Lenovo 4XB7A93480 ThinkSystem 2.5in U.2 CD8P 1.92TB Read Intensive NVMe PCIe 5.0 x4 SSD

Overview

The Lenovo 4XB7A93480 is a 1.92TB 2.5-inch U.2 NVMe solid-state drive built for ThinkSystem servers running read-heavy enterprise workloads — analytics databases, video surveillance storage tiers, AI inference caches, and high-throughput object repositories where sequential read bandwidth and low read latency are the primary constraints. Riding enterprise NVMe SSDs' newest interface tier, it uses PCIe 5.0 x4 to deliver bandwidth that prior-generation PCIe 4.0 drives simply cannot match, making it a meaningful step up in server storage performance within the Lenovo ThinkSystem server line.

With 1,600,000 random read IOPS and sequential read throughput of 12,000 MB/s measured via ATTO, the 4XB7A93480 is positioned at the high end of what 2.5-inch U.2 form factor drives can deliver today. TLC NAND keeps capacity-per-dollar practical at 1.92TB while hardware encryption via TCG Opal 2.0 means you're not trading security for performance.

Key Features

• PCIe 5.0 x4 Interface — 12,000 MB/s Sequential Read: PCIe 5.0 doubles the per-lane bandwidth of PCIe 4.0. At x4, this drive hits 12,000 MB/s sequential reads via ATTO testing — the difference between a storage bottleneck and a compute bottleneck on multi-stream video ingest or large-dataset analytics jobs. If your ThinkSystem server has PCIe 5.0 U.2 bays, you are leaving measurable throughput on the table with a gen-4 drive here.
• 1,600,000 Random Read IOPS (4KB): At 4KB block random reads — the pattern that dominates surveillance indexing, transaction logs, and AI feature-vector lookups — this drive delivers 1.6 million IOPS. That is roughly four times what a mid-range PCIe 4.0 NVMe can sustain, and it means the storage tier stops being the limiter in concurrent-query workloads.
• 150,000 Random Write IOPS (4KB): Write IOPS are rated at 150,000 — a ratio of roughly 10:1 read-to-write, which directly reflects the Read Intensive (RI) targeting. This is not the drive for mixed or write-heavy workloads. For read-dominated environments — replicated object stores, read replicas, content delivery caches — the write budget is more than adequate.
• 69 µs Read Latency / 10 µs Write Latency: Sub-100 µs read response keeps latency-sensitive applications (real-time analytics, motion-event retrieval from video archives) from stalling on storage. The 10 µs write latency is exceptionally low for TLC NAND and benefits write-commit operations even in predominantly read workloads.
• 3,500 MB/s Sequential Write: While read throughput gets the headline, 3,500 MB/s sequential write is fast enough to handle bulk ingest events — initial video archive writes, database backup streaming, large-file transfers — without creating a queue backlog that degrades concurrent read performance.
• TLC NAND — 1.92TB Capacity: Triple-Level Cell NAND delivers the right cost-per-gigabyte for read-intensive use cases where endurance requirements are lower than write-intensive workloads. At 1.92TB in a 2.5-inch U.2 form factor, it slots into standard hot-swap bays without requiring additional drive caddies or adapters beyond what Lenovo ThinkSystem platforms already ship with.
• Hot-Swap Support: Hot-swap capability means this drive can be replaced under power in a running server — critical for deployments that cannot tolerate downtime for drive servicing. Plan your RAID or storage pool configuration accordingly so a single-drive pull does not interrupt availability.
• TCG Opal 2.0 Hardware Encryption: Encryption is performed in the drive controller, not the host CPU, so there is zero performance penalty for enabling data-at-rest protection. TCG Opal 2.0 compliance integrates with enterprise key management systems and satisfies data security requirements for regulated environments without requiring software encryption layers that consume server cycles.
• S.M.A.R.T. Monitoring: S.M.A.R.T. support enables the host system and storage management software to track drive health metrics — wear indicators, error counts, temperature — proactively. In ThinkSystem environments this feeds into Lenovo XClarity management for predictive failure alerting before a drive actually fails in production.

Integration and Compatibility

The 4XB7A93480 is a ThinkSystem-qualified option designed for Lenovo server platforms that provide 2.5-inch U.2 NVMe hot-swap bays with PCIe 5.0 host connections. Verify your specific ThinkSystem model's hardware compatibility list (HCL) before ordering — PCIe 5.0 U.2 backplane support is not universal across the ThinkSystem line, and installing a PCIe 5.0 drive into a PCIe 4.0 backplane will run at PCIe 4.0 speeds, eliminating the bandwidth advantage. Review server storage options or consult the Lenovo ServerProven compatibility matrix for your chassis model.

For surveillance-focused deployments, this drive is well-suited as the primary storage tier in a ThinkSystem-based NVR or video analytics server — high sequential read throughput handles simultaneous multi-stream video playback, while low random read latency supports motion-search and forensic retrieval. Pair it with a network video recorder or server-based VMS platform that can fully exploit NVMe-native I/O queuing. For storage capacity planning across multi-camera deployments, a storage retention planning guide helps right-size your drive count against retention requirements.

The U.2 (SFF-8639) connector is standard for enterprise 2.5-inch NVMe; confirm your server backplane uses this interface rather than M.2 or EDSFF (E1.S/E3.S) form factors, which are incompatible. A storage category overview can help identify complementary drives if you need a mix of capacity and performance tiers in the same chassis.

Frequently Asked Questions

Q: What interface does the Lenovo 4XB7A93480 use?

A: The 4XB7A93480 uses a PCIe 5.0 x4 NVMe interface in the 2.5-inch U.2 (SFF-8639) form factor. It requires a ThinkSystem server with a compatible PCIe 5.0 U.2 backplane to operate at full rated speeds of 12,000 MB/s sequential read.

Q: Is this drive suitable for write-intensive workloads like databases with high write throughput?

A: No — the 4XB7A93480 is rated and binned as a Read Intensive (RI) drive, with 1,600,000 read IOPS versus 150,000 write IOPS. It is the correct choice for read-dominated workloads (analytics, video playback, caching, read replicas). For balanced or write-heavy workloads, a Mixed Use (MU) or Write Intensive (WI) variant in the ThinkSystem CD8 family would be more appropriate.

Q: Does this SSD support hardware encryption?

A: Yes. The drive includes hardware-based encryption compliant with TCG Opal 2.0. Encryption is performed in the drive controller with no CPU overhead on the host system. This supports integration with enterprise key management platforms for data-at-rest security.

Q: Can this drive be replaced without powering down the server?

A: Yes — the 4XB7A93480 supports hot-swap, meaning it can be removed and replaced while the server remains powered on, provided the host storage controller and configuration (RAID or erasure coding pool) support online drive replacement. Always verify your controller and OS configuration before hot-pulling a drive in production.

Q: What is the NAND type used in this drive?

A: This drive uses TLC (Triple-Level Cell) NAND. TLC provides a favorable capacity-per-dollar ratio appropriate for read-intensive workloads where write endurance requirements are lower than MLC or SLC alternatives.

Karl Wilson

The 4XB7A93480 stands out on one number for me: 12,000 MB/s sequential read over PCIe 5.0 x4. That is the headline spec that changes the conversation when you are sizing storage for a high-density video analytics node or a surveillance VMS running concurrent forensic searches across dozens of high-resolution camera streams. Gen-5 bandwidth in a U.2 form factor means you are no longer bottlenecked at the storage interface when the CPU and GPU are both ready to process data.

Technical Highlights:

• PCIe 5.0 x4 Sequential Read at 12,000 MB/s: Doubles the effective read bandwidth of a comparable PCIe 4.0 U.2 drive — relevant wherever sustained multi-stream read throughput matters, including parallel video decode or large-model weight loads in inference servers.
• 1,600,000 Random Read IOPS at 4KB: The 10:1 read-to-write IOPS ratio (1.6M read vs. 150K write) tells you exactly what this bin is optimized for. In surveillance applications, random read dominates during event retrieval and forensic review; this drive does not throttle under that pattern.
• TCG Opal 2.0 Hardware Encryption: Controller-side encryption with zero CPU tax. In regulated environments — healthcare, finance, government video surveillance infrastructure — this removes the compliance objection without adding a software encryption layer that consumes server resources.

Deployment Considerations:

• Verify PCIe 5.0 U.2 backplane support on your specific ThinkSystem chassis before ordering. A PCIe 5.0 drive in a PCIe 4.0 backplane trains down to gen-4 speeds — you pay the gen-5 premium and capture none of the bandwidth gain. Check the Lenovo ServerProven HCL for your exact chassis model.
• The RI workload classification means write endurance is lower than a Mixed Use drive in the same family. Monitor S.M.A.R.T. wear indicators via Lenovo XClarity in production — in workloads that unexpectedly shift write-heavy (log accumulation, backup target reuse), you will consume drive life faster than the RI rating assumes.

For a ThinkSystem-based video analytics server or high-density NVR platform handling 50+ simultaneous 4K streams with real-time forensic search, the 4XB7A93480 is the correct storage tier choice — provided your chassis supports PCIe 5.0 U.2 and your workload profile stays read-dominant.
