RAID is being offered as an option on a laptop I'm purchasing. How compatible is it with linux?

Should I avoid it since I'm not a computer expert?

You might find the following articles helpful ....

... never had a use for RAID personally, so I've no practical experience of working with it.

Thank you!

I also don't think I have much real need of RAID. Who doesn't want more power and speed? But I can't justify taking on and planning for the disadvantages. Your first link is from 2009 but I haven't found any newer articles that contradict it.

 

https://www.dedoimedo.com/computers/linux-raid.html:

"The problems with RAID are directly related to their advantages. For instance, while RAID can improve performance, this setup necessarily reduces the safety of the implementation. On the other hand, with increased redundancy, space efficiency is reduced. Other possible problems with RAID include:

  • Increased wear of hard disks, leading to an increased failure rate.
  • Lack of compatibility with other hardware components and some software, like system imaging programs.
  • Greater difficulty in performing backups and system rescue/restore in the case of a failure.
  • Support by operating systems expected to use the RAID."

As far as I'm aware, the basic principles of RAID arrays have not changed in any meaningful way, so despite its age, the dedoimage tutorial is still probably the best one I know.

 

Quite honestly though, with the efficiency and size of modern disks, IMO, RAID is probably irrelevant to the majority of "ordinary" computer users, and introduces an additional level of complexity that most people are not comfortable dealing with.

You can setup a software RAID right in the Ubuntu Server install. Works pretty good too. I have it on my server. But for a laptop, I don't see why you would need it. Just use an external for backup purposes and such.

Noted. I'm not ready for a server yet, but I have started to really want one lately. I might actually try in the next year or so. We have multiple laptops in the house now, and it all seems very insecure. Especially as two are running windows.

Servers are fun. Allows you to play around with different things. I haven't hooked mine back up yet, but it's got a samba share running so I can save files and pictures to it from any PC. I also ran a voice server for friends to connect to for game playing. But discord works nice for that now and I don't have to expose a port.
