Realtek joins Silicon Motion and Phison in the PCIe Gen5 SSD controller club

With its brand new RTS5782 controller announced during Computex 2024, Realtek joins Phison and Silicon Motion in the very exclusive club of manufacturers of consumer PCIe Gen5 SSD controllers. It is an 8-channel NVMe 2.0 controller supporting 3600MT/s NAND and has a dedicated DRAM cache in DDR4/LPDDR3/LPDDR4/LPDDR4x. It is announced at 14GB/s sequential read and 12GB/s write with 2500k IOPS random read/write.

If the availability date of the Realtek RTS5782 controller has not yet been officially announced, we do however know that it will be the spearhead of a range of controllers including 4 other references as follows:

• The RTS5781DL: an RTS5782 with only 4 channels and no DRAM cache
• The RTS5776DL: an RTS5781DL in PCIe-Gen4
• The RTS5772DL: an NVMe 1.4 controller in PCIe-Gen4 with 8 channels supporting 1600MT/s NAND without DRAM cache
• The RTS5766DL: an RTS5772DL in PCIe-Gen3 with only 4 channels

If the interest of the last one on the list, the RTS5766DL, can leave you perplexed (PCIe Gen3 in 2024?!?), this very complete range at least has the merit of highlighting Realtek’s desire to impose itself on a market from which he was until now notably absent.
