IT@Intel Brief Intel IT IT Best Practices Solid-State Drives and Employee Productivity July 2011

Validating the Reliability of Intel® Solid-State Drives Benefits of Intel® Solid-State Drives •87 percent reduction in annualized failure rate decreases IT total cost of ownership. • 4x faster I/O performance increases employee productivity. To enhance employee productivity while reducing IT total cost of ownership (TCO), in2009 Intel IT made a strategic decision to standardize on mobile business PCs equipped with Intel® Solid-State Drives (Intel® SSDs). Early TCO calculations using data from solid-state drive (SSD) manufacturers indicated that we could reduce TCO due to 1 greaterreliability compared to hard disk drives (HDDs). In a yearlong study of more than 45,000 SSDs deployed in our mobile business PC fleet, we validated that Intel SSDs provide an 87 percent reduction in the annualized failure rate compared to HDDs—which supports our early TCO analysis. See Figure 1. Intel SSDs offer significant performance and support benefits, particularly when combined with Intel® Core™ i5 vPro™ processors and Microsoft Windows 7*. Users appreciate improved system performance, greater mobility, and enhanced productivity and efficiency. From IT’s perspective, Intel SSDs offer greater reliability, better build performance, and lower overall TCO than we can achieve with HDDs. 5% 4% Lower is Better 3% 4.85% 2% 1% 0% 0.61% Hard Disk Drives Intel® Solid-State Drives Annualized Failure Rates Figure 1.

Intel internal measurements, 2008 and February 2011. IT@Intel Brief Benefits of Improved Drive Reliability Reducing drive failures significantly increases employee productivity and reduces IT costs. For this reason, Intel IT proactively monitors and then repairs or replaces drives that exhibit signsof potential failure. For employees, improved drive reliabilityresults in: • Fewer unpredictable and inconvenient outages • Increased productivity and task completion • Reduced potential for data loss • Less time spent recovering data and reconfiguring mobile business PCs For IT, improved drive reliability leads to: • Fewer support calls • Less Service Desk time spent on drive repair and replacement • Decrease in costs for drives with expired warranties • Reduced costs for data recovery on failed drives We consider lowering the annualized failure rate to be the primary factor in reducing TCO. To help us determine how much we could reduce TCO by replacing HDDs with Intel® Solid-State Drives (Intel® SSDs) in our mobile business PCs, we worked with the Intel SSD product group to develop the Client IT TCO tool, which is now available online at design/flash/nand/index.htm. IT organizations can enter their own data into the tool to get a sense of how much they could reduce their TCO by transitioning to Intel SSDs. Background In 2007, Intel IT evaluated replacing HDDs in our mobile business PC fleet with Intel SSDs. As a new technology, Intel SSDs required higher upfront costs compared to HDDs. However, we anticipated that improved employee productivity and mobility plus reduced TCO could justify these costs. We assumed that SSDs would deliver better reliability Read the full IT@Intel Brief Intel IT IT Best Practices Solid-State Drives and Employee Productivity July 2011.
