New Barracuda 7200.11 and ES.2 offer capacities up to 1TB with 32MB caches

Seagate today unveiled two 1TB hard drives for consumer and enterprise markets – the new Barracuda 7200.11 and Barracuda ES.2. Seagate claims to have “the world’s most advanced family of one terabyte drives” with the new Barracuda models.

The new Barracuda 7200.11 is the follow up to last year’s Barracuda 7200.10, ready to take on Hitachi and Samsung 1TB offerings. Seagate packs the 1TB Barracuda 7200.11 with 32MB of L2 cache, SATA 3.0Gbps and native command queuing support. The Barracuda 7200.11 makes use of four 250GB platters with second-generation perpendicular magnetic recording technology, or PMR. Seagate claims the new Barracuda 7200.11 can sustain 105MB/s data rate.

Even with four platters, Seagate claims the new Barracuda 7200.11 only draws 8-watts during idle and 11.6-watts during seek. Acoustically, the Barracuda 7200.11 generates around 27-to-29 decibels of noise during idle and seeking tasks. As with all new Barracuda generations, the 7200.11 improvements and technologies trickle down to smaller sizes. Seagate also offers the Barracuda 7200.11 in 750GB and 500GB sizes with the same 32MB buffer and PMR technology. Due to smaller sizes, the 750GB drive makes use of three platters while the 500GB drive has two platters.

Seagate’s new Barracuda ES.2 models cater towards the enterprise markets. Although it is similar to the Barracuda 7200.11, Seagate offers the ES.2 with serial attached SCSI, or SAS, interfaces. Seagate has also raised the MTBF rating of the Barracuda ES.2 to 1.2 million hours, up 200 thousand hours from the previous Barracuda ES.

Expect the Barracuda 7200.11 and ES.2 to arrive sometime this quarter in capacities up to 1TB. Seagate prices the 1TB Barracuda 7200.11 with an MSRP of $399. As with other Seagate drives, the new Barracuda 7200.11 and ES.2 come with five year warranties.

Sustained...?

It's annoying how manufacturers use the expression "sustained speed" to mean "fastest possible platter transfer speed" (i.e., the speed on the outer sectors of the drive), instead of the speed the drive can actually sustain over all its sectors. In other words, this 1 TB drive can "sustain" 100 MB/s... if you decide to use only 10% of its capacity.

How true. If the drive could sustain 100MB/s throughout the platter range, it would still take a very long time to transfer data to the drive. We have SATA/eSATA interface, but drive transfer rates are still slow as dirt. We need faster transfer rates for this amount of data to be useful.
