As always, with our storage reviews, before we move on to the benchmark results, let us briefly discuss the physical attributes of this hard disk drive first. The Red Pro WD141KFGX is your quintessential 3.5" hard drive from Western Digital; all you have at the top is bare metal with a dull silver finish and a large label placed across the middle. It weighs in at 1.52 lbs, making it lighter than the WD102KFBX 10TB at 1.65 lbs, but lighter than the WD121KFBX 12TB at 1.46 lbs. As a differentiating element between product lines, the top and bottom of the sticker is printed red in color, because, well, it is part of the Red Pro series designed for network attached storage systems. The label also says "WD Red Pro" at the bottom, just so you can tell this is not a regular Red. On the label, you will also spot information like its 14TB drive capacity, SATA 6Gb/s interface, WD141KFGX model code, NASware 3.0 firmware, manufacturing date on October 5, 2019 for our particular unit, and that it is a product of Thailand. The Western Digital Red Pro comes with a 5-year limited warranty compared to 3 years for regular model.
Turning the Western Digital Red Pro WD141KFGX 14TB around, and you will see a green printed circuit board that interfaces between its SATA 6Gb/s interface and the physical mechanical components. Mechanically, the Western Digital Red Pro WD141KFGX 14TB is a 7,200 RPM drive with eight high density platters inside. The drive is helium filled for reduced resistance, which means more platters can be stacked in the same amount of space along with reduced power consumption. With these high-density platters using conventional magnetic recording technology as opposed to performance-penalizing technologies like shingled magnetic recording, this should translate to great performance in our benchmarks. You will see 12.7TB in Windows. The rated power consumption is 6.2W under load, 3.0W idling, and 0.8W standby, which is excellent. It beats the Seagate IronWolf Pro ST14000NE0008 14TB and its 7.9W under load, 5.3W idle, and 0.8W standby rating.
As far as electronic components are concerned, the Western Digital Red Pro WD141KFGX 14TB features an Avago drive controller. The motor is controlled by a Renesas RAA300017 chip. A Samsung K4B4G1646E-BYMA DDR3-1866 512MB IC acts as the cache for the drive.
But before we delve into the benchmarking, I would like to spend a little bit of time discussing the unique characteristics of the Western Digital Red Pro WD141KFGX 14TB NAS drive. What makes a NAS drive a NAS drive? From a hardware perspective, usually, it will feature lower consumption. Since file servers are designed to be turned on 24/7, reduced power consumption can make a significant difference on your power bill, especially if you have many drives. Reliability enhancements are also made with what Western Digital calls 3D Active Balance Plus, which refers to the disk being physically balanced properly to reduce excessive vibration and noise in a multi-drive configuration, such as your network attached storage system. The WD Red Pro also features a multi-axis shock sensor, which was traditionally exclusive to enterprise class HDDs. What it does is it actively measures subtle shock events, and with dynamic fly height technology, it automatically compensates head positioning to ensure each I/O operation will not induce excessive physical wear on the disk components. Some network attached storage oriented models recommends no more than 5 drives per system, but the WD141KFGX will play nice even if you have up to 24 drives running concurrently. The Western Digital Red Pro WD141KFGX 14TB is also rated as having 1,000,000 hours MTBF.
As with all NAS drives, the Western Digital Red Pro is TLER enabled. If a drive is not TLER enabled, it may be dropped out of a RAID array unexpectedly down the road. TLER stands for Time Limited Error Recovery, which is Western Digital's name for a feature that limits a hard drive's error recovery time to seven seconds. Seagate calls this ERC. According to Western Digital, desktop hard drives may enter deep recovery mode and could take up to two minutes to deal with a bad sector. During this time, the hard drive will not respond. Because of this, RAID controllers may mark the drive as unreliable, because it has failed to respond within a set period of time.
For small NAS environments, most people probably will not need hardcore enterprise grade drives, which are usually quite expensive. Drives like the Western Digital Red Pro WD141KFGX 14TB are specifically tested for compatibility, designed for reliability, and comes TLER enabled from the factory to ensure you will not experience related issues down the road. With a price closer to desktop than enterprise drives, the Western Digital Red Pro series is simply a no-brainer if you are looking to fill up your file server.
