A good 4 bay NAS comes with a reasonable price tag. As a rule, you get most software support from the brand at an affordable price, where RAID 5 configurations are a priority. Besides, a 4-bay NAS is designed as a starting point for most of the latest hardware options. This trend demonstrates the rapid evolution of the 4-Bay NAS between brands. What's more, multiple updates that came in 2020 in the storage world have been applied to the specs of just a few 4-bay NAS. When compared to 2018-2019 technologies, it can result in successful bargains.

Many NAS devices have diskless drives. Thus, the network-attached storage device works without any storage device. Besides, some low-priced devices that come with little memory may not be upgradeable, so you have to buy additional hard drives. Keep this in mind while looking for the best 4 bay NAS.

Since NAS uses dedicated central processing units or computer processors, it has much in common with a personal computer. Though the processors of NAS and computers are similar, even the best 4 bay NAS has less power compared to a PC. Since NAS doesn’t require launching the OS or loading executable files, the workflow is satisfactory with lower speeds.

Another common function of NAS and PC is RAM. It demonstrates the speed with which the network-attached storage can access or call up files located on disk drives. In this case, the more RAM, the better. We especially recommend choosing a bigger RAM value for those who work with large files and need a lot of storage space for keeping them.
