Swissbit SSDs as diagnostic device for host issues

Issues with a host computer PCIe bus interface or its power supplies can cause the host/SSD interface to unexpectedly no longer recognize an operating SSD. If this occurs, that SSD is described as having fallen off the bus.

There are three possible reasons for this:

  1. Unrecovered Bus Link Loss
  2. Brownout
  3. SSD Firmware Error/Hang

If a Swissbit SSD falls off the bus, the drive can be used as a diagnostic device to determine the cause. Better yet, Swissbit NVMe SSDs diagnose and report on every isolated occurrence, without the need to replicate the issue. This information can then be shared with the host designer. Swissbit SSDs can be used for this purpose at any time in the field.
