![]() We also monitor the temperature of the drive 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 faster, which ultimately saves power. 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. So, instead of immediately recovering, it may take a few hours of idle time to refresh fully. As a result, the 980 Pro trails its predecessor when hammered with writes over long periods.Īfter half an hour of idle time, Samsung's 980 Pro only recovered 6GB of the TurboWrite cache. Overall, this gives the 980 Pro very strong initial write performance for most applications, but it has slower direct-to-TLC write performance than the 970 Pro’s steady 2.7 GBps of performance. After we filled the cache completely, performance increased to an average of 2.2 GBps. Once it began writing directly to the TLC flash, average performance measured 1.8GBps until full. Samsung’s 1TB 980 Pro wrote at a rate of 5.2 GBps for roughly 120GB before the TurboWrite SLC cache filled. 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, which is 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 In terms of raw IOPS capability, Team Group’s Cardea Ceramic C440 has the upper hand and overtakes the 980 Pro by a few thousand IOPS at high QDs. The drive delivers roughly 22,000 IOPS, responding within 0.46 ms (on average) to 4K random requests at QD1, Proving even more responsive than either Adata’s XPG SX8200 Pro or the SK hynix Gold P31. But Samsung’s 980 Pro has taken big strides forward. When it comes to random performance, Intel’s Optane SSD 905P makes it clear that it won’t be beaten at low QDs. The 980 Pro’s peak sequential performance measured 7,138/5,272 MBps read/write, easily exceeding the 7/5 GBps rating. The 980 Pro overshadowed the Phison E16 based Team Group Cardea C440 and all other competitors. We tested Samsung’s 980 Pro at a QD (queue depth) of 1, representing most day-to-day file access at various block sizes. Game Scene Loading - Final Fantasy XIVįinal Fantasy XIV Stormbringer is a free real-world game benchmark that easily and accurately compares game load times without the inaccuracy of using a stopwatch. For good measure, we threw in Intel’s Optane SSD 905P to define the upper limits of pricey performance. Of course, we couldn’t forget about Adata’s XPG SX8200 Pro, one of the all-around best values, nor SK hynix’s Gold P31, a top pick to consider for efficient computing. We also threw in Samsung’s 970 EVO Plus, which comes with the company’s V5 92-Layer V-NAND TLC, and the 970 Pro with V4 V-NAND 64-Layer MLC.Īdditionally, we included WD’s Blue SN550 as an entry-level comparison, as well as the high-end WD Black SN750 and Crucial P5. We included an SSD based on Phison’s E16 PCIe 4.0 x4 NVMe controller, the Team Group Cardea Ceramic C440, to see which architecture proves best. ![]() With top specs, it was only fitting to pit Samsung’s 980 Pro up against the best SSDs on the market. ![]() (Image credit: Tom's Hardware) Comparison Products
