It is relatively easy to replace Raid one drive with a larger Raid one drive. You must turn off your system, and take out the drive, and place the larger drive in its place. Next, you turn on the system, and install the larger drive.
RAID 10
A group of hard drives assembled into a RAID array is often referred to as, well, a "RAID array" a "RAID stack" or a "RAID cluster."
Every RAID level stripes data across multiple drives, which improves performance compared to using a single disk. RAID 0, RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have better performance than a single disk. Other than RAID 0, all other RAID levels provide fault tolerance. RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have fault tolerance.
Check with your motherboard manual (if it has onboard RAID), or check with your RAID controller's manual to see if it supports setting up single drives and not having a raid configuration.
RAID stands for a redundant array of independent disks. Thus, a group of two or more hard disks comprise a RAID, or array of physically separate drives.
That is RAID 1. It uses two drives with identical data so if one fails, you have the other drive. One variation of RAID 1 used by certain controllers is to write as RAID 1 but read more like RAID 0 (but without the striping). That way, you have the write protection of a mirrored set, but can use the two drives to do interleaved reads for a read performance boost.
For Raid 5 all the hard drives have to be of the same speed.
RAID 0 is generally the fastest RAID level. It uses two hard drives at the same time, with each drive sending and receiving different data. The data is usually "striped."
It is a combination of RAID 1 and RAID 0. It takes at least four disks for RAID 10. Refer to A+ at Ch. 6 pages 258.
RAID 1 is the most fault tolerant, as all drives have to fail to lose data.
RAID 0 is the best for speed because it uses "data stripping". That means if one drive fails, all you have left on the other one is useless bits and pieces of your files. That means one drive failing will corrupt ALL your data. If you choose RAID 0, you MUST back up your data at the very least every day. Preferably every hour. Automatic back ups is a good idea anyway. RAID 1 uses "mirroring". When you save a file, it gets saved to BOTH drives. Putting drives in RAID 1 does not make the system faster. That means if one drive fails, the other one will still contain all your data. The problem with RAID 1 is that you only get HALF of the space you bought. For example, if you put 2 drives with a 3TB capacity in RAID 0, you would have 6TB. 2 drives with 3TB each in RAID 1 would mean instead of 6TB, you would only have 3TB. The reason for that is because both drives contain the EXACT same data. RAID 5 is pretty good for speed and if 1 drive fails, you can just replace it and rebuild the RAID 5 array without losing any data. RAID 5: RAID 1: RAID 0: I would create a RAID 0 array to store your files and if you care about any of the files you would store on your computer, a RAID 1 or RAID 5 array (I would recommend RAID 5) to back up your data to. I hope this helps.
There were originally five different RAID levels. However, you can use a number of hard drives to create more raid levels, although this may affect performance.
