This is an example of productive and practical use of a RAID. Granted, this project does not have the archaic grandeur of a Floppy Disk RAID, but then again, the capacity and performance of this system are utterly superior to those of a Floppy Disk RAID

Storage performance has failed to keep up with that of other major components of computer systems. Hard disks have gotten larger, but their speed has not kept pace with the relative speed improvements in RAM and CPU technology.

RAID stand for a redundant array of inexpensive disks, a way of combining multiple disk drives into a single entity to improve performance and/or reliability. There are a variety of different types and implementations of RAID, each with its own advantages and disadvantages.

Most Linux users are familiar with the top command. Top shows you a list of processes on your system and provides a ton of useful information such as their CPU usage and owner. Unfortunately, this isn’t always enough data and many people don’t know where to turn next.

Having found the available information on system analysis rather sparse and/or written in such a fashion that is hardly of any use but to the people who wrote the actual documents,I have decided to write a series of articles on Linux system analysis.

GSmartControl is a really useful Linux app to check the health of your hard disk drive. GSmartControl is basically a graphical user interface for smartctl, which is a tool for querying and controlling SMART (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk drives. Only ATA drives including both PATA and SATA are supported for now.

If you read our "what's new in Ubuntu 9.10 Karmic Koala" post, you must know that a new hard disk tool is now available by default in Ubuntu 9.10: Palimpsest Disk Utility, which was created by Red Hat and is a S.M.A.R.T.

Turning from Metadata performance to throughput performance, we examines the impact of journal size on ext4 when the journal is disk-based. Dig into the numbers and see what you can do to improve throughput performance.

Just upgraded your system with a shiny new hard disk and want to make it your new book disk? Cloning Ubuntu to another hard disk is easy. In fact, Ubuntu provides tools to clone the entire hard disk -- including the Windows partition, if there's one on there. This is the kind of fundamental task that Linux excels at, in fact.
