matgeo Posted July 31, 2018 Share Posted July 31, 2018 Hi there. I'm facing a problem with low write speeds on my Intel 540s 120GB ssd. This issue happens on High Sierra 10.13.6 and on Mojave 10.14 , too. It happens also on hfs+ and apfs. Here is a screenshot of the speeds. Need your advice. Thank you.

Allan Posted July 31, 2018 Share Posted July 31, 2018 Did you plug it to a SATA-6 port? AHCI mode in UEFI/Bios? Link to comment https://www.insanelymac.com/forum/topic/335036-ssd-slow-write-speed/#findComment-2628262 Share on other sites More sharing options...

matgeo Posted August 1, 2018 Author Share Posted August 1, 2018 I enabled trim just to see if anything changes. Benchmark is the same with trim disabled , also in apfs and hfs+. Maybe is something wrong with my Intel 540s ? Intel SSD toolbox shows good health.

matgeo Posted August 2, 2018 Author Share Posted August 2, 2018 I recovered high Sierra (so as to have the same configuration ) to a Samsung 830 64gb. Here are the results. I think 160mb/sec is the top of Samsung 830 64gb. Link to comment https://www.insanelymac.com/forum/topic/335036-ssd-slow-write-speed/#findComment-2628487 Share on other sites More sharing options...

dimitris Posted August 4, 2018 Share Posted August 4, 2018 Sure. My ticket is still open. Haven't heard any news. Doubt that Intel will replace my ssd. I'm sure that will say that drive operates well. Link to comment https://www.insanelymac.com/forum/topic/335036-ssd-slow-write-speed/#findComment-2628692 Share on other sites More sharing options...
