Design and Hardware
Both the contenders have the same rectangular-shaped design with curved edges. Both of them seem to have equivalent dimensions but Red Plus is relatively heavier than its competitor.
They both have a design that consists of the raid error recovery control which helps to reduce failures within the NAS system.
WD Red is designed with multi-Bay NAS drives which help in protecting your data.
It has very tighter regulation which prevents vibration to a great extent.
Their shape with flexible design makes them optimized for multi-drive use.
When talking about WD Red Plus design, it is made with 6 arms but only five platters with a total of 10 heads and also has a parking frame for the heads.
It also contains very powerful neodymium magnets. It consists of a desiccant bag within its structure to keep the moisture out of the hard drive.
The design and hardware specifications of both contenders are almost the same. But WD Red Plus will be considered superior to its competitor due to its slightly more advanced design as it is been built for usage in small and medium-sized companies whereas WD Red is used mostly for home purposes.
Parameter | WD Red | WD Red Plus |
Dimensions (L × W × H) | 147mm × 101.6mm × 26.1mm | 147mm × 101.6mm × 26.1mm |
Weight, g | 640 | 690 |
Form Factor | 3.5-inches | 3.5-inches |
Common Features of both drives:
- Both the contenders have a motherboard with the right interface, slots, and form factors making them very compatible.
- Both the contenders deal with vibration and noise quite well preventing read-write errors in the operation
- Both are made with exclusive NASware 3 Technology which improves the system storage performance by increasing integration, reliability, and upgradeability.
Features of WD Red:
- It comes with SMR recording technology which helps in writing data to a hard disk drive.
- It offers a performance class of up to 5400 rpm.
Features of WD Red Plus:
- It is made with dual balance control technology which enhances the performance over time by preventing excessive vibration and noise in the drive.
- It is designed with CMR recording technology which aligns the poles of a magnetic element perpendicular to the surface of the disk in a hard drive.

Cache Memory
Cache memory plays an important role in enhancing the performance of a hard drive.
Cache memory stores program instructions and data which are used repeatedly in the operations of the program and provides data required by the CPU.
A higher size cache memory always has an added benefit as it improves the efficiency of data retrieval.
Red has a 256MB size while WD Red Plus has a 128MB size. Red has two times more size than its competitor which makes it superior in this category.
Parameter | WD Red | WD Red Plus |
Cache Memory Size (2 TB) | 256MB | 128MB |
Which offers better Storage Capacity?
Both the contenders offer 4TB, 6TB, and 8TB storage capacities but Red Plus is available in more sizes than its competitor.
Due to higher product diversity, WD Red Plus will be considered superior to its competitor in terms of storage capacity.
Parameter | WD Red | WD Red Plus |
Storage Capacity | 2TB, 3TB, 4TB and 6TB | 1 – 4TB, 6TB, 8TB, 10TB, 12TB, 14TB |
Power Requirements
The more power required by the hard drive to fulfill specific operations, the more heat will be produced with a higher energy bill to be paid.
WD Red requires more power to work efficiently in both scenarios, when it is reading/writing or when the device is idle.
This makes it inferior to its competitor in this category.
Hence, WD Red Plus becomes more energy efficient with lower power requirements than its competitor.
Working Situation | WD Red | WD Red Plus |
Read/Write | 4.8W | 6.2W |
Idle | 3.1W | 4.1W |
Transfer Speed Differences
Red has a higher transfer speed in 4TB, 3TB, and 2TB hard drives than its competitor.
Although WD Red Plus has a higher transfer rate in 6TB drive, still it would be considered inferior to its competitor in this category due to WD Red providing higher transfer speed in more available sizes.
Devices Speeds | WD Red | WD Red Plus |
2TB | 180 MB/s | 175 MB/s |
4TB | 180 MB/s | 175 MB/s |
6TB | 180 MB/s | 185 MB/s |
Performance Differences in Extreme Temperatures
Every storage device has an operating temperature range which shows us how efficient the hard drive is in extreme temperatures.
Hard drives with a broader temperature range will always be considered superior in this category.
Both the contenders have the same temperature range of -40 to 70 oC in non-operating situations.
But the situation is quite different in operating conditions as the WD Red Plus takes the lead due to having a comparatively wider temperature range and wins this competition.
Operating Temperature Range | WD Red | WD Red Plus |
0 to 60 oC | 4TB and 6TB | – |
0 to 65 oC | 2TB and 3TB | 2TB, 3TB, 4TB, 6TB |
Is one more Reliable over the other?
Whenever we are discussing the reliability of a hard drive, its MTBF (Mean time Between failures) value will always be considered. MTBF is measured by dividing the total operational hours by the total number of failures that occurred in that period.
It simply gives us the value which will indicate for how long the hard drive will operate successfully before experiencing a failure.
Both the contenders have an MTBF value of 1 million hours which makes them equally reliable hard drives.
Reliability | WD Red | WD Red Plus |
MTBF | 1 million hours | 1 million hours |
