There's not a drive on the market that can sustain higher than Sata1 throughput. The fastest hard drive on the market for desktops is still a Sata1 drive (WD Raptor).

how do you come up with that number?

No, bit/byte
1/8

there are 8 bits (the little "b") in 1 byte (the big "B") you take any bit measurement and divide it my 8 to get your total byte measurement

Does this mean that it's pointless to invest in SATA II?

Calling the Iram a hard drive is a stretch. If your computer is unplugged or turned off for 16 hrs, all data is lost. Also, a lot of applications are larger than 4gb, so they wouldn't even fit on the drive. While it may be an innovative device, it's hardly replacing standard hard drives due to its limited ability.

Only real major thing sata2 has over 1 is the burst rate sata 2 will burst up to 300 compared to 150 by sata 1 the avg transfer rate will be the same.

no it is not pointless. The standard has shifted from sataI to sataII. Higher bandwidth and usually higher throughput. The only problem with HDD technology, is that you had seek times and all that extra stuff. The hdd really is the bottleneck of the entire computer. But I do notice a difference over sataI and sataII (my dad's dell, compared to my once living dell (dad=sataI me=sataII) and there really is a difference
