Oh, don't do so, ethomaz... don't pick the bad numbers from hdds to compare them to the optimum of bd-drives, that's not arguing.

Just look at this and remember the most current one is from 2010:

Every hdd you buy nowadays *easily* outperforms a bdd, especially because of access times. They are even way better in write-rates.

As I said, when in defense mode you are simply overdoing it at times. No offense but this isn't necessary.

I don't know the HDD have better read access today but I think that is because the more buffer cache... not the speed itself... in any case these read speeds not seems like standard HDD... the standard HDDs 7200rpm starte the read in ~90GB/s and drop to ~50GB/s after some seconds.

This beachmakr did't show the model of the HDD... I have a 7200rpm HDD in my PS3 that have 32MB SDD buffer cache... it is alway faster than any other 7200rpm HDD but because it have SDD parts for buffer cache.

The PS3 5400 HDD can't reach 50MB/s average read speeds.

I will find more benchs.


Feel free to find other benches.

But point for point:

Yes, there is buffer cache. But the pic shows they were transferring 4000MB of data. So caches don't help here. Don't know where you get the GB/s but that's obviously also wrong. Of course your hdd you use in your PS3 is a bit faster because of ssd-cache but that's not the point. And the ps3 has a crappy interface to hdd (meaning outdated) so that's no proof for anything.

No the benchmark didn't show the model but it's 3 years old. I am curious to see how you find someting proving the opposite (so that at any time the 6xbdd of ps4 is faster than an hdd).
