A 4TB SATA drive using spinning disks (HDD) would have significantly slower I/O performance compared to SSDs or enterprise-grade storage solutions, especially for a heavily used database.
Databases typically require high read/write speeds, low latency, and high IOPS (input/output operations per second). SATA HDDs have lower IOPS and higher latency compared to SSDs or NVMe drives, making them unsuitable for high-performance database workloads.

Open-source software provides access to its source code and typically permits users to modify and redistribute it under the applicable license terms.

CIFS (Common Internet File System) is a protocol that allows file sharing across different operating systems, such as Unix and Windows. It supports read and write access to files and folders on a network share. It is also known as SMB (Server Message Block).

Since port 3306 (MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to check network firewall rules. It's possible that the workstation's firewall or network- level security rules are blocking outbound or inbound traffic on port 3306, which is required for database access.

If a server has two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight- drive RAID 10 set for data, then the most likely failure scenario that caused the server to crash and not boot is that a drive failed in the OS array. RAID 0 is a RAID configuration that stripes data across two or more drives without parity or redundancy. RAID 0 offers high performance but no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 10 is a RAID configuration that combines disk mirroring and disk striping with parity. RAID 10 offers high performance and fault tolerance. RAID 10 can tolerate up to one drive failure per mirrored pair without losing data or functionality.
