245TB SSDs: Models, Prices & Availability
245TB SSD searches usually mean the 245.76TB enterprise NVMe class. These drives are built for hyperscale capacity, AI data lakes, object storage and analytics rather than desktops or consumer workstations.
The key buyer distinction is status. Micron 6600 ION has an explicit first-party shipping statement; KIOXIA LC9 and DapuStor R6060 variants are useful capacity peers, but each row keeps its own availability label.
| SSD | Capacity | Interface | NAND | Form factor | Commercial status | Current price |

245TB SSD models
The 245.76TB class is where enterprise flash starts to compete on device count rather than only speed. The Micron 6600 ION uses PCIe Gen5 and QLC NAND. KIOXIA LC9 is listed as a 245.76TB E3.L high-capacity SSD. DapuStor's R6060 family also lists 245.76TB EDSFF configurations alongside the 512TB headline.
The page does not rank unpriced products by value. Value is calculated only from current public prices.
Is there really a 256TB SSD?
Buyers will see both 245.76TB and 256TB language. Micron's own material distinguishes 245.76TB usable capacity from 256TB raw capacity. DatacenterDisk uses the marketed capacity for $/TB math and calls out raw capacity only when the vendor uses that wording.
245TB SSD price
Enterprise drives at this capacity may be sold through OEM and direct channels rather than normal public carts. If a current transactional offer is available, the table above will show the price, $/TB, condition, retailer path and Buy/View Price CTA. Without that offer, the page reports the product as unpriced.
These are current enterprise SSD prices shown on DatacenterDisk. They are alternatives or reference points, not substitutes for unpriced announced products.

245TB SSD vs 122TB SSD
A 245.76TB drive roughly halves the device count versus 122.88TB. For 1PB raw, DatacenterDisk calculates five 245.76TB SSDs versus nine 122.88TB SSDs. For 10PB raw, that becomes forty-one drives versus eighty-two. Real usable capacity still depends on protection and reserve.
| Drive capacity | Drives for 1PB raw | Drives for 10PB raw |
|---|---|---|
| 122.88TB | 9 | 82 |
| 245.76TB | 5 | 41 |
| 512TB | 2 | 20 |
AI storage role
245.76TB SSDs are capacity flash. They fit large AI data lakes, vector indexes, object stores, high-throughput preprocessing and analytics where hard-drive latency or device count is the bottleneck. They are not the same class as memory-extension flash like KIOXIA GP1.
How to read availability status
| Shipping to customers | A manufacturer has explicitly stated commercial shipment. |
|---|---|
| Listed by manufacturer | The capacity appears in a current vendor product table, but broad commercial availability has not been confirmed. |
| Current public price | A current public offer is available for buying and $/TB comparison. |
Frequently asked questions
Is there a 245TB SSD?
Yes. Micron 6600 ION reaches 245.76TB usable capacity, and other manufacturer product families list 245.76TB-class configurations. Availability status differs by product.
Is the Micron 6600 ION 245TB shipping?
Micron published a May 2026 release saying the 245TB 6600 ION is now shipping, which is why DatacenterDisk treats it as the clearest shipping benchmark in this class.
Is a 245.76TB SSD the same as a 256TB SSD?
Not exactly. Micron describes 245.76TB usable capacity and 256TB raw capacity. DatacenterDisk keeps marketed usable TB and raw NAND wording separate.
How many 245.76TB SSDs make 1PB?
Five 245.76TB SSDs provide 1,228.8TB raw, enough to exceed a 1PB decimal raw target before protection overhead.
