Western Digital Red Pro WD141KFGX 14TB Review

If you have been following APH Networks for a while, you may have heard a few stories from my colleague Aaron Lai about our visit to the great state of Texas a little over a month ago. I have never been to Texas before, and since one of our friends moved there, Aaron and I along with two other friends decided to pay him a visit in San Antonio. There are many things I can talk about in our visit to the Lone Star State, but being someone who loves food and all, how can I not talk about that first? Texas barbecue was definitely the highlight of my trip. Along with whatever I ordered at the local steakhouses, Buc-ee's, or Tex-Mex restaurants, I ended up eating an absolutely unholy amount of meat. For the first few days, I am pretty sure the only vegetable I had was the slice of lettuce in my Chick-Fil-A Deluxe Sandwich. This was certainly not good for me and the input from my mouth was far from proportional to my output in the washroom. Back at home a week later, I had some oatmeal for breakfast. It was not long until I hit the washroom and I very much unloaded into the toilet. I just installed a new high performance toilet from Kohler, but my load was a way too much for it to handle and it got stuck. Maybe in a lot of ways, this is also how we create an absolutely unholy amount of data. The quality of the data we create may be questionable, but we still need to find a way to store them all. In recent times, Western Digital finally released their 14TB hard drive models, the Red Pro WD141KFGX I am reviewing today and the Red WD140EFFX I will be looking at shortly. This is quite a jump in capacity compared to the Red WD100EFAX 10TB I reviewed in 2017, but will it perform better too? Read on to find out!

Our review unit of the Western Digital Red Pro WD141KFGX 14TB hard drive came in medium sized, UPS branded corrugated cardboard box from the company's HGST subsidiary offices in San Jose, California. Using UPS Saver, everything arrived in excellent condition for our review today.

Inside the medium-sized brown corrugated cardboard box were two hard drives securely placed in the presence of lots of bubble wrap for maximum safety during transport. The Western Digital Red Pro WD141KFGX 14TB we are reviewing today was placed inside a sealed anti-static bag for additional protection. Also along the trip was the Western Digital Red WD140EFFX 14TB, which we will take a look at very soon. To be honest, I have never purchased a hard drive that is not in OEM packaging in the past, so this should be nothing new to most people.
