Important Compatibility Notes

• This is a standard 3.5-inch SATA desktop hard drive .
• It does not fit laptop drive bays, M.2 / NVMe slots, PlayStation 5 internal storage, or Xbox Series internal storage.
• Your desktop PC requires both a SATA data connection and SATA power connection.
• For external use, you need a compatible 3.5-inch SATA enclosure or dock with its own power adapter.
• This is a mechanical hard drive, not a solid-state drive; it is designed for large storage capacity rather than SSD-level load times.
• This model uses SMR recording technology and is best suited for backups, archives, media libraries, desktop storage, and lighter write workloads.
• For heavy-write RAID, intensive NAS use, surveillance recording, databases, or constant-write workloads, a CMR NAS or enterprise-class drive is a better fit.
• Your operating system will show slightly less than 8TB usable space after formatting because storage manufacturers and operating systems calculate capacity differently.
