Capacity and interface

The Seagate Exos X20 ST20000NM007D is a 20TB 3.5-inch internal hard drive with a SATA 6.0Gb/s interface and 7200 RPM spindle speed. It uses conventional magnetic recording and a 256MB cache to deliver high sequential throughput for enterprise storage arrays and hyperscale applications. The 512e/4Kn format supports modern operating systems and legacy controllers alike.

System compatibility

Verify that your host has a free 3.5-inch drive bay and a SATA 6.0Gb/s port capable of 600 MB/s transfer rates. The drive measures 147mm long, 101.85mm wide and 26.10mm high, so confirm physical clearance in compact chassis. A SATA power connector is required; the unit is hot-pluggable for supported backplanes.

Upgrade path

This model replaces lower-capacity 3.5-inch enterprise drives where rack density and cost per terabyte are primary concerns. The jump is worthwhile when workloads demand 2.5M-hour MTBF reliability, sustained random performance of 168000 read and 550000 write IOPS, and the lowest total cost of ownership for massive scale-out deployments.

Kysymyksiä tästä tuotteesta

Does the Seagate Exos X20 ST20000NM007D include mounting screws or a SATA cable, or must they be purchased separately?

The drive is supplied as a bare 3.5" unit; mounting screws and a SATA data cable are not included and must be sourced separately.

Should I choose the 512e or 4Kn disk format for a modern server running a recent Linux kernel?

The drive supports both 512e and 4Kn; 4Kn is preferred on modern Linux kernels for full 4 KB sector efficiency, while 512e maintains compatibility with older systems.

What sustained throughput can I expect from the 7200 RPM SATA 6.0Gb/s interface once the drive is installed in a RAID array?

The SATA 6.0Gb/s link caps at 600 MB/s; real-world sustained transfer rates will be lower and depend on workload, but the interface itself does not exceed 600 MB/s.
