Yep. That video was with them opening 4 programs at the same time. I forgot which ones, i think big pic file on photoshop, powerpoint, ie9 and one more. Also they tested that windows boots in 7.9secs compared to 17.5 secs for a hdd.
Also, if you read the review, you can see that the max speed they got from the hdd was ~150-160mbs. Sata II (the older one) is capable of 300mbs. Sata III is 600mbs. Since a hard drive can't even max out sata II, i don't see a reason for spending extra money getting a sataIII harddrive.
