Fujitsu Launches New Enterprise Class Hard Drives

Next news
3:00 PM - November 17, 2008 by Steve Seguin

Fujitsu has announced two new enterprise class hard disk drives that offer a blend of performance and low-power consumption.

Fujitsu has announced the launch of its new 2.5-inch MBD2-RC and MBE2-RC series of 10K and 15K RPM 6 GB/s Serial Attached SCSI (SAS) enterprise hard disk drives. The new drives use perpendicular magnetic recording, which results in twice the storage capacity of the previous generation product and also a reduction in power consumption. According to Fujitsu, “The new series of enterprise-class HDDs boast best-in-class power consumption and are the first enterprise drives from Fujitsu to be halogen-free.“ The new drives also offer a 60-percent increase in maximum internal transfer rate and use a fast 6 Gb/s SAS interface.

The MBD2-RC series features a rotational speed of 10,025 RPM and comes in two storage capacities: 147 GB and 300 GB. The 147 GB MBD2147RC drive uses a single disk and two heads, while the 300 GB MBD2300RC drive uses two disks and four heads. Both drives also feature the SAS-2 interface, a maximum data transfer rate of 600 MB/s, a 16 MB buffer size and an average latency of 2.99 ms. Typical idle power for the MBD2-RC series ranges from 3.2-watt to 3.4-watt, which is a 28-percent reduction compared to previous generation models and up to a 74-percent reduction compared to current 3.5-inch 15K RPM offerings. The MBD2-RC series has a typical idle noise rating of 29 dB and comes with a 5-year limited warranty

The MBE2-RC series features a rotational speed of 15,000 RPM and comes in two storage capacities: 73.5 GB and 147 GB. The 73.5 GB MBE2073RC drive uses a single disk and two heads, while the 147 GB MBE2147RC drive uses two disks and four heads. Both drives also feature the SAS-2 interface, a maximum data transfer rate of 600 MB/s, a 16 MB buffer size and an average latency of 2.0 ms. Typical idle power for the MBE2-RC series ranges from 3.9-watt to 4.1-watt, which is a 21-percent reduction compared to previous generation models and up to a 68-percent reduction compared to current 3.5-inch 15K RPM offerings. The MBE2-RC series has a typical idle noise rating of 32 dB and comes with a 5-year limit warranty.

The new drives are expected to be released next year, with the MBD2-RC series planned for the first quarter and the MBE2-RC series planned for the second quarter.
