Leopard's Time Machine and Windows Home Server loosed upon your desktop, we know what you're asking the Santa man for: a new 7200rpm 1TB hard drive. The question is, which one to purchase: Hitachi, Seagate, or Western Digital. Well, according to a review over at Hot Hardware, it doesn't matter, much. Those looking for the best price can find the WD Caviar GP on-line for about $0.27 per GB compared to the Hitachi's $0.31 per GB price. Seagate's Barracuda 7200.11 tops the list at $0.33 per GB. That's a big jump in heat, noise, and price when compared to the $0.19 per GB required for a 7200rpm 500GB drive. However, if mass capacity is your priority and available slots are limited, then a 1TB disk will do you fine.
