Preface

At the beginning of September Sabrent showed the Rocket 4 Plus. It is the successor to the manufacturer’s first pcie 4.0 ssd, which was released a month earlier. Thanks to the new PS 5018 – E 18 – controller from Phison, the SSD is able to achieve sequential read and write speeds of 7 and 6 respectively, 85 GB / s. Both the random reads and writes amount to a maximum of 1 million iops. The PS 5018 – E 18 supports SSDs in m.2 format, with a capacity of 512 GB to 4 TB. The controller is made on TSMCs 12 nm -node.

According to TweakTown, the controller has even more to offer. The emerged CrystalDiskMark result would have been achieved with the E 18 – controller, although it is not known in which SSD it is used. The drive achieves sequential read speeds of nearly 7.4 GB / s, and sequential write speeds also exceed 7 GB / s.

Update, 24 October – Phison has told Tom’s Hardware that the E 18 in the manufacturer’s test labs, has achieved more than 1.2 million Iops in Iometer. We do not have many characteristics of the SSD used and we do not know which hardware the test system has, but it is known that the SSD is an engineering sample of 2 TB and uses Micron’s B 27 B-Flash Memory with 96 layers, three bits per cell (tlc) and a capacity of 512 gigabit per chip.
