I'm sorry for such a basic question but do i need raid?

I have been doing some basic research but cant seem to get my head around it i plan on having multiple drives eventually 2 ssd's and 2 hdd's would i need raid to merge the 2 hdd's or ssd's to create a higer storage capsity located in 1 folder for example the C: drive or could i just make short-cut folders. Also is there any advantage with raid other than backing up data to 2 drives over just having short-cut folders

A shortcut link, sure. Each drive gets a drive letter. On my secondary SSD, there is a folder tree for MyStuff. it mirrors what you see under Libraries - MyDocs, MyPictures, etc.Those locations are now the default when I save something to "Documents". Same with Downloads...change the default to somewhere on another drive.

As far as music, for instance. All my music (25GB) lives on a whole different PC across the room. Shared folder, mapped drive letter ("M" in this case0. My music player of choice, Songbird, looks at that drive letter...it does not care that the physical drive is elsewhere.
Same with movies. They...

Trim does not work in RAID mode. And more & more users are finding out that trim does not work in second SSDs used as storage. The only solution that I have seen for a second ssd to have trim working is to load windows on it. Trim seems not to work unless there is an OS (win 7 or 8) on it.

You manually do trim on your drives though. It just will not work automatically.

RAID on the desktop is rarely needed. Far more hassle than it is worth, and more chance of fail.
Also, RAID is not a backup. RAID0 (striped) is more or less merging 2 drives into one. In certain circumstances, it can greatly increase the speed. But with SSD's, that is not needed. They are already blindingly fast.

RAID1 (mirroring) is duplicate data on two drives. Helpful if you really need full continued operation in case of a drive failure. As in if you were running a webstore, and a drive being down = lost sales. Again, not needed on the desktop. And since you are duplicating the data across two drives, it faithfully duplicates and accidental file deletion, virus, or other corruption. The file just happen to be gone from 2 drives instead of just the one. You still need a real 'backup'.

Multiple SSD's and/or hard drives is no problem. I have just that in my main PC at home. 2 x 128 SSD's, and 2 large HDD's.
OS and applications on one SD, working documents on the other. Changing the default location for Documents/Downloads/Music/Pictures is very easy.
The two hard drives hold video, music, stuff like that.

So to navigate between the 2 ssd's easily from a desktop for an example you can just create a shortcut folder?

I think you are lucky. There seems to be a lot of users now that have found out that trim just does not work on their second ssd's. A few threads here at Toms about that too. The last one I read about was two 128GB Kingston HyperX ssd's not in RAID mode. On the ssd with the OS, trim worked but the other didn't. Wiping the ssd's and loading windows on the other for the boot drove, trim worked on that one only. Oh well.

to check if TRIM is on:

From an elevated Command Prompt
fsutil behavior query disabledeletenotify
Results explained below:
DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

To enable:
From an elevated Command Prompt
Navigate to the root of the drive in question (in my case the secondary SSD "G")
fsutil behavior set disabledeletenotify 0

To disable:
fsutil behavior set disabledeletenotify 1

Wait a little bit
Run the first command again to check

I can see it not working if you have whole drive encryption.
Thanks for that link.
