advantages of using NCQ supported hard drives are: Will I notice a big performance increase when using a NCQ supported hard drive? Each hard drive model will have its own product specification which you should use to determine performance.Without NCQ, the drive would process and complete each command one at a time in the order in which it was received. NCQ Benefits: NCQ is a feature that is designed into the Serial ATA interface. To take advantage of NCQ, both the host controller/chipset and hard drive need to support the feature.sata-io.orgWyomingKnott : 90% certainty: If you have an SATA device on an SATA port set to AHCI mode, NCQ is enabled. It's a firmware ability of the drive itself. OTOH, from Wikipedia: For NCQ to be enabled, it must be supported and enabled in the SATA host bus adapter and in the hard drive itself.forums.tomshardware.comTCQ was introduced with SCSI2 and also adopted by ATA-4 standard (a.k.a. ATA/100), however only a very few ATA/100 hard drives adopted it (while it is very common to be found on SCSI hard drives). TCQ is targeted to server- and enterprise-level hard disk drives.hardwaresecrets.com
