Help me decide!! RAID0 vs. RAID1 vs. RAID5

So I just finished building my rig and I have 1x 250GB SSD and 3x 1TB HDD. I plan to do one of the following as my initial setup..Please advise on pros/cons. I will be using this rig for gaming and storing lots of docs/photos(~1.5TB) I do NOT have an emphasis on ability to network out my files, I DO want to protect them. I would like to save money here if I can do so responsibly; $300USD is the most I would be willing to spend if I were to add onto what I currently have..


PLAN 1

250GB SSD(C:/): used for Win7 Pro OS, Microsoft Office365, and a couple of fav. games.
3x 1TB HDD(D:/): setup in RAID0 for faster access to a "single" 3TB HDD
*I have plans to purchase a separate NAS within 6mo to provide backups and redundancy. This NAS will be setup in RAID5, replacing my internal RAID0 build.*


PLAN 2

250GB SSD(C:/): used for Win7 Pro OS, Microsoft Office365, and a couple of fav. games.
2x 1TB HDD(D:/): setup in RAID1 to provide immediate redundancy(I know that using this RAID will force me to give up a HDD).
1x 1TB HDD(E:/): separate from my RAID, I will partition this into 500GB(Games), 250GB(docs), 250GB(photos).
*will NOT be purchasing a separate NAS down the road, but will eventually replace 1TB HDDs with 3TB HDDs as cash flow comes in. Will use a HDD, purchased down the road, to store backups*


PLAN 3

250GB SSD(C:/): used for Win7 Pro OS, Microsoft Office365, and a couple of fav. games.
3x 1TB HDD(D:/): setup in RAID5, offering redundancy more storage space than Plan 2's RAID setup(I know this will cost me ~1TB of space). Backups will be stored in this RAID.
*Eventually I would like to replace this trio of HDDs with 2TB HDDs down the road.*


PLEASE GIVE ME YOUR INPUTS! I WOULD LIKE TO BEGIN THIS CONFIGURATION TONIGHT IF I GET ENOUGH RESPONSES TO MAKE A DECISION :)

    Do you have a solution?
  3. Plan 1 is asking for trouble with the Raid0 setup
    Plan 2 is too complicated
    Plan 3 is ok, just don't use RAID5 in place of a good backup. It's only useful for saving time if/when a disk fails because you will still have access to your files.

    RAID-0: High read and write performance for larger data sets. Capacity is the multiple of the capacity of the smallest drive in the RAID and the number of drives in the RAID. If one drive dies, all data is lost. Requires at least 2 disks.

    RAID-1: Very high read performance for all data sets, standard write performance. Capacity is the same as the smallest drive in the RAID. As long as one drive has not failed the RAID's data is intact. Requires at least 3 disks.

    RAID-5: RAID-0 level read performance, but terribly slow write performance. It's recommended to use RAID-5 in conjunction with a battery-backed RAID controller so that write-back caching can be enabled. Capacity is the multiple of the capacity of the smallest drive in the RAID and one less than the number of drives in the RAID. RAID-5 can tolerate a single drive failure at a time. Requires at least 3 disks

    I understand RAID 0, 1, and 5. I created those plans based on the equipment I have on hand. What would you do if you were me? It seems RAID5 is best. Maybe I could go with that and have an external HDD that I perform routine backups to as well? Whats your ideas?

    Just set up a automated backup scenario, to a 2 or 3GB drive.

    SSD = OS and applications. Once it is set up to your liking, make an image of that. Save to another drive. Update once a month or so.

    Docs/Photos (these live on one or more HDD's.)
    Set up an automated folder/file level backup.
    SyncBack Free does this easily. Copies anything new or changed to another drive, on a schedule. Maybe every 12 hours.

    RAID scenarios are great, if and only if you really, really need 24/7, no downtime, absolute continuity of operation.
    As in running a webstore or something. If a drive dies, sales can still continue, and you continue to make money.
    For a gaming PC? Far too much work, hassle, and risk of fail.

    But any actual business will also have an actual, regular backup scenario.

    I tried to post earlier but apparently it got swallowed. I do like plan 3 (if RAID5 isn't too much of a pain to setup). Just make sure you are using a cloud backup service or backing up to an external drive regularly.

    I don't mind setting up RAIDs. I have a decent RAID controller so I'd like to utilize it. I am teetering back to Plan 2; OS, etc. onto the SSD, Setting up 2 of 3 HDDs into RAID1, and since HDD 3 of 3 is the odd man out, it will be used to keep backups of (RAID1 docs/photos) and restore points (of SSD's OS and Apps). HDD 3 of 3 will be scheduled to back up weekly to my personal Cloud storage thats in my office for additional safekeeping.
    That way I have redundancy in RAID1 and 2 separate locations for my backups/restore points. How does that one sound? Over the next few months I can buy 3x 3TB HDD (WD Black series) and replace the smaller 1TB HDDs allowing for increased storage space.

    Sounds like a good option as long as you don't mind the complexity.

    Why not both? Create a matrix RAID

    Split the 1TB drives down the middle into a 3x500GB 1.5TB RAID-0 volume for performance, and a 3x500GB 1TB RAID-5 volume for redundancy. If one of the drives fails you'll lose the RAID-0 portion but you'll be able to rebuild the RAID-5 portion.

    Plan 3, with an additional 4th 2 TB drive for backup.

    I don't get why people just post something is not true abut RAID5/6 - It was an issue with parity calculation 20yrs ago, where the IO processor was not powerful as today.
    Current RAID5 and 6 with 12x 3.5" SATAIII drives reads/ writes speed IS 1600MB/s+ on PCIe V2, Where SDD and PCIe V3 are used 4000MB/s is easily achieve.

    Where low cost Hardware RAID like SPM934 and SPM393 consistently read and write @ 250~300MB/s.

    So get with the technology :-) LOL
