My colleague Aaron Lai, a couple of our friends, and I were chatting on the plane on the way to San Antonio back in February when I totally misheard something Aaron said. The four of us occupied an entire row on an Embraer E175, where Aaron sat on the far left, followed by our friend Chris, me, and another friend Jesse. We were talking about a situation one of my friends was in when Aaron asked me to pull up a photo of her, since he did not know who I was talking about. "She looks like someone who could be a Hong Kong grandma," I heard from across the aisle. A bit confused, I replied, "That is an interesting way to describe someone of her age, but okay." Aaron nodded, albeit in an also somewhat confused state. Chris, watching the whole situation unfold, turned to me and said, "Aaron said she looks like someone who could be in a Hong Kong drama, not someone who could be a Hong Kong grandma." We all burst out laughing at probably one of the weirdest miscommunications we had in recent times. (For Aaron's side of the story, please see the Cooler Master MH650 review.) Now, while confusing someone to be a Hong Kong grandma may be hard to forgive as a trivial mistake, I would not blame you if you glanced over the differences between the Western Digital Red WD140EFFX 14TB and Red Pro WD141KFGX 14TB. Both are 14TB drives from the NAS-oriented WD Red lineup, but they are actually quite different under the hood. The Pro variant we reviewed a few weeks ago is a 7,200 RPM HDD optimized for large servers, while the vanilla version we are looking at today is a slower unit designed for smaller systems with a lower price tag. But what do all these mean when it comes to the performance charts? Read on to find out!
Our review unit of the Western Digital Red WD140EFFX 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 WD140EFFX 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 Pro WD141KFGX 14TB, which we looked at a few weeks ago. 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.
