Мой основной системник с одним винтом wd caviar blue wd5000aaks. Решил повысить надежность - докупить такой же и мигрировать на софтовый raid1. Точно таких же новых не продают, но есть похожий wd5000aakx. Смотрел доки на сайте wd - отличия в энергопотреблении (aaks кушает меньше) и интерфейсе aaks - sata2, aakx - sata3. Будете отговаривать от рэйда на таких винтах, а не специализированных (hitachi Ultrastar, WD RE, Seagate Constellation)? Позабавил тот факт, что в старом мануале на wd написано
Desktop / Consumer RAID Environments - WD Caviar Blue Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 / RAID-1).
И ниже «Business Critical RAID Environments – WD Caviar Blue Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WD’s Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like enhanced RAFF technology and thermal extended burn-in testing.»
В новом мануале мануале на wd написано

Это типа им же надо линейку red продвигать...
