As of July 2010[update], the highest capacity consumer HDDs are 3 TB.[17]
"Desktop HDDs" typically store between 120 GB and 2TB (although rarely above 1.5 TB of data based on US market data[18]) and rotate at 5,400 to 10,000 rpm, and have a media transfer rate of 0.5 Gbit/s or higher. (1 GB = 109 Byte; 1 Gbit/s = 109 bit/s)
Enterprise HDDs are typically used with multiple-user computers running enterprise software. Examples are:
transaction processing databases
internet infrastructure (email, webserver, e-commerce)
scientific computing software
nearline storage management software
The fastest enterprise HDDs spin at 10,000 or 15,000 rpm, and can achieve sequential media transfer speeds above 1.6 Gbit/s.[19] and a sustained transfer rate up to 1 Gbit/s.[19] Drives running at 10,000 or 15,000 rpm use smaller platters to mitigate increased power requirements (as they have less air drag) and therefore generally have lower capacity than the highest capacity desktop drives.
Enterprise drives commonly operate continuously ("24/7") in demanding environments while delivering the highest possible performance without sacrificing reliability. Maximum capacity is not the primary goal, and as a result the drives are often offered in capacities that are relatively low in relation to their cost[20].
