data and an IR thermometer to see when (or if) thermal throttling kicks in and how it impacts performance. We also monitor the driveвЂ™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. We use the Quarch HD Programmable Power Module to gain a deeper understanding of power characteristics. For most workloads, the write performance should be sufficient and the cache will recover fairly quickly for responsive performance. It also recovered roughly 30GB of cache space within one minute of idle time. It lags most SSDs overall, but it is tuned for consumer burst-type workloads more than sustained writes anyway.

SamsungвЂ™s 980 Pro absorbed roughly 100GB of data before degrading from an average write speed of 2.5 GBps to an average rate of 315 MBps for the remainder of the test. We also monitor cache recovery via multiple idle rounds. We use iometer to hammer the SSD with sequential writes for 15 minutes to measure both the size of the write cache and performance after the cache is saturated. Sustained write speeds can suffer tremendously once the workload spills outside of the cache and into the 'native' TLC or QLC flash. Most SSDs implement a write cache, a fast area of (usually) pseudo-SLC programmed flash that absorbs incoming data. Official write specifications are only part of the performance picture.

Sustained Write Performance and Cache Recovery Even when scaling the QD up, the 980 delivers respectable peak random IOPS, too. With a read latency of just 0.059 milliseconds, it is one of the fastest random reading NVMe SSDs we have tested at a QD of 1. SamsungвЂ™s 980 achieved 3.2 / 2.3 GBps in peak sequential performance and achieved very respectable random speeds. Sequential read performance is not quite as fast as its DRAM-based competition, especially at 128KB-2MB block sizes, but its write performance is solid across all block sizes.
