Enterprise 2.5-inch SAS drive

The Seagate ST1000NX0323 is a 1TB enterprise hard drive with a 2.5-inch form factor, 15mm height and a SAS 12Gb/s interface. It spins at 7200 RPM and carries a 128MB cache for sustained throughput in nearline storage arrays. The drive is built for 24x7 operation in space-constrained data centres.

Suits high-density enterprise arrays.

This unit fits servers and storage enclosures that accept 15mm 2.5-inch SAS drives and need low power per terabyte. Buyers upgrading consumer laptops or slim workstations that only take 7mm SATA drives cannot use this model.

SAS 12Gb/s interface decides fit

The drive connects through a 12Gb/s SAS port, so the host backplane or controller must support that standard. A system with only SATA 6Gb/s connectors will not recognise the drive.

Spørgsmål om denne vare

What does the SAS 12Gb/s interface cap in real-world throughput?

The SAS 12Gb/s link tops out at 12 Gbit/s; sustained sequential transfers reach 18% higher than the previous generation, while the 128 MB cache absorbs bursts before the 7200 RPM platters become the bottleneck.

What physical clearance does the 15 mm z-height drive need?

The drive measures 100.46 mm long, 70.10 mm wide and 15 mm tall, so the host bay must accommodate a 15 mm 2.5-inch form factor; many slim laptops only accept 7 mm models.

How is the drive installed, and which step is often missed?

Connect the SAS data and power connectors, secure the drive with four M3 screws, then configure the RAID controller or HBA for 4Kn sector mode; skipping the 4Kn setting causes the drive to report zero capacity.
