When our engineers first began testing the Seagate 6TB nearline drives, they had to double-check the results of their benchmarks because they were so surprised at the performance levels they were reaching.  The results were absolutely amazing for a drive of this capacity.  Combining the levels of performance, capacity, and reliability make for an instant success story for our customers when they are measuring their return on investment.  In the words of one of our product engineers ‘This Thing Rocks!’”

Todd Swank, Senior Director of Product Marketing, Servers Direct 

The performance of the Seagate 6TB enterprise product is quite impressive. There is a significant and measurable edge in various operations versus competing 4TB disks; in comparative testing, the Seagate 6TB product out-performed in the range of 48-63%. With these metrics we can spec the 6TB HDD to meet our objective to advance our customers’ hardware configuration and, in turn, improve their application’s performance.“
