There are low-value, high-capacity RAID drives (instance: WD Crimson and Seagate IronWolf) that provide a really excessive capacity-to-price ratio for folks or businesses that need to store very large quantities of knowledge (many terabytes). Common examples of this embrace Raw video, weather data, and backups generally. These RAID drives are built with vibration resistance resulting from the truth that they're regularly utilized in RAID enclosures consisting of many drives. Tape drives are a form of secondary storage utilized by companies to retailer extremely giant amounts of data at a low price. They are comparatively low cost compared to other types of storage. Nonetheless, they're extremely gradual (you wouldn’t want to should entry tape drives ceaselessly).
