RAID 5 on your Synology DS1621xs+ will indeed provide a good balance of performance, capacity, and data protection. With your 10G network and 24GB of RAM, RAID 5 with three or more drives can enhance read performance significantly, as data is striped across multiple disks. As you add more drives, the performance generally improves, especially in read operations. However, RAID 5 does come with a write penalty due to the parity calculations. Given your need for 8TB of storage, RAID 1 with two 8TB drives is the simplest and most cost-effective solution but offers limited performance and no speed benefits from additional drives. Considering the performance boost you desire, RAID 10 might be a viable alternative as it combines RAID 1 and RAID 0, providing both redundancy and increased performance, though it requires more drives and results in less usable space.
Regarding the drive compatibility issue, using non-Synology approved drives like the Seagate Exos X16 16TB is possible, though you might encounter warning messages which can be disabled. For a cost-effective and high-performance setup, you could opt for three Exos X16 16TB drives in RAID 5, giving you a robust and fast array with ample space. Alternatively, five 2TB drives in RAID 5 would also work, but it might be more expensive and less efficient.
NVMe SSDs for caching are another excellent way to boost performance, especially for read-heavy tasks. If you opt for NVMe SSDs, ensure they have high endurance ratings, such as the Synology SNV3400 or Seagate FireCuda 510, with DWPD ratings of 0.66 and 0.7 respectively.
