Lexar hits 7 GB/s with new M.2 PCIe 4.0 SDD

Lexar hits 7 GB/s with new M.2 PCIe 4.0 SDD

The read and write speed of SSDs are exceeding far beyond what we need in real life. Recently you've already seen M.2 SSDs perform at the 4GB/s and 5GB/s marker, well, no you may add to that Lexar, who showed an example running with read performance of 7 GB/sec.

Lexar has been demoing several new memory products at an event in China, however, the SSD performance was something new to observe. Based on pcie 4.0 interface x4 connector and measured with IOMeter it scored 7 GB per second in reading tasks. Lexar mentions that will be the final speed of the product. A CrystalDiskMark screenshot showed a sequential read score of 6,224 MB/s with Sequential writes at 4,246.4 MB per second. 

The SSD will be available in 512 GB, 1 TB, and 2 TB formats and makes use of 96-layer TLC-NAND chips, likely from Toshiba Memory, named Kioxia these days. As of yet market availability, pricing and controller brand is not yet known.

That is very interesting.... I wonder what controller it uses, because Phison E16 can only do 5 R 4.4 W

Only 54MB/s @ 4k random read @ QD=1.

Even the old samsung 950pro is faster

That would be Silicon Moton SM2264 - that's currently the only PCIe 4.0 capable alternative to Phison PS5018-E18.

SM2264 is rated for 6.5/3.9 GB/s sequential read/write and 700K IOPS.

I am not asking to be a smart alack, but in the article you say the speed is faster than what we need in real life. What speed do we need?

Was coming here to say the same thing. If they could pull off even 100MB/s on 4KQ1T1 this would be a pretty cool advancement.
