One assumes that it was the relative success of Quantum's low-budget offering that is responsible for Maxtor's decision. It wasn't just in Australia, as I recall, but worldwide, and it applied only to the ultra-cheapo 4400 RPM drives - the Fireball LCT, which was the successor to the infamous Bigfoot.
To me it say that Maxtor have decided on the direction that they are going to take over the next few years: low-budget bottom of the market. This fills me with concern for them - not for me, as I would be very surprised to see all the other manfacturers follow suit. Indeed, if any of them have really reliable product (as Samsung most certainly do) I expect that the Maxtor competitors will be delighted that Maxtor have just shot themselves in the foot and handed over a huge marketing advantage. Remember, if you have a really reliable product, your RMA costs are low, and it costs you little to have that 3-year advantage.
But is the market direction thing that concerns me most. This is a giant signal that Maxtor are going after the bottom end of the market, that they are planning to compete with Seagate, Samsung, Western Digital et al on price and ship lower-standard products than they have done in recent years.
And we all remember what happened the last time Maxtor cut their prices and their quality and went after the low end of the market, don't we. They went broke.
