  2. NVM Express - Wikipedia

    en.wikipedia.org/wiki/NVM_Express

    Architecturally, the logic for NVMe is physically stored within and executed by the NVMe controller chip that is physically co-located with the storage media, usually an SSD. Version changes for NVMe, e.g., 1.3 to 1.4, are incorporated within the storage media, and do not affect PCIe-compatible components such as motherboards and CPUs.

  3. Trim (computing) - Wikipedia

    en.wikipedia.org/wiki/Trim_(computing)

    The TRIM command enables an operating system to notify the SSD of pages which no longer contain valid data. For a file deletion operation, the operating system will mark the file's sectors as free for new data, then send a TRIM command to the SSD. After trimming, the SSD will not preserve any contents of the block when writing new data to a ...

  4. Thin provisioning - Wikipedia

    en.wikipedia.org/wiki/Thin_provisioning

    Thin provisioning, in a shared-storage environment, provides a method for optimizing utilization of available storage. It relies on on-demand allocation of blocks of data versus the traditional method of allocating all the blocks in advance.

  5. U.2 - Wikipedia

    en.wikipedia.org/wiki/U.2

    U.3 (SFF-TA-1001) is built on the U.2 spec and uses the same SFF-8639 connector. A single "tri-mode" (PCIe/SATA/SAS) backplane receptacle can handle all three types of connections; the controller automatically detects the type of connection used. This is unlike U.2, where users need to use separate controllers for SATA/SAS and NVMe.

    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] Reviews measured high performance with these MLC-based drives.

  7. PCI configuration space - Wikipedia

    en.wikipedia.org/wiki/PCI_configuration_space

    One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...

    en.wikipedia.org/wiki/Solid-state_drive

    NVM Express (NVMe): A modern interface designed specifically for SSDs, NVMe takes full advantage of the parallelism in SSDs, providing significantly lower latency and higher throughput than AHCI. [97] An M.2 (2242) solid-state-drive (SSD) connected into USB 3.0 adapter and connected to computer Mushkin Ventura, A USB that has an SSD inside

  9. Solid-state storage - Wikipedia

    en.wikipedia.org/wiki/Solid-state_storage

    A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts. [4]
