Fixed drives USB, eSATA and removable drives RAID support [a] Shows S.M.A.R.T. attributes Hard drive self-testing Notification Notes AIDA64: Windows: Trialware [1] GUI IDE(PATA), SATA, NVMe eSATA, USB Some RAID controllers Yes No Monitoring only available in the Business Edition [2]
BeyondRAID is not a true RAID extension, but consolidates up to 12 SATA hard drives into one pool of storage. [27] It has the advantage of supporting multiple disk sizes at once, much like JBOD, while providing redundancy for all disks and allowing a hot-swap upgrade at any time. Internally it uses a mix of techniques similar to RAID 1 and 5.
Another example of software that shows the health of the drive and its smart attributes. This Intel 120GB SSD also appears to be in perfect condition. [2] Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T. or SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [3]
A disk compression software utility increases the amount of information that can be stored on a hard disk drive of given size. Unlike a file compression utility, which compresses only specified files—and which requires the user to designate the files to be compressed—an on-the-fly disk compression utility works automatically through resident software without the user needing to be aware of ...
MAID (massive array of idle drives) is an architecture using hundreds to thousands of hard drives for providing nearline storage of data. MAID is designed for write once, read occasionally (WORO) applications. [14] [15] [16] Compared to RAID technology, MAID has increased storage density, and decreased cost, electrical power, and cooling ...
Enterprise-class drives can have a height up to 15 mm. Seagate released a 7 mm drive aimed at entry level laptops and high end netbooks in December 2009. Western Digital released on April 23, 2013 a hard drive 5 mm in height specifically aimed at Ultrabooks. [37] Toshiba MK1216GSG 1.8" 120 GB hard disk drive with Micro SATA
The SuperDisk hardware was created by 3M's storage products group Imation in 1997. Serial ATA (SATA) Also Serial AT Attachment. A computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
