From local NVMe to shared datasets and checkpoints: understand which storage characteristics matter for AI infrastructure.
A fast accelerator can still wait on storage. Dataset reads, small-file access, model loading and checkpoint writes create different demands. Size the storage path around those operations.
Samsung’s PM1743 is an enterprise PCIe 5.0 SSD family. Use the exact capacity and form-factor specification when checking throughput, endurance and server compatibility.
Evaluate: the host interface, cooling, firmware support and the server’s qualified drive list.
Samsung PM1743 product pageMicron lists sequential performance up to 14 GB/s read and 10 GB/s write for the 9550 family. Those headline figures are not a promise of application performance across every capacity or workload.
Evaluate: sustained mixed I/O, write endurance and latency under load.
Micron 9550 specificationsKIOXIA’s CM7 family includes read-intensive and mixed-use enterprise options. Match the endurance class to the write workload rather than selecting capacity alone.
Evaluate: the exact model, form factor and required host connectivity.
KIOXIA CM7 family briefNVMe inside a server can hold a local dataset cache, temporary files or checkpoints. Plan how important data survives a node failure.
A shared file or parallel storage system gives multiple workers access to data. Measure aggregate throughput and metadata operations under concurrent load.
Use durable storage for source datasets, model artifacts and recovery copies. Include retention, restore time and transfer costs in the design.
| Term | What it describes | Check before buying |
|---|---|---|
| PCIe | The electrical link and generation | Available lanes and host generation |
| NVMe | The storage command protocol | OS, controller and firmware support |
| U.2 / U.3, E1.S, E3.S, M.2 | Physical and connector families | Exact backplane, carrier, slot and thermal compatibility |
| DWPD / TBW | Write-endurance ratings | Expected writes over the rated warranty period |
Two drives with the same capacity may have different endurance, power-loss protection and sustained performance. A matching connector alone does not establish compatibility.
