ssd 512gb A good horse needs a good saddle: WD Red SSD+HDD combination makes NAS devices more powerful

solid state drive SSD OEM SSD 512GB as a studio engaged in video renderingSSD 512GB, the video material recorded can be described as quite large> SSD 512GB, and the massive amount of data makes the studio feel slightly overwhelmed, because these video materials are sometimes too much storage space, and each computer stores one, and feels that space will be wasted, so through a complete set of NAS combinations to let the entire company use the materials, which can not only improve work efficiency, but also reduce the hard disk space consumption of work computers, which is still very convenient for small businesses.

however, in previous NAS applications, it was mostly pure

two storage system combinations based on SSD solutions and pure HDD solutions, of which the combination of pure HDDs can obtain huge capacity, and the cost of building NAS is relatively low, but there is a fatal shortcoming, that is, the speed is not ideal, if you want to edit online video on HDD, the speed will seriously restrict the work process. The pure SSD combination can achieve ideal results, and 4K performance is also quite good, but the problem of pure SSD is that the capacity is severely limited, and compared to HDD solutions to build much more expensive, so the current SSD price has not reached a very low level, SSD as a cache, HDD acceleration is naturally the best choice Therefore, some video studios have begun to try the combination of SSD and HDD to build NAS systems, and some high-end NAS of Synology have gradually supported support for SSD+HDD combinations.

As a product specially built for high-load systems such as NAS, WD Red series storage products are obviously the best partner for NAS systems, so what is the difference between using WD Red storage combination for NAS and pure SSD? Will there be a big gap in performance? We chose a combination of WD Red SA500 NAS SSD+WD Red NAS HDD and Synology DS 1618+ NAS to build a complete NAS system.

For NAS equipment, the vast majority of consumers use multi-hard disk arrays, the need is 7×24 hours of continuous operation, to ensure that consumers can access the data anytime, anywhere, so the stability requirements for hard disks, especially SSDs, are very demanding, and ordinary hard disks will have certain data errors when running for a long time, and multi-hard disk arrays will continue to accumulate this error, resulting in hard disk ejection due to errors, and even damage to data. This is undoubtedly a major blow to video workers who use NAS for storage, so many hard disk manufacturers have launched a special NAS series of hard disks for NAS systems to ensure data stability.

WD Red SA500 NAS SSD is specially customized and optimized for the characteristics of high-intensity work of NAS, WD Red SA500 NAS SSD running low heat, low noise, especially suitable for 24*7 use environment, providing the best compatibility, as a NAS system cache disk, WD Red SA500 NAS SSD read speed 560MB/s, The write speed is 530MB/s, random 4K read 95K IOPS, random 4K write 85K IOPS, the performance is enough for NAS cache, in addition, Western Digital has also carried out strict stability tests on WD Red SA500 NAS SSD, and the 5-year limited warranty provided is a reassurance that Western Digital gives NAS users. Western Digital WD Red NAS HDDs use the latest NASware 3.0 technology to improve the compatibility, integration, upgradeability and reliability of hard drives, optimize the performance of any NAS system, and ensure data stability.

 In the CrystalDiskMark test software, the peak read and write performance of the hard disk can reach more than 561MB/s, which performs well in similar products. At the same time, the read speed can also reach 526MB/s, which is the top level in SATA SSDs.

using ATTO Disk Benchmark, the impact of different sizes of files on hard disk read and write performance was measured, and the actual results were very good.

file read test

WD Red SA500 NAS SSD can also achieve a score of 485MB/s in file reading, which is not much different from the theoretical performance. This time the core of the NAS system is the Synology DS 1618+. And the top and side sides are also integrated. The Synology DS 1618+ features a six-bay design that provides storage for up to six drives, with a USB 3.0 port at the bottom to connect external storage products. The upper part of the Synology DS 1618+ is designed with LAN1-LAN4 status indicators, which can extend up to four network devices outwards and check whether the network is operating normally by flashing lights.

Synology 1618+ is equipped with four Gigabit network cards, which can be used alone or aggregated up to 4000Mbps, but this time we re-equipped Synology’s E10G18-T2 10 Gigabit network card to provide write speeds of more than 1GB/s and improve file transfer performance.

This time used as NAS storage devices are WD Red SA500 NAS SSD from Western Digital and NAS HDD from WD Red. Among them, WD Red SA500 NAS SSD adopts SATA interface, which is specially optimized for the stability required by NAS 7X24 hours, which can meet the needs of enterprise office and private cloud construction. At the same time, the high-speed read and write characteristics of SSD can also be used as the cache of the entire system to improve the performance of the NAS system.

NAS interface

The operation of the Synology DS1618+ is relatively simple, this time we used four WD Red NAS HDDs to form Raid 5, while the WD Red SA500 NAS SSD was formed into Raid 1. On the NAS interface, you can also visually see the status of each hard disk.

In orer to improve the overall performance of the entire NAS, we also use the SSD that makes up Raid 1 as the cache of the NAS mechanical hard disk, which can greatly increase the overall performance of the NAS system, especially the performance of 4K random read and write. Of course, SSD as a cache obviously has a certain price, that is, reduce the storage space of the SSD, and if it exceeds the space of the SSD cache, then the actual performance will be reduced to the speed of ordinary mechanical hard disks. However, our set of SSD can provide up to 500GB of cache, which can naturally meet the video transmission needs in most cases, and can directly allow users to complete all daily editing in the cache, which greatly increases work efficiency.

NAS measurement: running full 10 Gigabit network card

As a video studio with very demanding performance requirements, the performance of the NAS system is naturally the object of attention for the studio. If the performance of the SSD+HDD combination is far from the SSD, then the cost performance of the build is not so high. We selected several well-known hard drive test software to test this storage combination, and chose pure SSD and pure HDD as a comparison to see how much performance difference between them?

WD Red SA500 NAS SSD+WD Red NAS HDD Mixed Mode

Through the test of CrystalDiskMark, it can be seen that after using WD Red SA500 NAS SSD as cache, the performance of the entire NAS system is very good, with a read speed of 1184MB/s, even more than double that of traditional SSDs.

WD Red SA500 NAS SSD+WD Red NAS HDD mixed mode

In ATTO’s test, based on 64MB of continuous read and write, WD Red SA500 NAS SSD+NAS mechanical hard disk combination can also achieve a read speed of nearly 1GB/s.

actual file copy

Of course, whether it is ATTO Disk Benchmark or CrystalDiskMark, they are both theoretical performance tests, actual file copying and reading or operation in Windows. In this regard, we also use 10 Gigabit network card simulation studio and NAS interconnection. As a result, in the actual file upload and download, the WD Red SA500 SSD+NAS mechanical hard disk combination also achieved more than 1GB/s performance, basically filling the upper limit of the 10 Gigabit network card.


 Through actual tests, WD Red SA500 NAS SSD+WD Red NAS mechanical hard disk combination can obtain better performance than mechanical hard disk, in addition, if the 10 Gigabit network card is used for transmission between computers, then even the largest video rendering file can be easily transferred in a short time, which is of great help to improve the work efficiency of employees. And through the two SSDs that make up Raid 1 as the cache of the entire NAS system, the performance of the hard disk with a total capacity of more than a dozen terabytes is raised to a notch as a whole, and it is obviously quite worthwhile to have a speed close to the native SSD.

Synology DS 1618+ with NAS-specific WD Red series products, you can easily build a high-performance data center, even 10 Gigabit network speed can easily cope with it, bringing great convenience to video studios, and the construction cost is much smaller than building pure SSDs. For those small and medium-sized video studios that value cost very much, this NAS combination is obviously a good saddle for the horse. solid state driveSSD OEMssd 512gb
