For database-heavy workloads, the main features are enterprise NVMe (not SATA SSDs), correct RAID (10/1), persistent IOPS, and hardware redundancy. GTHost and similar GPU hosting companies are fine if your workload genuinely requires GPUs, but they are usually considered luxurious and cost-inefficient for pure database performance.
If your main focus is databases, then hosts such as DedicatedCore are most suitable for you they provide dedicated servers with enterprise NVMe storage, customizable RAID, high IOPS, and redundant network/power setups, which is exactly what databases need for consistency and uptime.With any provider, the major point that needs confirmation is the disk class, RAID controller, and node redundancy, not only the specs that are advertised.
