Wait, wait. So using SSDs as FAST writing disks is a load of hogwash? You still need stuff like umem nvram cards? What's the deal with things like Fusion IO then?
the high end enterprise SSDs have supercaps to give them time to flush their write buffers to flash in case of power failure events.
but these drives are way more expensive than the $200 120GB stuff you'll find in the whitebox market.
the whitebox stuff has fast writes because they buffer them, but in case of power failure with pending write operations, all bets are off on your data integrity.
If I understood correctly, SSD's, even whitebox are good to place ext3/4 journaling files on keeping ext3/4 partitions on HDD's. Right? I would appreciate real-case scenario advice for cheaper drives, for home and small business applications. Thanks
