Western Digital is the latest vendor to offer 4TB hard disks, aiming its RE line of drives at business-critical environments with growing storage requirements, including cloud and scale-out computing environments.
Available now through select distributors and resellers, Western Digital's RE SAS and RE Sata drives are 3.5in 7,200rpm units designed to provide the greatest currently available storage capacity and deliver high reliability 24x7 operation in 100 percent duty cycle environments, the firm said.
The SAS drives are quoted at 1.4M hours mean time before failure (MTBF), while the Sata models have a slightly lower 1.2M hours MTBF.
Both types feature 6Gbit/s interface speeds, with the SAS drives available in 1TB, 2TB, 3TB and 4TB capacities, while the Sata models are available at 2TB, 3TB and 4TB levels.
"The Western Digital RE SAS and Sata 4 TB drives are designed, tested and optimised for enterprise storage and applications, enabling 33 percent greater capacity than previously available drives and up to 2.4 PB of raw capacity in a single enterprise rack," said Doug Pickford, senior director of business marketing for Western Digital's enterprise business unit.
Pricing for the new Western Digital RE enterprise drives is quoted at €400 (£318) for the 4TB SAS model and €390 (£310) for the 4TB Sata version.
