![]() Reference:, I reviewed the WD long before the KC3000 ever existed. Most of the other reviewers don’t include data, let alone IR data to verify the S.M.A.R.T data. KC3000's 70 deg-C? During gaming, is the efficiency high enough to keep the temps down so the SN850 won't see the 92degsC during gaming? I appreciate the temperature information in your reviews. ![]() Your SN850 review stated that it runs to a peak of 92 deg-C vs. In reference to high temps, for my understanding and comparison uses, please explain why you pick the WD SN850 as a laptop upgrade over the Kingston KC3000 when based on your SN850 review. Plk2 said:Sean, would you explain your statement "If you are looking to upgrade your lightweight laptop, consider the Samsung 980 Pro or WD Black SN850, both of which are more power-efficient.". Again, remember that results will vary based on the workload and ambient air temperature. data and an IR thermometer to see when (or if) thermal throttling kicks in and how it impacts performance. We also monitor the drive’s temperature via the S.M.A.R.T. A drive might consume more power during any given workload, but accomplishing a task faster allows the drive to drop into an idle state more quickly, ultimately saving energy. 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. Unfortunately, the KC3000 did not recover any of its SLC cache during the idle recovery rounds, but its write speed measured roughly 1.9 GBps instead of 1 GBps. Our 1TB KC3000 sample absorbed 369GB of data at a rate of 6,050 MBps before degrading to roughly 1,015 MBps for the remainder of the test. With such a large and fully dynamic SLC cache, the KC3000 gives end-users a lot of space for writing at full speed, but this inevitably also results in slower write performance once it saturates the cache with incoming write data. During extended tests, Kingston’s KC3000 delivers solid sequential write performance but can’t keep up with the WD Black SN850 and Samsung 980 Pro.
