Is there anyway to sanitize/purge the whole drive that “nvme list” in linux shows 0 bytes usage again for the namespace? And or the WD dashboard shows 0 again?
Is there a way to resize the namespace with WD dashboard & overprovision the drive to increase performance?
Is “sanitize / secure erase” of WD Dashboard supported for SN550 and it currently just doesnt work because of my KVM mapping?
Is “sanitize / secure erase” of WD Dashboard fixing the namespace utilization?
Why is the drive in “hard”=sustainted benchmarks only reaching write speeds of about 5MB/sek?
Read speed is even for “hard” benchmarks pretty good, so it must be the hardware…
I tried to sanitize, secure erase it and on top i was running trim by windows.
I would be expecting now that the drive is “fully” empty and the namespace usage would drop to almost 0.
Sadly windows created me some trouble, by installing security updates and restarting the machine… Also im preferring now the CLI tool instead the UI tool of “ezfio”. Benchmark is still running though…
As you can see here those drives have sustained writes of less then 30MB/s even under windows.
We wanted to use those drives in our startup creating a cloud computing project and already installed those in the servers in our datacenter. We feel very disappointed by WD by comparing it against this datasheet:
We bought 20 of those drive, which is very unusable now for us.
@Keerti_01 Please explain where this huge gap between real usage and your datasheet is coming from. We were expecting much more from a TLC drive.
