It's been about a year since the PCIe 5.0 SSDs hit the market. However, up until now, most products have hovered around speeds of roughly 12GB/s for maximum read/write, with only a few enterprise-level options exceeding 14GB/s.
But the Intel T705 2TB SSD we're testing today has shattered expectations, boasting a maximum read speed of 14500MB/s. This achievement stands as the pinnacle of performance for PCIe 5.0x4 SSDs.
Let's take a look at how the Intelis T705 2TB SSD achieves this!
Overclocked Phison PS5026-E26 Controller: The Phison PS5026-E26 is an eight-channel controller with 2 ARM Cortex-R5 cores and 3 dedicated IP cores. It supports DDR4/LPDDR4 cache and has a maximum read speed of 12GB/s and a maximum write speed of 11GB/s. The Intelis T705 2TB SSD undergoes overclocking of this controller, effectively lifting the performance restrictions. Paired with Micron's 2400MT/s 3D TLC NAND, this SSD achieves impressive read speeds of up to 14500MB/s and write speeds of 12700MB/s, surpassing all PCIe 5.0 SSD products we've tested with the same controller.
11% SLC Cache Strategy: The Intelis T705 2TB SSD employs an SLC cache with 11% capacity and boasts fast cache clearing speeds. This ensures that even when writing data equal to 37% of the total disk capacity in one go, it maintains the highest write speeds. Furthermore, its off-cache speed is also excellent, guaranteeing sustained write speeds of over 1GB/s even when the available space is very small.
