512TB SSD: What Exists, Price & Availability
A 512TB SSD is no longer just theoretical, but it is not yet the same thing as a drive you can price like a normal retail SSD. DapuStor's R6060 is the sourced half-petabyte example in DatacenterDisk's current product-status table.
This page answers the generic buyer question: what exists, who makes it, whether you can buy it, and how to compare it against currently priced enterprise SSD capacity.
| SSD | Capacity | Interface | NAND | Form factor | Commercial status | Current price |
|---|---|---|---|---|---|---|
| DapuStor R6060 512TB AI datasets, scale-out storage and dense capacity flash | 512TB | PCIe 5.0 NVMe 2.0 | Enterprise QLC | E2 / E3.L, per FMS 2026 material | Demonstrated This capacity has been publicly demonstrated but is not yet broadly available for purchase. | Not yet available |
Does a 512TB SSD exist?
Yes, in the sense that DapuStor has shown a 512TB R6060 PCIe 5.0 QLC enterprise SSD configuration and describes the capacity in its product material. That makes it a sourced high-capacity product claim, not an imaginary capacity.
Existence is not availability. DatacenterDisk keeps the 512TB status separate from shipping and current-price status because buyers need to know whether a model can actually be transacted today.
Can you buy a 512TB SSD today?
No public transactional price is currently shown for an exact 512TB SSD. If one appears, this page can show the exact product, condition, price, $/TB, retailer path and Buy/View Price button.
How much would a 512TB SSD cost?
The honest answer is that there is no public transactional 512TB SSD price shown here. A capacity-equivalent comparison can still be useful as long as it is labelled correctly.
At today's enterprise NVMe median of $580.82/TB, 512TB of flash would cost about $297,380 using currently priced drives. This is not a product price for the DapuStor 512TB SSD.
These are current enterprise SSD prices shown on DatacenterDisk. They are alternatives or reference points, not substitutes for unpriced announced products.

512TB vs 245TB vs 122TB
The value of 512TB is device-count compression. Two 512TB drives reach roughly the same raw class as five 245.76TB drives or nine 122.88TB drives. For data-center planning, fewer devices can reduce slots, power paths and failure domains, but it also concentrates more data per device.
| Drive capacity | Drives for 1PB raw | Drives for 10PB raw |
|---|---|---|
| 122.88TB | 9 | 82 |
| 245.76TB | 5 | 41 |
| 512TB | 2 | 20 |
Two 512TB SSDs equal approximately 1PB raw
| Capacity arithmetic | 2 x 512TB = 1,024TB raw |
|---|---|
| Raw versus usable | Usable capacity is lower after protection, metadata, spare and filesystem overhead. |
| Price rule | Do not infer the price of a specific 512TB SSD from unrelated lower-capacity $/TB rows. |
Frequently asked questions
Does a 512TB SSD exist?
A 512TB enterprise SSD has been demonstrated and shown in DapuStor R6060 material. That is a real sourced capacity claim, but it is not the same as broad retail availability.
Which company makes a 512TB SSD?
DapuStor is the sourced 512TB SSD vendor in this DatacenterDisk cluster, through the R6060 PCIe 5.0 QLC enterprise SSD family.
Can you buy a 512TB SSD today?
No exact 512TB SSD currently has a public transactional price shown here. The page will show current price data only when a real public offer exists.
How much would a 512TB SSD cost?
There is no public MSRP shown here for the DapuStor 512TB SSD. The page can show a theoretical capacity-equivalent cost from current enterprise NVMe $/TB, but labels it as a mathematical comparison.
For live purchase decisions, use enterprise NVMe prices. For fleet budgets, model flash with the AI memory CAPEX calculator.
