![]() Average workload power consumption and max consumption are two other aspects of power consumption, but performance-per-watt is more important. Some SSDs can consume watts of power at idle while better-suited ones sip just milliwatts. Idle power consumption is an important aspect to consider, especially if you're looking for a laptop upgrade as even the best ultrabooks can have mediocre storage. We use the Quarch HD Programmable Power Module to gain a deeper understanding of power characteristics. Our advice is that if an E18 drive seems too inexpensive to be true, it’s probably one that is best fit for console use. That could ostensibly include drives destined for lower-intensity work, like PS5 drives. Micron confirmed that the flash used on that drive, which we detected as having lower rated endurance, is completely legitimate and could find its way onto any number of drives. We will add that this type of performance result is not restricted to lesser-known brands like Netac, as we also had lower write performance with the 2TB Team A440 Pro. However, it does mean this drive needs to be a less expensive alternative to a drive like the FireCuda 530, for instance. This is pure speculation, but it will not impact performance too deeply, particularly on the PS5. This could lead to higher read latency, too. However, there can be performance issues when stress testing, particularly if you’re trying to ensure sufficient write endurance for warranty. After all, you’re not going to hit these endurance numbers with bad NAND. We have seen some performance inconsistencies like this before on drives that use lower-quality but still consumer-grade flash. In normal use, this won’t be a problem, but it does suggest Netac is doing something different, especially when considering the uneven results from other benchmarks. ![]() ![]() The precise speed is less important than the pattern of inconsistency that we see. Its cache is relatively conservative, similar to the other E18 drives on the chart, so its overall performance is lower than expected. The NV7000 writes at high speed in its pSLC mode before dropping down to a slower TLC mode, and then eventually struggles to an extremely slow state that brings down its steady state write performance.
