EE25 Series 5400.1 Hard Drive
Seagate EE25 Series 2.5-inch hard drives with RunOn Technology are designed to work in extreme temperatures and tolerate high levels of vibration and shock.
Seagate EE25 Series hard drives with RunOn Technology are designed to work in extreme temperatures and tolerate more vibration and shock than ordinary hard drives. Their small form factor, low power requirements and range of storage capacities make EE25 Series hard drives ideal for use in multiple product applications, including automobiles, industrial PCs, mobile surveillance systems, military and aerospace equipment, and other applications where harsh environmental conditions would cause other drives to fail.
EE25 Series Ultra ATA/100 40-GB Hard Drive
Seagate EE25 Series hard drives with RunOn Technology reliably deliver data, audio and video information under high-vibration, high-humidity and extreme-temperature conditions. These drives utilize the PATA interface and are backward compatible with chipsets using legacy DMA and PIO modes.
