Western Digital WD Black SN8100 1TB

Name: Western Digital WD Black SN8100 1TB
Brand: Western Digital
SKU: 11900

Manufacturer: Western Digital

The Western Digital WD Black SN8100 1TB is a high-capacity M.2 NVMe solid-state drive built around the PCIe 5.0 interface, positioning it among the more recent generations of consumer and prosumer storage solutions. It uses TLC NAND storage and includes a DRAM cache, which helps maintain consistent performance during sustained workloads. The drive ships without an integrated heatsink or RGB lighting, keeping the design straightforward for users who prioritize function over aesthetics.

On the technical side, the SN8100 1TB is powered by the Silicon Motion SM2508 controller, which operates across 8 channels and supports NVMe version 2. Sequential read performance reaches up to 14,900 MB/s, while sequential writes top out at 11,000 MB/s. Random performance is rated at 1,600,000 read IOPS and 2,400,000 write IOPS. The drive carries a PassMark SSD score of 79,571, a 600 TBW endurance rating, an MTBF of 1.8 million hours, and comes backed by a 5-year warranty.

Pros

Sequential read speed of 14,900 MB/s and sequential write speed of 11,000 MB/s indicate strong throughput for large file operations
Random write performance rated at 2,400,000 IOPS supports demanding workloads involving frequent small write operations
PCIe 5.0 interface and NVMe version 2 represent current-generation connectivity standards
DRAM cache helps maintain stable performance during sustained data transfers
600 TBW endurance rating combined with an MTBF of 1.8 million hours reflects solid long-term reliability
Five-year warranty provides extended coverage for the drive

Cons

No integrated heatsink, which may require users to source thermal management solutions separately when operating in heat-sensitive environments
TLC NAND, while common, offers lower write endurance per cell compared to SLC or MLC alternatives
The M.2 form factor requires a compatible motherboard slot supporting PCIe 5.0 to fully utilise the drive's rated speeds

Who is this for?

This drive is well-suited to users who need high sustained throughput for large file operations, such as video editors, 3D rendering workflows, or anyone regularly moving substantial amounts of data. The PCIe 5.0 interface and NVMe 2.0 support mean it is also a strong fit for those building or upgrading systems on current-generation platforms that can take full advantage of the available bandwidth. With a 600 TBW endurance rating and a five-year warranty, it also suits users who prioritize long-term reliability in workstation or prosumer environments where the drive will see consistent, demanding use.

Who is this NOT for?

Users with motherboards that only support PCIe 4.0 or older will not be able to access the drive's full rated speeds, making it a poor match for older or budget system builds where the interface would act as a bottleneck. Since the drive ships without an integrated heatsink, it may also be less appropriate for compact or thermally constrained builds, such as small form factor cases, where sustained workloads could lead to thermal throttling without additional cooling provisions. Casual users with light storage demands would also find little practical benefit from the drive's high-end specifications.

Read speed:

sequential read speed	14900 MB/s
random read speed	1600000 IOPS

The WD Black SN8100 1TB delivers a sequential read speed of 14,900 MB/s, making it well-suited for large file transfers and data-intensive tasks that benefit from high sustained throughput. On the random side, it reaches 1,600,000 read IOPS, which reflects strong performance when handling the smaller, non-contiguous read operations typical of everyday system workloads and application loading.

Write speed:

sequential write speed	11000 MB/s
random write speed	2400000 IOPS

The WD Black SN8100 1TB is rated for a sequential write speed of 11,000 MB/s, supporting fast sustained data writes across large files and bulk transfers. Its random write performance is specified at 2,400,000 IOPS, indicating strong handling of fragmented write operations commonly encountered during multitasking and active system use.

Benchmarks:

PassMark result	79571

In the PassMark benchmark, the WD Black SN8100 1TB achieves a PassMark SSD score of 79,571, providing a standardized reference point for evaluating its overall storage performance across the range of read, write, and latency tests that the PassMark suite covers.
