Nope. Given the same situation (no Samsung 80GB 7200s — our best-selling drive) I'd still apply the same solution: pay the $40 extra to use Samsung 120GB units.
But, to save you spamming the thread with yet another question, Tea, if there were no 80GB Samsungs and no 120GB ones either, then I'd have to decide between Samsung 160GB units and another brand of 80GB.
That's tougher. The reality is that the price difference between an 80 and a 160 is probably too big to bridge. So yes, I'd consider Seagate in that circumstance. But I'd also consider Hitachi, and possibly Maxtor.
Guess I'd be advised by the crew here as to which of these would make the best substitute. (Well, by those of the SF crew that handle a statistically significant number of drives at least. Less than 100-odd units just doesn't provide any useful information.) (I was going to add "IMO" to that last, but it's not actually "opinion": I have some training in statistics and it's simple mathematical fact — but writing "IMSMF" might not be very meaningful!)
In the end, faced with a double-step shortage (no Samsung 80 or 120GB drives), I think we would deal with it using a two-part policy:
(a) Offer customers a Seagate/Hitachi/etc drive at the regular price
(b) Offer them the choice of upgrading to a Samsung drive at whatever extra cost stepping up to a 160 involves.
I'd buy in a box each of Hitachi/Seagate/etc 80GB drives, and of Samsung 160s. My guess is that ~50-60% of people would pay the extra. I would, of course, recommend that they do so.
(Or, if I could get Samsung SATA 80GB drives, I'd just use those instead wherever possible.)
-----------------------------------------
So where does that leave Seagate? So far as my business goes, it leaves then in with a rough chance of picking up any emergency shortage trade we happen to have. Pretty small beer, but better than none at all. That's an improvement for them. Prior to this announcement, I had them in the same category as Western Digital: not even on the radar.
