Platter density has been the crutch of hard drive makers in recent history. Increasing spindle speeds can reduce random access latency, but at the expense of cost and thermals. Improvements in random access performance via increasing spindle speed pale in comparison to what is possible with solid state storage, not to mention that driving motors at speeds beyond 10,000 RPM becomes quite difficult. The focus on increasing platter density is also difficult, but higher density platters can actually lead to reductions in power consumption rather than the opposite (through a reduction in the number of platters per drive). There's also the fact that if you can cram more data on a single platter there's a direct impact on sequential accesses.
Yesterday Seagate announced its transition to 1TB platters with its new 7200RPM-only Barracuda line. The move marked a significant change for Seagate as it is phasing out the Barracuda Green brand, and shifting the focus of the high-performance Barracuda XT.
Read on for our review of the new 3TB Seagate Barracuda.
