I'm seeing low numbers vs AnandTech's review of the 512GB Samsung 950 Pro (https://www.anandtech.com/show/9702/samsung-950-pro-ssd-review-256gb-512gb). But I've never properly benchmarked a drive before, plus my test rig is bit lower tier than the reviewer's (though same generation). I'm either:
1. doing the test wrong
2. reading the test results wrong
3. was scammed on eBay
I'm using Earle Philhower's "ezFIO" wrapper for regular ol' FIO (https://github.com/earlephilhower/ezfio) on a Dell Optiplex 9020 running a Debian Linux distro.
I understand AnandTech uses FIO for benchmarking (see http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=threads/how-best-to-benchmark-test-nvme-in-linux.2577474/) but I opted for ezFIO over learning to roll my own jobfile or whatever. I'd think they're comparable but I'm seeing, for example, a max. ~1500MB/s sequential read versus the review's 2500 MB/s.
Is my hardware insufficient and limiting it that badly or have I misread the results? Covering the basics, the boot and OS are on a separate SSD connected via SATA while the Samsung 950 Pro is in a PCIe adapter card plugged into the only PCIe Gen3 slot, which is 16x while the adapter is, I believe, 4x given the short length (doesn't seem to prevent it working). The 950 Pro had no partition table and I set it up using gparted with one ext4 filesystem taking all the space.
My hardware vs. AnandTech's 2015 SSD test rig is:
CPU — i5-4570@3.2GHz vs. i7-4770K@3.5GHz
Chipset — Intel Q87 vs. Intel Z97
Memory — 2x4GB + 2x2GB DDR3-1333 vs. 2x8GB DDR3-1866
I've taken a screenshot of ezFIO's output but basically it's all less than expected. This is all new to me, so any help is appreciated.
