Verdict: The Solidigm D5-P5336 61.44TB is a specialized enterprise NVMe SSD for read-heavy storage where fitting more capacity into fewer drive bays is worth the price. Its PCIe 4.0 read performance and 65.2PB rated endurance are substantial, but its QLC NAND and 0.58 drive writes per day rating make it a poor default for write-heavy databases, scratch space, or consumer PCs. Buy it only after confirming the server supports its U.2 or E1.L form factor, power and cooling needs, and exact security SKU.
What the D5-P5336 61.44TB is—and is not
The D5-P5336 is a data-center NVMe SSD based on 192-layer QLC NAND. The 61.44TB model combines that high-capacity flash with a PCIe 4.0 x4 interface. It is designed for read-intensive, data-heavy systems—not as a general-purpose consumer SSD. It is not an M.2 module: the 61.44TB configurations documented by Solidigm are U.2 15mm and E1.L. The product family includes E3.S models at other capacities, but the original product brief does not identify 61.44TB as a standard E3.S configuration. Solidigm’s product brief lists family capacities from 7.68TB to 61.44TB, with availability varying by form factor.
“61.44TB” is the marketed decimal capacity. An operating system may show a lower figure because it reports capacity using binary units; usable space also falls with formatting, filesystem metadata, RAID or erasure-coding overhead, and any reserved capacity.

The trade-off is that QLC is generally less suited than enterprise TLC or SLC to sustained, write-heavy workloads. That does not make this drive inherently unreliable or unsuitable for enterprise use: firmware, power-loss protection and data-path protection are part of the product. It does mean that endurance, write patterns and latency under load matter more than the headline read speed.

Specifications at a glance
| Specification | 61.44TB model |
|---|---|
| Capacity and NAND | 61.44TB; 192-layer QLC |
| Interface | PCIe 4.0 x4; NVMe 1.4 |
| Documented form factors | U.2 15mm and E1.L 9.5mm |
| Maximum sequential read | Up to 7,000MB/s |
| Maximum sequential write | Up to 3,000MB/s |
| Endurance rating | 0.58 DWPD for five years; 65.2PB written (PBW) |
| Power | Up to 25W; under 5W idle |
| MTBF | 2 million hours |
| Power-off retention | 3 months at 40°C |
| Other listed features | OCP 2.0 support; FIPS 140-3 Level 2 on applicable SKUs |
These are manufacturer specifications, not application guarantees. In particular, “up to 3,000MB/s” is a maximum sequential-write figure, not a promise of sustained write throughput for every workload. The brief also lists an indirection unit of 16KB and UBER below one sector per 1017 bits read. Check the exact model and data sheet for the configuration you plan to order.
Performance: strong reads, much weaker random writes
StorageReview’s test results are summarized on a Solidigm-hosted page about StorageReview’s review. The figures below come from that summary, so they should not be confused with an independent review hosted by Solidigm or a current comparison against every competing drive. They show a clear pattern: high read throughput and strong read-oriented application results, alongside much lower random-write performance.
| Test | Reported result |
|---|---|
| 4K random read | Approximately 999K IOPS at 509.4µs |
| 4K random write | Approximately 106K IOPS at 4,823µs |
| 64K sequential read | 7.11GB/s; 114K IOPS |
| 64K sequential write | 2.5GB/s; 34K IOPS |
| 64K random read | 5.51GB/s; 88K IOPS |
| 64K random write | 2.1GB/s; 33K IOPS |
| SQL workload | 249K IOPS at 127.5µs |
| SQL 90/10 | 239K IOPS at 132.4µs |
| SQL 80/20 | 227K IOPS at 139.4µs |
The summary appears to print the 4K random-read result as “999 IOPS.” In the context of the reported benchmark, that is an apparent formatting or transcription error; the intended result is approximately 999K IOPS. The table uses that interpretation and flags the discrepancy rather than treating the printed figure as literal.
Rank #2
- Item dimensions: 5.5 inches
The results came from a Lenovo ThinkSystem SR635 with an AMD EPYC 7742, eight 64GB DDR4-3200 ECC memory modules, CentOS 7.7 1908 and VMware ESXi 6.7u3, using vdBench-based testing. The comparison set included Micron 6500 ION and Solidigm D5-P5316 drives. Those are enterprise-server results, not desktop benchmarks or a universal leaderboard. Queue depth, block size, preconditioning, firmware, overprovisioning, host CPU, PCIe topology, cooling and RAID configuration can all affect results.
The practical takeaway is not simply that the drive is “fast.” It is that its strengths align with read-heavy data lakes, content and media repositories, AI or machine-learning datasets that are read repeatedly, cloud and object-storage back ends, analytics, search indexes, and some VDI boot or login workloads. Whether a specific deployment sees similar performance depends on its server and workload. For sustained random writes, the reviewed results are a warning to benchmark the full system rather than relying on the maximum sequential-write specification.
What 0.58 DWPD means in practice
DWPD means drive writes per day. A 0.58 DWPD rating over five years means the rated workload permits writing approximately 58% of the drive’s rated capacity each day under the manufacturer’s endurance methodology. Solidigm lists 65.2PBW for the 61.44TB model over its five-year rating period. That is a large absolute write allowance, but it is not unlimited endurance or a blanket assurance for any workload.
Rank #3
- Interface type: PCI Express
- Drive system: Internal
- Height: 0.6
- Internal/external: Internal
- Hard Drive Capacity: 30.72 TB
Write amplification matters: the drive may perform more internal flash writes than the host’s logical writes. RAID parity, filesystem behavior, garbage collection, compression, block sizes and workload patterns can affect the relationship between the application’s writes and flash wear. A read-intensive drive is not “write-proof.” Measure expected writes and consider worst-case patterns, not just average daily data volume. If the workload is dominated by small random writes, logs or cache churn, a higher-endurance drive may be a better fit even if it offers less capacity per device.
Why 61.44TB density can be valuable—and risky
Putting tens of terabytes on one SSD can reduce the number of drive slots, cables and devices needed for a given raw capacity. In a space-constrained system, fewer devices may simplify storage management and make better use of rack space. Density is especially attractive where slots, power, cooling or operational complexity constrain expansion.
But a single 61.44TB drive is also a large failure domain. Capacity does not replace backups, replication, RAID or erasure coding. A failed device can remove a large amount of data at once, and rebuild or replacement time depends on the array design, system load and recovery path. Plan for recovery before deployment: account for spare capacity, redundancy, backup windows and the consequences of rebuilding a large device.
Rank #4
- Solidigm D7 Series D7-P5520 - SSD - 3.84 TB - internal - 2.5" - U.2 PCIe 4.0 x4 (NVMe)
Solidigm promotes rack and power savings for particular configurations. Those claims depend on the comparison system and its assumptions; they are not universal savings. Model your own drive count, redundancy, utilization, power, cooling, rack costs and labor. HDD arrays can still offer much lower raw cost per terabyte for cold data, while hybrid storage can put frequently accessed data on flash and retain colder content on disk. Compare complete systems, not media prices alone.
Compatibility checklist before buying
This is a data-center drive, so electrical NVMe compatibility by itself is not enough. Confirm all of the following with the server, backplane, HBA or RAID-controller vendor and the SSD’s exact model number:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Form factor and bay: The system must accept U.2 15mm or E1.L, as appropriate. A standard consumer M.2 slot is not a substitute.
- Interface and cabling: Verify PCIe 4.0 x4 connectivity, NVMe support, the correct U.2/U.3 cable or backplane, and any required PCIe bifurcation.
- Power and airflow: The drive is rated for up to 25W. Confirm power delivery and server airflow; an adapter in a poorly ventilated desktop enclosure may overheat or throttle.
- Firmware and software: Check BIOS recognition of a very large NVMe device, operating-system support, and whether the filesystem and volume-management stack can use the required volume size. Confirm the exact SSD is supported by the RAID controller or HBA.
- Security SKU: Solidigm and retailer listings distinguish configurations such as FIPS and OPAL or generic/no-OPAL variants. Confirm the required feature and certification for the exact SKU; FIPS applies only to applicable models.
- Warranty and supply: Enterprise warranty terms may depend on model, region, usage limits and seller. Use Solidigm’s product and support page to check the exact product rather than assuming consumer warranty terms.
For a desktop or homelab, the drive is a specialist choice, not a plug-and-play upgrade. A PCIe adapter may solve the connector problem while leaving power, cooling, mounting, firmware and operating-system compatibility unresolved. Do not buy until the complete path has been validated.

Reliability and data protection
Solidigm lists power-loss protection, full data-path protection, ECC coverage for 99% of SRAM, UBER below one sector per 1017 bits read and a two-million-hour MTBF. It also cites silent-data-corruption testing across more than six million simulated drive-years with no observed events. These are manufacturer ratings and test claims, not guarantees that an individual device will not fail. MTBF is a population statistic, not a predicted service life for one SSD. FIPS 140-3 Level 2 availability likewise applies only to the appropriate SKU and certification status.
Alternatives to consider
| Alternative | Consider it when… |
|---|---|
| Solidigm D5-P5316 | You want a lower-capacity, read-optimized PCIe 4.0 option and can distribute storage across more drives. |
| Solidigm D5-P5430 | A mainstream read-intensive drive with capacity up to 30.72TB is enough; 61.44TB per device is unnecessary. |
| Solidigm D7-PS1010 | You care more about PCIe 5.0 bandwidth and mixed-workload performance than extreme capacity per drive; capacities are much lower than the P5336. |
| Micron 6500 ION | You are comparing another high-capacity, read-oriented enterprise SSD. Compare exact capacity, endurance, form factor, interface, price and availability; the original review’s comparison is not a current market-wide verdict. |
| HDD or hybrid storage | Your data is mostly cold and raw cost per terabyte matters more than latency, random reads or rack density. |
Solidigm’s product page links to its product-family information. Treat comparisons as workload decisions: the D5-P5336’s advantage is capacity density, not superiority in every performance or endurance category.
Price and buying advice
Enterprise SSD pricing varies by seller, security configuration, availability and negotiated volume. Two U.S. retail signals illustrate why a single “street price” can mislead: CDW listed the U.2 FIPS SKU SBFPF2BV614TOF1 at $27,316.99 (about $444.61 per TB) on August 12, 2026, while a Newegg marketplace listing showed the generic/no-OPAL SKU SBFPF2BV614T001 at $33,249 (about $541.16 per TB) on August 18, 2026. These are dated listing prices, not a stable quote or guarantee of current stock.
Check the exact SKU, seller, warranty and delivery terms before ordering. The FIPS and generic configurations are not interchangeable if a deployment has compliance requirements. For enterprise quantities, ask the reseller for a quote and confirm compatibility with the server manufacturer.
Quick Recap
Who should buy it?
| Workload or buyer | Fit |
|---|---|
| Read-heavy data lake or analytics repository | Strong candidate if capacity density and fast reads justify the cost. |
| AI dataset serving | Strong candidate when datasets are read repeatedly and the platform supports the drive. |
| VDI boot and login workloads | Potential candidate; validate performance on the intended host and workload. |
| Sequential ingest with modest writes | Potentially suitable if write volume and endurance fit the deployment. |
| Transactional database or log-heavy service | Usually look for higher write endurance and validate latency under the actual write mix. |
| Write cache or scratch disk | Poor fit for sustained write-heavy use. |
| Gaming PC or ordinary desktop | Poor fit: enterprise form factor, cost, power, cooling and support expectations are mismatched. |
| Homelab NAS | Only for a specialist build that can support U.2/E1.L, airflow and the price of enterprise storage. |
