Since my Synology DS1815+ Network Attached Storage (NAS) was getting quite old (6 years+) and 90% complete using old, 6 TB Hitachi hard disks, I thought that it would be prudent to replace it with the latest Synology NAS (with larger, faster, and newer hard disks).
After research, I settled on the DS1621+ with a RAID-5 configuration using 5 x 16TB Toshiba hard disks. The Backblaze hard disk report reported Toshiba's 16TB hard disks as fairly reliableport.
Since the base model of DS1621+ only includes 4GB of ECC DDR4 DRAM, I decided to upgrade to 20GB DDR4 ECC by adding a 16GB DDR4 ECC module from Nemix.
In addition, I planned to add two Synology M.2 2280 NVMe SSD SNV3400 400GB to enable a Read cache and a Write cache to speed up overall NAS performance during periods of maximum activity.
I plan to use the Synology Migration Assistant to transfer data from my DS1815+ to the new DS1621+. However, upon starting the Migration Assistant, I discovered it used the EXT4 file system. Therefore, I used GoodSync to synchronize my files between my PC and Synology.
I enabled the BTRFS file system instead of EXT4 to allow snapshots for easier backup recovery. I upgraded my new NAS to use DSM7 software, which isresponsive.
I ordered the Synology DS1621+ from Office Max (as it was on sale for $816.59). I ordered 5 Toshiba 16TB hard disks from Sabre (an Amazon seller) since the disks were priced at $319.26/disk.
My desired Synology DS1621+ Configuration is as follows:
- Synology DS1621+ NAS (AMD Ryzen V1500B CPU, 4GB ECC DDR4)
- 5 x Toshiba MG08ACA16TE 16TB 7200RPM 512e 3.5" SATA Enterprise Desktop Hard Drive
- 1 x Synology OEM 8GB DDR4 2666 ECC SO-DIMM Memory Module (D4ES01-8G)
- 2 x SK Hynix Gold P31 500GB PCIe NVMe Gen3 M.2 2280 (read and write cache in RAID-1)
Initially, I copied all of my files from my BOSON fileserver to PHOTON (DS1621+) over 3 days. The transfer went pretty well. However, after I upgraded the memory to DS1621+ by adding the NEMIX 16GB SO-DIMM, I started to experience regular crashes.
I tested the memory and ran the Synology test by installing the Synology Assistant desktop app on my Windows 10 PC. The memory test ran for many hours and passed. However, when I looked at the nightly logs, I noticed additional crashes. I decided to remove the NEMIX RAM and return it to the vendor. The Synology NAS worked reliably without the NEMIX RAM.
To replace the defective NEMIX RAM, I ordered a used Synology OEM 8GB DDR4 2666 ECC SO-DIMM Memory Module (D4ES01-8G) for $40 on eBay. I hope that it works more reliably than the Nemix RAM.
Instead of the expensive Synology M.2 2280 NVMe SSD, I decided to try the cheaper SK Hynix Gold P31 500GB PCIe NVMe Gen3 M.2 2280 Internal SSD. I used 2 of these modules as a Read/Write Cache in RAID-1. The Plex package is much more responsive with the SK Hynix cache installed.
