WD Red SMR v. CMR Part II: The Not So Good Our synthetic enterprise storage benchmark process begins with an analysis of the way the drive performs during a thorough preconditioning phase. Each of the comparable drives are secure erased using the vendor’s tools, preconditioned into steady state with the same workload the device will be tested with under a heavy load of 16 threads with an outstanding queue of 16 per thread, and then tested in set intervals in multiple thread/queue depth profiles to show performance under light and heavy usage. First up is the file copy test. Just a reminder, this test was performed as immediately as possible after completing the drive preparation process.

WD supplied StorageReview with 5 samples of both new drives, which we configured in RAID5 in our Synology DiskStation DS1513+. Leveraging SMB/CIFS shares we show how well a 50GB test sample size performed on each storage array we created.
