ONEBOOM X400 4TB internal SSD

The ONEBOOM X400 2280 is a 4TB internal solid-state drive built for consumer PCs and PlayStation 5 storage expansion. It uses the M.2 2280 form factor and connects through a PCI-Express 4.0 x4 interface with NVMe 1.4 protocol. Sequential reads reach up to 7400 MBps and writes up to 6500 MBps.

3D TLC NAND and NVMe 1.4 controller

The drive employs 3D TLC memory components paired with an NVMe 1.4 controller to deliver up to 650000 random read IOPS and 670000 random write IOPS. Endurance is rated at 2400 TBW with a 1000000-hour MTBF. Power draw measures 0.73W idle and 4.56W active, and the unit ships without a heatsink.

PCIe 4.0 x4 bandwidth ceiling

The PCIe 4.0 x4 link provides double the raw bandwidth of a PCIe 3.0 x4 connection, capping theoretical throughput at the interface limit. Real-world speeds depend on host controller implementation, thermal conditions, and workload mix. The drive meets Sony's PS5 speed requirements for internal expansion.

Questions about this item

How long will the 2400 TBW rating last before the drive needs replacement?

The 2400 TBW endurance rating means you can write 2.4 petabytes of data over the drive's lifetime. For typical gaming and creative workloads writing 50-100 GB per day, this provides several years of service before reaching the warranty limit.

What performance limit appears first during sustained heavy writes?

The sequential write speed reaches up to 6500 MB/s, but sustained workloads will eventually hit the 670,000 IOPS random write ceiling or thermal throttling since the drive ships without a heatsink.

What are the power draw and heat levels when the SSD runs all day?

Active power consumption is 4.56 W and idle power is 0.73 W. Without a built-in heatsink, the controller relies on motherboard airflow; expect higher temperatures during continuous PCIe 4.0 x4 transfers.
