4TB PCIe 5.0 NVMe drive for high-end workloads

The Crucial T700 CT4000T700SSD3 is a 4TB internal SSD built on the M.2 2280 form factor. It uses Micron 232-layer TLC NAND and the NVMe 2.0 protocol over a PCI-Express 5.0 x4 interface. The drive targets consumers who need maximum throughput for gaming, content creation and heavy multitasking on Intel 13th Gen or AMD Ryzen 7000 platforms.

PCIe 5.0 x4 bandwidth and thermal limits

The PCI-Express 5.0 x4 link delivers up to 12,400 MBps sequential read and 11,800 MBps sequential write, with 1,500,000 IOPS for 4KB random read and write. Sustained speeds at this level generate significant heat, so the drive must be used with a motherboard heatsink and adequate airflow to avoid throttling. Without that cooling, real-world performance will drop below the rated peaks.

Direct M.2 installation with mandatory heatsink

Installation is a standard M.2 slot insertion, but the T700 cannot run without a heatsink attached. Most issues arise when the motherboard heatsink is missing, poorly seated or blocked by other components, causing thermal throttling. Verify that your board provides a compatible heatsink and clear airflow before fitting the drive.

Questions about this item

Should I choose the 4TB version or a smaller capacity?

The 4TB model stores more games, UHD or 8K media and heavy workloads in one drive, avoiding the need to juggle multiple volumes.

What does the 12,400 MBps sequential read mean for actual game loads?

With Microsoft DirectStorage the drive can deliver up to 60% faster texture renders and noticeably shorter load times in supported titles.

Will PCI-Express 5.0 x4 be limited by my motherboard?

The drive runs at PCI-Express 5.0 x4 speeds on Intel 13th Gen and AMD Ryzen 7000 platforms; older chipsets will negotiate a lower link speed.
