Being in the data recovery business, many of our clients often ask us “What hard drive should I buy?” That is not an easy question to answer without some additional research and data. In a previous post entitled “Looking To Replace Your Hard Drive” I discuss six key factors to consider 
when replacing your hard drive. They are:

  1. Drive Type
  2. Storage
  3. Cache Space
  4. Transfer Speeds
  5. Access Times
  6. Price

Sounds fairly straight forward and simple until you understand that hard drive manufacturers have different models just like an automobile dealer. Let’s look at 2 of the top hard drive manufactures and their hard drive systems.

Western Digital for instance offers a large variety of hard drive systems based upon your computer type and needs. They are broken out by color for easy selection. For example:

PC & Mac

WD Blue


WD Black

NAS Hard Drives

WD Blue


WD Black

Surveillance Hard Drives

WD Purple

WD Purple NV

WD Gold

Seagate Hard Drives segments it’s hard drive systems by animal names. For example:

Barracuda – PC & Gaming  – HDD

Firecuda – PC & Gaming SSHD

Ironwolf – Netork Attached Storage (NAS)

Skyhawk – Surveillance

Are you confused yet?  I know I am!  There is no simple answer. The hard drive you select depends upon your needs and how much you are willing to spend. In an effort to make your research a little easier, I have included a link to Backblaze a hard drive data center  which has 50,228 drives spinning in their datacenter. This site will provide you with a lot of the technical data and information you may need to select a hard drive.

In conclusion, selecting the right replacement hard drive is complicated. The 6 factors I recommend above are key to finding the right hard drive for your needs. Use Backblaze to finalize your research and decision making process. If you have any questions, please feel free to give Carolina Data Recovery a call. We are your Hard Drive Data Recovery Experts.
