Your questions is very generic & general, have you ever googled up these terms ?

NAS = Network Attached Storage
- Basically a device that connects directly to the network switch for connection & have like 1-2 bays or more of HDDs.
- It have the capability to use RAID technology ensuring data consistency & redundancy in case of any HDD failure (usually not more than 1 drive at any time).
- Most common NAS are Synology, QNap, WesternDigital, Seagate, Buffalo etc. Highly recommended is Synology because they have built-in OS & many plugins available to download & use.

RAID = Redundant Array Inexpensive Disk
- Is a technology that split/combine & cache all the installed HDDs.
- RAID0 = Stripping (eg. 100GB + 100GB = 200GB), not redundant but does increase Read/Write performance (IOPS). Seldom people use this level.
- RAID1 = Mirroring (eg. 100GB + 100GB = 100GB), redundant without parity, no performance increase, single drive failure only.
- RAID5 = Mirroring + Parity (eg. 100GB + 100GB + 100GB = 200GB), a min of 3 HDDs is required, single drive failure, but with Parity means less risk of data corrupt during HDD failure & data can be rebuild back via the Parity data. Usually used in enterprise server farms or data center.
- There are others RAID level too, but it will be very long explain each of them, thus I only summarized those that are commonly used.

Server = Just Server
- Most server runs on a very specific/custom made hardware, such as HPE ProLiant, Dell PowerEdge etc. The hardware design is total different where everything is either redundant, hot-plug, easily monitored with tons of sensors etc.
- Mostly runs on either Windows Server 2008/2012/2016/2019 etc. or Linux (RHEL, Ubuntu Server) etc. these are server class OS and not those Windows 7/10 desktop class.
- It have a multitude of control such as Active Directory, File Sharing (Samba), Host website (HTTP/HTTPS), even FTP & VPN can be configured to suit the needs.
- Basically its a central hardware that assist in control for file sharing/access and other functions like authentication, verification etc.

Bro, next time before asking a generic questions here, do google up yourself then only ask questions on which part you don't understand, don't expect ppl to spoon feed you.

I am a little bit curious why do you even need that thing anyway. Do you really see my point ? You could go on with such here and that's it. All you need to know what is HDD, SSD and maybe I mean here maybe...something like NVM's and that's it.
