@LinusTech @seagate_surfer Hey those Seagate Ironwolf SSDs sound awesome, I've been planning on buying used server SSDs for my home servers but these are perfect and exactly what I've been waiting for. So happy this is a thing ?

    For server use what's the benefit of "NAS SSDs" (Ironwolf Pro) over normal SSDs (like the 4TB Samsung Evo as an example)? Is it just higher write endurance or is there more to it than that?

    Many SSD controllers and firmware don't play nice with RAID cards or in multi device arrays even when done all in software. These Ironwolf SSDs also have power loss protection which is much more important in a multi device array where inconsistent/incompletely written data can corrupt the array i.e 2 out of 5 SSDs wrote the data in time but 3 out of 5 did not. These do also have higher write endurance but not any higher than a Samsung 850/860 Pro.

     

    I've tried using Samsung 840 and 850 Pros on an LSI 9631-8i RAID card with FastPath and CacheCade upgrade running ESXi but for what ever reason the combination of those SSDs, that RAID card and ESXi caused the SSDs to bug out and lock to 50MB/s write performance. Don't know why, never got it fixed but only happen in ESXi and not under Windows.

     

    For piece of mind and your own sanity you pretty much always want to use something designed for NAS/RAID usage over something that is not. You won't always have problems when not doing so but it can be a right pain when it does happen with no potential fix so you just burned a bunch of money trying to save a few dollars.

    I'm glad you like them! Actually, they are pretty good, they have a similar degree of those designed for Enterprise servers like Exos Enterprise for NAS, in special the Pro version. You can see the features compared at the end of this page:
