Probably. You also have to consider their power consumption. Even if this is an enterprise-version of the Green Caviar, it probably uses up more. Worse, consumer-level caviar greens don't exactly have a good rep.
at 21 canadian cents per gb, this drive is just about 2x more expensive per gb than the 1tb green version. I'd advise consumers against those drives until the prices settle a bit. There is no point in spending twice as much money on storage drives because they are new (unless you are a prosumer with monies)
