I don't think you are going to notice a difference between the two in real world use.
However, according to Seagate, the ST31000333AS has a sustaned read speed of 115MB/s while the ST31000340AS is only 105MB/s. On the other hand the ST31000340AS has a Write seek time of <9.5ms and the ST31000333AS is <10.0ms. All other specs seem to be the same. I think I would go with the ST31000333AS if I had to pick.

The crucial difference lies in the platter density.
ST31000340AS - 4 disks, 8 heads, 250GB per platter ST31000333AS - 3 disks, 6 heads, 333GB per platter When everything else is the same, always go for the drive with the greatest platter density in cases like this. Keep the ST31000333AS... |
