For decades, PC users\u2019 computing efforts have been hindered by subpar hard drive configurations. In most cases, hard drives installed in a standard PC cause bottlenecking. And that results in a lot of lag and user frustration.<\/span><\/p>\n

RAID (<\/span>R\u00e9seau redondant de disques ind\u00e9pendants<\/b>) hard drives have the power (literally!) to change that. These hard drives, which can easily be added to most PCs and laptops, are unique in that they store data in multiple places. They do this by mirroring what\u2019s saved by the user onto multiple disks. <\/span>RAID databases<\/b> pair several hard drives together to increase performance and prevent data loss.<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t\t
\n\t\t\t

No solution is perfect!<\/span><\/h2>\n

Fun fact, RAID was originally an acronym for \u201cRedundant Array of Inexpensive Disks.\u201d So basically, we\u2019re talking about a relatively inexpensive way to reduce the chance of data loss <\/span>et<\/span><\/i> increase performance? Where do you sign up, right!?<\/span><\/p>\n

Not so fast. As with any other type of technology, <\/span>RAID arrays<\/b> can and do fail. Granted, storing the same data in many different places, as a <\/span>RAID database <\/b>does, is a great way to protect your information. But don\u2019t be fooled\u2014no hard drive is invincible.<\/span><\/p>\n

When your <\/span>RAID hard drive <\/b>fails, you don\u2019t want to be left out in the cold with a broken, useless piece of hardware and no data. Once you understand how a RAID hard drive works, there are a few steps you can take to prevent data loss in your RAID-based storage array.<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t
\n\t\t
\n\t\t\t

Configuration<\/span><\/h2>\n

There are many <\/span>RAID array types<\/b>, and not all are created equal. Each <\/span>RAID type <\/b>has its own set of redundancies to foster <\/span>data loss prevention<\/b>. Before you decide which is right for you, take a moment to determine what you need to accomplish and how a <\/span>RAID hard drive <\/b>can get you there. There are a few popular types of <\/span>RAID arrays<\/b>et<\/span> it\u2019s helpful to have a little background info on each.<\/span><\/p>\n

RAID 0<\/span><\/a><\/h3>\n

This <\/span>RAID drive<\/b> uses two or more disks to improve server performance. Known as \u201cdisk striping,\u201d this lets the PC use disks to smoothly perform several functions simultaneously. But in this configuration, when one disk fails, the whole array is affected. So RAID 0 is a poor choice for users with a great deal of data to store.<\/span><\/p>\n

RAID 1<\/span><\/a><\/h3>\n

RAID 1 uses \u201cdisk mirroring\u201d where two or more disks mirror one another to reduce data loss. In a RAID 1 hard drive, data is seamlessly copied from one disk to another, creating a mirror image of the information and a built-in copy of everything the user creates. Although this approach reduces data loss, there is always a bit of lag in computer function during the initial mirror build. After that, the speed will go back to normal in a hardware RAID and in most software RAIDs.<\/span><\/p>\n

RAID 5<\/span><\/a><\/h3>\n

This <\/span>RAID hard drive <\/b>employs both mirroring <\/span>et <\/span><\/i>stripping to increase performance and reduce data loss. RAID 5 is most often used in enterprise set-ups, but there can be a bit of lag in systems with many users who perform write operations.<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t
\n\t\t
\n\t\t\t

Back up your data<\/span><\/h2>\n

Backing up your data seems like a no-brainer, and it should be! But there are still people out there who don\u2019t.<\/span><\/p>\n

According to<\/span> Backblaze<\/span><\/a>, 76 percent of users do back up their information. That\u2019s not too shabby, but in reality most of those users only back up once a year. Think about everything you generate in a year\u2019s time. Do you really think protecting your data only once a year is OK?<\/span><\/p>\n

With easy access to <\/span>personal cloud storage,<\/b> there\u2019s really no excuse not to back up your data. There are even several applications available to automatically handle the task. This is a \u201cset it and forget it\u201d situation, meaning you don\u2019t even have to get involved! Or you can stick to the old-fashioned way, and use a good old external hard drive. It really doesn\u2019t matter how you back up your data, just do it!<\/span><\/p>\n

Of course, no matter how you choose to back up your information, understand a <\/span>RAID array<\/b> is <\/span>not<\/span><\/i> a backup plan. So get on a backup schedule, follow that schedule and protect your data!<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t
\n\t\t
\n\t\t\t

Prepare for failure<\/span><\/h2>\n

The question is not <\/span>if<\/span><\/i> your hard drive will fail, but when. In the case of <\/span>RAID hard drives<\/b>, they\u2019re usually comprised of hard drives created at the same time, with the same materials, by the same manufacturer. It stands to reason they\u2019ll all probably fail at or around the same time.<\/span><\/p>\n

Not even three or more hard drives can protect your information if they fail all at once. So keep your data safe by regularly monitoring the status of the <\/span>RAID drives<\/b>. Track your <\/span>RAID array <\/b>use, and create a plan of action to swiftly respond to any RAID failure. <\/span><\/p>\n

If you notice one <\/span>RAID array failure<\/b>, replace the drive immediately. Wait too long, and you may have two or three hard drives down by the time you get around to fixing it. When that happens, for the best chance of recovering your data, definitely call in a data recovery professional. <\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t
\n\t\t
\n\t\t\t

Too many failed disks<\/span><\/h2>\n

When you\u2019re confronted with a failing <\/span>RAID hard drive<\/b>, you may be tempted to perform a rebuild operation. This is a process where data is copied to a different drive while the failed drive is replaced. After the fix, the data is restored, and you can get back to work. <\/span><\/p>\n

You may have success with a rebuild if there\u2019s only one disk to replace. In such cases, <\/span>RAID hard drives <\/b>usually have a \u201chot plug\u201d where hard drives can be (somewhat) easily switched out. Once the bad drive is replaced, the user can run the rebuild operation and essentially start over without losing any data.<\/span><\/p>\n

But this solution isn\u2019t completely foolproof. There\u2019s always the chance of something going wrong during the rebuild that causes additional damage. Before you do something you can\u2019t undo, consider using a data recovery specialist to extract your information.<\/span><\/p>\n

When two or more disks fail on your <\/span>RAID hard drive<\/b>, your best bet to prevent data loss is to send the drive to a data recovery specialist. If you attempt to replace more than one <\/span>RAID drive <\/b>yourself<\/span> and run a rebuild, you risk losing your data forever. So don\u2019t!<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t
\n\t\t
\n\t\t\t

Take a picture, it lasts longer<\/span><\/h2>\n

If you do attempt to rebuild your <\/span>RAID hard drive<\/b>, create an image of the hard disks\u2019 content <\/span>before<\/span><\/i> you begin to rebuild.<\/span><\/p>\n

Again, rebuilds aren\u2019t a guarantee, especially when you take on the task by yourself. But with an image of the content, you stand a chance of recovering the data should the rebuild fail. In that situation, a RAID data recovery specialist<\/a> can use your images to recreate the <\/a><\/span>RAID drive. <\/b>Just be sure to label the content. <\/span><\/p>\n

While there are many advantages to using a <\/span>RAID hard drive<\/b>, no piece of hardware is ever perfect. Like all technology, they\u2019re fallible, complex and will, at some point, fail. <\/span><\/p>\n
