Capacity per price ratio: HDD still offers the best ratio. For the cheapest 2.5 inch 1TB (Marketed as 960GB) SATA SSD, you can buy close to 4TB 3.5 inch HDD.
Resilient: SSD has no moving parts, so it is not prone to vibration shock or drop like HDD.
Speed: You know by now. However, I would like to add something that many may not talk about it: The Write Speed, or writing to an SSD in general. Writing to SSD actually is a bit different than HDD. For HDD, it can override the existing data just like it was writing a data on a empty space. For SSD, if there's data in the place it needs to write, it needs to purge the data first then only it can write, which you will see a dramatic speed drop if you write a lot of data (over the stated capacity). Fortunately, there's a trim function where you can purge the deleted file space.
Data recoverability: This is up to debate, but let's say if your drive died, and you need to recover the data. Usually, for HDD, the data can be recovered easier as the HDD platter can be swapped to a new controller. SSD, on the other hand are a bit difficult, as the chip is soldered to the board, which it needs to be removed from the board and soldered into the new controller. Also, if there's a spike in the power rail and if the chip is burnt, the data is very hard to recover.
Longevity: This is also up for debate. I can't say much because I don't have any experience.
Heat: Up to debate, but I found certain SSD generate quite amount of heat (still in the warm range of about 40c). However, most stays pretty cool.
So, this is through my experience. The SSD is super fast (even for the SATA one). It is pretty much light and consume way less power. It all boils down to what purpose your are going to use, however, whether you need the capacity or the speed.
Thx both of u for helping me out I really appreciate it, btw sorry I meant to say if one stick will work if u have 2 slots not if it will work in a dual memory channel lol
