Higher Reliability and Better Performance:
2.5-inch drives are designed for environment requiring higher reliability and higher I/O density. The benefits of 2.5" drives are obvious:
1. 70% smaller: Think about the estimated $1000 cost per square foot in an average data center. Now you can install 2.5 times of drives in the same data center footprint.
2. Consumes 40% less power: In addition to cost reduction, less power means a cooler enclosure, and therefore a higher overall reliability.
3. Higher MTBF: High-end 15,000RPM 2.5-inch SAS drives feature a 1.6 million hour MTBF, which is 15 percent higher than the 1.4 million hour by 3.5-inch disk drives.
2.5-inch Drives Are Simply Smaller:
Infortrend is the first to introduce 2.5" drives in external RAID enclosures. Using 2.5" drives allow you to implement more spindles in less than half of rackmount space than using the 3.5" counterparts. More spindles mean higher IOPS performance.
Lower Total Cost of Ownership:
Compact in Size:
SFF 2.5-inch drives are simply smaller than their 3.5-inch counterparts. That means more drives can be integrated in the disk array enclosures. For example, an Infortrend’s B12F 1U enclosure houses 12 2.5-inch drives while the same number of 3.5-inch drives requires a 2U-profile enclosure. This density edge dramatically improves space utilization efficiency.
Power Consumption and Heat Generation:
SFF 2.5-inch drives consume 45% less power than their 3.5-inch counterparts. They run cooler with reduced airflow requirements, which also decrease the chance of encountering thermal issues and the cost on providing airflow ventilation.
Less Vibration When Spinning:
Spinning multiple drives in a RAID enclosure can introduce interference from the seek acceleration by one drive seeking data to another that is writing. The transmitted vibration can cause retries and hence the overall array performance can be affected. In a high-transaction rate and random-access environment with intensive seek operations, the potential performance loss can be mended by 2.5-inch drives. 2.5-inch drives do not generate sufficient vibration during seeks to degrade the overall performance.
