This is the original filing date of the application which led to US Patent 3,503,060, generally accepted as the definitive hard disk drive patent. [1] The 2011Thailand floods damaged the manufacturing plants and impacted hard disk drive cost adversely between 2011 and 2013. [43] Make a list of all installed software and product keys. To make it easier to make the transition easier from an old drive to a new one, create a list of everything you need to install along with any product keys. Belarc Advisor can help with this. If you can create a full disk image, you likely won't have to worry about this though.

Information is written to and read from a platter as it rotates past devices called read-and-write heads that are positioned to operate very close to the magnetic surface, with their flying height often in the range of tens of nanometers. The read-and-write head is used to detect and modify the magnetization of the material passing immediately under it. To minimize cost and overcome failures of individual HDDs, storage systems providers rely on redundant HDD arrays. HDDs that fail are replaced on an ongoing basis. [141] [89] Market segments [ edit ] Consumer segment [ edit ] Two high-end consumer SATA 2.5-inch 10,000rpm HDDs, factory-mounted in 3.5-inch adapter frames Desktop HDDs Desktop HDDs typically have two to five internal platters, rotate at 5,400 to 10,000 rpm, and have a media transfer rate of 0.5Gbit/s or higher (1GB = 10 9 bytes; 1Gbit/s = 10 9 bit/s). Earlier (1980–1990s) drives tend to be slower in rotation speed. As of May 2019 [update], the highest-capacity desktop HDDs stored 16 TB, [142] [143] with plans to release 18 TB drives later in 2019. [144] 18 TB HDDs were released in 2020 [ citation needed]. As of 2016 [update], the typical speed of a hard drive in an average desktop computer is 7,200 RPM, whereas low-cost desktop computers may use 5,900 RPM or 5,400 RPM drives. For some time in the 2000s and early 2010s some desktop users and data centers also used 10,000 RPM drives such as Western Digital Raptor but such drives have become much rarer as of 2016 [update] and are not commonly used now, having been replaced by NAND flash-based SSDs. Mobile (laptop) HDDs Smaller than their desktop and enterprise counterparts, they tend to be slower and have lower capacity, because typically has one internal platter and were 2.5" or 1.8" physical size instead of more common for desktops 3.5" form-factor. Mobile HDDs spin at 4,200rpm, 5,200rpm, 5,400rpm, or 7,200rpm, with 5,400rpm being the most common; 7,200rpm drives tend to be more expensive and have smaller capacities, while 4,200rpm models usually have very high storage capacities. Because of smaller platter(s), mobile HDDs generally have lower capacity than their desktop counterparts. Consumer electronics HDDs The two most common form factors for modern HDDs are 3.5-inch, for desktop computers, and 2.5-inch, primarily for laptops. HDDs are connected to systems by standard interface cables such as PATA (Parallel ATA), SATA (Serial ATA), USB or SAS ( Serial Attached SCSI) cables.As the 1980s began, HDDs were a rare and very expensive additional feature in PCs, but by the late 1980s, their cost had been reduced to the point where they were standard on all but the cheapest computers. The 1.8-inch form factor is obsolete; sizes smaller than 2.5 inches have been replaced by flash memory.
