Enhance QNAP NAS with SSD for NAS "WD Red SN700 NVME SSD"!"What works for?" "Cash? Hierarchy?" "Over Provisioning?"

"Access speed" and "internal processing" are faster by setting the NAS into "HDD+SSD" configuration.

　Now that the SSD performance is increasing and the price has been reduced, the NAS is active in the adoption of SSD.

　Until now, all flashes, SSD cache, and hierarchical storage were mostly enterprise use, but recently, even small and medium -sized NAS for 4 bay classes and 2 bays for home use, use SSD.Is becoming possible.

　At present, there are two types of advantages to use SSDs in the NAS.One is to improve access via the network.By using SSDs that are faster than HDD for cache, etc., access when using storage in frequently used files and virtual environments can be speeded up.

　The other is the speed of internal processing.At present, the NAS is increasing not only as a storage of data, but also as a server that is responsible for various processing, such as virtualization and data analysis.

　Among them, it is easy to experience the effects of SSDs.I think many people use the NAS as a place to save photos, but the NAS has a function that not only saves images, but also automatically generates and classifies the thumbnails in the saved photos.There is.

　For such processing, when accessing storage internally, random access can be a bottleneck in HDD, which can lead to a decrease in the processing speed of the entire NAS, but using SSDs for cache etc. is fast.Processing can be realized.

　Now that the NAS is not only storing data, but also a platform for utilizing the data, speeding up with SSD is becoming the key to determining comfort.
