Requires a non-boot second drive ... so the 99% of developers who are working on a laptop can't use it?

You assign this to a partition, not a drive. Single-drive machines can still use this by creating a partition beyond their boot partition.

Thank you, that makes much more sense.

This is great addition. Unfortunately, games and applications can't count on this being available of course. The mass majority of your home users are not going to add a second partition to their drive(s).

ReFS has had a bug with data integrity streams which means it can actually shuffle around bad data when using multiple disks. To go along with that there was a bug regarding proper logging of data corruption which is applicable to single and multi disk configurations. It was still a problem at the end of last year, but the thread I'd been following isn't active anymore and I haven't had time to find any other updates.

It certainly has advantages over NTFS, but unless this has finally been resolved the data integrity streams aren't one of them.

it's a good practice to install the games in a separated partition. Even Steam has a menu dedicated to this, so i think a lot of people do it.

The main problem with installing games on the system partition, is that the user can fill the partition up and render windows unable to boot, essentially bricking the PC.

There are precisely 8 million and 4 ways to fix this - the first being just boot it. Even a full Windows partition will boot to a point where you can delete some stuff - 'bricking' is a touch alarmist. We had this recently with a new customer that had managed to fill their server C drive while leaving the data drive empty...

ReFS (for me) is a minimum requirement when working with large files. I have a 600TB backup server and because of the data size can only do incrementals forever. A synthetic full backup is not possible on NTFS for time and space reasons. With ReFS I make a synthetic full every night because it uses almost no space and processes very quickly. Win2016 had a SMH default behavior of not freeing unused blocks, but I've not had any issues whatsoever with 2019.

It is not clear to me what exactly is the new stuff here. DevDrive seems to be old news. I have it in 23H2. Its UI and the articles I found about it are very annoying. For instance, it insists in using unallocated space. Why not use any existing partition (i.e. already allocated space) and wipe it on command. Also, does it already use ReFS in 23H2 or that is what's new in 24H2. How can I combine a couple of disks with ReFS to use as a single DevDrive in, say, RAID0 or RAID5? Can I do it with the traditional Dynamic Disks infrastructure with NTFS/ReFS on top?

I believe the preferred method is to use a storage spaces pool. Be warned that parity adds a monster performance penalty and mirror wastes a lot of space.

Glad to see official support for ReFS released. What I'd really like to see next is official support brought back for Deduplication on Windows Pro. W10 Pro had it for a while, then MS removed it. W11 Pro never had it. Plenty of purposes to use dedup without being forced into Windows Server. But they gotta make the big $$$ on Windows Server somehow I guess.

To the average user, the article is English, translated from Sanskrit, translated from Greek, translated to Klingon, translated back to English.

It has pretty much zero relevance or benefit to the vast majority.

Billy the Gamer is not going to split his drive into multiple partitions for this.


People that might benefit...thee and me...already have multiple drives and/or partitions.

My Dell laptop is a bit odd in that it was apparently intended to be offered in a very wide range of configurations. It has a 2.5" SATA bay, an M.2 slot, and socketed RAM. The version I got was under $300 at Walmart with a TN screen. I didn't even know those were still made when I got this. I replaced the screen with a 1080p IPS unit for about $60, and put a TB drive in both the M.2 slot and SATA bays. The whole thing came in for about $550. If I could get the same thing with a more modern AMD APU (it was first generation Ryzen), I'd jump at the chance. As designed, it wasn't intended to be upgraded by the buyer but those willing to obtain the right tools can do it without two much anxiety. How Dell offered such a versatile base platform in spite of themselves is a mystery.

How does ReFS with mirror accelerated parity compare feature and performance wise with ZFS?
From what I've read REFS looks like an overly complicated method that doesn't use a DRAM cache. (Overly complicated in its operation, not setup)
The only potential upside I can see is that REFS runs in Windows versus ZFS only running in linux or freebsd, which could possibly save you money.
Or am I missing something?
