which RAID is fastest

Decide to go with 1817+ for a 16TB raid 10 storage. Use will be as file server-photoserver. 10-12 users on local lan. No internet access. Main consider is speed Both write and read. That’s why no raid 5 or 6 is used. Question is, what offers me more speed? 8 x 4TB disks or 4×8 TB…or doesn’t matter?

The first thing you need to know in order to get the best speed is – more disks = faster speed. The other way of increasing speed is to use SSD drives which are 3-5 faster than HDD. The absolute fastest RAID will always be RAID0, which actually is not RAID. All data will be written simultaneously across all drives. Also, the reading will be done from all drives. To enable RAID protection, you need to look at the way how data is being distributed across the drives. Data on more drives will = faster read speed. So in your case, 8x4TB disks will be much faster than 4x 8TB.

In order to have an even more efficient solution, consider getting a tiered storage solution like TVS-1282T3.

Qnap has created NAS doing exactly what you need. The TVS-1282T3 is not only a NAS but also a Thunderbolt DAS with 4 direct connections. But it gets even better. The built-in 10GbE connections will let users access the storage at the same speed as they would over Thunderbolt. But this time it can be done not just in 10meter radius but 100 (or even further with sfp+ card). Why is this NAS so amazing? It is not only a cold storage solution but also can be used as a storage drive for live editing. It allows you to create an ISCSI connection which tricks all editing software appearing as a new physical drive on a computer. But that is not the best part. It supports auto-tiering. This automatically in the background will move most often used data on SSD drives and less often accessed data on regular hard drives. The functionality increases data transfer speeds massively.
