The low cost M.2 PCI Express SSD are the most popular model while the cheaper 120GB has a higher per GB cost, the 240GB model had abundant room with 240GB for an operating system and some applications. The KingDian NV400 240GB SSD was only $55 plus taxes Canadian.
|Maximum Read||1381 MB/s||1628 MB/s||1465 MB/s||1565 MB/s|
|Maximum Write||387 MB/s||387 MB/s||1049 MB/s||1190 MB/s|
The orange models are PCIe while the blue models are SATA. At least KingDian makes it easier to select the right technology. The low cost KingDian uses PCIe 3.0 which is more than enough to handle the bandwidth of the commodity TLC NAND SSD chips used.
- M.2 2280
- ARM Cortex A5 controller
- NVMe 1.2
- PCIe 3.0
- TLC NAND
- 256MB cache
- MTBF 2 million hours
The ARM Cortex A5 is used for the controller. This is a lower cost design as compared to using a PCIe devices such as Silicon Image etc. KingDian has done well to reduce costs while maintaining excellent performance.
The average selling price for commodity SSD products is making the move to motherboard mounted operating systems the way forward. With lower prices adoption of SSD for the operation system is definitely accelerating.
The AM4 platform provides 4 lanes from the CPU to support the M.2 SSD which means the data is loaded into the CPU directly. Intel Sky Lake and above also support M.2 NVMe SSD. The full ATX X470 and X570 are known to have dual M.2 slots. Full ATX B550 motherboards also have dual M.2 slots. Many gamers use both slots as they get larger capacity SSD models; the second slot allows the old one to be used for more games installed.
To be sure this budget friendly SSD is not going to win any contests for performance but this product is aimed at the budget market which is much more mainstream. The 240GB is adequate space and the use of PCI Express means that it works with all of the AM4 motherboards in the studio. Intel users with SkyLake and above will also appreciate the affordability of KingDian.
AS SSD shows the KingDian NV460 NVMe SSD to be a good performer. KingDian uses a smaller 256MB cache to improve performance with PCIe 3.0 interface speeds.
