The RSH-4S Custom Rackmount Enclosure (Black Textured Powder Coat) from Middle Atlantic is a flexible solution that lets you mount virtually any non-rackmount component in a standard 19" rack or enclosure without making any modifications.

The solution is made possible by custom cutting the face of the rackmount unit to work perfectly with the piece of equipment that you specify. The result is a neatly trimmed installation, with a snug fit and no gaps. Middle Atlantic has more than 8,000 components in its measurement database that can be matched with this unit.

A ventilated bottom on this unit ensures adequate cooling. The included rear brackets prevent the mounted component from sliding out the rear of the enclosure.

Q: 1. I know this is subjective but how much noise to these make? Will it sound like a jet engine sitting on my desktop?

A: Sorry if this was really late, but that will depend what drives you put in. Naturally, HDD NAS like the 1522+ will get louder with more drives so unless you want a very expandable storage solution, you might want to consider a SSD or a SSD based NAS.

Q: 2. Why would you need a M.2 2280 NVMe SSD Slot on a NAS? What are good use cases for this feature?

A: The M.2 2280 slot on the Synology DiskStation DS1821+ 8-Bay NAS Enclosure allows for the NAS to have a sizeable cache to store frequently accessed files. This cache allows for the unit to utilize a read/write buffer to greatly increase the performance of the system.

Q: 3. For the new NVME storage pool feature, are 3rd party NVMEs supported?

Q: 8. Can oui mix HDD and SSD in the same machine, likeby using 3 SSD and 2 HDD? Can we use different different storage capacit for HDD, like 2 16 T and one 12T or they all have to be the same? Thank you

A: It is possible to mix storage types in a Synology NAS, but when doing so it is recommended to use the different types of drive in separate storage pools. A RAID storage volume containing both an HDD and an SSD will only be able to run at the slower speed of the HDD, so the enhanced speed of the SSD would be wasted.

Q: 9. Can I install 2 "Samsung 8TB 870 EVO SATA III 2.5" Internal SSDs" out of the box (no DSM upgrade needed)?
