The advantage for the true neophyte is that lmgtfy literally tells them how to use google and they see the process and are prodded to explore the results.
I see, its a tool to take the piss out of people who cant be bothered to use Google to search fore something that they might find on Wiki for example.
However this still does not seem to answer many "simple" questions that simply googling for does not often give you if what you want is not a very long Wiki article, but very basic abreviated explanation.
e.g. Wiki Says.
"RAID, an acronym for Redundant Array of Independent Disks (Changed from its original term Redundant Array of Inexpensive Disks), is a technology that provides increased storage functions and reliability through redundancy. This is achieved by combining multiple disk drive components into a logical unit, where data is distributed across the drives in one of several ways called "RAID levels". This concept was first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987 as Redundant Arrays of Inexpensive Disks. Marketers representing industry RAID manufacturers later attempted to reinvent the term to describe a redundant array of independent disks as a means of dissociating a low-cost expectation from RAID technology.
RAID is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple physical disk drives. The physical disks are said to be in a RAID array, which is addressed by the operating system as one single disk. The different schemes or architectures are named by the word RAID followed by a number (e.g., RAID 0, RAID 1). Each scheme provides a different balance between two key goals: increase data reliability and increase input/output performance."
I would say.
"RAID is a way of improving drive performance, capacity and reliability. You need at least 2 identical HDD/SSD's to do this at the most basic level and /4 at higher levels. There are drawbacks and it can be complicated to do and if it is not fully understood do not attempt this as it can be risky."
Most people I can understand would read the first paragraph of what is on Wiki and quite rightly say that it does not answer anything. The second paragraph may be perfect in its defenition but again does not give a suitable answer for many people. My very simple answer is just that, the vast majority of people will ask what it is in the most basic sence and then be put off by what it actually entails - if someone is still interested then they will be interested enough to actually read through the complexeties and dull meaningless crap in that Wiki article.
What a website like Wiki could really do with is a very basic bit of text to answer the basic question of "what is RAID" - that I assume is why so many people ask that very question, because they have already seen the Wiki article and have been put off of reading through it by its sheer length. Either way, telling someone how to Google something although amusing might really not be what the end user wants to see.
