Gen3 vs Gen5 Speed Comparison
Transfer Speeds
The XPG Mars 980 Blade offers significantly higher sequential speeds than the SX8100. The Mars 980 Blade reaches up to 14,000 MB/s read and 12,000 MB/s write. This uses the newer PCIe 5.0 interface. The SX8100 maxes out at 3,500 MB/s read and 3,000 MB/s write on PCIe Gen3. For large file transfers or heavy video editing, the Mars 980 Blade moves data much faster. The SX8100 is adequate for general tasks but lags in raw throughput. You will notice the difference in sustained write performance during large operations.
Interface Generation
The Mars 980 Blade uses the latest PCIe 5.0 x4 interface with NVMe 2.0 support. This provides a wider bandwidth lane for data transfer. The SX8100 relies on the older PCIe Gen3 x4 interface. While Gen3 is still functional, it is a previous generation technology. The newer interface on the Mars 980 Blade ensures better future-proofing for compatible motherboards. If your system supports PCIe 5.0, the Mars 980 Blade can utilize its full potential. The SX8100 will run at its maximum Gen3 speeds regardless of motherboard capability.
Cache Type
The Mars 980 Blade includes onboard DRAM cache. This component helps maintain consistent speeds during heavy data loads and improves system responsiveness. The SX8100 data does not specify a DRAM cache type. Without explicit data on its cache, we cannot confirm it has one. DRAM cache is beneficial for sustained performance and reducing latency. The Mars 980 Blade likely handles intensive workloads more efficiently due to this feature. The SX8100 may experience speed drops under heavy sustained writes.
Storage Capacity
The SX8100 comes in a 512GB capacity. The Mars 980 Blade is available in 1TB, 2TB, and 4TB sizes. The 1TB model offers double the storage of the SX8100. This allows you to store more games, videos, and projects. The SX8100 is limited to half that space. If you need more room for large files, the Mars 980 Blade provides better value in capacity. The SX8100 is suitable only if your storage needs are modest.
NAND Type
The SX8100 explicitly uses 3D NAND technology. The Mars 980 Blade data does not specify the NAND type. Both drives use NAND flash for storage. The SX8100’s use of 3D NAND is a known architecture for density. Without specific data on the Mars 980 Blade’s NAND, we cannot compare the cell technology directly. We can only note that the SX8100 confirms its use of 3D NAND. The Mars 980 Blade may use a different or newer NAND variant, but this is not stated in the provided specifications.
