122TB SSDs: Models, Prices & Availability
122TB SSD usually means a 122.88TB enterprise NVMe drive. This capacity class is important because it is high enough for single-node petabyte flash builds while still appearing in established data-center product families.
This page separates product status from public pricing. A sourced 122.88TB model can be commercially available or listed by its manufacturer while still lacking a public offer.
| SSD | Capacity | Interface | NAND | Form factor | Commercial status | Current price |
|---|---|---|---|---|---|---|
| DapuStor R6060 122.88TB High-density AI and cloud data storage | 122.88TB | PCIe 5.0 NVMe 2.0 | Enterprise QLC | U.2 / E3.L | Listed by manufacturer The manufacturer lists this capacity, but broad commercial availability has not been confirmed. | Price unavailable |
| KIOXIA LC9 122.88TB Capacity-optimized enterprise flash | 122.88TB | PCIe 5.0 NVMe 2.0 | BiCS FLASH QLC | E3.S / 2.5-inch | Listed by manufacturer The manufacturer lists this capacity, but broad commercial availability has not been confirmed. | Price unavailable |
| Micron 6600 ION 122.88TB Dense capacity flash where the 245.76TB E3.L chassis is not the right form factor | 122.88TB | PCIe 5.0 NVMe | Micron G9 QLC | E3.S / U.2 | Available Available through enterprise suppliers; pricing may require a quote. | Quote required |
| Solidigm D5-P5336 122.88TB AI datasets, object storage, CDN, scale-out NAS and data lakes | 122.88TB | PCIe 4.0 NVMe | QLC | U.2 / E1.L / E3.S by capacity | Available Available through enterprise suppliers. | Price unavailable |
122TB SSD models
The 122.88TB class includes both established QLC capacity drives and newer high-capacity Gen5 families. Solidigm D5-P5336 is the durable PCIe 4.0 reference. Micron 6600 ION and DapuStor R6060 move the class into PCIe 5.0. KIOXIA LC9 is a high-capacity QLC entry listed in KIOXIA's enterprise SSD product table.
Do not compare all of these as if they were identical. Interface generation, form factor, indirection-unit size, endurance class and actual purchase availability matter.
122TB SSD price
When exact 122.88TB products have a current public price, this page surfaces the price and $/TB. When they do not, it shows product status and current enterprise NVMe alternatives instead. That prevents a quote-based or unavailable product from becoming a fictional price.
These are current enterprise SSD prices shown on DatacenterDisk. They are alternatives or reference points, not substitutes for unpriced announced products.

122TB SSD use cases for AI storage
A 122.88TB SSD is most useful as capacity flash. It can hold training corpora, vector-store shards, retrieval datasets, object-storage nodes, checkpoint repositories and large content libraries where random access matters more than the lowest possible raw $/TB.
For many AI systems this is not a replacement for HBM or system memory. It is a dense, fast persistence tier between memory and lower-cost disk or tape.
122TB SSD vs 30TB HDD
One 122.88TB SSD roughly replaces four 30TB hard drives on raw capacity, but that is not the whole comparison. The HDD set may win on acquisition cost per terabyte, while the SSD wins on device count, random access, power per terabyte and slot density. Use good price per TB for current HDD context and NVMe U.2 for live flash pricing.
122TB vs 245TB SSD
A 245.76TB SSD cuts the device count roughly in half versus 122.88TB. The trade is chassis support, availability and quote-based procurement. If 245.76TB is unavailable or too hard to qualify in a platform, 122.88TB can be the practical dense-flash ceiling.
| Drive capacity | Drives for 1PB raw | Drives for 10PB raw |
|---|---|---|
| 61.44TB | 17 | 163 |
| 122.88TB | 9 | 82 |
| 245.76TB | 5 | 41 |
Capacity formula table
| Raw fleet capacity | Drive count x marketed TB |
|---|---|
| Drives for 1PB raw | ceil(1000 / drive capacity TB) |
| $/TB | Current public price / marketed TB, using DatacenterDisk's existing convention |
| Usable capacity | Depends on RAID, erasure coding, filesystem overhead and reserved space. |
Frequently asked questions
What is a 122TB SSD?
Most 122TB SSD searches refer to 122.88TB enterprise NVMe SSDs. These are decimal marketed capacities for data-center drives, not consumer SSDs.
Which 122.88TB SSDs are covered here?
This page covers sourced 122.88TB-class families including Solidigm D5-P5336, Micron 6600 ION, DapuStor R6060 and KIOXIA LC9 where first-party product data supports the capacity.
Can I buy a 122TB SSD at a public price?
Only when a current public offer is available. Otherwise the product remains listed by its commercial status: available, shipping, listed by manufacturer, or unpriced.
How many 122.88TB SSDs make 1PB?
Nine 122.88TB SSDs provide 1,105.92TB raw, which is enough to clear a 1PB decimal raw target before protection overhead.
