Western Digital 500GB WD Red SN700 NVMe Internal Solid State Drive SSD for NAS Devices - Gen3 PCIe, M.2 2280, Up to 3,430 MB/s - WDS500G1R0C

I picked up two 500GB WD Red SN700 NVMe SSDs for use in a RAID 1 configuration inside my QNAP TS-464 NAS, and they’ve been nothing short of excellent.These drives are specifically designed for NAS environments, and it shows. They’re optimized for 24/7 operation, with high endurance ratings that far exceed those of typical consumer NVMe SSDs. Setup was seamless—the QNAP recognized them instantly, and I had my RAID 1 volume up and running without a hitch.I’m currently using the SSD volume for QTS system files and apps, and the performance improvement has been significant. The NAS is much more responsive, apps load quickly, and everything feels snappier compared to using traditional HDDs alone.Thermals have been great too, especially with the addition of low-profile heatsinks (I used the MHQJRH M.2 2280 model, which fit perfectly in the QNAP). There’s been no sign of thermal throttling, even under sustained activity.Down the road, I plan to add a third SN700 and migrate the array to RAID 5, which will give me more usable space while still maintaining redundancy. Knowing these drives are built for NAS workloads gives me confidence they’ll hold up long-term.If you're looking for reliable, NAS-rated NVMe SSDs for cache, system volumes, or storage pools, the WD Red SN700 is an excellent choice. Stable, fast, and built for the job.

I added two Western Digital 500GB WD Red SN700 NVMe SSDs to my Synology NAS DS1821+, and they've been working flawlessly. Setting them up as an SSD read-write cache has noticeably improved the overall performance and responsiveness of my NAS.One tip I'd like to share is allocating only 75% of the SSDs' capacity for the cache. By not filling them up to 100%, I've found that the SSDs maintain optimal performance and longevity. This prevents potential slowdowns that can occur when drives are fully saturated.Installation was straightforward, and the drives were immediately recognized by the Synology system. These SSDs are specifically designed for NAS devices, ensuring reliable operation under constant read and write demands.If you're looking to enhance your NAS setup, I highly recommend these WD Red SN700 NVMe SSDs. They've exceeded my expectations and have become a valuable part of my storage solution. Five stars!

Great product! Used it for my Unify Cloud Gateway Fiber for Unify Protect. Worked perfect.

A significant upgrade for your Synology 923+ NAS. During install the system DID recognize that it wasn't Synology brand NVMe however it didn't impact setup at all.One important tip, SSDs perform best when they're not full. It's recommended you set it up to use only 80-90% of the full capacity. So even though you're buying 1TB, consider allocating only 800 GB to the volume. This should increase SSD lifespan, help maintain consistent performance and is best practice for 24/7 systems like NAS.

Bought two of these 1TB NVMe SSDs for my Synology NAS in November 2024. The first one failed within 90 days and the second one failed in July 2025.My Western Digital Red hard drives are running great and I would recommend those, but I won't buy Western Digital NVMe SSDs again.

Bought 2 for read/write SSD cache for my Synology. Snap right in so easy to install. No issues so far. Hit rates stabilized at around 70% which is great for me. Bit on the expensive side, but I hope the peace of mind for the NAS graded reliability will be worth it.

Working as app and docker location for NAS. This is a short term review, hoping it holds up over time. The temps idle around 35 C.

I've purchased a total of 4 of these (500 gig size) for use as cache in a pair of Synology NAS. They are now right at 2 years old, and suddenly one has died. I will update if Western Digital (or now SanDisk) refuses to honor the warranty, but they've never given me a problem before. I'm not happy one has died, but things do happen. I'm surprised it took 2 years, usually they either die right away or last well beyond their warranty. In general I've been satisfied with Western Digital NAS products despite the SMR fiasco, but this is the first SSD NAS devices I've purchased. I am happy they come with a 5 year warranty!
