[QUOTE="Randy B. Singer, post: 1927087, member: 190607"] I don't have any experience with WD Blue SSD's. But I have a prejudice against WD in general, because it always seems that if there is some way that WD can screw you...they will. So, before you purchase that WD SSD, ask a lot of questions: Does it include DRAM? (Garbage SSD's leave out the DRAM to save money. This slows them down precipitously. How much over-provisioning does it have? (A cheaply made SSD may have NONE. Which means that your SSD will be fast when new, but quickly drop off in performance.) Does it work with Apple's implementation of TRIM? (If it doesn't, your SSD won't have a very long lifespan, and it will, once again, drop off in performance much earlier in its life than it should.) Is this model compatible with your model of Mac? [URL unfurl="true"]https://beetstech.com/blog/apple-proprietary-ssd-ultimate-guide-to-specs-and-upgrades[/URL] What is the rated IO speed of this SSD?
