Seagate Technology, the largest supplier of enterprise-class hard disk drives, on Tuesday refreshed family of hard disks for commercial usage with 7200rpm and 10000rpm spindle speed. The company introduced new enterprise performance (Savvio 10K.6), enterprise capacity (Constellation ES.3) and enterprise value (Constellation CS) hard drives.
“Anyone building storage systems today, whether for cloud specific applications or enterprise data centers, is looking to maximize capacity in the smallest possible physical footprint with the lowest operating costs while ensuring long-term scalability. Our new line of Enterprise hard drives meet this challenge, providing the highest capacity-to-power ratios while ensuring consistent performance and high reliability, making them ideal for use in any data center environment,” said Scott Horn, Seagate vice president of Marketing.
Seagate Enterprise Performance 10K hard drives (Savvio 10K.6) are available in 300GB, 450GB, 600GB and 900GB capacities, come with SAS-6Gb/s or Fibre Channel 4Gb/s interfaces and feature FIPS 140-2 compliant AES 256-bit encryption technology by default. Seagate declares sustained data rate (SDR) of 204MB/s, which is in line with performance offered by 15K HDDs and is 3% faster than closest 10K, 2.5” competitor (198MB/s). The drives support enhanced reliability with improved quality controls and RAID rebuild feature. Savvio 10K.6 uses up to 14% less powered than previous-generation 10K.5 drives and up to 71% compared to Cheetah 15K.7.
Besides introducing new generation of high-performance 10K hard drives, Seagate also split its Constellation 3.5" family of hard drives into capacity-optimized Enterprise Capacity (Constellation ES.3) and cost-optimized Enterprise Value (Constellation CS) families. The new drives also consume less power, improve reliability and boost performance.
Seagate Enterprise Capacity (Constellation ES.3) hard disk drives are available in 500GB, 1TB, 2TB, 3TB and 4TB capacities, come with 64MB or 128MB cache, feature SAS-6Gb/s or SATA 6Gb/s interfaces and use 7200rpm motors. The Constellation ES HDDs offer advanced vibration tolerance and security options, including self encryption. Seagate guarantees whopping 1.4 million hours MTBF and five years limited warranty. The drives are optimized for high-capacity bulk-data storage (RAID), mainstream enterprise external storage arrays (SAN, NAS, DAS), enterprise backup and restore as well as centralized surveillance applications.
"We have had a great deal of success with field reliability on the last generation, Constellation ES.2 and we’ve built upon it is strengths while improving the product reliability from the manufacturability of the drive to it is field functionality. The move up from 1.2M hour MTBF to 1.4M hours is proof of this improved reliability along with our doubling of the load/unload specification from 300K to 600K," a statement by Seagate reads.
Seagate's Constellation CS will generally be competitors to WD's RAID Edition hard drives series with some advanced features, such as instant secure erase option. The Enterprise Value are available in 1TB, 2TB and 3TB capacities with Serial ATA-6Gb/s interface. The hard drives are optimized for such applications as replicated/redundant storage in cloud systems, cloud storage servers, cloud storage arrays, cloud backup storage, direct-attached external storage devices (DAS) as well as network-attached storage devices (NAS). The 7200rpm hard drives come with 0.8 million MTBF and three years warranty.
"The Constellation CS is built as the affordable enterprise drive. It is desktop-based platform so it has got the economies of scale we get with our volumes in desktop drives but it has the added enterprise benefits of RV and enterprise firmware and support. It is s designed to be used in replicated environments – where there are physically more than 1 drive with the same data, often in physically different locations," explained Seagate.
