- Despite the SN5000's edge, the SN7100 maintains competitive performance, especially in multitasking contexts.
CrystalDiskMark Sequential Read/Write Performance
In this test, the SN7100 excels at higher queue depths, showing its capability for sustained data transfers.
- At QD8, the SN7100 significantly outpaces the SN5000 in both read and write speeds.
- Even in single-queue depth, the SN7100 demonstrates superior write capabilities.
CrystalDiskMark Random Read/Write Performance
Here, we evaluate the performance using small data blocks, simulating everyday usage scenarios.
- The SN7100 outshines the SN5000 in random read/write tests, particularly in high-queue scenarios.
- This makes the SN7100 a better option for tasks requiring heavy multitasking.
File Transfer Rate
In file transfer tasks, the SN7100 consistently outperforms the SN5000, especially when dealing with large files.
- Its ability to read compressed files faster indicates stronger sustained performance.
- The SN5000, while reliable, does not match the speed of the SN7100 for frequent file transfers.
Power consumption and efficiency
Efficiency is crucial for long-term use, especially in portable systems. The SN5000 demonstrates a higher throughput per watt, making it the more efficient option overall.
- It features a slightly lower idle power draw, which may appeal to energy-conscious users.
- The SN7100, while competitive, consumes more power at idle but excels during peak usage.
Durability metrics: TBW, DWPD, MTBF, and warranty
Durability is a key factor when selecting an SSD. The SN7100 offers a higher Total Bytes Written (TBW) rating for its 2TB and 4TB variants, while the 500GB and 1TB versions share the same TBW rating. It's important to note:
- The Drive Writes Per Day (DWPD) rating remains consistent at 0.3 for all versions, except for the 2TB and 4TB SN5000, which have a DWPD of 0.2.
- These metrics are critical for users who plan to put their SSDs through heavy data-writing tasks.
Technical specifications overview
The technical specifications further highlight the differences between the two models:
- The SN7100 benefits from higher raw NAND speed, which translates into better performance in demanding applications.
- While both models have a Pseudo-SLC write cache, the SN7100 features a dynamic cache of around 650GB for its 4TB variant.
- Notably, the SN7100 lacks encryption, which can be a concern for users prioritizing data security.
Price comparison
Price can be a decisive factor when selecting an SSD. The differences in cost between the SN5000 and SN7100 are minimal for the 500GB and 1TB variants:
- The SN7100 is typically $1 to $2 more expensive for these lower-capacity variants.
- As capacities increase, the price difference becomes more pronounced. For instance, the 2TB SN5000 retails at approximately $124.99, while the SN7100 is available for $149.99, a $25 difference.
- It's advisable to check various retailers to ensure you get the best deal.
Additional considerations for choosing your SSD
When deciding between the WD Blue SN5000 and WD Black SN7100, consider additional factors that may influence your choice:
- Use Case: Identify whether you need the SSD for casual usage, gaming, or professional work.
