It may be worth pointing out with SSD's as journals that "wasted space" is not necessarily a bad thing. First, unless you buy tiny SSDs, which generally have poorer performance characteristics due to fewer chips, you will be limited by IOPs and latency, not available space. Second, due to SSD wear leveling algorithms, any wasted/unused space that never gets accessed translates directly into longer life and that is no bad thing.

For anything. Ever. The Kingston SSDNow E100 series are the only Kingston products to ever pass our internal qualifications, and appear to be pretty decent. That said, our production Ceph clusters are all Intel all the time. SSD vendors that are not Intel pretty much exist for the sole purpose of keeping Intel honest.
