Solidigm announced it on November 13, 2024, initially describing customer sampling and early-2025 availability. A May 2025 report confirmed the 122.88TB U.2 version was on sale. As of August 18, 2026, Solidigm still lists the drive, but channel stock, form-factor availability and pricing vary.
This is a specialized PCIe 4.0 QLC data-center drive for dense, read-intensive storage—not a consumer, gaming or general-purpose replacement for TLC SSDs.

What the D5-P5336 actually is
The Solidigm D5-P5336 is an enterprise NVMe SSD built with 192-layer quad-level-cell (QLC) NAND. Its largest version provides 122.88TB of user capacity, which is why it is commonly called a “122TB SSD.” The precise capacity and original availability language appear in Solidigm’s November 2024 announcement and product materials.
QLC stores four bits per NAND cell. That increases capacity and lowers the number of drives needed for a petabyte-scale deployment, but generally provides less write endurance and less forgiving sustained-write behavior than performance-oriented TLC products. Solidigm therefore positions the P5336 for capacity tiers where read throughput, watts per usable terabyte and rack density matter more than maximum write performance.

Launch timeline: announcement versus commercial availability
- November 13, 2024: Solidigm announced the 122TB-class D5-P5336 and said it was sampling to customers.
- Early 2025: The company’s original plan called for availability in Q1 2025, with U.2 and E1.L versions identified for the 122TB class.
- May 23, 2025: TechRadar reported that the 122.88TB U.2 model had officially gone on sale.
- August 18, 2026: Solidigm’s homepage continues to present the 122TB drive as available, while its older product page still contains the historical early-2025 wording. Availability should therefore be checked by exact SKU and form factor.
“Available” can mean a distributor listing, qualification stock, quote-only supply or inventory in one region. It does not guarantee that every U.2, E1.L or E3.S configuration is simultaneously in stock.

Solidigm’s product brief reports up to 7.4GB/s sequential read in cited CDN and object-storage comparisons. In a cited general-purpose-server workload, the 122.88TB model delivers approximately 6.1GB/s total bandwidth. Product-page and secondary reports place 4KB random-read performance around 930,000 to 1,005,000 IOPS, depending on configuration and source.
The brief’s comparison table shows the 122.88TB drive performing close to the 61.44TB model in simulated CDN, general-purpose-server, object-storage and write-pressure workloads. The figures come from specified vendor tests and simulations using particular servers, CPUs, operating systems, FIO versions, transfer sizes and workload definitions. They should not be treated as guaranteed results on every server or array.

Why QLC makes sense at this capacity
At 122.88TB, the primary benefit is storage density. Fewer devices can mean fewer drive bays, cables, controllers, replacement events and watts consumed by the storage tier. QLC is not automatically unsuitable for enterprise use; the deciding factors are write rate, latency targets, data temperature, endurance policy and redundancy design.
Solidigm’s modeled density claims
In a modeled 16PB NAS comparison, Solidigm says an all-QLC D5-P5336 design could reduce storage requirements from nine racks to one, use about 90% less storage power and free enough power for roughly 50% more compute capacity. The announcement also cites up to 4PB per rack unit and up to a 4:1 NAS-footprint reduction compared with legacy HDD-plus-TLC arrangements.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesThose are modeled comparisons, not universal guarantees. The result depends on the compared drive capacities, servers, networking, controllers, cooling, redundancy, software and workload. A six-drive array also has less usable capacity after parity, replication, hot spares, metadata, filesystem overhead and reserved free space.
“Unlimited random-write endurance” explained
Solidigm’s announcement used the phrase “unlimited Random Write endurance for five years.” That does not mean the NAND is physically incapable of wearing out. The product brief explains that, under specified continuous 100%-duty-cycle tests, the drive retained approximately 5% of its life after five years of 32KB random writes or approximately 10% after 4KB random writes.
The formal published rating remains 0.60 DWPD, or 134.3PB written over five years for the 122.88TB model. Actual wear depends on write amplification, block size, overprovisioning, temperature, firmware, workload mix and system configuration. Treat the “unlimited” wording as a Solidigm claim for defined workloads and a five-year period—not as infinite endurance or a blanket guarantee for every application.

Where the drive fits—and where it does not
| Good candidates | Poor fits |
|---|---|
| AI training-data repositories and inference-data stores | Write-heavy transactional databases |
| Object-storage backends and CDN origin or cache tiers | Logging systems with sustained high write rates |
| Scale-out NAS and large read-heavy analytics datasets | Applications requiring consistently minimal write latency |
| Edge deployments constrained by rack space, power or cooling | Consumer desktops, gaming PCs and ordinary NAS appliances |
| HDD replacement in a performance-sensitive capacity tier | Systems that need PCIe Gen5 throughput above capacity density |
For write-intensive or latency-sensitive services, a higher-endurance TLC SSD—potentially from Solidigm’s performance-oriented D7 family—may be more appropriate even if it provides less capacity per device.

Form factors and deployment requirements
U.2
U.2 fits common enterprise 2.5-inch NVMe bays, but the server still needs a compatible backplane, cabling, PCIe lanes, power delivery and airflow. The May 2025 sale report concerned the U.2 model.
E1.L
E1.L is a long “ruler” form factor designed for high-density hyperscale chassis. It requires an E1.L-compatible chassis or carrier and should not be assumed interchangeable with U.2.
E3.S
E3.S is a compact enterprise form factor. Capacity and availability combinations must be checked against the exact Solidigm SKU rather than inferred from the family name.
Before purchase, qualify the drive in the intended server, confirm firmware and NVMe compatibility, verify the backplane’s power and thermal limits, and design replication, erasure coding, hot spares and fault domains around the much larger amount of data exposed by one device.
Rank #4
- SATA drive with capacity up to 7.68TB and standard durability
- Designed for increased server efficiency for cloud storage and IOPS/TB performance significantly exceeds traditional hard disk drives (HDDs)
- Interface : SATA 3.0 6GB/S
- Form Factor : 2.5" 7MM
Pricing is a procurement question, not a stable MSRP
TechRadar reported a Tech-America listing at $12,399 on May 23, 2025. A later retrieval of the Tech-America product page showed $41,831 and out of stock. These are dated reseller snapshots, not a dependable manufacturer MSRP. Enterprise SSD pricing can vary with region, allocation, warranty, lead time and negotiated volume.
For a current quote, use Solidigm’s authorized distributor locator. Listed procurement routes include Arrow Electronics, Avnet, ASI Computer Technologies, Ingram Micro, Mouser, TD Synnex and WPG, although stock and lead times must be confirmed directly.
Evaluate the purchase by cost per usable petabyte, watts per usable terabyte, rack units, read QoS under write pressure, endurance, rebuild exposure and controller or networking costs—not by the drive’s headline capacity alone.
Capacity concentration and failure-domain risk
Replacing many smaller SSDs with 122.88TB devices simplifies a capacity tier, but each failure affects more data. Arrays need adequate replication or erasure coding, hot spares and rebuild plans. A drive-level 134.3PBW rating does not guarantee array-level rebuild durability, controller compatibility, latency under every workload or performance when the drive is nearly full.

Pick the symptom - the matching free tool is one click away.
Likewise, Solidigm’s launch-era “world’s highest-capacity PCIe SSD” language is time-sensitive. It should be understood as a dated company positioning claim, not a permanent industry ranking.
Verdict
The D5-P5336 is a meaningful enterprise-density product that did ship after its early-2025 announcement. Its 122.88TB capacity can reduce device count, rack space and storage-tier power in read-heavy deployments. Its trade-offs are equally clear: PCIe 4.0 rather than Gen5, QLC-oriented write endurance, specialized form factors, concentrated failure impact and highly variable enterprise pricing.
For AI data lakes, object storage, CDN infrastructure and other capacity tiers, the right comparison is cost and power per usable petabyte at the system level. For consumer PCs, write-heavy databases or latency-critical services, the 122TB headline is not a reason to replace a suitable TLC SSD.
