Deciding which storage technology to use for your application can be tough. HDD, SSD and NVMe SSD all offer unique advantages that need to be taken into account. Depending on your specific requirements and current budget, choose a storage technology that offers you the most benefits for the lowest costs.
HDD is currently the oldest storage technology in the market. It offers large capacities, at an affordable price. However, HDD is relatively less durable, slower, and takes up more space than other storage options like NVMe and SSD. If your main need is to store a huge amount of data, or maintain a backup of your site, then HDD is a good option. HDD is suitable for setting up a RAID system to store important data files. A RAID system offers high redundancy and fault tolerance that protect your files in case of system failures.
Solid-State Drive (SSD) is the next technology that offers faster accessing time, and more durable service life. It’s also 2.5-inch smaller in form factor compared to HDD. Because SSD allows simultaneous access to data, load times are significantly reduced. Due to their superior features, SSDs are often more expensive than HDDs. With regards to RAID, SSDs offer great flexibility of setting up a redundant network.
Non-Volatile Memory Express (NVMe) utilizes the PCIe interface that offers data transfer rate of 3 GB per second. It’s the ultimate choice for people requiring high IOPS for their applications. NVME SSD may not be an ideal candidate for setting up a RAID system, due to its utilization of PCIe slots. However, if you want 100 times faster access, compared to a typical HDD, smaller storage space, higher reliability, and less power consumption, NVME should be on the top of your list. For high-performance applications that thrive on fast data access, such as a financial trading system, NVMe is your best choice. If, on the other hand, mass data storage is what you need, and speed is not a primary concern, then HDD is better.
