There are many special hard dics for servers.
What is the name of it?

There are more than one. All major manufacturers have enterprise rated lines.

The way you ask: none. Enterprise hard disks are not a lot more reliable, and without good backups you just risk your business.
Enterpise disks are normally made for running in servers. That is not "I have 2 disks in a home computer" but "I have a database server that is not a joke and needs a lot of IO and runs 24/7". They are FAST (up to 15.000 RPM) and allow a lot of parallel commands (SAS, not SATA - SAS is a network for disks, so to say, you can plug in SATA discs) and more resilient (SATA allows 2 connections which often go through different chips and cables, so even if a controller fails the computer can access the data through the second controller). They oten also come with larger warranties and are rated for 24/7 - normal disks may loose warranty if used so long. They normally get used in SAN scenarios r larger server... like I have a smaller database / virtual server with 24 disk slots which soon gets upgraded to a 72 disks.
But if you run a single disk on a USB external case then - you know - all the talks abou enterprise discs are like putting a formula 1 engine into a fiat panda - makes no sense.
Especially because of one thing: they also fail. You are a lot better off starting to think about backups first. Backups like onto Blue Ray media (128 GB doable) or tapes.
