SSD: Choose SSD for high-speed performance, low latency, frequent read/write operations, and critical applications requiring durability (e.g., databases, VMs, and analytics). HDD: Opt for HDD when cost-effective large storage capacity is the priority, and access speed is less critical (e.g., backups, archives, or cold storage). HDDs are suitable for large, continuous data read/write operations like video streaming, data logging, or backups, as they perform comparably to SSDs in such scenarios but at a lower cost.

SSD (Solid State Drive) - Much faster read/write speeds and higher IOPS, ideal for high transaction rates and quick data access. - Best for transactional databases and applications requiring high-speed access. - More resilient to physical shock and have no moving parts, making them less prone to mechanical failure. HDD (Hard Disk Drive) - Lower cost per gigabyte; suitable for large storage needs. - More prone to mechanical failure due to moving parts but generally last longer in terms of data storage capacity. - Ideal for archival storage and backups where speed is less critical.

From my experience SSDs have become the only practical choice for database storage. Their speed and reliability are essential for the performance demands of modern applications. HDDs just can't keep up with the intensive read/write operations that today's databases require. Investing in SSDs has proven invaluable for our clients, ensuring their data storage keeps pace with their growing needs.

Using faster disks for heavy load tables and large indexes can achieve optimal response time for database , also for database with high transactions (TPS) rate of generating Redo logs, Wal files is a important parameter and put these files on SSD disks can minimise Loads such as Commit waits and other wating events related to flush Redo log buffers on disks.

SSD Will benefit faster query execution and reduce the I/O bottlenecks and quicker data retrieval so it will increase overall DB performance. It will definitely a go ahead with SSD.

I will always choose SSD over HDD any day, any time. I would rather pay for a system that is durable, reliable, less power-consuming, and faster, even though it is more expensive and has less storage space. It is wise to pay more for a secured service than face a lawsuit for data loss or breach, and that is why most corporations go above and beyond to ensure data protection.

Hoy en dia no es caro tener SSD. El cuidado no debe ser por fallos mecánicos, sino electrónicos. Creo que los HDD estan en vias de extensión

SSD it is faster and no noise from spinning, with vast storage. As part of cutting edge system, some old desktops HDD are being converted to SSD in order to improve its performances, fast booting

Data would be stored and received faster with SSD drives. As already mentioned there are no moving parts; they operate more quickly. Perhaps there is still a good use for old drives but probably only as a last resort in a pinch.
