HUS723030ALS640 Présentation
A 3.5-inch enterprise HDD is a rotational magnetic storage device built around stacked aluminum platters, a high-speed spindle motor, and a multi-head actuator that delivers sequential and random access on a SATA or SAS transport. Within the broader storage taxonomy, the HUS723030ALS640 sits in the capacity-optimized segment of enterprise HDDs, below 10K/15K RPM performance HDDs and well below SSDs on the IOPS axis, but ahead of nearline-SATA drives on the interface reliability and dual-port fault-tolerance axis because SAS supports full-duplex dual-port operation. It is the workhorse building block of the Ultrastar 7K3000 family, and the suffix "A L S 6 4" decodes as Ultrastar-generation / large-form-factor / 512n sector / SAS 6 Gb/s / 64 MB cache.
Key specifications include sustained sequential read throughput of approximately 184 MB/s, sustained sequential write of roughly 200 MB/s, an average seek time near 8.2 ms, dual-port SAS connectivity, and a 2.0 million hour MTBF rating backed by a 5-year limited warranty. The drive also provides Rotational Vibration (RV) sensor technology for use in dense multi-drive chassis, Power Choice power management to reduce idle watts, and TLER / ERC (time-limited error recovery) to behave predictably inside RAID rebuilds.
Architecturally, the HUS723030ALS640 uses a 6 Gb/s SAS PHY with an 8B/10B encoded serial transport, a 64 MB DRAM read/write cache, and on-the-fly ECC across the recording channel. Its 5-platter, 10-head mechanical design delivers the 3 TB raw capacity, while its rotational speed and cache tuning target sequential workloads over random-IO micro-transactions.
Typical applications include enterprise backup targets, secondary storage tiers in software-defined storage, cold-data archival within hyperscale datacenters, surveillance/NVR bulk storage with sustained write streams, and capacity-tier nodes in scale-out object storage clusters. The 3 TB capacity point is also widely deployed as a Dell PowerEdge / Compellent FRU and as an Oracle / Sun / Cisco spare.
When designing systems around this drive, ensure the HBA or RAID controller supports 512n sector emulation (older controllers may default to 512e-only mode). Validate TLER behaviour matches the rest of the array to avoid spurious RAID dropouts, and provision airflow of at least 5 CFM per drive in dense enclosures to keep the ambient below 35 degrees Celsius.

Applications typiques
HUS723030ALS640 convient pour 6 applications: Enterprise RAID-6 Capacity Tier, Dell Compellent / PowerEdge Spare, Surveillance / NVR Bulk Storage, Cold Data Archival in Object Storage, Secondary Backup Target, Software-Defined Storage Capacity Node.
Enterprise RAID-6 Capacity Tier
The HGST HUS723030ALS640 anchors RAID-6 or RAID-10 capacity tiers in mid-range enterprise arrays where bulk storage cost per TB matters more than raw IOPS. Its 512n sector format, 64 MB cache, and 7,200 RPM spindle tolerate sustained sequential reads at up to ~184 MB/s and writes at ~200 MB/s, which matches nightly backup windows, software-defined storage pools, and replicated warm-data tiers. The TLER (Time-Limited Error Recovery) default of 7 seconds keeps a degraded array from cascading into multiple spurious drive drops during parity rebuilds, a real failure mode in production RAID-6 rebuilds. Each drive delivers 2.0 million hour MTBF and 0.44 percent AFR per HGST datasheet, supporting 24x7 operation without overheating the warranty budget of the array. Recommended companions: a SAS HBA or RAID controller with TLER matching, plus the chassis backplane wiring of the same drive family. Drop-in alternatives from the same family extend density without firmware changes.
Recommandé
Dell Compellent / PowerEdge Spare
The HUS723030ALS640-CL variant ships as a Dell-branded spare for Compellent SC-series and selected PowerEdge servers, and procurement teams routinely replace failed drives with this exact part. The drive carries Dell firmware, Dell warranty terms, and Dell kit tags, but the mechanics, MTBF, and 7200 RPM platform are identical to the standard HGST Ultrastar 7K3000. Using it as a hot spare preserves the array's TLER profile and prevents the firmware-mismatch alerts that sometimes occur when mixing OEM drives with non-OEM spares. Procurement teams should match part numbers exactly (HUS723030ALS640-CL for Compellent, the bare HUS723030ALS640 for Dell-branded PowerEdge) to keep management software happy.
Recommandé
Surveillance / NVR Bulk Storage
The HUS723030ALS640 works well in mid-size Network Video Recorder (NVR) deployments where 3 TB per drive and 7200 RPM bring enough throughput for 30+ concurrent 1080p camera streams at moderate bitrates. Surveillance workloads are bursty sequential writes during motion, and the 64 MB cache plus write-back firmware absorb these bursts without frame drops. The drive's RV sensor keeps it stable in multi-drive chassis (typical 16- or 24-bay NVR enclosures), and the 0.44 percent AFR is acceptable when RAID-6 or RAID-50 protects the array. Per the HGST datasheet, ambient operating temperature should remain below 60 degrees Celsius, so dense NVR chassis benefit from a 5 CFM per drive airflow specification.
Recommandé
Cold Data Archival in Object Storage
The HUS723030ALS640 is a reasonable node drive for cold-data tiers in object storage platforms like OpenStack Swift, Ceph cold pools, or S3-compatible cold-tier gateways. At USD 15.68 per TB (used market, 2026-10-14) it competes favorably with nearline SATA drives when SAS-grade reliability is desired. Object storage workloads are dominated by sequential reads and large append-only writes, exactly the pattern the 7K3000's 200 MB/s sustained write and TLER behaviour prefer. Pair the drives in 12+1 or 24+2 erasure-coding pools to absorb up to two simultaneous drive failures without data loss while still hitting capacity-density targets in dense Rackscale configurations.
Recommandé
Secondary Backup Target
Small and mid-size enterprise backup targets running Veeam, Commvault, or NetBackup benefit from the HUS723030ALS640's combination of 3 TB capacity, 7200 RPM performance, and 2.0 million hour MTBF. Backup windows are dominated by sequential write streams rather than random IO, and the 7K3000's 64 MB write-back cache helps large-block writes flush efficiently between tape-like job cycles. The TLER setting keeps the drive in lockstep with mixed-brand peers inside a virtualized backup target, avoiding the spurious dropouts that consumer drives cause during nightly de-duplication passes.
Recommandé
Software-Defined Storage Capacity Node
The HUS723030ALS640 fits the capacity node role in software-defined storage (SDS) platforms such as vSAN capacity tier, Storage Spaces Direct, or SUSE Enterprise Storage, where 3 TB per drive at 7200 RPM keeps capital expenditure low while SAS 6 Gb/s dual-port provides the multipath enterprise connectivity these platforms recommend. At 0.44 percent AFR the drive meets the typical 24x7 SLA for nearline workloads and tolerates SDS erasure coding windows of 12+2 without inflating rebuild times. The 5-platter design has been validated across multiple SDS reference architectures, and the 512n sector size simplifies mixed deployments with legacy operating systems.

Notes de conception
The HUS723030ALS640 ships with TLER (Time-Limited Error Recovery) enabled by default to a 7-second window. Verify the same TLER setting is active on every drive in a mixed-vendor RAID array; a single consumer-grade drive that lacks TLER (and therefore retries indefinitely on a bad sector) will cause the entire RAID set to mark the drive as failed mid-rebuild. Per HGST's datasheet, TLER must match across the array for predictable rebuild behaviour.
Specified for 5C to 60C ambient operation. In dense 16- or 24-bay enclosures, airflow of at least 5 CFM per drive bay is recommended to keep the ambient below 50C. Estimation: a fully populated chassis with 12 BTU/hour per drive (idling at 8W each) plus two PSUs can easily push ambient over the 60C limit if passive airflow is the only path. Active cooling with redundant fans is strongly recommended for RAID arrays at full population.
The HUS723030ALS640 uses the SFF-8482 SAS connector on a single PCB that combines the SAS data transceivers, the 64 MB DRAM cache, and the proprietary HGST servo controller. Field failures are most commonly attributed to PCB burn damage (per hddfaqs.com data) rather than media wear. When matching a replacement PCB, capture the Main Controller IC Number and the White Label / ROM contents exactly - firmware is married to the drive's adaptive parameters and re-flashing the ROM from a donor drive rarely restores full performance.
The SAS 6 Gb/s interface multiplexes two discrete ports (primary plus secondary) within the same SFF-8482 connector. When deploying dual-port to two separate HBAs (A and B), ensure the backplane routes each pair to a separate connector segment. Mixing ports on the same HBA defeats redundancy and turns dual-port into an extra-cost single-port. Per the SAS SFF-8482 specification the secondary port's pins (P25-P29) must be actively terminated if unused, otherwise signal reflection can degrade primary-port performance under heavy load.
