Since the dawn of computing, long-term mass storage has been a primary factor in the design of systems. At issue is speed, density of storage, and of course, fault recovery. In the beginning of the PC ...

A fundamental keystone of data protection, Raid (redundant array of independent disks) has been around for decades. The building blocks are very simple. Multiple disk drives allow data to be ...

This information is also available as a PDF download. Since I've been doing a lot of coverage of storage technology both for the enterprise and for the home lately, I thought I should give an ...

As a fundamental of data protection, Raid (redundant array of independent disks), has been around since the mid-1980s. The idea is quite simple; use multiple disk drives to enable data protection (via ...

Your computer's basic input/output system controls system-level hardware settings. For example, the BIOS has an "official" system clock. It also handles keeping track of physical hard drives, deciding ...

Striping and parity across three drives, oh my! Of all the RAID levels that consumers are likely to use on their home systems, RAID 5 is one of the more exotic choices. While RAID 0 and 1 are pretty ...

In simple layman’s terms, RAID is a technology that allows users to combine multiple physical disk drives into a single unit. This improves data storage performance and reliability, enhances data ...

I got into an argument with a colleague about RAID levels (specifically RAID5) and whether the redundancy was accomplished through parity or ECC. The standard sources all refer to the RAID5 array ...

In the late 1980s, processing power and memory performance were increasing by more than 40% each year. However, due to mechanical limitations, hard drive performance was not able to keep up. To ...
