Seagate adds Barracuda Green drives with SATA 6Gbps

Now that’s an interesting addition: low-power "green" hard drives with 6Gbps Serial ATA interfaces. A quick look at Seagate’s website reveals the unlikely presence of two new Barracuda Green models, which feature 6Gbps SATA, 2TB and 1.5TB capacities, and 64MB of cache (as opposed to 32MB for the SATA 3Gbps models with the same capacities).

We’ve already seen 6Gbps SATA implemented in high-end 7,200-RPM desktop drives like the Barracuda XT and WD’s 6Gbps Caviar Black, and it… didn’t affect performance a whole lot in either case. Low-power drives therefore seem like unlikely candidates for the new standard. Seagate is the first to admit that Barracuda Green drives have 5,900-RPM spindle speeds, and it claims a sustained transfer speed for the drives of "144Mb/s"—less than half the potential of SATA 3Gbps, even if that lower-case B is a typo.

On the flip side, I suppose that huge 64MB cache and support for the new SATA standard could result in uniquely fast burst speeds. Provided Seagate doesn’t overcharge for the SATA 6Gbps variants, hey, that might be good enough to justify their existence.

    Ahh, the power of marketing!
    Im sure these will have all over the box “SATA 3 – double the speed” while failing to mention that this (and all other 5400rpm drives ever) are still years away from using all the bandwidh that SATA 1 offers.

    Oh, my goodness, 64MB cache. My first harddrive had 32MB *capacity*. (Yes, MB, not GB.) Now, see that lawn? It’s mine. Get off it.

        Come up here and shovel my driveway and I will toss you a $20 🙂

    All valid points (about the performance), but even though this is totally overkill, these drives will help push the popularity of Sata 6. Which can only be a good thing.

    After having two Seagate 7200.11’s drives fail on the weekend all I can say is, never again. Thankfully the second one died after pulling the data off the raid-5 array onto a WD Black.

      You probably don’t want genocide like that.

      I am afraid that would be no real winners in that contest.
