INTRODUCTION

    PCIe 5.0 Gen5 M.2 NVMe solid state drives (SSDs) may not be quite free of their thermal issues but new firmware upgrades and even controllers have certainly helped with that and well, these along with a now significant number of PCIe 5.0 compatible motherboards are the reason as to why Gen5 SSD sales have finally taken a turn for the better. Granted, there's still a somewhat limited number of available Gen5 SSDs in the market but more will be making their appearance before long, with a few surprises I might add. For now, probably the most popular Gen5 SSD line is no other than the T705 one by Crucial and since quite a few asked today I'll be testing the 4TB capacity model.

    Once again, the T705 line of PCIe 5.0 Gen5 M.2 NVMe SSDs by Crucial is currently available either with or without a black or white (limited edition) aluminum and nickel plated copper heatsink and in 3 different capacities (1/2/4TB).  The T705 uses the client-grade PS5026 (E26) PCIe 5.0 Gen5x4 NAND flash controller by PHISON along with Micron's 232-layer 3D TLC NAND flash (B58R 2400MT/s) and LPDDR4 DRAM (1GB per TB of NAND flash). This combination allows the 1TB variant of the T705 to surpass 13GB/s in reads (10GB/s in writes) and the 2/4TB variants to surpass 14GB/s in reads (12GB/s in writes). Once again, the 8-channel (32 CEs) dual-CPU (ARM Cortex-R5) E26 NAND flash controller by PHISON is NVMe v2.0 compliant, features Pison’s 5th generation LDPC ECC & RAID ECC together with SmartECC (RAID ECC), End-To-End Data Path Protection, TRIM and AES 256-bit encryption (with SHA 512 and RSA 4096) and supports Toggle 5.0, ONFi 5.0 and TCG Opal 2.0. Crucial typically covers the entire T705 line of Gen5 SSDs with a 5-year limited warranty and reports a TBW (Terra Bytes Written) of 600 for the 1TB model, 1200 for the 2TB model and 2400 for the 4TB model.
