With 2 modern NVMe disks per host (15 GB/s) and pcie 5.0, it should only take 15s to read 30 TB into memory on 63 hosts.
You can find those disks on Hetzner. Not AWS, though.
- jiggawatts 1y agoI don’t understand why both Azure and AWS have local SSDs that are an order of magnitude slower than what I can get in a laptop. If Hetzner can do it, surely so can they! Not to mention that Azure now exposes local drives as raw NVMe devices mapped straight through to the guest with no virtualisation overheads.
