Thinking about getting the new Crucial SSD when it comes out. But I don't have SATA 6gb/s whats the best add in card I can get. I have a EVGA 3way SLI motherboard so I should have plenty of bandwidth from one of those slots right?

I purchased the Asus U3S6 add-in card with two internal SATA III (6 Gb/s) ports and two external USB 3.0 ports for less than $30.00. Works in a PCI-e x16, x8, or x4 motherboard slot and it is backward compatible with SATA II and USB 2.0. I did not experience any problems with the card itself. I am satisfied with it.

Please check your motherboard manual or the manufacturer's web site to find out if all of the PCI-e x16 slots still operate with all 16 lanes when all slots have devices. Sometimes one or two slots might be reduced to x8 mode each. It just dpends on the brand and specific model of your motherboard.

EDIT - IMPORTANT - I forgot to mention something. The ASUS U3S6 card is not compatible with all motherboards. It may or may not work with your motherboard. The Asus web site has a list of compatible Asus motherboards. Here's a link to the page:

Click on the specifications tab to see the list.

I have an Asus motherboard which is not on the list. The card worked anyway. :)

The Cruical SSD will work on SATA II ports, just scaled down to SATA II speeds. If spec are out there somewhere...

Instead of upping your system to use SATA III with an add in card, why don't you just get a good SATA II SSD? Try looking a the OCZ Vertex 2 60GB. Probably cheaper than the Crucial (@60GB), and may have higher read/writes on SATA II (285/275).

Or, wait until next month when some new SATA II SSD will be comming out that may be faster than the current SATA II and some SATA IIIs.

An option you might want to consider are PCI-e based ssd's. The PCI-e based ssd's are available with multiple ssd's in a raid 0 array one on card. The drives fit in either a PCI-e x16, x8, or x4 slot on a motherboard.

Here is a link to an excellent technical review of a PCI-e based OCZ RevoDrive X2 published last month by Tom's Hardware:

There is one more thing I should mention. There are some motherboards that have only two PCI-e x16 slots but no x8 or x4 slots. The PCI-e x16 slots are backward compatible with x8 and x4 devices. As long as you only use the primary x16 slot it has all 16 lanes available for the primary slot. That primary slot is usually for a video card. However, if you add a second device such as a video card for Crossfire or SLI or a video card and a ssd, then both x16 slots are reduced to only 8 lanes each. Both slots have to share 16 lanes. The video cards will suffer a slight performance hit of about 2% to 5%. There may also be motherboards with more than two PCI-e x16 slots that also reduce the number of lanes available from 16 to 8 if mutiple devices are used. Please check your motherboard manual or manufacturer's web site for more information about your specific motherboard. Hopefully you'll have all 16 lanes available in all the PCI-e x16 slots.

*** NOTE - I looked at your motherboard specifications. You're in luck. A PCI-e based ssd with multiple drives in Raid 0 wil definitely work providing either your secondary PCI-e x16_2 slot or your PCI-e x8 slot is free.
