Access "Weighing the risks of 1TB drives"

Published: 20 Oct 2012

One terabyte SATA and SAS drives are here. And when larger capacity drives come to market, people always cram them with data. That being said, what are the implications of storing that much data in one place? The risk is the same as it ever was: data loss. However, storing a terabyte of data in one place certainly makes the risk of data loss more acute. Experts agree that it's very important to match these drives to the right tasks. For now, it looks like that's still secondary storage. "When it comes to nearline storage, its all about capacity," says Willis Whittington, senior manager of market development at Seagate Technology. And while Whittington was unwilling to comment on specific release dates for Seagate disks larger than 1TB, he did say that "You can expect to see a 40% to 50% increase in aerial density from generation to generation." With disks this large, rebuild time for failed drives is a legitimate concern. That's why RAID 6 is often recommended, as it protects against dual-disk failure. However, "RAID 6 is duct tape," says Greg Schulz, ... Access >>>

      Web services for storage? It's already happening

    • Hot Spots: Web 2.0 storage: Challenges and choices by Bob Laliberte

      Web 2.0 tools and strategies hold many potential benefits for businesses that deploy them, but their requirements for rapidly scalable storage and access, as well as persistent data, pose significant challenges for the IT staffs that need to build and manage the infrastructure.

    • Best Practices: Tackling data migration

      Data center projects often involve migrating data, which is frequently a painful process that can lead to unplanned downtime and outages. It's time to adopt consistent, repeatable migration practices. Selecting the right approach is highly dependent on infrastructure limitations, data and platform types, time constraints and staff capabilities.

    • Storage Bin 2.0: Virtually changing everything

      Server virtualization drives storage growth and dramatically drives the proliferation of storage networking. This is enabling the re-invention of how we manage, protect, store and access information.
