I have been looking at the best options to implement ssd's into my mac pro in a way where the speed benefit will be great and noticeable but not take up too much internal storage in the process. i have looked at 2.5 ssd's from Angelbird, and their pcie m.2 adapter. I have looked at various other very super duper fast pcie based options that cost a lot of money and it raised a big question. What really is slow? SSD latency is already at a speed where for all real purposes it is not noticeable so now I looked into read/write speeds. A 2.5 angelbird ssd at 564 MB/s read speeds. That means that it could read a 564 megabyte file in 1 second. Thats a pretty big file and that is pretty fast. I can't open my mouth that fast and I can talk fast. Now if you are doing huge video files then yes those files can get huge and be a lot of data. At 1 terabyte that would take about 30 minutes to be read at 564MB/s, if you had a 1000MB/s ssd then it would take 15 minutes. So I began to look into extremes at what I would have to be doing to have a single 1 terabyte file and wanting to read it with a ssd at 564MB/s. The answer was...... 1 terabyte of data would be equal to shooting a RED Weapon at 8k Full Format for 1 hour. So I think for now I will look into using the Sonnet Tech pcie card adapters that allow the mounting of 1 or 2 2.5 ssd drives. I can't see myself needing faster then that for a while. What have the rest of you found out while choosing ssd drives?
