Hello

I think you should reconsider several of your requirements. Requirements like 1U, 2.5/SFF, rack, etc are probably not the best for what you are trying to accomplish. Do you have a rack in this office or is it some kind of mount for rack systems? Why only 1U?

For small office single server environments I would typically recommend a tower. For a file server focused on storage capacity I would recommend 3.5/LFF. If you are going to use a parity RAID level to maximize storage space then you need to use a good storage controller with write cache(H730).

I would recommend the R540 or the T340. Large capacity SFF drives are much more expensive than LFF drives. All of our storage controllers should support multiple virtual disks. The H330 and H730 support many more virtual disks than you would be using. You can find specifications in the storage controller manual.

Thanks Daniel,

Because budget limit, if R540 price close to R340, then we may choose R540, I still prefer 3.5" HDD as we can choose large amount size, for each 2.5" HDD only provide 2TB Max..

Choose rack mount because we have a rack cabinet and it will save our server room space.
