Design & Hardware

Both NAS hard drives are having a rectangular shape.

Red, as its name shows, has a red color with three vertical lines, silver lustrous corners, a white bottom portion with Western Digital written on it, and black background with the WD logo on its front.

On the other hand, Ironwolf’s front side has three portions.

The upper portion is green with the logo of Seagate, the bottom portion is Red with capacity mentioned on the right side, and the middle portion is shiny black with an Ironwolf logo.

Both of them are having almost the same dimensions but Ironwolf is relatively lighter which makes it more condensed and superior to its competitor.

Working Environment

The lifecycle span of the NAS hard drive is greatly influenced by the environment temperature.

An increased risk of failure can be due to the result of the higher temperature.

Both competitors seem to have a lower initial operating temperature of 0°C.

On the contrary, WD Red has a comparatively lower maximum operating temperature.

Hence, WD Red takes the lead for having a controlled and lower operating temperature comparatively.

The non-operating temperature of both the contenders is identical.

Both competitors are suitable for personal and small businesses but Ironwolf wins the race as it delivers exceptional performance in professional businesses.

A medium used to establish a connection between two unconnected units or entities is referred to as the interface.

Both contestants support the SATA 6 Gb/s interface, the third generation of SATA.

It is the major interface that links host bus connectors to hard disk drives, and optical drives that are termed mass storage devices. SATA is short for “Serial ATA” or “Serial Advanced Technology Attachment.”

The “6Gb/s” make sure concurrent data transfer speeds of 6 gigabits per second, and prolonged performance in high-bandwidth applications that are used to measure the amount of data downloadable from the server such as streaming high-graphics video.

Hence in this contest, both contenders ended up in a stalemate.

Rotational Speed

Rotational Speed measures the speediness of the travel of platters inside the hard drive. The quicker the movement of platters, the data bits move past the read/write head quicker, delivering higher data rates.

Ironwolf has an outstanding rpm of 7200 which means it has a good data transfer rate comparatively.

Power Consumption Idle Average (W)4TB = 3.14TB = 3.95

Data Transfer Speed

Ironwolf has two models in 4TB capacity.

One model has the same speed as WD Red.

But another has a comparatively higher data transfer speed.

So we can conclude that Ironwolf allows the quicker transmission of data from one place to another.
