Looks like there is a formatting problem with old PHPbb... I'll try again:
The whole STxxxxxxLW hard drive story is a bit puzzling at best. As you know, there are currently three models of the Seagate 15K hard drive:
ST318452LW; U160, widely available
ST318432LW; only available at Harddrive.com for $240.00
ST318453LW; U320 15.3, not available at of this writing.
The drive that Harddrive.com is selling is the first generation U320. For this being the case, you will see that the performance specifications is less than acceptable and in many cases, less than the standard ST318452LW U160 flavour. The story behind the ST318432LW is that last year, Seagate only released these first generation (depop), U320 drives to OEM's. As always, some of these first generation drives made it into the retail channel. Hence, Harddrive.com. Because these are first generation and the fact that the performance is less than stellar for an U320 drive, I recommend that you do not consider these for a purchase. Currently, the ST318453LW 15.3 is slated to be released on 09/01/2002 to OEM's. However, the ST318453LW is available, but EMC and Compaq have gobbled up all of them. I assume that only the "A" list SCSI resellers may be on the receiving end for a few of these, when this first shipments takes place. If not, expect to see these in quantity in approximately four to six weeks thereafter.
