On paper the 850 EVO is advertised with 98,000 IOPS while the S3510 is only advertised for 20,000 IOPS. The Evo can only handle the load for a few seconds (and only if the drive has enough free space, so it can use pseudo SLC cache) until the performance will heavily drop. +To compare your drive against these numbers run: +```bash +fio --ioengine=libaio --filename=/dev/sdx --direct=1 --sync=1 --rw=write --bs=4K +--numjobs=1 --iodepth=1 --runtime=60 --time_based --name=fio +``` + That is why for SLOG enterprise PLP drives are recommended.
