Common examples of this include Raw video, weather data, and backups typically. These RAID drives are constructed with vibration resistance on account of the fact that they're ceaselessly utilized in RAID enclosures consisting of many drives. Tape drives are a type of secondary storage used by companies to retailer extremely massive quantities of knowledge at a low price. They are comparatively cheap compared to different types of storage. However, they are extraordinarily sluggish (you wouldn’t need to should entry tape drives frequently).<br>
