Organization. Intel. Website. www .intel .com /content /www /us /en /io /serial-ata /ahci .html. The Advanced Host Controller Interface ( AHCI) is a technical standard defined by Intel that specifies the register-level interface of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets. [ 1]
The Ultra DMA ( Ultra Direct Memory Access, UDMA) modes were the fastest method used to transfer data through the ATA hard disk interface, usually between the computer and an ATA device. UDMA succeeded Single / Multiword DMA as the interface of choice between ATA devices and the computer. There are eight different UDMA modes, ranging from 0 to ...
A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
A high-level overview of the SATA Express software architecture, which supports both legacy SATA and PCI Express storage devices, with AHCI and NVMe as the logical device interfaces [8]: 4 SATA Express interface supports both PCI Express and SATA storage devices by exposing two PCI Express 2.0 or 3.0 lanes and two SATA 3.0 (6 Gbit/s) ports ...
In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [1] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and servers. The first memory modules were proprietary designs that were specific ...
DevSlp. DevSlp or DevSleep (sometimes referred to as device sleep or SATA DEVSLP) is a feature in some SATA devices which allows them to go into a low power "device sleep" mode when sent the appropriate signal, which uses one or two orders of magnitude less power than a traditional idle (about 5 mW, [1] but some drives can get as low as 2.5 mW ...
Port multiplier. A SATA 2.0 (3 Gbit/s) PCI Express ×1 expansion card, having two built-in SATA port multipliers (square chips to the left and right of the middle of PCB) that "splice" card chipset's two SATA ports into a total of eight ports. A Serial ATA port multiplier ( SATA PM) is a device that allows multiple SATA devices to be connected ...
List of Intel SSDs. An Intel X25-M SSD. Intel P3608 NVMe flash SSD, PCI-E add-in card. An Intel mSATA SSD. On September 8, 2008, Intel began shipping its first mainstream solid-state drives (SSDs), the X18-M and X25-M with 80 GB and 160 GB storage capacities. [ 1]
