Ultra-fast SSD performance for the masses.

That design looks like they're made by Dedsec from Watch Dogs series.

Wonder how much DRAM they have as well as type of DRAM. Pretty important for performance.

What is annoying however is how WD are claiming its PS5 compatible and every news outlet is reporting it as such. Sony never said it would be approved. Why anyone(especially WD) would report it as approved is beyond me. Sony clearly said they were not going to whitelist any drives until after launch.

Samsung's 980 Pro isn't approved and is just as fast, they didn't just outright claim it was approved.

Well, they haven't produced a whitelist of good drives, but they have outlined the performance requirements:

(20:45 if timestamp breaks)


So if WD is confident that their drive is fast enough, the can claim compatibility.

He did not outline any requirements. He specifically said by year's end he expects drives to reach 7GB/s but that we are comparing apples to oranges. It comes back to the NVMe specifications of 2 priority levels vs the 6 PS5 has and the differences in architecture between the controllers.


They can claim compatibility. But what happens if Sony ends up saying actually no it's not fast enough? Lawsuits everywhere.

He did? Specifically that their drive has 5.5GBps of bandwidth but a more efficient scheduler for their use - so they expect some required overhead for emulating that on their own chip instead of utilising the drive's controller.


WD is confident that the drive has enough throughput for that overhead. And I doubt they're making that claim willy-nilly.

 

[NeverBackDown]

You basically just repeated what I said as to why it is apples to oranges. The point being he did not anywhere in the video state what the requirements are other than it it needs to be faster than our drive and needs testing to validate it. There is no way to validate WD claim as a consumer based off what he said. It is therefore out of turn for WD to speak without some kind of official Sony statement.

Those are his words. So whether or not you think anything faster than 5.5GB/s is enough is on you, his statement still stands, Sony will not be testing until likely after launch and "please hold off getting the m.2 drive until you hear from us". We did not hear from Sony.

I didn't say "anything faster than 5.5GBps". I said 5.5 and some overhead - this drive saturates PCI-E, manages 1M IOPS and uses TLC. If that won't meet their requirements, I guess we'll have to wait for terabyte class PCI-E 4.0 Optane drives from Intel. :lol:

I think it would be best for all big companies involved to wait and do thorough testing with said devices before anyone can claim anything.
