Is RAID still needed? (programming.dev)

Me and my friend were discussing this the other day about how he said RAID is no longer needed. He said it was due to how big SSDs have gotten and that apparently you can replace sectors within them if a problem occurs which is why having an array is not needed.

I replied with the fact that arrays allow for redundancy that create a faster uptime if there are issues and drive needs to be replaced. And depending on what you are doing, that is more valuable than just doing the new thing. Especially because RAID allows redundancy that can replicate lost data if needed depending on the configuration.

What do you all think?

Reminds me of the days that cdroms were brand new and advertised like indestructible, with photos of elephants walking over it. Having said that I assume SSD disks can break like other hard disks can break, and in that case RAID can save a lot of time to get a computer back up especially when a lot of data is involved.

Had a microsd card literally break in half last week. They're definitely not invincible

Yeah they sometimes get touted as that

Was that a SteamDeck? 🙃

Ok. Coz it is really common for SteamD users to forget removing SD card when didassembling device. Lots of cards have been lost

[–] JusticeForPorygon@lemmy.world 1 points 8 months ago

Actually that's kinda what happened. I inserted the card to test if it was working before I put the bottom back on, but forgot to take it out. When I started screwing the bottom back on I heard a snap and that's when I realized...

Definitely a lot of data lost, but most of it is redownloadable.

Funny. Growing up, I was taught to be extra careful with CDs because the moment you look at them wrong, all your data gets corrupted.
