Sonnet has released two Tempo PCIe SSD expansion cards.
Sonnet is launching two variants of its Tempo SSD Expansion Cards that allow buyers to mount either one (Tempo SSD) or two (Tempo SSD Pro) 2.5" SSDs. Since the card features a PCIe connector, it enables users to reap the benefit of a SATA3 SSD without needing the requisite SATA3 connector(s) on their motherboard. Sonnet also notes that when mounted in an external enclosure and connected via Thunderbolt, a Mac Pro can boot off the expansion card.
For those interested, the Pro variant allows users to configure the SDDs to run in a RAID-0 configuration for even faster speeds.
At the time of writing MSRP pricing is set at €151 for the Tempo SSD and €303 for the Tempo SSD Pro. No word on availability.

Want to store SSDs? Buy a $0.10 piece of velcro.
Need SATA3? Spend about a third of the price of this piece of stupid device on a new motherboard.
Dumbest thing ever. Why did they develop this? There's zero application for it.
