I'll file a report on bugzilla and hope someone takes the time for it.Software that’s so powerful you‘ll wonder if it’s… magic. If it's a kernel bug it has been there since 4.10. Timing buffered disk reads: 1028 MB in 3.01 seconds = 342.02 MB/secĮverything else in the test system was kept equal. Timing buffered disk reads: 1302 MB in 3.00 seconds = 433.43 uname sudo hdparm -Ttv /dev/sdb Timing buffered disk reads: 1308 MB in 3.00 seconds = 435.76 hdparm -VĮDIT 4: It's the kernel!! uname sudo hdparm -Ttv /dev/sdb Timing cached reads: 15580 MB in 2.00 seconds = 7795.60 MB/sec On a live iso of Ubuntu 16.04.1 hdparm measures different values! sudo hdparm -Tt /dev/sdb I just tested the SSD with the same program on Windows and the results are the same as back then! I found this old post of mine where the same disk was performing way better on linux and on the same laptop. So, at the moment the following can be rooted out as cause of the difference in performance: I also tested with the latest Debian live iso as well as with Ubuntu 16.04.7 iso and installed the 5.10.10 mainline kernel. So it doesn't seem to be about hdparm not being comparable to CrystalDiskMark. MB/sec Timing buffered disk reads: 1454 MB in 3.00 seconds = 484.59 The same disk was measured to 485 MB/sec using hdparm here: lptp : sudo hdparm -Tt /dev/sda ata2.00: supports DRM functions and may not be fully accessible ata2: SATA link up 6.0 Gbps (SStatus 133 SControl 300) SATA controller : Intel Corporation 6 Series/C200 Series Chipset Family 6 port Mobile SATA AHCI Controller (rev 04) SATA Version is: SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s) ~$ smartctl -d ata -x /dev/sdb | grep "SATA\|Firmware"įirmware Version: M0CR070 # <- latest firmware Timing buffered disk reads: 1038 MB in 3.00 seconds = 345.86 MB/sec ![]() Timing cached reads: 16474 MB in 1.99 seconds = 8269.94 MB/sec ![]() These are the results:ĬrystalDiskMark 8.0.0 benchmark results of Crucial_CT750MX300SSD1 /dev/sdb6 My Crucial MX300 750MB is performing a lot better on Windows than on Linux and I can't find out why. ![]() I hope someone can give me a hint about where to look for. ![]()
