в настройках раида(ctrl+i) поставил страйп из двух ssd на 120gb
должен получиться один винт на 223гб

но в убунту они определяются как два отдельных диска по 111гб:

подскажите как с раидом работать?

miksoft,

mdadm - уже пройденный этап - большие нагрузки на процессор при записи маленьких файлов и скорость медленнее

вот ооотлично, спасибо огромное netwind
