Enterprise Nearline Storage
The Seagate Exos 7E2000 ST2000NX0343 is a 2TB SAS 12Gb/s hard drive built for enterprise storage arrays. Its 2.5-inch, 15mm z-height form factor fits high-density servers and space-constrained data centres. The 512e advanced format and 128MB cache support demanding workloads requiring consistent data integrity and scalability.
Thermals and Power Efficiency
Designed for 24x7 operation, the drive targets low power consumption and low weight to maximise storage efficiency in dense racks. PowerChoice technology allows host-controlled power management during idle periods. The 7200 RPM spindle speed and 4.16ms average latency deliver steady performance without exceeding typical enterprise thermal envelopes.
Security and Reliability Features
Seagate Secure provides hardware-based encryption for data-at-rest protection. RAID Rebuild accelerates array recovery times compared to standard rebuilds. The drive carries a 2M hour MTBF rating and 0.44% AFR specification for enterprise-grade reliability. SAS interface ensures dual-port connectivity for path redundancy in mission-critical deployments.

이 상품에 대한 질문
How do I install the ST2000NX0343 in a 2.5-inch SAS bay and what step is often missed?
Slide the 15mm-high drive into the bay, secure it with the correct screws, and attach the SAS 12Gb/s data and power connectors; the step often missed is confirming the controller supports 512e advanced format before first use.
What maintenance or replacement will this enterprise HDD need over its service life?
Rated for 2M hours MTBF and 0.44% AFR, it is designed for 24x7 operation with no scheduled maintenance; replacement is driven by SMART alerts or capacity upgrades rather than a fixed interval.
What limit appears first when the drive runs sustained workloads at 7200 RPM?
The 12Gb/s SAS interface bandwidth and 128MB cache set the sustained throughput ceiling; thermal throttling in a 15mm z-height enclosure can also reduce performance before the 2TB capacity fills.
