GCE local SSD was the fastest thing around when first released in 2014, but hasn't improved and has since fallen behind. GCE local SSD 4k read IOPs max out at around 200k/volume and 800k/instance w/4 volumes. I haven't measured c5 local nvme yet, but on i3, local nvme volumes run at 100-400k/volume and up to 3.3 million IOPs on the largest instance type (i3.16xl).
- jchw 8y agoHey, you seem to know a lot about this. Can you explain why the docs seem to claim they max out at 680k/volume read IOPS and 360k/volume write IOPS? They seem to be talking about 4k blocks. https://cloud.google.com/compute/docs/disks/performance#type_comparison https://cloud.google.com/compute/docs/disks/performance#type... Is Google being disingenuous? I haven't benchmarked it, but I will say that anecdotally the GCP local NVMe SSDs feel very fast for things like building software compared to other setups I've done on other clouds (AWS, UpCloud.)
