Windows 10: RAID-3 on the cheap -- is it possible?

----- What is RAID-3 on the cheap? -----

RAID-3 on the cheap is a 2-drive RAID-0, plus a smaller, 3rd drive. The 2-drive RAID-0 is standard, not anything special. The 3rd drive is a dedicated parity drive. It's the 3rd drive that makes it a RAID-3. But it's not an ordinary RAID-3.

How is it different from ordinary RAID 3? The RAID-0 & the 3rd drive are written only once. The 3rd drive is then unplugged & put away (to be taken out solely to rebuild the RAID-0, if needed -- hopefully never).

Compression is applied to the 3rd drive to halve its size. For example, if the RAID-0 is 2 x 8 TB, the 3rd drive will be 4 TB.

In theory, if the RAID-0 data is truly random & block size is very large, the 3rd drive can be nearly half its usual size. In practice, 1- to 2-percent of the RAID-0 data will be structured, and block size will be the entire RAID-0, therefore, the (compressed) 3rd drive is almost guaranteed to be less than half its usual, uncompressed size.


----- Is there an existing software product? -----

Data Write: The user creates a RAID-0 as usual, no special handling, no special software.

Parity Write: The software reads the RAID-0 & writes a compressed parity stream to the 3rd drive.

Rebuild: The software reads the 3rd drive & uses the decompressed parity stream to rebuild the RAID-0.

Advantage of RAID-3 on the cheap: The 3rd (parity) drive is only half its usual size.

Disadvantage of RAID-3 on the cheap: The RAID-0 must reasonably be treated as read-only (or write-rarely).

The application is home theater. Thus, once it's written, the 3rd drive can be unplugged & put away.


Can Win10 Storage Spaces accomodate the compression needed to realize RAID-3 on the cheap? Or will RAID-3 on the cheap require special software?


Thanks, and Warm Regards,

Mark.

Cheap Photo box that will get the job done

WEll i took on this project for PP hes a hardware reviewer and wants to get the professional looking pics for the Pc parts

Materials:

• Big cardboard box

• a razor

• white material 3 yards

• cone lights

• stapler

• medical tape

• pvc pipe about 6 inches longer than your box

• white paint any cheap finger paint would work

the project I'm guessing will cost me $30 if it works out properly
I will post pictures and step by step as i do it

 

Is it possible to easily setup Raid-1 on this system ?

Get the six core CPU's I listed, at 3.3Ghz per core they will more than handle any calculations you throw at them for years to come, and with matching RAM in tri channel you will have a very strong setup.


My only other suggestion is a full RAID card like the one I listed with SSD's (in RAID 1)for the OS and programs, and then a RAID 5 array for backup and any large files on the board with a offsite final backup

keep us posted. i'll be interested in this as i've been wanting to do one for a while.
