Enterprise 24x7 storage drive

The Seagate Constellation ES.3 ST2000NM0023 is a 2TB 3.5-inch enterprise hard drive built for 24x7 operation. It spins at 7200 RPM with a 128MB cache and connects through a SAS 6Gb/s interface. The bare drive measures 147.00mm long, 101.85mm wide and 26.10mm high.

Best for RAID arrays and servers

This drive suits administrators who need predictable performance in multi-drive SAS environments with enhanced error correction and end-to-end data integrity. Buyers who want a desktop boot drive or external storage without a SAS controller should look at something else.

SAS 6Gb/s interface requirement

The drive uses a SAS 6Gb/s interface that requires a compatible host bus adapter or RAID controller for operation. It will not connect to standard desktop motherboard ports.

商品問答

Should I pick the 2TB capacity or a larger SAS drive for my storage array?

The ST2000NM0023 provides 2TB of enterprise-grade capacity; choose it if your array design matches this density and you need 7200 RPM performance with 128MB cache.

What does 7200 RPM with 128MB cache deliver in a live server?

It gives predictable 7200-RPM throughput and low 4.16ms average latency for 24x7 bulk data workloads in SAS environments.

The drive uses SAS 6Gb/s — what real-world throughput ceiling does that impose?

The SAS 6Gb/s interface caps the maximum transfer rate at 6Gb/s, so sustained reads and writes cannot exceed that link speed.
