Synology 923+ cache - Enquiries - 01-10-2025
Hello. I’m looking for a recommendation for my ds923 for read-write cache.
I ran the cache advisor in dsm and it said 640gb so I’m assuming 1tb for extra overhead.
I was looking at the WD black, then I saw WD makes a nas rated nvme….. so maybe that’s a better fit?
What is your recommendation?
Thanks again.
RE: Synology 923+ cache - ed - 01-17-2025
Thank you for reaching out! Based on your DS923+ and the 640GB cache advisor recommendation, a 1TB NVMe drive would indeed provide sufficient overhead for read-write caching. Here’s my recommendation:
NAS-Specific NVMe Drives
Since this cache will be running 24/7 and under heavy workloads, using a NAS-rated NVMe SSD is a better fit. These drives are optimized for sustained performance and durability in NAS environments. I suggest:
WD Red SN700 NVMe SSD (1TB)
Designed specifically for NAS use.
Endurance: 2000TBW (Terabytes Written), ideal for consistent cache workloads.
Lower power consumption and optimized for long-term use.
Seagate IronWolf 525 (1TB)
Another NAS-rated NVMe option with strong endurance and reliability.
High durability with similar performance to the WD Red SN700.
Why Avoid WD Black?
While the WD Black is a great drive for gaming and general PC use, it’s not designed for the continuous write operations and higher durability needs of NAS systems. A NAS-rated NVMe like the WD Red SN700 or Seagate IronWolf 525 will better handle the demands of a Synology read-write cache.
