8TB capacity for gaming and workstations

This 8TB internal SSD uses the M.2 2280 form factor with a PCIe 4.0 x4 NVMe interface. It targets gamers and workstation users who need fast load times and space for large libraries. The drive delivers up to 7300 MBps sequential read and 6600 MBps sequential write speeds.

Upgrade from SATA or PCIe 3.0 drives

The jump is worth it when games exceed 850GB installs or when content creation projects demand sustained throughput. Sequential reads reach 7200 MBps and writes reach 6600 MBps, while random IOPS hit 1200000 for both read and write. An 8GB DRAM cache helps maintain consistent performance under heavy workloads.

8TB headroom with 4800 TBW endurance

The capacity comfortably holds dozens of modern titles and large project files without frequent cleanup. Endurance is rated at 4800 TBW with an MTTF of 1.75M hours. Operating temperatures range from 0°C to 85°C, and the drive tolerates shock up to 1500G. Active power averages 130mW with a maximum of 8W.

Questions about this item

Will the M.2 2280 form factor fit my motherboard slot?

The drive uses the M.2 2280 form factor, which measures 22 mm wide by 80 mm long. Most modern desktop and laptop motherboards with an M.2 key-M slot accept this size.

What is the correct way to install the NVMe SSD and which step is often missed?

Insert the drive at a 30-degree angle into the PCIe 4.0 x4 slot, press down, and secure it with the motherboard standoff screw. The step many miss is fastening that screw, which keeps the drive firmly seated.

When should I expect to replace the drive based on its endurance rating?

The drive is rated for 4800 TBW and an MTTF of 1.75M hours. Under typical gaming or workstation workloads this translates to many years of service before the NAND reaches its write endurance limit.
