The Toshiba MK01GRRB/R is a top-flight enterprise HDD Series that comes in a surprisingly small form factor. Today we are testing the 147GB version, the MK1401GRRB that is in the same product line as the MK3001GRRB/R, which is the 300GB bigger brother. While 300GB might not seem to be a huge amount of capacity, for a 2.5" 15,000 RPM drive, it the highest available at the time of writing.
This small form factor allows for 2.5" HDDs such as the MK1401GRRB to provide more performance in higher density enterprise HDD applications. Increased storage density leads to less space and cooling requirements. This reduced footprint requires less rack space and floor space to provide more performance than 3.5" form factor HDDs.
Every square foot of space is crucial in datacenters, as it has to be cooled, raising the overall power requirement for the data center. One of the greatest aspects in utilizing 2.5" hard drives is the lower wattage requirements than their 3.5" counterparts. Lower wattage results in less heat generation from the device itself. Toshiba has also integrated enhanced idle spin-down power states to reduce power consumption further.
And then we come to performance. Operating at 15,000 RPM places these HDDs at the top of the pack when it comes down to sheer performance. 15K drives provide a great combination of speed, capacity and agility. With highly random workloads becoming more commonplace as virtual machines proliferate in the data center, hard disk drives that can provide increased performance are in high demand.
