ioMeter is the best open source benchmarker out there however they don't fully support OSX, just the worker engine binaries - so iometer itself would have to run on a separate machine. during regular multi application usage of the OS. iow - this is as fast as it gets and in no way indicative of how your drive performs when ~30-50% of its reads and writes are random - i.e. One more thing to add and I don't know if was already mentioned or not tl:dr - this is a sequential test only. Using a MP5,1 with 4x16GB DDRMHz ram in Dual-Channel mode i get around 2400MB/sec read and 2100MB/sec writes with about a dozen apps open. Want to test whether your hard drive performs well Get started with the 10 hard drive speed testers. Im using Disk Speed Test and AJA System Test. Hard drive is one of the most important components that makes your computer operate smoothly. ~> time dd if=/dev/zero bs=2048k of=tstfile count=1024 2>&1 | awk '/sec/ 'Īaaah much more like it. So im curious what kind of throughput others get doing a benchmark speed test on their ram disk.
The system has 16GB of ram, a 3.5 GHz i7 and 512 GB PCI-e (]> 01:19:24 Allow me to demo this on my snazzy new iMac with the PCI-e drive. This prevents caching and artificially inflated read speeds. One additional thing that might be worth mentioning.your test file (tstfile) should be larger than the amount of physical ram.
