Режим AHCI работы жестких дисков SATA позволяет задействовать технологию NCQ (Native Command Queing), DIPM (Device Initiated Power Management) и другие возможности, такие как горячая замена SATA-накопителей. В общих чертах включение режима AHCI позволяет повысить скорость работы жестких дисков и SSD в системе, в основном, за счет преимуществ NCQ.
В этой инструкции — о том, как включить режим AHCI в Windows 10 уже после установки системы, если по какой-то причине переустановка с предварительно включенным в БИОС или UEFI режимом AHCI не представляется возможной, а система была установлена в режиме IDE.
Отмечу, что практически для всех современных компьютеров с предустановленной ОС данный режим уже включен, а само изменение особенно актуально для SSD накопителей и ноутбуков, так как режим AHCI позволяет повысить производительность SSD и, одновременно (хоть и незначительно) понизить энергопотребление.
И еще одна деталь: описываемые действия в теории могут привести и к нежелательным последствиям, таким как невозможность запуска ОС. А потому беритесь за них лишь в том случае, если знаете, для чего это делаете, умеете попасть в БИОС или UEFI и готовы в случае чего к исправлению непредвиденных последствий (например, путем переустановки Windows 10 с самого начала в режиме AHCI).
Узнать, включен ли режим AHCI в текущий момент, можно заглянув в настройки UEFI или БИОС (в параметрах SATA устройств) или прямо в ОС (см. скриншот ниже).
Также можно открыть свойства диска в диспетчере устройств и на вкладке Сведения посмотреть путь к экземпляру оборудования.
Если он начинается с SCSI — диск работает в режиме AHCI.
Включение AHCI с помощью редактора реестра Windows 10
Для того, чтобы задействовать работу жестких дисков или SSD нам потребуются права администратора Windows 10 и редактор реестра. Для запуска реестра нажмите клавиши Win+R на клавиатуре и введите regedit.
- Перейдите к разделу реестра HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services iaStorV, дважды кликните по параметру Start и установите его значение равным 0 (ноль).
- В соседнем разделе реестра HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services iaStorAV StartOverr >Следующий шаг — перезагрузить компьютер и войти в UEFI или БИОС. При этом первый после перезагрузки запуск Windows 10 лучше провести в безопасном режиме, а потому рекомендую заранее включить безопасный режим с помощью Win+R — msconfig на вкладке «Загрузка» (Как зайти в безопасный режим Windows 10).
Если у вас UEFI, рекомендую в данном случае сделать это через «Параметры» (Win+I) — «Обновление и безопасность» — «Восстановление» — «Особые варианты загрузки». Затем зайдите в «Устранение неполадок» — «Дополнительные параметры» — «Настройки ПО UEFI». Для систем с БИОС — используйте клавишу F2 (обычно на ноутбуках) или Delete (на ПК), чтобы зайти в настройки БИОС (Как зайти в БИОС и UEFI в Windows 10).
В UEFI или БИОС найдите в параметрах SATA выбор режима работы накопителей. Установите его в AHCI, после чего сохраните настройки и перезагрузите компьютер.
Сразу после перезагрузки ОС начнет устанавливать драйвера SATA, а по завершении вам будет предложено перезагрузить компьютер. Сделайте это: режим AHCI в Windows 10 включен. Если по какой-то причине способ не сработал, обратите внимание также на первый вариант, описанный в статье Как включить AHCI в Windows 8 (8.1) и Windows 7.
