noisegate Posted July 7, 2014 Share Posted July 7, 2014 Hi all,I have a hackintosh with 2 840 EVO SSD’s inside, and their read times gradually slow down A LOT.'Freshly' written files on the SSDs do show normal read rates.With files a few months old, AJA shows read times as low as 65MB/s...Write tests are fine, I only notice a strong read degradation over time.This is specific to those Samsung SSDs, I also have 2 smaller M4s installed with no such issue.AHCI on, trim on, no filevault, no spotlight indexation, no sleep, lots of free space available on the SSDs. Connected to SATA 3 ports, latest firmware.Specs: X79 deluxe, 4930k, HD 6870 with OSX 10.9.4Anyone with a similar problem?Thx Link to comment https://www.insanelymac.com/forum/topic/299355-samsung-840-evo-slow-read-times/ Share on other sites More sharing options...
ludacrisvp Posted July 25, 2014 Share Posted July 25, 2014 Mine needed a firmware update for the SSD, fixed most of the performance issues I had with mine.
