Hard Drive

Seagate Barracuda 7200.9 250GB SATAII Picture 7637
Model: Seagate ST3250824AS

  • SATA 3Gb/s with NCQ - Higher through-put and supports Intel Hyper-Threading for increased performance of SATA servers and workstations supporting intensive applications. NCQ also increases reliability in heavy workloads significantly reducing the drive's mechanical wear.
  • 3-D Defense System - Industry's most comprehensive drive and data protection system
  • 7,200 RPM - Higher performance and data through-put
  • 63 Gs operating shock - Robust product for challenging applications
  • 350 Gs non-operating shock - Top reliability and durability during shipment and integration
  • RoHS Compliant - Meets or exceeds all current and proposed environmental standards and legislation
  • 8 MB Cache - Provides high performance with increased data bursting through the interface
  • 2.5 bels idle, 2.8 bels seek acoustics - Super-quiet drive is almost inaudible. Difference between idle and seek can hardly be detected by human ear, making drive operation almost silent.
  • Best-in-class operating and non-operating shock for excellent reliability
  • Industry's leading combination of capacity, performance and reliability
  • Best-in-class idle and seek acoustics for quiet operation
  • Best-in-class SATA feature set enables advanced platform applications
  • Broadest portfolio of drives - one qualification covers all integrations requirements
