SSD vs. HDD: In Search of Performance

SSD vs. HDD: In Search of Performance

 

By Brian Feller

"I do not fear computers. I fear the lack of them."  Isaac Asimov

For much of the 19th and 20th centuries, the most critical element to the success of any business was a simple equation: Location. Location. Location.  Businesses lived or died based on their ability to select an optimal geographical area. In the first century of corporate Darwinism, those enterprises that controlled the highly trafficked areas with excellent lines of site attracted net-new clients and survived.  Those that did not went the way of the Tucker, Wachovia and Commodore.

With the flipping of the centurial calendar, this underlying ingredient of achievement has segued from one of physical space to a much more binary algorithm:  Data.  Data. Data.  He who has it (faster, broader) wins. Period. The magnitude of today’s data is growing at a scale that would make even Mr. Moore and his law gasp – yet is arguably exceeded by the enterprise’s need to access it anywhere, anytime.  However, similar to how the U.S.’ highway infrastructure was built to accommodate about 1/20th the amount of daily traffic it actually supports, this has created a major performance gap that has seen hard drive-based storage systems lag behind advancements in Random Access Memory (RAM) and processors.

SSD Storage Demands Proper Partition Alignment

SSD Storage Demands Proper Partition Alignment

 

By Koka Sexton

Storage system performance is dependent on many factors, one of which is a properly aligned partitioning scheme. Misaligned partitions cause a significant reduction in the I/O performance of a disk drive through redundant read/write operations and a subsequent reduction in an SSD lifespan by as much as one-third. The introduction of 4K sectors in the latest disk drives creates even more alignment problems for a large proportion of IT administrators. Implementation of enterprise virtual environments and the use of different RAID technologies are also susceptible to misalignment. In most cases, a mismatch between actual physical and logical representations of data causes a significant decay in overall system performance and hardware longevity.

Going Green: Trading Space for Power Protection -- The Power/Density Paradox

Going Green: Trading Space for Power Protection -- The Power/Density Paradox


By Randy Chalfant

Growing demand for capacity in ever-shrinking data center space has motivated some storage vendors to cram as many disks as possible into a single space to manage capacity needs without expanding the storage footprint. As much as some vendors call the problem solved, it’s not that simple. Without proper efficiencies and architecture, high density storage systems can create more problems than they solve and ultimately devastate your business. For some, that comes in the form of reliability issues with poorly constructed storage subsystems. For others, it comes in the form of the power/density paradox that hinders end users from utilizing the very floor space that high density systems were intended to conserve.

Understanding the Difference between the Burst and Sustained Performance of Flash Solid State Disks

Understanding the Difference between the Burst and Sustained Performance of Flash Solid State Disks

More frequently IT departments are looking at Flash as an efficient and cost-effective method of increasing transaction rates and supporting more concurrent users without having to add servers or alter their applications. For executives and administrators unfamiliar with the differences between hard disk drives and Flash, the competing claims and specifications of vendors can easily be confusing, misleading, and sometimes daunting. In this article, we will explain how Flash media is written and erased, and how these processes differ from the equivalent processes for hard disk drives. This will help readers to understand why initial, or burst, performance rates for Flash media may differ from the sustained performance rates that users can expect to see in steady-state operation. By demystifying the technology, users can make more informed Flash system comparisons and better procurement choices to meet their IT needs.

The Future of Data Storage – Its Top Three Issues In-Depth

The Future of Data Storage – Its Top Three Issues In-Depth

In 2008, IDC estimated that the amount of digital information produced worldwide will increase tenfold from 2006 to 2011. Driving this data explosion are devices and applications such as digital cameras, medical imaging and record archiving, digital surveillance, multimedia and customer information systems (The Diverse and Exploding Digital Universe; An Updated Forecast of Worldwide Information Growth Through 2011). Helping enterprises keep pace with storing, securing, managing and governing this content will be a critical requirement for next-generation storage systems.
