Lenovo 4XB7A95047 ThinkSystem 2.5" U.2 P5336 7.68TB Read Intensive NVMe PCIe 4.0 x4 Hot-Swap SSD
Overview
The Lenovo 4XB7A95047 is a 7.68TB, 2.5-inch U.2 NVMe solid-state drive from the ThinkSystem P5336 Read Intensive family, designed for high-density storage workloads inside Lenovo ThinkSystem server platforms. Built on a PCIe 4.0 x4 interface, this drive targets environments where read throughput and storage density matter — surveillance video repositories, large log archives, and read-heavy database tiers where sequential read performance is the constraint, not write endurance. The hot-swap (HS) carrier means a failed drive can be replaced without powering down the host system, which matters in any always-on deployment.
Key Features
- 7.68TB U.2 NVMe capacity: High-density storage in a 2.5-inch hot-swap bay reduces the number of drive slots consumed per usable terabyte — a practical consideration when planning multi-camera video retention across weeks or months of footage.
- PCIe 4.0 x4 interface: PCIe Gen 4 doubles the theoretical bandwidth ceiling of Gen 3, giving the host CPU faster access to the full 7.68TB pool — meaningful for workloads that stream large sequential reads continuously, such as video export or analytics pipeline ingestion.
- Read Intensive classification: The P5336 is tuned for workloads with a high read-to-write ratio — video surveillance archives and content repositories fit this profile well. For write-heavy workloads (database transaction logs, frequent overwrites), a Mixed Use or Write Intensive class drive is the correct choice instead.
- Hot-swap design: The HS carrier allows live replacement in compatible ThinkSystem bays without a maintenance window, keeping uptime intact for storage arrays running continuous recording or 24/7 operational workloads.
- ThinkSystem platform integration: As part of the Lenovo ThinkSystem storage accessory line, the 4XB7A95047 is validated for use in compatible ThinkSystem servers, ensuring firmware compatibility and platform-level support.
- Manufactured in Mexico (MX): Country of origin is documented — relevant for procurement teams tracking supply-chain sourcing requirements or TAA-related purchasing guidelines. Verify TAA compliance independently for your specific contract vehicle.
Integration and Compatibility
The 4XB7A95047 uses the U.2 (SFF-8639) connector and PCIe 4.0 x4 signaling — confirm your ThinkSystem server model supports PCIe Gen 4 U.2 bays before ordering. Pairing this drive with a high-throughput network fabric ensures the storage tier is not the bottleneck in a video management or data pipeline architecture. For platform-specific compatibility matrices, consult the Lenovo ServerProven database using the host server's machine type.
Frequently Asked Questions
Q: What workload class is the Lenovo 4XB7A95047 designed for?
A: The P5336 carries a Read Intensive rating, meaning it is optimized for workloads where reads significantly outnumber writes — video surveillance archives, log repositories, and read-heavy analytics are well-matched use cases. Write-heavy workloads should use a Mixed Use or Write Intensive class drive.
Q: What interface does the 4XB7A95047 use?
A: It uses a PCIe 4.0 x4 NVMe interface with a U.2 (SFF-8639) connector. The host server must support PCIe Gen 4 U.2 bays — verify compatibility via Lenovo's ServerProven tool for your specific machine type.
Q: Is this drive hot-swappable?
A: Yes. The HS designation indicates it ships in a hot-swap carrier, allowing replacement in a live ThinkSystem bay without powering down the server, provided the bay and backplane support hot-swap operation.
Q: What is the country of origin for the 4XB7A95047?
A: The documented country of origin is Mexico (MX). For TAA compliance verification under specific government contract vehicles, confirm with your contracting officer using the official Lenovo product compliance documentation.
Q: Can this drive be used in non-Lenovo servers?
A: The drive uses a standard U.2 PCIe 4.0 x4 interface that is physically compatible with other U.2 platforms, but Lenovo validates and supports the 4XB7A95047 specifically within ThinkSystem servers. Use in third-party platforms may void support agreements and is not verified by available evidence.
The 4XB7A95047 is one of those drives that makes sense specifically when your ThinkSystem platform already runs PCIe Gen 4 backplanes and you need to maximize storage density per bay. At 7.68TB in a 2.5-inch U.2 hot-swap form factor, you are getting a meaningful capacity per slot — the Read Intensive classification signals Lenovo tuned the endurance budget toward read-dominant access patterns, not balanced or write-heavy ones.
Technical Highlights:
- 7.68TB U.2 form factor: Fitting this capacity into a standard 2.5-inch hot-swap bay is the key density advantage — fewer bays consumed per terabyte compared to smaller NVMe options, which directly reduces chassis slot pressure in dense deployments.
- PCIe 4.0 x4 interface: Gen 4 doubles the lane bandwidth versus Gen 3 — the practical benefit is higher sustainable throughput when the workload streams large sequential reads continuously, such as pulling archived video segments or feeding an analytics pipeline.
- Hot-swap carrier: Live replacement without a maintenance window is the operational differentiator here. In a 24/7 environment — continuous recording infrastructure, always-on storage arrays — this eliminates the scheduled downtime a non-hot-swap drive would require.
Deployment Considerations:
- Verify your ThinkSystem server explicitly supports PCIe Gen 4 U.2 bays via Lenovo ServerProven before ordering — PCIe Gen 3 backplanes will physically accept the U.2 connector but will not run the drive at Gen 4 speeds.
- Read Intensive drives carry lower write endurance ratings than Mixed Use or Write Intensive variants — if your workload involves frequent overwrites or sustained write throughput (transaction logs, cache tiers), this is the wrong drive class regardless of capacity.
The 4XB7A95047 is a strong fit for ThinkSystem-based video archive servers and read-heavy storage tiers where density per bay and hot-swap serviceability are the primary design requirements — not for write-intensive or mixed transactional workloads.
