![]() ![]() 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. #Acer samsung nvme driver fullThe FA100 recovered 44GB of data within five minutes of idle time and reclaimed nearly the full SLC cache after half an hour. After writing an additional 413GB, the FA100’s write performance degraded once again to 230 MBps on average.But the Acer drive features solid SLC cache recovery. The FA100’s write performance degraded from 2.8 GBps to 1 GBps after writing 218GB of data. In terms of sustained write performance, the FA100 displayed decent performance given its DRAM-less design. 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 When upping the workloads to higher queue depths, however, the Acer FA100 falls behind most competitors. At a queue depth of 1, the FA100 trails the Samsung 980 and SK hynix Gold P31, but outperforms high-end SSDs such as the Crucial P5, Samsung 970 EVO Plus, and WD_Black SN750. ![]() However, random performance looks fairly strong at low QDs. In ATTO, Acer’s FA100 is among the slowest SSDs when tested at smaller block sizes. ![]()
