    en.wikipedia.org/wiki/Self-Monitoring,_Analysis...

    Hard disk and other storage drives are subject to failures (see hard disk drive failure) which can be classified into two basic classes: Predictable failures which result from slow processes such as mechanical wear and gradual degradation of storage surfaces. Monitoring can determine when such failures are becoming more likely.

  4. Power-on hours - Wikipedia

    en.wikipedia.org/wiki/Power-On_Hours

    Power-on hours is intended to indicate a remaining lifetime prediction for hard drives and solid state drives, generally, "the total expected life-time of a hard disk is 5 years" [3] or 43,800 hours of constant use. [4] [5] Typically, after a disk reaches 5 years of power-on time, the disk is more likely to fail.

  5. CrystalDiskMark - Wikipedia

    en.wikipedia.org/wiki/CrystalDiskMark

    CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. Based on Microsoft's MIT-licensed Diskspd tool, [2] this graphical benchmark is commonly used for testing the performance of solid-state storage. [3] [4] It works by reading and writing through the filesystem in a volume-dependent way.

  6. Hard disk drive performance characteristics - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive...

    On SCSI hard disk drives, the SCSI controller can directly control spin up and spin down of the drives. Some Parallel ATA (PATA) and Serial ATA (SATA) hard disk drives support power-up in standby (PUIS): each drive does not spin up until the controller or system BIOS issues a specific command to do so. This allows the system to be set up to ...

  7. Interleaving (disk storage) - Wikipedia

    en.wikipedia.org/wiki/Interleaving_(disk_storage)

    In block storage devices such as hard disk drives, interleaving is a technique used to improve slow system performance by putting data accessed sequentially into non-sequential blocks, typically sectors. The number of physical sectors between consecutive logical sectors is called the interleave skip factor or skip factor. [1] [2] [3]

  8. Shingled magnetic recording - Wikipedia

    en.wikipedia.org/wiki/Shingled_magnetic_recording

    Seagate started shipping device-managed SMR hard drives in September 2013, stating an increase in overall capacity of about 25% compared to non-shingled storage. [1] [11] In September 2014, HGST announced a 10 TB drive filled with helium that uses host-managed shingled magnetic recording, [12] although in December 2015 it followed this with a 10 TB helium-filled drive that uses conventional ...

  9. IOPS - Wikipedia

    en.wikipedia.org/wiki/IOPS

    Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN).
