This high-end SSD drive has now encountered the capabilities of PCI Express 4.0, which delivers a transfer rate of approximately 8GB / s with four lines connected. The already completed PCIe 5.0 standard, which future generations of processors and motherboards already expect, but will double the display again to 16 GB / s theoretical. Marvel America Today AdvertiseIt produced the first controller that could handle the new interface at a faster speed.
However, we wouldn’t encounter the Bravera SC5 chip in the average consumer solid state drive, as it is primarily intended for storage for data centers. After all, PCIe 5.0 will be certified there as well as a priority.
The console provides a sequential read speed of 14 GB / s and a write speed of 9 GB / s. In terms of random reading, it comes to 1.8 million IOPS, and writing stopped at 1 million. Compared with previous generation, it provides up to 30% less response time and 40% higher efficiency.
Marvel has already designed two controllers. One of them will support eight channels’ access to NAND, and the other 16 channels. They can handle different chips from SLC to PLC and are designed for various SSD formats. For example, the manufacturer announces the transition from the M.2 connector to the new E1.S. On the other hand, it offers more storage power (up to 25W instead of 7W) and one of them supports the SSD plug-in at runtime.
New SSDs based on PCIe 5.0 are due to start rolling out widely next year. Marvell’s initial partners will include AMD, Intel and Renesas as creators of SSDs and server ecosystems Kioxia, SK Hynix and YMTC as manufacturers of NAND chips; And Facebook with Microsoft as the cloud operators.
