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 ...

What is RAID, why do you need it, and what are all those mode numbers that are constantly bandied about? RAID stands for “Redundant Array of Independent Disks” or “Redundant Array of Inexpensive Disks ...

Ever since its invention in the late 1980s, Raid (redundant array of inexpensive disks) has been a mainstay of data protection on shared storage arrays and in enterprise servers. But, as the capacity ...

The history of RAID can be regarded as the history of redundancy due to data distribution. In the figure, green represents the parity that protects the data, and yellow represents the hot spare that ...

Am I missing something here... ? It was my understanding that with a RAID setup, it was possible to increase performance (not taking into account reliability) above that of a single disk. Let's say I ...

RAID allows two or more disk drives to be seen by the operating system as one physical drive. This allows for fault tolerance on your computer so that if one drive fails, the data is securely still ...

In the first post on this subject I discussed btrfs basics, showing how to create simple btrfs filesystems. In the second post, more on btrfs, I showed how btrfs filesystems can be dynamically resized ...

The USB standard allows many peripherals to be connected using a single, standardized interface. Proven over the years as a reliable, expandable, fast, low-cost, low-power, and hot-pluggable interface ...
