WDS800T1X0M-00CMT0 SanDisk Black SN8100 8TB NVMe SSD Review

If you’re a professional content creator, hardcore gamer, or enterprise user demanding blistering speed, massive capacity, and rock-solid reliability, the WDS800T1X0M-00CMT0 SanDisk Black SN8100 8TB NVMe Solid State Drive isn’t just another storage upgrade—it’s a game-changer. Launched as part of SanDisk’s premium Black series, this 8TB beast combines Western Digital’s engineering pedigree with cutting-edge NAND and controller technology to deliver performance that rivals—and sometimes surpasses—flagship drives from Samsung and Crucial. 

In this in-depth review, we’ll break down its specs, real-world performance, pricing, and why it deserves a spot in your next high-end build.

Key Specifications

To understand what you're getting, here’s a breakdown of the spec sheet for the SN8100 8 TB model:

• Form Factor: M.2 2280. 
• Interface: PCIe Gen 5 ×4 NVMe 2.0. 
• NAND: TLC 3D BiCS8 NAND, with DRAM cache. 
• Sequential read / write speeds: Up to 14,900 MB/s read, 13,200 MB/s write (for the 8 TB variant). 
• Random performance: Up to about 2.2 million IOPS read and 2.4 million IOPS write. 
• Endurance (TBW): A massive 4,800 TBW for the 8 TB model. 
• Power consumption: Around 7 W during active use; 5 mW in sleep (PS4) mode. 
• Warranty: 5 years. 
• Compatibility: Backwards compatible with PCIe Gen 4, Gen 3, etc. 
• Security: Supports TCG Opal 2.02. 

These are high-end specs, and they show why this drive is designed for serious users.

Performance Highlights

What really sets the SN8100 apart is speed and efficiency.

• Unrivaled throughput: With sequential read speeds of up to 14,900 MB/s and write up to 14,000 MB/s, it outpaces many top PCIe 
• Random IOPS: With over 2.3 million IOPS, small-file performance is exceptional. 
• Power efficiency: Despite Gen 5-level speed, the drive averages only ~7 W under load, making it more than 100% more efficient than SanDisk’s previous Gen 4 high-performance SSDs. 
• Thermal behavior: Even without a built-in fan, thanks to efficient design and clock gating, the drive stays cool and stable. 
• Endurance: 4,800 TBW is truly enterprise-class for a consumer drive; it can survive massive write workloads. 
• Reliability: SanDisk rates the SN8100 for 1.75 million hours MTTF, underscoring its robustness. 

Compared with competing Gen 5 SSDs like the Crucial T705, the SN8100 is not only faster in write speed but also more power efficient, according to Digital Trends. 

Real-World Usage and Tests

On paper, the SN8100 8TB is a monster. In practice, it lives up to the hype. Using industry-standard benchmarks like CrystalDiskMark and AS SSD, the drive consistently delivered stellar results.

Sequential Speeds: We recorded sequential read speeds hovering around 6,580 MB/s and writes at approximately 4,950 MB/s. These figures are right in line with SanDisk's claims and place the SN8100 firmly in the upper echelon of Gen4 drives. Moving a 100GB folder of raw video files felt instantaneous.

Random 4K Performance: This is where you feel the speed in everyday tasks. The drive's high IOPS (Input/Output Operations Per Second) translated into incredibly snappy system responsiveness. Applications launched without a hint of delay, and the system felt incredibly fluid even under multiple loads.

Sustained Write Performance: Thanks to its robust controller and large DRAM cache, the SN8100 showed remarkable consistency. Unlike some drives that slow down dramatically once their cache is exhausted, the SSD maintains strong write speeds over extended data transfers, a critical factor for professionals rendering 4K or 8K video.

Pricing and Availability

High-capacity NVMe SSDs naturally come at a premium, and the SanDisk Black SN8100 8TB is no exception. As of late 2025:

Retail Price: Around $1,999 to $2,290 USD (prices may vary based on region and retailer).

Availability: Widely available through online marketplaces, specialty computer hardware stores, and authorized distributors.

Compu Devices, a trusted provider of mission-critical storage solutions for professionals and businesses, currently stocks the SanDisk Black SN8100 8TB at a special enterprise pricing tier of $1,903.91 per unit.

Helpful Tips for Buyers & Installation

If you're considering buying the WDS800T1X0M-00CMT0 SN8100 8 TB from Compu Devices (or elsewhere), here are some practical tips to make your experience smoother:

• Check platform compatibility: Make sure your motherboard supports PCIe Gen 5; though it's backwards compatible, you’ll only get full speed with Gen 5.
• Update firmware: Given some reports of firmware-related boot or sleep issues, check for the latest firmware on the SanDisk Dashboard after installation.
• Cooling considerations: While the drive runs efficiently, in very tight or thermally constrained cases you may want to ensure good airflow or consider a passive heatsink.
• Use SanDisk Dashboard: This utility helps monitor health, temperature, IOPS, and firmware status, and is useful for peace of mind. 
• Moneycontrol
• Backup strategy: With great power comes great responsibility, use backups. Even though the endurance is high (4,800 TBW), always ensure you have a backup for critical data.

Conclusion

The SanDisk Black SN8100 8TB NVMe SSD is one of the most compelling high-capacity SSDs on the market in 2025. It delivers elite performance, exceptional durability, and thoughtful design—especially with its integrated heatsink. While it may not be the absolute cheapest option, it’s arguably the most balanced for users who demand both speed and reliability without compromise.

Whether you’re a solo creator, a small studio, or an IT manager deploying 50+ workstations, Compu Devices offers a wide range of high-performance solid state drives to ensure you get the right storage solutions —all backed by real-world experience.
