Enterprise 3.84 TB SATA SSD

The Seagate Nytro 1551 is a 2.5-inch enterprise solid-state drive with 3.84 TB capacity and a SATA III interface. It uses 3D TLC memory and targets servers or storage arrays that need high-capacity read-intensive storage. The drive delivers up to 560 MBps sequential read and 535 MBps sequential write speeds.

Compatibility check

Verify that your system provides a 2.5-inch drive bay and a SATA 6 Gb/s port for full performance. Confirm the operating environment stays within 0 °C to 70 °C and that the chassis can handle the drive's physical dimensions. Ensure the workload matches the drive's endurance rating of 3 DWPD before deployment.

Thermals and power

Idle power draw is 1.2 W and active power reaches 3.5 W, keeping heat output low in typical server workloads. The drive operates reliably from 0 °C up to 70 °C without active cooling requirements. With no moving parts, acoustic noise is effectively zero during normal operation.

Questions about this item

What is included with the Seagate Nytro 1551 XA3840ME10063 and do I need a separate SATA cable?

The drive ships as a bare 2.5-inch SATA SSD. A SATA data cable and a SATA power connector from your server or storage array are required separately for installation.

Why choose the 3.84TB Nytro 1551 over a smaller capacity in the same series?

The 3.84TB model delivers up to 560 MBps sequential read and 85,000 random read IOPS with 3.5W active power, giving the highest throughput and IOPS per watt in the lineup for read-heavy enterprise workloads.

How does the 560 MBps sequential read figure translate in a real server?

In a SATA 6Gb/s backplane the drive saturates the bus at up to 560 MBps, so large-block reads such as log ingestion or backup streaming run at near wire speed with 175 µs average read latency.
