A Brief Overview of NAS and RAID Systems

NAS systems are defined as Network Attached Storage devices and are increasingly popular arrangements that provide a central storage point—almost like a private cloud—where small businesses can backup critical files and data. Comprised of an external storage device that connects to a network, NAS facilitates data storage and retrieval from a centralized location. Data storage and protection is critical for companies to maintain effective operations. Absent the ability to retrieve important data, lost sales, team miscommunication, reduced efficiency, and poor customer service can ensue—all potentially leading to income loss.

Benefits of NAS

NAS systems provide numerous advantages:

  • Easy to use, even for the non-tech-savvy person
  • Promote peace of mind through regular backup and data storage
  • Facilitate remote access
  • Impressive value and cost-effectiveness
  • Reliable and accessible in case of power or internal drive failure
  • Are flexible and scale-out to grow along with companies’ storage needs
  • Reduce out-of-sync, non-centralized data 
  • Offer RAID technology in case of hard drive failure when hosting more than one internal drive

What is RAID?

Western Digital posted an excellent description of how a RAID works (in layman's terms)

RAID stands for Redundant Array of Independent Disks and works to combine multiple drives’ storage capacities into a single volume. To successfully use RAID, a business must have at least two internal drives. RAID offers faster speeds and/or greater storage capacity. While somewhat complicated, RAID-capable devices come preconfigured to reduce time and headaches.

RAID is available in various configurations:

  • RAID 1—also known as “mirroring”—in which data is written identically and simultaneously to both drives. This protects functioning if one drive fails. Primary disadvantages are that regardless of the number of drives, the capacity is only for one, and it has slower writing speeds.
  • RAID 0—combines each drive’s capacity into a single volume to maximize volume and bandwidth. However, if one drive fails, then all information is lost if another backup is not used.
  • RAID 10—an amalgamation of RAID 1 and RAID 0 used primarily with four internal drives to improve data safety and performance.
  • RAID 5—requires three internal drives and distributes data throughout all drives while ensuring data safety if one should fail. This is the most preferred configuration.
  • RAID 6—similar to RAID 5 but can protect data if two internal drives fail simultaneously. It is used primarily for devices with at least five internal drives.

NAS versus RAID

RAID-enabled systems utilize two or more hard drives to improve performance and fault tolerance. Fault tolerance is a safety net of sorts in case of a failed internal drive. For organizations that require high fault tolerance and optimized performance, RAID is the way to go. 

It is crucial to remember that RAID is neither a backup nor should it replace a backup strategy. Whereas backing up data to a RAID device would be part of such a strategy, using a RAID device as a primary server or storage option is not. RAID is a great option for optimizing NAS performance and to quickly rebound in case of hardware failure, but should not be considered a panacea for a data catastrophe.

Client Reviews

“We had a hard drive failure at work, and we didn't have a backup. We went to Ron for a free analysis and he verified there was an issue within 15 minutes. We've never had to deal with data recovery before, and he was willing to answer any questions. He got our data restored to a new drive within 2 days. Would definitely recommend.”
– Seth Allen
“Great company with fantastic service! My laptop was causing me terrible issues and I was terrified that all of the valuable data that was stored on it was gone forever. I went to several different companies for help with no solution to my problem. I finally found Carolina Data Recovery and they were able to recovery all of my data that I thought I had lost forever. Friendly staff and great recovery time. I highly recommend this company! ”
– C. Haynes
“I researched a few places near me that are in the business of data recovery. When I called, I spoke with Mr. *** D****. He was optimistic that he could recover the data from our dead hard drive from our file server. He did not guarantee anything without an evaluation. I drove two hours and delivered the hard drive to him the next day personally. He checked the drive immediately while I waited. He was confident that his team could recover the data from the drive within 3 to 5 days. Surprisingly, Mr. D**** called me the next morning with the good news that his team had come in for an emergency job and completed the recovery on my hard drive during the night. They were able to recover 100% of the data. Mr. D**** was pleasant to work with. I hope I never need there services again, but If I do I would definitely work with them again. I would highly recommend.”
