RAID—redundant array of inexpensive disks—is one way of either getting more capacity or more data security out of your storage system. If you’re willing to commit enough disks, you can get both speed ...

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 ...

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 ...

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 ...

There are many levels of IT hell. Surely, one of the worst of those involves coping with the looming torture of RAID 5. RAID has been with us for more than 20 years, and during that time has saved the ...

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 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 ...

Tuning Raid performance has the air of a black art to storage administrators, with the perception that it can do more harm than good. Most consider the job done once the Raid level is selected. But, ...
