Western Digital is making changes to some of its storage hardware lines, boosting the capacity to 8TB. Three internal hard drive ranges as well as some external hard drive items will offer 8TB of storage to users, 16TB for certain products that use two 8TB drives in RAID 0, with WD using HelioSeal technology to replace air in the drives with helium, allowing the drive producer to use up to seven platters in a single drive, boosting capacity.
