GTHost is generally known for offering affordable dedicated servers with quick deployment, and many users have had good experiences with their network and pricing. However, before committing, I would recommend checking recent reviews regarding support quality, hardware replacement times, and network performance in your target region.
For your requirements (64 GB RAM, 2 × 2 TB SSD/NVMe, and high bandwidth), it is worth comparing a few providers and testing their support responsiveness before making a long-term decision. In high-traffic media delivery scenarios, reliable support can be just as important as the server specifications.
