#The best nas for home users install
A computer that has M.2 NVMe or M.2 SATA3 slots, aiming to install SSD drives to speed up NAS performance through SSD cache acceleration is highly recommended. Therefore, this is the first thing you should check and then go buy a model according to your needs.

We must pay close attention to both the theoretical capacity of the hard drives and the type of RAID chosen, we must also take into account that we can reserve some space for the snapshot function, something that will reduce the effective space. To form a RAID 5 at least 3 hard drives are required. RAID 5: Assuming all drives are equal in capacity, the total capacity is the sum of all drives minus the capacity of one drive.RAID 1: Assuming all drives are equal in capacity, the total capacity is half the sum of two hard drives.RAID 0: Total capacity is the sum of all disks.We must take into account the types of RAID that exist and how they work, the most common RAIDs are the following: For a domestic environment, we believe that a computer with 2 or 3 drive bays is more than enough to have a very good storage capacity, especially if you install large capacity hard drives such as Seagate or WD of 10TB or more. Depending on the storage capacity that we want to have in our equipment, we will have to choose a 2-bay NAS, which is the recommended minimum, or go for equipment that has 6 bays and even more. This is the first question we must ask ourselves. Next, we are going to try to answer the main questions that we can ask ourselves when buying one of these devices.

When we are going to buy a NAS server, we have to look at many aspects, such as the processor, maximum RAM that it allows, the bays to house storage disks, if we have one or more Ethernet ports, which brand to choose and even if it is complicated to use it.
