Specifications & Features

This PCIe 4.0 SSD boasts a fast controller and top-of-the-line flash, making it an excellent all-around performer. Plus, it's specifically designed to take advantage of Microsoft's upcoming DirectStorage API, which should bring significant performance improvements to gaming and production workloads. The Rocket 4 Plus-G is similar to the Sabrent Rocket 4 Plus, but with some key differences. The former uses the same 176-layer TLC flash as the latter, but with customized firmware optimized for gaming. This firmware is based on Phison's I/O+ firmware and is designed to deliver superior performance during DirectStorage gaming. While DirectStorage gaming is still a ways off, the Rocket 4 Plus-G is still an excellent choice for gamers who demand the very best performance from their hardware. The Sabrent Rocket 4 Plus-G is available in 1TB, 2TB, and 4TB versions, but unfortunately, there's no 8TB SKU. At the time of review, Sabrent had not released official performance specifications for this drive, but it should match or exceed the Rocket 4 Plus, which offers up to 7,200/6,850 MBps for sequential reads and writes, as well as up to 1 million random read/write IOPS.

Phison PS5018-E18 controller

The controller is a rehashed Phison E18, and that company is known for its flash NAND controllers and became very influential the past few years. The PS5018-E18 controller is based on a Cortex-R5 ×3, processor design and is manufactured at TSMC 12nm. By bringing this controller towards NVMe revision 1.4 the transfer rate per channel has increased from 800MT/s towards 1200 Increased to MT/s. And when you math that, that means a maximum transfer speed of roughly 7GB/s for both sequential reads and writes. Here's a nice value as well, random read/write performance would be listed at 1 million IOPS, and all that with an expected peak energy consumption of 3W for the controller alone
