Seagate EE25.2 Taking Storage to Extremes - Comparison - Page 5

Taking Storage to Extremes Seagate® EE25.2 Series™ Drives vs. Other Drives, Flash SSDs Weight The Seagate EE25.2 Series drive weighs just under 25 grams (approximately one ounce) more than a Samsung 2.5-inch PATA SSD. But reviewing those figures in isolation does not tell the full story. To wit, a Panasonic Toughbook-30 notebook computer weighs 8.4 pounds; in that context, the one-ounce difference between the EE25.2 Series drive and Samsung SSD accounts for well under one percent of the system's weight, an insignificant amount. Summary: Seagate® EE25 Series™ Drive vs. Samsung Flash SSD Weight (grams) EE25 Series 5400.2 Drive 102 Total System Weight (Panasonic Toughbook plus storage device, grams) ~3516 *Manufacturers' specifications for Samsung 2.5-inch PATA SSD Samsung 2.5-Inch SSD* 77 ~3491 Power Consumption Thanks to the power-savings features built into the Seagate EE25.2 Series drive, power use is only nominally higher than that of a flash 2.5-inch SSD. More importantly, the storage device (whether hard drive or SSD) accounts for less than ten percent of total system power consumption. A system's video display and ASICs demand far more power, and are thus the prime determinants of net system battery life. Power Consumption: Seagate® EE25 Series™ Drive vs. Samsung Flash SSD EE25 2.5-Inch Drive (80 GB)* MobileMark Battery Life PATA: 328 minutes SATA: 316 minutes *Figures obtained at Seagate Longmont, CO testing laboratory Samsung 2.5-Inch SSD (16 GB)* PATA: 324 minutes Ruggedness While both drives offer high levels of shock and vibration tolerance, the EE25.2 Series drive can endure a wider range of operating temperatures. To be sure, the Samsung SSD's shock and vibration tolerance is significantly greater, but in reality, such lofty limits are largely academic. In actual use, many other system components would likely fail long before the shock or vibration thresholds of the Samsung SSD were approached, rendering such capabilities essentially overkill.
