RAID0 with SSDs

[Hooverdan (Dan W.)]

@jpff, I’m sure @Tex1954 can help you out with some viewpoints on SSDs, their durability, speed benefits, as he’s been burning through a few with various experiments, for example this one:

First of all, the reason I like BTRFS so much is because it uses the Copy-On-Write technique rather than a journaling file system: Best Explanation Quote From COW vs. Ext4 "When data is overwritten in an ext4 filesystem, the new data is written on top of the existing data on the storage device, destroying the old copy. Btrfs, instead, will move overwritten blocks elsewhere in the filesystem and write the new data there, leaving the older copy of the data in place. The COW mode of operation br…

Fundamentally, as long as you accept the risk of still losing something (which can happen even with old style HDDs obviously) and have a backup strategy in place, irrespective of hardware approach, then this can work. The questions I would have:

• Can your server motherboard and network components handle it (e.g. 10Gbps network adapters, etc)? Otherwise you will not be taking full advantage of what RAID 0 might bring you in terms of speed since e.g. your network will always be saturated before the read/write capacity of your drive is reached.
• What is the use case that you have (if you’re inclined to share) that would require a massive increase in storage performance (e.g. video editing storage, game server, etc.)?
