I would like to know where you found out that the hdd stored the 15 minute video stream. I think that its technically weird why they would use it for that as it would adversely and substantially affect the performance of games, which rely on the hdd exclusively for its data. A 1 megabyte per second stream to RAM is peanuts and it is much, much better at dealing with multiple tasks. |
Think of it, RAM is very expensive memory and the PS4 only has 8GB of it. its got a 500GB HDD.
As you said, a 1Mb/s stream to RAM is peanuts. But its also peanuts to the HDD. now let's assume that its even more than 1MB/s, say its 2MB/s, that basically translates to 2MB/s write (to ram or HDD). The HDD is capable of at least 200MB/s bandwidth. Now if the majority of the bandwidth is used up for read tasks (reading game data to system ram) there will still be at least 20MB of bandwidth left for write tasks.
Using the system RAM for game DVR is just a waste of reseourfes, cause a 15min stream at 2MB/s comes up to a whopping 1.8GB. that's a ridiculous waste of system ram when they could just as easily store that to the HDD in the non user accessed part of the HDD anyways.
