Traditional Architecture
CPU -> PCI-E Bus -> SCSI/SATA HBA -> Raid Controller -> Disks
Fusion-IO Architecture
CPU -> PCI-E Bus -> ioDrive

SSD itself is a great technology, it has no moving parts, no spinning drive heads, no noise and produce very little heat. But......
SSD has a lifespan, SSD can wears out. According to Fusion ioDrive specsheet, 80GB model have wear levelling of 24 years, 160GB model have wear levelling of 48 years and 320GB model have wear levelling of 16 years. It currently also only supports RHEL, SLES and Windows. The ioDrive is also NOT BOOTABLE device.
Well, at least Fusion IO has a great start. I am keeping my eyes on this company.
Comments are welcome.
