Crystal disk speed test6/21/2023 ![]() ![]() 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 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 Information about the test system can be found at the bottom of the home page.Īs an Amazon Associate I earn from qualifying purchases.I have tested my iSCSI storage for VMware, below platform details and test results. The benchmark test was performed on January 18, 2023. Similar to HD Tune, a 500 MB file is written to the Crucial M.2 SSD here. The larger the blocks, the faster they can be written and read. The I/O block size varies (from 512 bytes to 64 megabytes). ![]() Here, a 256 MB file is written several times to the Crucial M.2 SSD. The determined access time and burst rate are also displayed. The minimum, maximum and average values are also determined. The transfer data of the read speed is displayed graphically. HD Tune writes a 5 GB file to the Crucial M.2 SSD. 250 GB, the pSLC-Cache was full and the performance was throttled.Īt least the test file could be read with an average write speed of 2328 MB/s and written with 546 MB/s. You can see when a cache is full and the writing performance decreases.Ī test file of 300 GB was written to the medium.Īfter approx. A long-term test was performed here to make full use of the memory capacity. ![]()
