In our tests, the Barracuda LP 2TB 5.2 watts in idle mode consumes, consumes more than 1.5 W Western Digital Caviar Green its internal hard disk requirements. When writing data to 5.8W power and reading data used its power consumption 6.4W jumped up. Performing a simultaneous read/write operation causes the drive consumes 6.3W. Since the LP Barracuda 2 TB has a constant speed, power consumption was more consistent than the Caviar Green, the drive disk rotates at variable speeds. Overall, the Barracuda uses less power than most LP 3.5″ internal hard drives, but the energy savings are not as important as the Caviar Green’s.

We tested the drive by the transfer of data between it and a 300GB Western Digital VelociRaptor. In these tests, the Barracuda 2TB LP performed significantly better than the Caviar Green 2 TB.

The 20GB hard drive wrote of 3-4GB files with 73.8 megabytes per second (Mbps) and read the same data 79.5MBps. It copies the data from a folder on the hard disk to another at a speed of 29.8MBps. In our small test file with 3GB files of 1 MB, the Barracuda 2TB LP wrote at 50Mbps, look on 76.5MBps and held a concurrent read/write operation at 30.6MBps. These speeds are much higher than the Caviar Green 2 TB, the 10-30 Mbit s read and write was slower tests.

The 1TB Barracuda 7200.12 is the first drive of the 12th we tested generation of 7,200 RPM Seagate Barracuda line had, and it is Seagate’s best chance for a fresh start after firmware problems that plagued their line 7200.11.

The 1TB 7200.12 has much in common with drives from the previous generation of Barracudas: It has 32 MB of L2 cache, 7,200 rpm speeds and SATA 3Gb/s data transfer with Native Command Queuing. The 7200.12 but has only two wheels to reach 1 TB, while 7200.11 uses four.

Basically mean fewer panels higher storage density, which translates into better performance. For example, our recent favorite-terabyte hard drive, the Samsung Spinpoint F1 HD103UJ were three plates, exceeding the earlier Barracuda four plates. So still a two-platter drive will be faster, right?

Yup. The new 1TB Barracuda’s read and write speeds approach those of Western Digital Velociraptor. The Barracuda average sustained reading exceeded our benchmark h2benchw 100MB/s, 7 percent faster than the Samsung, while sustained write speed was impressive 99.3MB/s, almost 14 percent faster than the Samsung drive.

Random access reads, more than 25 percent faster on the Barracuda, were burst speeds 24MB/s faster, and the Barracuda’s PCMark Vantage score was more than 25 percent higher than that of Samsung. In fact, only the Barracuda’s random-access write failure, the Samsung’s-at 15.2ms beat, they are still lively, but no match for the Samsung 9.8ms response time.

The 1TB 7200.12 drive has a list price of $ 150 and a street price of about $ 120, which brings it in direct competition with its older, larger cousin, the Barracuda 7200.11 1.5 TB, which consistently sells for about $ 140 retail for months. The 2TB Western Digital Caviar Green gets $ 300.
