Lenovo 4XB7B03894 24TB 7.2K 3.5-Inch HDD for ThinkSystem DE Series 4U60
Overview
The Lenovo 4XB7B03894 is a 24TB, 7,200 RPM 3.5-inch hard disk drive purpose-built for Lenovo ThinkSystem DE Series storage enclosures, specifically the 4U60 platform. At 24TB per spindle, this drive is designed for high-density bulk storage workloads — think surveillance video retention, archive tiers, backup targets, and large-scale unstructured data repositories where cost-per-terabyte matters more than raw IOPS. If you are expanding an existing DE Series 4U60 enclosure or populating a new one, this is the factory-matched drive Lenovo validates for that platform.
Weighing in at 5.00 lb, the drive ships at standard 3.5-inch large-form-factor dimensions, compatible with the high-density 4U60 shelf configuration. Sourced factory-new with no grey-market provenance, the 4XB7B03894 ensures firmware compatibility and enclosure interoperability that aftermarket alternatives cannot guarantee.
Key Features
- 24TB raw capacity per drive: Populating a 4U60 enclosure with high-density spindles like this one means maximizing usable storage without adding enclosures or rack space — directly relevant when you are managing 30-, 60-, or 90-day video retention across dozens of camera feeds.
- 7,200 RPM rotational speed: The 7.2K spindle speed delivers a workable balance between sequential throughput and power draw for near-line storage — appropriate for surveillance write workloads and archive reads, where burst IOPS requirements are moderate but sustained throughput matters.
- 3.5-inch large-form-factor: Matches the physical bay specification of the ThinkSystem DE Series 4U60, which is engineered around 3.5-inch drives for maximum per-shelf capacity density. Do not attempt to install this in 2.5-inch SFF bays or non-DE enclosures — physical and logical compatibility is enclosure-specific.
- ThinkSystem DE Series platform integration: Lenovo qualifies drives on a per-platform basis. Using the validated 4XB7B03894 in a DE Series 4U60 ensures firmware interoperability, predictive failure monitoring via the enclosure's management stack, and no compatibility flags in Lenovo XClarity or the DE storage management interface.
- Near-line HDD class: Near-line drives at this capacity tier are the correct choice for sequential-dominant workloads. For random-access-heavy applications like transactional databases, a different storage class would be appropriate — this drive is optimized for the write-heavy, read-sequential pattern of video surveillance and backup.
- Factory-new condition: Supplied as a genuine, factory-new unit, not refurbished or pulled. This matters for drive warranty coverage and for maintaining enclosure support agreements tied to Lenovo-qualified components.
Integration and Compatibility
The 4XB7B03894 is validated for the Lenovo ThinkSystem DE Series 4U60 enclosure. Before ordering, confirm your enclosure model and current firmware revision against Lenovo's compatibility matrix — DE Series enclosures have platform-specific drive qualification lists, and mixing unvalidated drives can void enclosure support. This drive is not a universal NAS or server HDD; it is a platform-specific option for the DE Series family.
For surveillance deployments, pair this drive with a compatible network video recorder or storage server feeding the DE Series enclosure over the appropriate fabric. High-density IP camera deployments generating continuous 24/7 streams will benefit most from maximizing per-enclosure capacity with 24TB spindles, reducing the number of shelves needed to meet retention targets. Consider your PoE switch and network architecture as part of the overall storage sizing exercise — camera stream bitrates directly determine how quickly this capacity fills.
If you are evaluating total storage architecture, review a storage and retention planning guide to size spindle count and enclosure density against your actual camera count, resolution, and retention policy before committing to a drive quantity.
Frequently Asked Questions
Q: Is the Lenovo 4XB7B03894 compatible with enclosures other than the ThinkSystem DE Series 4U60?
A: The 4XB7B03894 is validated specifically for the Lenovo ThinkSystem DE Series 4U60 platform. Lenovo qualifies drives on a per-enclosure basis, so compatibility with other enclosures — including third-party or non-DE Lenovo systems — is not confirmed by the available evidence. Verify against Lenovo's official compatibility matrix for your enclosure before ordering.
Q: Is the 4XB7B03894 suitable for 24/7 continuous surveillance recording workloads?
A: The 7,200 RPM near-line HDD class is well-suited for the sequential write patterns of continuous surveillance recording. Near-line drives at this capacity tier are designed for write-heavy, read-sequential workloads typical of video surveillance and archive applications rather than random-access transactional use.
Q: What is the physical weight of the 4XB7B03894?
A: The drive weighs 5.00 lb. Factor this into enclosure weight planning when fully populating a 4U60 shelf, as total loaded enclosure weight affects rack capacity and floor loading requirements.
Q: Does using a non-Lenovo-validated drive in the DE Series 4U60 affect support?
A: Lenovo qualifies specific drives for each DE Series enclosure. Using drives outside the validated list can result in compatibility flags, unsupported configurations, and potential impact on enclosure support agreements. The 4XB7B03894 is the factory-matched option for this platform.
Q: Is the 4XB7B03894 a new drive or refurbished?
A: The 4XB7B03894 is supplied factory-new — not refurbished, not pulled from another system. This matters for maintaining manufacturer warranty coverage and for enclosure support eligibility tied to genuine Lenovo-qualified components.
The 4XB7B03894 is a straightforward platform-matched storage decision: if you are running a Lenovo ThinkSystem DE Series 4U60 enclosure and need to maximize capacity per shelf, this is the validated 24TB 3.5-inch spindle Lenovo qualifies for that platform. At 5.00 lb per drive, weight budget is something to calculate before you commit to a full shelf population — that adds up fast in a high-density 4U60 configuration.
Technical Highlights:
- 24TB per spindle: Highest-density option for the 4U60 bay count — fewer shelves needed to hit a given retention target, which matters in rack-constrained surveillance data centers.
- 7,200 RPM near-line class: Delivers sequential throughput appropriate for surveillance ingest and archive read without the power and cost overhead of enterprise SAS 10K/15K drives — the right engineering tradeoff for write-dominant, read-sequential video workloads.
- Platform-validated for DE Series: Lenovo's per-enclosure qualification process means the 4XB7B03894 is recognized by the enclosure firmware, monitored by predictive failure analytics, and won't generate compatibility alerts in Lenovo XClarity.
Deployment Considerations:
- Calculate total loaded enclosure weight before ordering quantity — a fully populated 4U60 with 3.5-inch drives at 5.00 lb each is a significant rack load; verify your rack's weight rating and floor loading spec in advance.
- Do not substitute this drive into non-DE Series enclosures or assume cross-platform compatibility — Lenovo's qualification is enclosure-specific, and mixing unvalidated drives risks support implications and potential firmware incompatibility.
Best fit for surveillance deployments that have already standardized on the Lenovo ThinkSystem DE Series 4U60 platform and need to maximize raw capacity per enclosure for long-retention multi-camera recording — particularly relevant in enterprise physical security infrastructure where the storage fabric is Lenovo-native and support consistency is a priority.
