WD has added 4 GB drives to its SAS WE RE and SATA WD RE lines of enterprise-class hard drives.WD has added 4 GB drives to its SAS WE RE and SATA WD RE lines of enterprise-class hard drives.

Hard drive manufacturer Western Digital has expanded its enterprise-class storage offerings with the release of new WD RE SAS and WD RE SATA hard drives in capacities of 4 TB, the largest on the market today.

The new drives join current models already offering 1 TB, 2 TB and 3 TB capacities for nearline SAS (NL-SAS), and 250 GB to 3 TB for the SATA line.

"The 3.5-inch WD RE SAS and WD RE SATA hard drives offer the powerful combination of enterprise-class features and superior capacity to meet the growing demands of conventional business-critical environments as well as the high-capacity and performance requirements of cloud and scale-out computing," WD said last week.

WD's RE SAS and RE SATA drives feature dual port, full duplex connectivity, ideal for leading business-critical enterprise topologies. They also include NoTouch ramp load technology, meaning that the recording heads never touch the disk media so that there's significantly less wear to recording heads and media, and better drive protection while in transit.

The actual specs for the 4 TB NL-SAS WE RE drive include a rotational speed of 7,200 RPM, a 32 MB buffer size, and a sustained transfer rate of 182 MB/s through a SAS 6 Gb/s connection. The 4 TB version of the SATA WD RE drive features the same rotational speed, but a larger buffer size of 64 MB. This drive also fully utilizes the SATA 3 interface, offering a max transfer rate of 6 Gb/s.

"Given the insatiable need for storage capacity across all market segments, WD is offering both SAS and SATA interfaces for the WD 4 TB RE hard drives to best support both private and public clouds," said Doug Pickford, senior director of business marketing for WD’s enterprise business unit. "WD continues to pioneer the capacity-optimized 3.5-inch market segment, in particular, and the WD RE SAS and SATA 4 TB drives are designed, tested and optimized for enterprise storage and applications, enabling 33% greater capacity than previously available drives."

WD said these new enterprise-class drives are "planet friendly," as they're RoHS compliant and feature halogen reduced components. The 4 TB models also consist of five 800 MB platters each, and can enable a massive 2.4 PB of available storage when used with 10 4U, 60 bay enclosures. They also have the highest level of reliability, with 1.4 million hours MTBF for the WD RE SAS, and 1.2 million hours MTBF for the D RE SATA model.

Available through select distributors and resellers, the 3.5-inch WD RE SAS and WD RE SATA hard drives are covered by a five-year limited warranty, the company said. Here's a list of prices for the SAS 6 Gb/s and SATA 6 Gb/s models (model, capacity/interface, price):

WD3001FYYG -- 3 TB, SAS 6 Gb/s – $369.00
