A card with it’s indicated capacity but high error rate/slow write speed indicates a ‘ghost run’.
#CRYSTAL DISK SPEED TEST FULL#
H2testW tests the full capacity of the Micro SD card and will report if any are using aliasing to fake larger than real capacity. Test with ChkFlsh, Crystal Disk Mark & the main one H2testW. Some fakes will still pass some of the test programmes. You will most likely get a genuine card, but there are many fakes so its essential you test your card when you receive it. I think it’s useful and have copied it here for others to see in case the original is removed. Random Write 4KiB (Q= 1,T= 1) : 8.I saw this method for testing micro sd cards on an Amazon review while searching for Micro SD cards. Today I added intel P3700 400 GB for slog for my storage (raidz1 - 8 x Intel SSD D3-S4510 1.92TB) below results I'm not sure what is between 2 RAIDZ1 mirror or stripe, one SSD has 1.92 GB so looks like stripe
#CRYSTAL DISK SPEED TEST WINDOWS 10#
OS : Windows 10 Professional (圆4)Īaa write is boosted via RAM :) below scores for 32 GiB size and sync=always for ZVOL. So I don't know if this is a hard cap or some other tunable that need to be set.ĬPU: Intel(R) Xeon(R) CPU E5-1620 v4 3.50GHz (8 cores)ĭisk: 12 Disk, 3x vdev, RaidZ2 4x HGST 600GB 15k RPM
I've got a similar server and I found it was reading from RAM during the read side of the test. Sequential Read (Q= 32,T= 1) : 548.314 MB/s - Sequential Read is worse than Sequential Write?
Please let me know is it good score or not, and what I can do to improve iSCSI performance form example Logical block size etc
I have tested my iSCSI storage for VMware, below platform details and test results.
