Many computer systems have a memory hierarchy consisting of processor registers, on-die SRAM caches, external caches, DRAM, paging systems and virtual memory or swap space on a hard drive. This entire pool of memory may be referred to as "RAM" by many developers, even though the various subsystems can have very different access times ...
RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel, it is generally simpler to access a RAM drive through a virtual device ...
Today the term external storage most commonly applies to those storage devices external to a personal computer. [5] The terms refer to any storage external to the computer. Storage as distinct from memory in the early days of computing was always external to the computer as for example in the punched card devices and media. Today storage ...
2.5-inch hard disk drives often consume less power than larger ones. [12] [13] Low capacity solid-state drives have no moving parts and consume less power than hard disks. [14] [15] [16] Also, memory may use more power than hard disks. [16] Large caches, which are used to avoid hitting the memory wall, may also consume a large amount of power.
RAM drive software allows part of a computer's RAM (memory) to be seen as if it were a disk drive, with volume name and, if supported by the operating system, drive letter. A RAM drive has much faster read and write access than a hard drive with rotating platters, and is volatile, being destroyed with its contents when a computer is shut down ...
USB 2.0 and faster flash drives have faster random access times: typically around 1 ms, compared to 12 ms for mainstream desktop hard drives. [18] On laptop computers, the performance shifts more in favor of flash memory when laptop memory is more expensive than desktop memory; many laptops also have relatively slow 4200 rpm and 5400 rpm hard ...
