Taking Storage to Extremes Seagate® EE25.2 Series™ Drives vs. Other Drives, Flash SSDs Summary: Seagate® EE25 Series™ Drive vs. Standard 2.5-Inch Drive EE25 Series 5400.2 Drive Temperature (Operating, ºC) -30 to +85 Shock (Operating, 2 ms/11 ms, Gs) 300/150 Vibration (5 to 500 Hz, Gs) 2 Altitude (m) -300/+5000 Rotational Speed (RPM) 5400 *Manufacturer's specifications for Seagate Momentus® 5400.3 hard drive Standard 2.5-Inch Drive* 0 to +60 350/Fails Test 1 -300/+3048 5400 Seagate EE25 Series Drive vs. Toshiba MK8050GAC Drive Of course, some would argue that the obvious technical superiority of EE25 Series drives over conventional notebook drives comes as little surprise. The more appropriate comparison would be to a competing vendor's 2.5-inch drive specially built for extreme storage environments. The summary table below illustrates how Toshiba's automotive hard drive stacks up against the EE25 Series drive (superior specifications highlighted). Summary: Seagate® EE25 Series™ Drive vs. Toshiba MK8050GAC Drive Shock (Operating, 2 ms/11 ms, Gs) Shock (Nonoperating, 1 ms, Gs) Seek Time (average, ms) ARotational Speed (RPM) Available Interfaces EE25 Series 5400.2 Drive 300/150 900 11 5400 ATA, SATA MK8050GAC Drive* 300/NA 800 16 4200 ATA only *Manufacturer's specifications for Toshiba MK8050GAC drive These specifications offer a rebuttal to the notion that drives are essentially commodity items with very little to differentiate them from their competition. While the EE25 Series and MK8050GAC drives have some similarities (such as identical operating temperature ranges of -30ºC to +85ºC), further investigation reveals that the EE25 Series drive includes a clearly more comprehensive suite of capabilities for extreme environments. Shock tolerance (both operating and nonoperating), seek time and rotational speed (as well as connectivity flexibility) all underscore the superiority of the Seagate EE25 hard drive. Unlike Toshiba MK8050GAC drives, EE25 Series drives don't impose a performance penalty compared to conventional notebook drives (note Toshiba's substandard seek time and 4200-RPM rotational speed) in order to deliver enhanced ruggedness for challenging storage applications. 3
