Dedicated Hosting Companies Offering Different RAID Levels

godaddy1There are a few dedicated hosting companies that offer different levels of RAID. But, before we jump into those companies (and what they offer), let’s go through what RAID is and why you may want it.

RAID Explained Simply

Multiple drives in a Redundant Array of Independent Disks (RAID) is one very good way to prevent a complete hard disk collapse. When a hard disk fails, the result is often catastrophic and can mean lots of lost revenue. To avoid this kind of disaster, RAID options are sought out.

In basic terms, a RAID storage system includes two (sometimes more) hard disks that are combined to form one single disk. This single disk is sometimes called a virtual disk. RAID storage makes for faster transfer rates, a much lower possibility of complete data loss, and a larger storage option (usually at a reasonable price). In short, you’ll want to go with a RAID setup.

Where can you find a dedicated hosting company that provides different levels of RAID?

Top Hosting Companies Offering RAID Levels

  • GoDaddy – RAID 0,1,10
  • RackSpace – RAID 0-10
  • Diadem Technologies – RAID 0-10
  • A Small Orange – RAID 10
  • BlueHost – RAID 10

What Are RAID Levels?

All of these companies offer various RAID levels. To break this down further, let’s take a look at what a RAID level actually is.

  • RAID 0: this level is also called ‘disk stripping,’ and it’s used mostly to heighten the performance of a server. There is no fault tolerance included with RAID 0.
  • RAID 1: also called ‘disk mirroring,’ this level of RAID copies (or mirrors) data from one disk to another. Benefit: if one disk dies, the other disk keeps ticking.
  • RAID 5: this is the RAID level that most sales reps will probably suggest for your small business. Why? RAID 5 means that data is included in 3 separate disks, so the failure rate is much lower with RAID 5. RAID 5 also ensures that segments of disks are not completely lots when various parts of a disk burn out. RAID 5 also works well with NAS devices.
  • RAID 1+0: this is also called ‘RAID 10.’ Basically, RAID 1+0 combines the best from RAID 1 and RAID 0. So, that’s both mirroring and striping. Servers that go through numerous write operations on a daily basis will benefit from RAID 10.

Additional RAID Options

There are a number of other RAID levels offered, though most of those levels are not sought after by small business owners. Most variants of the RAID levels listed above are really specific and are used in very specific cases. Hosts may suggest a different levels of RAID if you have really specific requirements.

You will find that most hosting companies offer the RAID levels outlined above, though some offer additional RAID levels. The best way to compare rates is to, as always, shop around for what you will need. If you aren’t sure about what RAID level to use, contact us – we’re happy to help.
