I want to replace my 2 250GB SATA drives with a single 500GB

>>58557847
Yes.

I used a PCI-E 1x raid controller before and had two drives, none in raid, just regular AHCI mode.

>>58557847
if you want RAID you'll need more than one drive, if you simply want to move your stuff from two 250GB drives to a single 500GB drive, then yes you can.

>2 250GB
>SATA card

Is your computer really really old? I don't get it. Maybe I'm just ignorant.

Maybe they put them in raid to try and get more speed.

Just make partitions

>>58559761
the whole idea of RAID is to have a data storage consisting of multiple drives, I don't remember which RAID setup does what, but some boost read/write -speed and others exist to avoid losing all stored data when a drive breaks, using multiple partitions on a single physical drive doesn't provide either one of these.

>>58560272
yea it does.. trust me, what you want is 4 partitions in raid 6

>>58557847
Plug in 500GB drive
burn Gparted ISO to USB stick
copy partition from RAID array to 500GB drive

if it's a software array then just copy the volume(s) over

RAID 6 with four partitions, in other words a situation where you can lose two partitions without losing data, ok, let's think about how that works; four partitions on a single disk, how does a partition fail? Unless the partition gets somehow corrupted the only way for a partition to fail is if the drive it's on breaks, and if the drive breaks you just lost *ALL* four partitions.

>>58560979
actually, before you say that partitions are more likely to become corrupted than the disk is to break, let's use this analogy: you have eggs (partitions) and a basket (the drive), I say "don't put all eggs in one basket (all partitions on a single drive)", and you say "meh, the eggs will get spoiled before anything can happen to the basket anyway"

Yeah, it's 10 years old and the harddrives are failing. Other than that it works fine for what I want.

Femanon here.
I used the calculator on my iPhone 7 and it turns out 500gb is the same as 2 x 250 so it should be compatible

you need to read into this a bit more before advising others on how to preserve their data.

You need to fix the boot loader on the new 500gig disk after cloning your partition(s)

that's what, two, three commands in console (command prompt in Windows, shell in unix)?
