Seagate has been keeping busy lately following its unfruitful buyout talks. Hot on the heels of announcing the industry's first enterprise-grade 1TB 2.5-inch hard drive, the company is revealing what it claims is the highest-performance eco-friendly internal drive for low-power PCs, multi-drive home servers, NAS drives, and external PC storage.

The new Barracuda Green 3.5-inch desktop drives won't exactly break any speed records spinning at 5900 RPM but they should still be a tad faster than competing low-power drives. There will be two versions available in three different capacities, one with a 32MB cache and 3Gbps SATA interface 1TB, 1.5TB, and 2TB capacities, and another with a 64MB cache and 6Gbps SATA interface offering either 1.5TB or 2TB worth of storage.

The drives are also among the first to utilize Advanced Format 4K sectors in the desktop segment, which should not only allow for higher capacities going forward, but also stronger error correction. Configuring a system to use 4K can be complex, but Seagate's SmartAlign technology promises to make the process almost transparent to users. Barracuda Green drives replace Seagate's former Barracuda LP line and is available now ranging in price from $60 to $120.
