What this drive is and who it serves

The Crucial T705 CT4000T705SSD5 is a 4TB internal SSD built for consumer workloads that demand Gen5 throughput. It targets gamers and creators moving large game libraries, UHD video projects or heavy multi-tasking datasets onto a single high-capacity stick.

The spec that decides fit

The drive connects through a PCI-Express 5.0 x4 interface and delivers up to 14,100 MBps sequential read and 12,600 MBps sequential write with 1,500,000 IOPS random read and 1,800,000 IOPS random write. Your motherboard must expose a Gen5 M.2 slot to reach these figures; a Gen4 slot will cap the transfer rates.

Installation and common pitfalls

The module uses the M.2 2280 form factor and ships with an integrated aluminum-and-copper heatsink that must stay attached for thermal control. Ensure the motherboard standoff is set for 2280 length and that case airflow passes over the heatsink; restricted airflow is the typical cause of throttling.

Questions about this item

Will the integrated heatsink fit under my motherboard's M.2 shield?

The drive uses the standard M.2 2280 form factor with an aluminium and copper heatsink attached. Measure the clearance between your motherboard's M.2 slot and any cover or shield; the heatsink adds height above the bare PCB.

Does my platform support the stated PCIe 5.0 speeds?

Full PCIe 5.0 x4 throughput requires a CPU and chipset with Gen5 support, such as Intel Core 13 or 14 series or AMD Ryzen 7000 series. Older platforms will limit the drive to Gen4 or Gen3 speeds.

Is the 4 TB capacity usable for large game libraries and video projects?

Yes, the 4000 GB TLC NAND drive delivers up to 14,100 MB/s sequential read and 12,600 MB/s write, with 1,500,000 random read and 1,800,000 random write IOPS, so large AAA titles and UHD or 8K+ footage load and scrub quickly.
