Running Vista Ultimate x64. XFX680iLT MB q6600, 4 gig ram, 3 WD green power SATA II drives in a raid 5. I have a 1TB WD green power SATA II running through esata. Here is my question. When copying from my eSATA to the raid 5 i'm only getting about 20-25megabytes /sec. Does that sound right. If sata 2 is supposed to be 3Gb, shouldn't my copy rate be faster? Any ideas?
