SAN technology and arrays
hard disk
A hard disk is part of a unit -- often called a disk drive, hard drive or hard disk drive -- that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces. Continue Reading
RAID 10 (RAID 1+0)
RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. Continue Reading
storage medium (storage media)
In computers, a storage medium is any technology -- including devices and materials -- used to place, keep and retrieve electronic data. Continue Reading

bad block
A bad block is an area of storage media that is no longer reliable for storing and retrieving data because it has been physically damaged or corrupted. Continue Reading
storage area network (SAN)
A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers. Continue Reading
AHCI (Advanced Host Controller Interface)
Advanced Host Controller Interface, or AHCI, is a technical standard for an interface that enables software to communicate with Serial ATA (SATA) devices.Continue Reading
Top five solid-state, cloud storage tips of 2017
In 2017, SearchStorage readers cared most about SSD lifespan, 3D XPoint technology and the difference between SAN and NAS. Check out our most-read articles of the year here.Continue Reading
block storage
Block storage is data storage typically used in storage-area network (SAN) environments where data is stored in volumes, also referred to as blocks.Continue Reading
SATA Express (SATAe)
SATA Express (SATAe or Serial ATA Express) is a bus interface to connect storage devices to a computer motherboard, supporting SATA and PCI Express protocols simultaneously.Continue Reading
Get ready for Gen 6 Fibre Channel technology
Some think Fibre Channel will go the way of the dodo thanks to Ethernet, but the evolution of flash will cause companies to make the leap to 32-gig FC eventually.Continue Reading

hybrid hard drive (HHD)
A hybrid hard drive (HHD), sometimes known as a solid-state hybrid drive (SSHD), is a mass storage device that combines a conventional hard disk drive and a NAND flash module.Continue Reading
RAID (redundant array of independent disks)
RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks to protect data in the case of a drive failure.Continue Reading
secondary storage
Secondary storage is used to protect inactive data written from a primary storage array to a nonvolatile tier of disk, flash or tape.Continue Reading
Secure Digital card (SD card)
SD cards use flash memory to provide nonvolatile storage. They are more rugged than traditional storage media and are used in more portable storage media.Continue Reading
flash memory card
Flash storage memory cards use nonvolatile semiconductor memory to store pictures, audio and video data on portable and remote devices.Continue Reading
