Linux and Unix Test Disk I/O Performance With dd Command

Oct 12, 2015 · Hi everybody, i know that this is not specific to proxmox but i am always finding good help here so i try anyway if the staff is ok :) I have a proxmox running on a machine with 6 disk in raid10 + 1 spare the disk were connected to a lsi 9211-8i and i always had strange logs so i decided to The first speed shows how fast disk reads are if the data is already buffered. The disk is never accessed, so it is probably pretty meaningless for a web server (since most of the time disk reads will probably not be buffered). The second stat shows real hard drive read performance. In your case, it means that the web server is reading under 1 Apr 30, 2020 · My WD Blue N550 1TB uses 512B sectors “out of the box”. So I often read modern drives are using 4096B sectors, but in special SSDs need it because its their internal size. If using 512B sectors this would also make double write cycles and so shorting the lifetime of the drive. So, my smartctl output says: Supported LBA Sizes (NSID 0x1) Id Fmt Data Metadt Rel_Perf 0 + 512 0 2 1 - 4096 0 1 Mar 05, 2010 · Timing cached reads: 1512 MB in 2.02 seconds = 750.01 MB/sec Timing buffered disk reads: 154 MB in 3.03 seconds = 50.76 MB/sec /dev/ram1: Timing cached reads: 1350 MB in 2.00 seconds = 674.96 MB/sec Timing buffered disk reads: 16 MB in 0.03 seconds = 561.60 MB/sec
