Enterprise SSD with 480 GB capacity, PCIe 4.0 x4 interface, up to 7000 MB/s read and 800 MB/s write speeds, 0.4 DWPD endurance and 350 TBW rating
Capacity 480GB
This Kingston SEDC2000BM8/480G is a 480GB M.2 2280 drive built for data-centre workloads. It connects through a PCIe 4.0 x4 interface using the NVMe protocol. The 3D TLC memory delivers up to 7000 MBps sequential read and 800 MBps sequential write speeds. Random performance reaches 530,000 read IOPS and 32,000 write IOPS.
Active power draw averages 3.22 W during reads and 5.60 W during writes, peaking at 3.29 W and 5.77 W respectively. The drive operates from 0 °C to 70 °C and survives storage between -40 °C and 85 °C. Vibration resistance is rated at 20 G peak across 10–2000 Hz. No moving parts mean silent operation in normal use.
The drive is warranted for 0.4 drive writes per day, equivalent to 350 TB total bytes written. MTBF is rated at 2,000,000 hours. Buyers who need higher write endurance or larger capacities should consider other models. The 8.3 mm height fits standard M.2 slots.
Measured against everything we stock in Server & Data Center SSDs, at today’s prices. Recalculated every night.

Other versions of this model
Insert the M.2 2280 module into the PCIe 4.0 x4 slot at a 30-degree angle, then secure it with the retention screw; the step often missed is confirming the motherboard key matches the M-key notch on the drive.
The drive has no moving parts, so routine maintenance is not required; replacement is driven by the 350 TBW endurance rating or the 0.4 DWPD limit reached over its service life.
Sustained sequential write speed is rated up to 800 MBps, and the 0.4 DWPD endurance budget will be consumed before thermal throttling becomes the primary constraint.
