Comparing performance vs price, some customers would prefer to keep using SATA or SAS SSD for the mean time.

It depends what PCI-E Solid State cards, some of the consumer ones come in at a fraction of the enterprise ones.
So when comparing to Fusion-IO cards like a 160GB SLC ioDrive can cost more than $5000 USD.
Suddenly Enterprise eMLC or SLC solid disk drives for LSI CacheCade are looking better options

There certainly is lots of choose from!
