To me the real thing missing is whether those drive advertise power loss protection or not. The next question is whether they are to be used in a laptop where power loss protection is less relevant given the local battery.
- jtwaleson 3y agoThat should be irrelevant, because flush is flush right? If your SSD does not write the data after a flush it's violating basic hard drive functionality.
- HankB99 3y agoGP has a point in that a laptop is much less likely to experience unplanned power loss because of the built in battery. However that does not help desktops which also use NVME SSDs. The other problem is that this doesn't only cause problems resulting from power loss. At least some files systems guarantee consistency of data on the drive by flushing at critical points. ZFS on Linux does this. If the flush doesn't happen as promised, subsequent writes could result in corrupted files should something else like a crash interrupt operation.
