How we pick replacements

Every recommendation above was selected using these criteria:

  • Drop-in compatibility — same form factor (2.5"/3.5", PCIe slot, SFP port, etc.), so it fits the original chassis without modification
  • Equivalent or better performance — matched on RPM/IOPS/speed/throughput, never downgraded
  • Same-brand-preferred — we list the OEM-equivalent first when available, then trusted aftermarket
  • Warranty coverage — 90-day Pro Disk warranty on every part, with 1-year option for B2B
  • In stock today — never recommend a part that is on backorder

Need help confirming compatibility?

Our engineers validate every replacement against your specific server, switch, or chassis model before shipment. Email sales@prodisknetwork.com with your platform model (e.g., Dell PowerEdge R740, HP DL380 Gen10, Cisco Catalyst 9300) and we will confirm the exact part number that drops into your hardware.
