Issues with V6 approach

• Each NFT should appear only once in the winning block
• Rewards pool exploitation with the immediate LIMIT orders
• Current scheme has led to gas wars
  • We need data to show the percentage of the gns rewards that are sold for matic fees (the same also for the paid LINK)
• Bad actors are front/back running successful bots
• NFTs are losing value since they can not be profitable in the bot arena for most people
• Generally, create a new scheme that will stop being the playground for bad / greedy actors

Overview

Syncing an Ethereum node is largely reliant on latency and IOPS, I/O Per Second, of the storage. Budget SSDs will struggle to an extent, and some won't be able to sync at all. IOPS can roughly be used as proxy of / predictor for latency. Measuring latency directly is arguably better.

This document aims to snapshot some known good and known bad models.

The drive lists are ordered by interface and then by capacity and alphabetically by vendor name, not by preference. The lists are not exhaustive at all. @mwpastore linked a filterable spreadsheet in comments that has a far greater variety of drives and their characteristics. Filter it by DRAM yes, NAND Type TLC, Form Factor M.2, and desired capacity.

For size, 4TB is a very conservative choice. The smaller 2TB drive should last an Ethereum full node until at least sometime 2026, with the [pre-merge history expiry](https://hackmd.io/@hBXHLw_9Qq2va4pRt
