so I'm completely new to RAID and SSDs and all that good stuff. all i know is that SSDs are faster than HDDs and RAID combines SSDs or HDDs. but does it combine a SSD and a HDD together?

right now i have a Western Digital 1TB 7200rpm and I am looking into buying a Crucial RealSSD 64GB.

How would i RAID them together and what would be the outcome??? would it benefit me in any way?

sorry for asking so many questions but this is the only way I can learn! :confused:
thanks! -ExplorerD
 
Probably won't work all that well. RAID SSD's and you lose garbage collection which means they could wear out and die faster (ie in 7 years instead of a decade), and you don't really gain that much performance because an SSD's speed comes from it's near zero seek times. RAID HDD's has a bigger benefit, faster speed, lower access times but you have no redundancy (talking about RAID0 here)
 
You can't raid together an SSD and a regular hard drive. Too many issues involved. only hdd and hdd or ssd and ssd, but not combined.
 
so if i were to raid my current HDD with a velociraptor 300GB would my computer use my 1tb as a storage unit and the velociraptor as a data reader or what would happen?

You don't understand the idea of raid. Raid 0 combines the drives into 1 big drive, 2 500gb drives end up being 1- 1tb drive. Raid 1 combines the drives to make it look like one drive so you have data reduntancy on both drives. It's only recommended to raid drives that are the same speed and size. Don't raid a velociraptor with a standard hdd or an ssd to with an hdd or ssd with a velociraptor.

I think for RAID you need the drives to at least be the same size.

don't have to be the same size but it should be. If you raid 1 a 80 gb drive and a 120 gb drive, the array takes the size of the 80 drive so you lose 40 gb of the 120. Raid 0 doesn't matter.

so i can put 2 WD 1tb but my question is how does it help my computer?
 
Technnically it don't help your computer. It's all personal preference. Raid 0 is for faster read/write access and raid 1 is for data reduntancy in case one of the 2 drives go out on you. What do you plan on using your system for mainly?

I use it for gaming and also adobe flash. but what i dont get is that on your specs it says that you have 2 500gb HDDs with RAID and you also have a SSD?:confused: how does that work?

The ssd is for the operating system, and he has a RAID0 array for his storage (2 x 500gb disks).

Exactly as he described.

Good thing you pointed that out as I don't run raid anymore and forgot to remove it from my sig. I was gonna do it on my new system but didn't set it up like that. In fact, I'm thinking about getting rid of my dual boot XP with 7 and then just use 7 all the time which is on my SSD drive. Once I select windows 7 as my OS, I can be at my desktop and ready to go in like 15 seconds or less. It also shuts down in less then 10 seconds.

so you can use a ssd and a hdd together as long as they arent in a raid. but if i were to get an ssd would i be able to make the hdd storage and make the ssd hold the OS even though right now the hdd holds the OS? how would i go about doing this?
 
Normally you would clone the OS drive to the new drive but in order to get the most out of an SSD then you will want to reinstall windows fresh.
 
ok i use the windows 7 cd to reinstall it into the ssd. now what? do i delete the OS out of the hdd? how will my computer know which one is for storage and which one is for the OS???

sorry about pelting you with questions. I'm trying to get more into computers and how everything works
 
You set the bios to boot to the SSD. Then delete all the windows files on the regular HDD. Then just use it for storage.
 
then all i have to do is reset my wallpaper and everything else will still be there? programs, files, pictures, etc.?
