Western Digital Ultrastar 18TB SATA3

Hard Drive

Western Digital Ultrastar 18TB SATA3 Picture 63342
WD Ultrastar drives are oriented toward data center use, with a focus on both performance and reliability. They use the SATA 6Gbps interconnect and spin at 7200rpm, and this 18TB model has more cache (512 MB) than some of the smaller sizes. Reliability is ensured with dual actuator head positioning, RAFF for vibration protection, and TLER to help avoid drives dropping out of arrays (RAID). Even though they are aimed at data centers and other enterprise applications, the features these drives have make them excellent options for users who need high capacity, reliability, and performance.
