Frequently Asked Questions & Store Policies
Is this drive CMR or SMR?
The Seagate 20TB is 100% CMR (Conventional Magnetic Recording). It does not use SMR, ensuring sustained write performance with zero speed drop during heavy multi-terabyte writes.
Why is helium used inside the drive?
Helium is one-seventh the density of air. Sealing the drive with helium reduces internal turbulence and aerodynamic drag on the spinning platters, allowing 10 platters to fit in a standard 3.5-inch bay with lower power consumption and lower operating temperatures.
Can I use this 20TB drive in a desktop PC?
Yes! Any modern desktop PC with a 64-bit operating system (Windows 10/11) and GPT partition table supports full 20TB capacity via standard SATA.
How fast does it read and write compared to typical HDDs?
With 7200 RPM spindle speed and dense 20TB platters, it delivers up to 285 MB/s sustained transfer rates—over twice the speed of standard 5400 RPM desktop hard drives.
Is a SATA cable included?
This is an OEM bare drive product; SATA cables are typically provided with your motherboard or PC power supply.
