I am looking at using this as it is built in.  If I create a storage space of for arguments sake 20TB then down the line I find it wasnt large enough, can I expand it to say 40TB or do I need to create a new pool.  Probaly looking in wrong places but I am guessing it is possible to increase but not decrease size which would be logical.

I think that's right, with a thin provisioned space.

I use storage spaces with ReFS, not in that way. I use 2x4TB disks, with ReFS for disk integrity, and in a mirror. I didn't bother to set the sizes larger than the disk, if they fill I'll replace them.

There are a few threads about storage spaces and ReFS on GZ.

Sort of related, but actually unrelated, I came in here to ask another question about storage spaces.

I am intruiged by the possibility of using striping on higher speed flash memory, to emulate SSD speeds on a windows tablet.

Namely something like this:

eMMC
+MicroSD (higher than 100 MB/s sequential read)
USB 3.0 flash nub (high speed, higher than 100 MB/s sequential read)

Until recently those speeds have been uncommon or impossible. And you need to install a script or a special driver to get removeable storage to get recognised as permenant - which is probably something you'll need to do (to make them dynamic, and have the windows system seperate - unless your eMMC is bigger? all new area for me)

But, assuming you can make these all dynamic disks and make them appear as permenant -

1) Can you strip them in windows 10 using storage spaces?
2) What kind of speed gains will you get with stripping. Is it basically more or less additive? If so, you could definately get up to SSD speeds, possibly beyond in some metrics...
3) I believe you have to leave the windows and boot system on a seperate partition. Correct?

As a fan of smaller tablets, that likely won't get SSD for awhile, it seems like a viable and cheap enough solution especially at around 64gb each drive, to get better caching, installing, loading etc, as well as a larger total pool of space (especially given I already have the microSD)

It would be cool to get some feedback from some folks with more experience using storage spaces to stripe...:)

I wouldn't bother on a tablet. Can the processor really handle more data more quickly, and if so does the UI make it easy for you to do whatever you're doing? What are you doing that requires that much speed / effort?

I will go ahead create a storage pool of 4 x 2TB drives using ReFS and parity on Windows 10.  Then a year or so when becomes full hope it will be able to be expanded by adding extra drive or removing one and installing larger hard drive.

OP : You might want to consider DrivePool.

http://stablebit.com/drivepool

It's well worth the price even though storage spaces comes free with Windows.

I already have drivepool on my server and love it. 
   Since Windows 8 on comes with Storage Spaces I thought would use that as another type of backup and I dont have to pay for yet another license.  I believe with Windows 10 storage spaces with the ReFS will continue to improve as time goes by.   And Drivepool all being good if for some reason it goes bellyup then you can no longer activate it. I have had that happen with many other technologies over time.  So I want to give Storage Spaces a try and it is not the main backup but another layer

And a single failure on any of them results in complete data loss.

Performance would be all over the place given 3 devices with totally different r/w speeds and profiles

Boot partitions can't be on a storage space

finally STRIPE, STRIPE, STRIPE. not STRIP.

You use striping when you have a RAID 1 of your RAID 0.

I believe it can handle it yes. Modern tablet processors such as cherry trail and core m are more in the ballpark of slimline laptops. 

An SSD on a PC, speeds up windows caching (and thus multitasking), loading programs, installing, copying. On a windows tablet, its quite viable to play desktop games, load large office documents, have multiple browser tabs open, or multiple programs - all of which could be enhanced by faster disk loads. 

It's also one of the very few performance mods you can conceivably do (apart from, say enhancing the heatsinking).

For my own tablet experience, I do like to multi-tasking, use multi-tabs, and game - and the later can push a tablet to its very limit.

I know, I'd do regular backups (easy enough to do). Boot partitions, yeah I figured.

Not sure what the last sentences mean - do you mean, having a single mirror as well as the three stripes? 

I guess that could be sensible. Would work well even, if one of disks was larger. 

Still assuming that say you have a sequential read of 150 MB/s USB nub, a 115 MB/s microSD and 170 MB/s eMMC - would that mean you get roughly a 435 MB/s sequential read (probably less at guess?)

I'll probably give this all a hack at some point, just want to know as much as I can before I do.

Oh, I see you were correcting my spelling. Well you wouldn't be the first, it's kind of hopeless...:P

I set up 4 x 2TB storage pool with parity on 24th November. 8am November 25th started copying 4TB dvd backups/music and photos to it.   As of 8am 29th November it still has 19 hours to go.   So very slow.  Will still see how it goes when all done but at this time I prefer Stablebits drivepool still

Something's sounds wrong there. I have 2x4TB as a mirror on ReFS with file integrity checking turned on, drives are 7200rpm HGST. I can copy 10GB from my SSD to my 2x4TB in 1 minute, so 1TB in 100 minutes, and 4TB in 400 minutes (6.5 hours).

It could be the different setup has more overhead - what exactly is your setup? 4 drive, 2TB, creating around 8GB usable space, or is it some kind of mirror?

Just 1 120GB ssd for Windows 10 pro os.  4 2TB hard drives setup in storage space pool and using parity. No mirror.  But using ReFS.  After googling it appears to be normal. Some have had better speeds using NTFS instead.
