hello everyone,
Does anyone have some trouble with SSD write speed? I have installed Mojave on my Optimac ( i7-4790, 8g ram, RX 580), all is working well, but write speed on the SSD (a kingston A400 256GB ), is very slow with BlackMagic. Sometimes, firsts test are good, (about R 300 Mb/s), but after 4-5 test, the speed slows down and speed is about 45 Mb/s. I have TRIM enabled (trimforce enabled+ chameleon), tested with Clover trim patch enabled/disabled + trim for third party, but always the same.. the SSD's health is good (verification with Disk Sensei), and empty storage is about the half (140GB of 256Gbs)
I have another 3.5 classic HDD of 2TB, there is no problem about write speed, he is faster than the SSD..
i have seen that this SSD brand is not very good, especially for write speed..
I need your help... Maybe I have to do another clean install but in HFS+, what do you think?
