Highpoint Announces SATA 6Gb/s RAID Adapter
Rock it, RAID.
Looking for SATA 6Gb/s but prefer your drives in a RAID configuration? HighPoint Technologies claims to be the first out of the gate with its RocketRAID 620 Series - a SATA 3.0 host adapters with RAID 5 capability and backwards compatibility with SATA 3Gb/s and 1.5Gb/s.
These RAID host adapters are based on PCI-Express Gen 2 host interface technology and are designed to optimize storage performance and redundancy with RAID 0, 1, 5, 10 and JBOD. User-friendly features include hot plug and hot unplug to add or remove storage devices; and OCE/ORLM to expand storage capacities or migrate to different RAID levels.
The two members of the RocketRAID 620 Series – RocketRAID 620 (MSRP $69.99) and RocketRAID 622 (MSRP $79.99) will ship mid January 2010.

If you were looking at SATA 6Gb/s, wouldn't the only items that could saturate SATA 3GB/s be SSDs - someone would have to want these in a RAID, I guess, to take full advantage.
HighPoint site says the 620 is 2 internal ports 622 2 eSATA ports, nothing else.
*Buys raid card*
Bah! nobody reads these old comments :
Read the spec on x1, for reason.
the reason above poster has issues, is your dirty bit is failing when windows shuts dow,n the last thing
it does is set the dirty bit in the pagefile.sys. at shut down,. then on reboot, if it is true (dirty) you get , that message (illegal shut down)
that fact will put you on the right track.
WD bundles this card with some HDD.
dont expect blinding speed.
unless
1: old mobo bios cant do sata 2 or 3
2: old mobo has on sata at all.
3: old mobo, like me has the nforce bug, where it can not speed shift to lower sata speeds. nforce560
if you expect this card to upgrade new mobo's you are sadly mistaken, that is not its purpose.
if doing raid, see the 640s etc. (im reading all SSD posts)
