[ G01-1631-5YR ] Western Digital Ultrastar DC HC550 WUH721818ALE6L4 18TB 7200RPM 256MB Cache SATA 6.0Gb/s 3.5" Datacenter Hard Drive (Certified Refurbished) - 5 Year WarrantyWD Ultrastar DC HC550 18TB HARD DRIVE WUH721818ALE6L4 delivers the world’s first hermetically sealed, helium hard drive, the Ultrastar® He10 for massive scale-out envi- ronments. Why does helium make a di erence? Helium has only one-seventh the density of air. Replacing air with helium inside a hard drive dramatically reduces the turbulence caused by the spinning disks, cuts power consumption and results in a lower temperature within the disk drive.
The reduction in turbulence for the spinning disk allows WDto deliver a seven-disk design in a traditional 3.5-inch form factor. In addition to being the world’s first helium-filled hard drive.
