There are i4i instances in AWS which can get you a lot of IOPS with a smaller disk.

Had a look - Baseline disk throughput is 78.12 MB/s. Max throughput (30 mins/day) is 1250 MB/s.

NVMe i bought for 150 dollars with 4 TBs capacity gives me 6000 MB/s sustained

That’s on the smallest instance. I’m sure there’s a reason they offer it, but I can’t think of why. On the largest instance (which IME is what people use with these), it’s 5000 MBps. The newer i7ie max out at 7500 MBps.

You are incorrect, the numbers you are quoted is EBS volume performance. iX instances have directly attached NVME volumes which are separate from EBS.

Sure, now cost out the rest of the server, the racks, the colocation space for racks, power, multiple AZ redundancy, a clos network fabric, network peering, the spare hardware for failures, off site backups, supply chain management, a team of engineers to design the system, a team of staff to physically rack new hardware and unrack it, a team of engineers to manage the network, on call rotations for all those teams.

Sure the NVME is just $150 bro.

You claim I am incorrect, but you don't provide a reference or numbers, which I couldn't find.

AWS doesn't provide throughput numbers for the NVME on iX instances. You have to look at benchmarks or test it out yourself. Similar to packets per second limits which are not published either and can only be inferred through benchmarks.

Are these attached directly to your server or hosted separately ?

i-series instances have direct-attached drives
