A minimum of three SSD makers — Corsair, Gigabyte, and Goodram — introduced their SSDs primarily based on Phison’s E26 controller with a PCIe 5.0 x4 interface over the previous few weeks. Corsair’s and Goodram’s drives provide a most sequential learn velocity of 10 GBps, whereas Gigabyte’s product is claimed to hit 12.4 GBps. There’s a motive for that: No 3D NAND chips are presently quick sufficient to saturate the controller’s capabilities.
Phison’s PS5026-E26 controller has eight NAND channels, which is typical for consumer SSDs. These channels assist totally different knowledge switch charges, however to saturate a PCIe 5.0 x4 (15.754 GBps in each instructions), it wants 3D NAND reminiscence with a 2400 MTps interface. Micron was first to announce such reminiscence this July, SK Hynix adopted in early August, then YMTC launched its Xtacking 3.0 structure enabling a 2400 MTps velocity. All of Phison’s E26 demonstrations have been with SSDs that includes Micron’s newest 3D NAND chips, and that is when these drives hit ~12 GBps sequential learn speeds. Galax can be testing its HOF Excessive 50 SSDs with Micron’s 232-layer 2400 MTps chips, in accordance with ITHome (opens in new tab).
