For content distribution networks to generate more revenue, they must deliver more content. However, storing this additional data can be costly.
Introduce solid-state drive (SSD) technology. Once unavailable to many organizations, today's SSD solutions are designed for use in data centers at the expense of a client PC.
However, many organizations continue to base their storage investment solutions on a single measure - cost per gigabyte. This is a mistake. Today's organizations need to go beyond the cost per gigabyte and explore the many advantages that solid state drives offer over hard disk drives (HDDs). The best measure is total cost of ownership (TCO), which affects all capital and operating expenses.
This is how solid state drives offer a better Total Cost of Ownership (TCO) over the life of the investment.
Technologies such as in-line compression and deduplication can be used with SSDs to increase effective driving ability. In fact, these technologies can increase capacity by a factor of 3 to 5, thus significantly reducing the cost of the required flash drive. Even better, SSDs inherently have more bandwidth and less latency, allowing them to support data processing without compromising performance.
Superior power and performance
An SSD not only offers up to 1000 times the performance of a hard disk, but also consumes one tenth of the capacity of a hard disk. By providing superior performance in terms of data transfer rate, latency and IoPS, SSDs are also ideal for delivering rich content.
File sizes continue to increase with daily use of high-resolution photos and 4K videos. SSDs can meet this need for faster data transfer and sustained high performance over long periods of time.
Although capacity is still limited compared to hard drives, the latest SSDs in the data center have more than enough life to replace 3 to 5 years.
The more energy-intensive server racks and components needed, the higher the cost of electricity. Fortunately, SSDs typically consume less than half the power of hard drives, while providing hundreds of times the level of IoPS. These lower power requirements and reduced heat dissipation can significantly reduce power and cooling costs, especially for frequently used data where the drives are under constant load.
There are several reasons why SSDs promise an average annual failure rate of only 0.5% (hard disk failures can be up to six times more likely). First, they do not require much redundancy to protect data from disk failures. And because SSDs are semiconductor-based, their lifetime can be easily and accurately calculated, which greatly improves the accuracy of TCO calculations.
Enterprise-class SSDs in particular are more reliable than their client counterparts. With built-in redundancy, datacenter-class SSDs can respond quickly and 24/7, even in the event of an unexpected power loss.
So much the better.
When you consider all the capital and operating expenses incurred over the life of an investment, the total cost of ownership is a much more reliable and accurate measure than the total cost of a gigabyte, proving that SSDs offer a higher return on investment.
Do you think the cost per gigabyte is the only measure that matters?
