Many data storage devices manufactures have announced their PCIe 4.0 SSDs which are using Phison PS5016-E16 controller.
These SSDs have much faster read speed.
Of course, this will lead to faster SSDs.
However, the fact is that you see nothing now.
When it will come?
Phison says SSDs speed will reach up to 6.5GB/s next year.
Perhaps, you dont pay attention to these things.
On a technical level, it has already been usurped by PCIe 5.0 that was only recently ratified.
However, it will still take several years before we see the actual products which are using PCIe 5.0.
How about PCIe 4.0?
Indeed, the same is not true of PCIe 4.0.
The same point is that all of these SSDa are using a Phison PS5016-E16 controller.
Essencore 2 TB PCIe 4.0 SSD enters the game in COMPUTEX Taipei.
These new drives sequential read speeds can reach up to 5GB/s in theory.
you better know that the read performance of the best NVMe SSDs is just about 3.5GB/s.
The speed advantage of PCIe 4.0 SSD is obvious.
A video on YouTube from Mixed Skills shows that the Phison CEO K.S.
On the technical side, the PCIe 4.0 controller supports about 2GB/s per lane.
That is to say, in a x4 configuration, the bandwidth ceiling can sit at 8GB/s or so.
Of course, you should know that it is the theoretical limit and doesnt account for overhead.
Moreover, there is still headroom to venture into the kind of territory that Phison is promising.
However, if you want to transfer numerous large files, these faster SSDs can speed things up.
Also it is important that a faster SSD can help drive down the price of current models.
For SSD market, it will still take some time to apply the new controller in it.
