"I could not start my computer," my supervisor said with a tone of worry in his voice. "Is there any way to retrieve my data?" "Did you back up your data?" I asked him. "No," he replied. Does that seem like a scenario you can relate to? From my colleague Ben's recent article on the Acronis True Image 2018 to my quest to build the 32TB network attached storage system a few months ago, everyone here at APH Networks -- and I would say, across the internet -- will tell you how important it is to back up your data. My theory is if I ever lost my data, I would pay at least a few hundred dollars to get them all back. But if those few hundred -- or even few thousand dollars -- is not enough to recover my terabytes of data should that ever happen, why not pay that money now and ensure I will never lose my data? Of course, there are many ways to keep your documents and memories safe. External hard drives are economical, while always-on network attached storage systems are faster, more convenient, and considerably more versatile in what it can do. As a fan of the latter, earlier this year, I took a look at Western Digital's Red WD80EFZX 8TB NAS hard drive. Although it delivered as promised in every meaningful metric, it was down a couple of terabytes in capacity compared to the excellent Seagate IronWolf ST10000VN0004 10TB. Well, fear not my friends: The Western Digital Red WD100EFAX 10TB brings the lineup back to the game in the capacity challenge. But will it still deliver in speed, power efficiency, and price?
