" PS4 didn't have this problem... the DB player is fast than any mechanical HDD... so the devs will never use the HDD to cache the data before sent to RAM." No. Access time of an hdd is about 10ms, access time bd-player definitely over 100ms, some even 180ms. Transfer rate Bluray is 1x at 36Mbps.This is MBit - not Megabyte. So at 6x, we have 215 Mbit/s. This is even lower than USB 2.0 which has 480 MBit/s. A common hdd easily reads at 130 MByte/s. This is 1040 Mbit/s. But transfer speed is only one side of the medal because of access times (read: latency). The reason, for example, why ssds are "felt" stronger is not because of ther high transmit rate but because the access time is magnitudes better than hdds. This is why optical drives suck, and yes, this is also true for ps4-bdd. Every word of your conclusion is therefore also wrong. |
lol I make mistake with the BD speeds... so I'm wrong but about the HDD I'm right.
A common HDD is more like 50MB/s in sequencial read speeds (a 7200RPM one... the PS3 uses a 5400RPM).
If the PS3 had a 6x BD for read I can say to you the games will never use installation data (most don't use even with 2x BD).
