A 500 GB Western Digital hard disk drive with a 16 MB buffer. In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is ...
A major feature of the LTE Elite series was the integration of the AC adapter into the main body of the laptop. Instead of a connector for DC input, the laptop takes a standard "figure-8" connector for AC power. This eliminates the need for an external power brick and was the first time this approach had been done in a notebook-sized computer.
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 ...
Originally, solid state drives were shaped and mounted in the computer like hard drives. [39] In contrast, memory cards (such as Secure Digital (SD), CompactFlash (CF), and many others) were originally designed for digital cameras and later found their way into cell phones, gaming devices, GPS units, etc. Most memory cards are physically ...
A host adapter, host controller or host bus adapter (HBA) is a circuit board or device which allows peripheral devices (usually internal) to interface with a computer. [6] [3] Host bus adapters are used to connect hard drives, networks, and USB peripherals.
FlashPath adapters were sold both branded by SmartDisk, and as OEM devices under other brand names. FlashPath is hardware compatible with all standard 3.5" High-Density Floppy disk drives, but is not a drop-in replacement for real floppy disks. A special software device driver must be installed on the computer that is to access data via ...
Hot-swapping a hard drive in a storage server. Hot swapping is the replacement or addition of components to a computer system without stopping, shutting down, or rebooting the system; [1] hot plugging describes the addition of components only. [2]
These models can have the hard disk replaced by a standard 2.5" SSD. The adapter in the optical bay expects a 12.7 mm high 2.5" drive. At least some 2.5" SSD drives (such as the Intel X-25e) are 9 mm models. Proper fitting requires a shim (a piece of cardboard about 4 mm thick cut to the shape of the drive will do).
