Can RAID Systems Fail?

RAID systems are incredibly robust, and can run mission critical business applications for years at a time. They are a major choice of most businesses who need to ensure that a single hard drive failure won’t damage their business at any level. But despite their robustness, the RAID system does have a single weak link: the mechanical nature of hard disk drives.

Hard Drive Failure – A Fact of Life?

Over the past 20 years, the Hard Drive as a technology has increased by leaps and bounds. In fact, at Hard Drive Recovery Group used to make our business recovering drives smaller than 10MB. Times have changed remarkably, of course, with Terabyte hard disk drives now common, and the ability for people to buy Petabyte drives(or 1000 Terabyte) not as broad a fantasy as it used to be (*although based on today’s HDD technology, a Petabyte drive is still unmanufacturable). The key point of drives today that make them more likely to fail than ever is their size, which contributes to the heat they generate, and thus their ability to fail.

Outside of newer Solid State Hard Drives (which are still too small and expensive to be used in most RAID systems), regular hard drives are simply mechanical beasts, somewhat similar to your car, at its heart, is still mechanical. And what we’ve seen is that mechanical objects are not just liable to fail, but are in fact doomed to fail. Age, heat and use take their toll on any system, and a RAID hard drive, with its higher level of use (corporate environments frequently show no mercy to a RAID hard disk), is not immune to failure at all. In fact, it is simply a matter of time.

Multiple Drive Failures – Where HDRG Comes In

With many failed RAIDs, the issue is rarely just a single hard drive failure. In fact, in the event of a single RAID hard drive failure, the RAID controller itself can frequently repair the overall RAID array with relative technical experience. In cases like this, your RAID support vendor can usually provide you with a solution that can be handled quickly and easily.

Where professional RAID repair shops like Hard Drive Recovery Group come in is with multiple drive failures. In most cases, if multiple drives have failed, or the RAID controller itself has failed, there is little you can do but call a professional. Once you have encountered this issue, it is in fact necessary for you to call a professional as soon as possible in order to avoid data loss. A simple fact most IT people do not know is this: the largest cause of data loss after multiple drive failure is one thing and one thing only: human error.
