1. ATTO Disk Benchmark test
ATTO Disk Benchmark is an excellent and free disk benchmarking software that supports read and write tests for stability/bursty transfer rates. It is suitable for the read and write performance of conventional hard disks, RAID, USB flash drives, removable memory cards and other products. test. In addition to testing the maximum read and write speed of the hard disk, you can also perform a 1-10 level queue depth read and write test to verify whether the speed of the hard disk is attenuated under the capacity load.
WD40EFRX-ATTO test
In the ATTO DiskBench test of WD40EFRX, the maximum read speed reached159.15MB/sec; Its maximum write speed reaches148.76MB/sec. Because of the low power consumption, the speed is only 5400RPM. Compared with the 7200RPM Western Digital Se series 4T hard disks, which are also targeted for small and medium NAS users, the performance is somewhat weaker, and the write speed and read speed are both about 20MB/sec behind. (Note: The speed measured by this software is generally slightly larger than the speed measured by other software. Many manufacturers use this software to obtain official data)
Two, CrystalDiskMark 3.01 X64 test
CrystalDiskMark is a simple and easy-to-use hard disk performance test software, but the test items are very comprehensive, covering continuous read and write, 512K and 4KB data packet random read and write performance, and queue depth（Queue Depth）4K random performance in the case of 32. The queue depth describes the maximum IO value that the hard disk can activate at the same time. The larger the queue depth, the higher the actual performance.
WD40EFRX-1000M（Data block size）
From the CrystalDiskMark test, the read speed of the WD40EFRX hard disk reached 152.7MB/sec, and the write speed also reached 147.7MB/sec. In terms of 4K random read and write, the performance is not bad.
Three, HD Tune Professional Edition v5.00 test
HD Tune is a hard disk performance diagnostic test tool. It can detect the transfer rate of the hard disk, burst data transfer rate, data access time, CPU usage, health status, temperature and scan the surface of the disk, etc. In addition, the firmware version, serial number, capacity, cache size, and current transfer mode of the hard disk can be detected in detail.

After HD Tune''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s “benchmark”and“file benchmark”test, we found that the read and write speed of WD40EFRX is not particularly ideal, the average read and write speed is only about 111MB/sec, butOutstanding burst transmission speed, reaching 293MB/sec, It is really surprising.
Through the test curves of different data blocks, it can be found that when the data block reaches 3.5TB or more, the read test curve of WD40EFRX is quite fluctuating, which may affect the transmission speed. Of course, the individual differences of the hard disk we got are not ruled out. Sex. However, it is impossible for a general data block to reach this size, so you can use it with confidence.
Four, CrystalDiskInfo 6 test
CrystalDiskInfo hard disk detection tool understands the health status of hard disks by reading S.M.A.R.T. Through it, you can quickly read the detailed information of the hard disk, including interface, rotation speed, temperature, use time, etc. CrystalDiskInfo will also make an assessment based on the S.M.A.R.T score, and will also issue an alert when the hard drive is about to be damaged.
WD40EFRX-Crystal Test
After all, it is a low-power product with a speed of only 5400RPM. After running and testing for 2 hours,It can be kept at 38℃, During the testThe mute effect is also ideal. It can be said that NAS network storage is very suitable for homes and small businesses.
5. Specially suitable for entry-level NAS users
From the picture above, we can clearly see the positioning of Western Digital Red Disk: an entry-level NAS product, suitable for individual users and small businesses with 1-5 disk positions. butEntry level does not mean low quality, The performance of the Western Digital Red Disk is quite good.
In terms of product category and positioning, Western Digital Red Disk is different from black disk, blue disk, and green disk., Because the latter three have obvious performance differences, and the red disk is on the same level as the green disk in performance（Of course positioning and unique features are different）; In addition, the latter three are all geared toward the retail market. In NAS products, colors are generally faded, and XE, RE, and SE are used to distinguish product levels. The red disk is a product specifically for NAS, of course, home users can also use it.
In this review, the WD40EFRXThe performance is quite consistent with its positioning, The red disk positioning is an entry-level NAS product with 1-5 bays, a low-power product, and the speed is limited to 5400RPM, so the performance is also greatly restricted. The maximum read and write speed is 156MB/sec, and the average read and write speed is 111MB/sec. Surprisingly, the maximum burst speed can reach 293MB/sec. In addition, after a two-hour high-intensity test, the temperature is still maintained at 38°C, and the mute effect is also very satisfactory.
The killer of the red disk lies in itsUnique NASware technology, It is specially designed for Raid''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s intelligent error recovery technology ——Through the built-in intelligent error recovery control mechanism, NASware can prevent the hard disk from being disconnected from the Raid because the error recovery time is too long, which improves the usability and shortens This reduces downtime and avoids rebuilding Raid. In addition, NASware will shut down after the execution of the running command in the event of a sudden power failure, which minimizes data damage or loss and simplifies the integration process.
From the above summary, everyone should be clear that the red disk inherits the IntelliPower intelligent adjustment technology of the green disk, has the characteristics of low power consumption, and has excellent heat dissipation and mute effects; at the same time, it also has NASware technology specifically for NAS services, which is more suitable for home and small Enterprise NAS users, if necessary, you can consider starting.
