Samsung 256TB And 512TB PCIe 6 SSDs Are On The Storage Horizon For Massive Capacity And Bandwidth

At FMS 2025, Samsung has debuted its next generation of server-grade PCIe storage with the Samsung MVP PCIe 6 SSD, available in capacities of 256TB and 512TB. That's no typo, either—we're looking at up to 512 terabytes of storage per drive, or half an entire petabyte. While we don't yet know the final storage speed specification of these PCIe 6 SSDs, we have a pretty good idea of how they'll perform based on how the PCIe 6 standard builds upon PCIe 5. Per-lane bandwidth has doubled with each generation of PCI Express, and Micron's 9650 PCIe 6 SSDs have already been observed reaching real-world speeds as high as 28 GB/s. This means we can expect Samsung's SSDs to reach roughly the same range, and this is still the early days of the tech; one day, we may even see single PCIe6 SSDs ...
