Crucial T705 PCIe 5.0 SSD parameters exposed

In May of the preceding year, Crucial’s T700 PCIe 5.0 SSD, lauded as the “world’s fastest PCIe 5.0 NVMe SSD” at the time, made its debut. It featured Phison’s E26 controller chip and Micron’s 232-layer TLC NAND flash, achieving impressive continuous read/write speeds of 12400MB/s and 11800MB/s, respectively.

With the ongoing evolution of PCIe 5.0 SSD technology, recent leaks have hinted at Crucial’s forthcoming T705 PCIe 5.0 SSD, which promises even greater speeds, reaching up to 14500MB/s read and 12700MB/s write, with random read/write speeds also impressive at 1550K IOPS and 1800K IOPS. It will be available in 1TB, 2TB, and 4TB storage capacities.

The T705 will utilize the same 232-layer TLC NAND flash from Micron and will include a dedicated cache, though its specifications and the controller chip remain undisclosed. Rumors suggest it might use an enhanced version of the Phison E26, dubbed E26 Max14um. This new controller, showcased at CES 2024 in January, optimizes firmware for reduced power consumption and increased speed but requires active cooling, rendering it unsuitable for laptop use.

The E26 Max14um controller boasts a dual Arm Cortex-R5 core processor, up to eight channels; supports TLC and QLC NAND flash with an interface rate of 2400 MT/s; and achieves top speeds exceeding 14,000MB/s read and 12,000MB/s write, with random read/write speeds of 1,500K IOPS and 2,000K IOPS, respectively. It supports DDR4 and LPDDR4 cache, along with AES256, SHA512, RSA-4096, and TCG OPAL hardware encryption.

Further leaks reveal that the T705 PCIe 5.0 SSD will offer a version with a heat spreader and a limited edition in white thermal coating.
