What hard drive should I buy?

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.

Client Reviews

“Great service! Great company! After bringing my computer to three other companies - all who said my data was lost and gone forever - Carolina Data Recovery found and restored it as easy as 1 - 2 - 3. After all the ups and downs and horrors of computer problems, I'm so glad I found a place to go!”
– Anne Fiala
“I thought I had lost the last 15 years of my life in pictures, but they were able to recover them! Such a relief! Worth every penny!”
– Shannon M.
“The short: Calling Ron and his team was the best decision I could have made. Words like kind, respectful, prompt, and attentive come to mind. The long: My NAS crashed. I thought I lost my entire digital life. Forget about the files and documents one accumulates and all the music, I had 30 years of family pictures, some of who are no longer with us. I was in tears. I took my NAS to a big box store where I was given very robotic service by their "geeks" and was told it could cost me thousands of dollars, it would take at least a month (but I could leap to the front of the line for an extra $100) to even find out IF it was recoverable. I decided to look for someone local and thank God I found Carolina Data Recovery. Ron was able to confirm that the data was recoverable within 48 hours and had my data back to me within 72 hours. Beyond that, Ron took time to walk me though the process and listen to my concerns. Realizing I was a mess, Ron spent an hour on the phone with me explaining what I need to do going forward to ensure that this never happens again. Backing up your data IS important - hard lesson learned. I hope to never be in this situation again, but have comfort in knowing that Carolina Data Recovery has my back. ”
