Product overview
The 400GB is the entry capacity in Synology's SNV3510 range, which spans 400GB to 800GB across 2 capacity points. M.2 22110 NVMe cache module for Synology NAS read/write caching.
It attaches over PCI Express NVMe 3.0 x4 in the M.2 22110 form factor. Rated throughput is up to 3,200 MB/s sequential read and up to 2,000 MB/s sequential write.
At 0.68 DWPD this is a read-oriented part: dataset staging, model and image repositories, boot volumes and read-heavy databases. That endurance rating works out to roughly 496 TB written over a five-year term, so it is worth checking against your measured write rate before you standardise on it. Media is 3D TLC.

Questions buyers ask about this part
Will the 400GB SNV3510 fit my server?
This is a M.2 22110 part on PCI Express NVMe 3.0 x4. It fits any bay wired for PCI Express NVMe 3.0 x4. Send us your server model and we will confirm backplane support, firmware level and any bracket or caddy required before you order. That check is part of every order we ship.
What is the endurance rating on the 400GB?
0.68 DWPD. Across 400GB of capacity that is approximately 496 TB of total writes over a five-year term, calculated from the drive-writes-per-day rating. Compare that against your workload's measured daily write volume: if you are writing more than 0.3TB a day to a single drive, ask us about the mixed-use alternatives instead.
Should I take the 400GB or the 800GB?
They are the same drive line in a different capacity, with the same PCI Express NVMe 3.0 x4, M.2 22110 and endurance rating. The 800GB gives you 2.0x the capacity per bay. Where bays are the constraint (a full backplane, or a rack you cannot grow), the larger capacity is usually cheaper per usable terabyte once you count the chassis it saves. Ask us for both on one quote and compare.
How fast is the 400GB SNV3510?
Up to 3,200 MB/s sequential read and up to 2,000 MB/s sequential write, which is what PCI Express NVMe 3.0 x4 allows. Sustained figures under a real mixed workload land lower than the sequential headline. Tell us your access pattern and queue depth and we will tell you what to expect rather than quoting the datasheet at you.
Is this Synology part genuine, and is the warranty intact?
Yes. We supply through authorized distribution only, so the part carries the full Synology manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
Do you offer volume pricing and accept purchase orders?
The listed price is per unit and indicative; tiered pricing applies at quantity. We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.

Specifying a system, not just the part?
Training throughput is limited by how fast data reaches the accelerators, which is why AI nodes are specified with NVMe in front of the GPUs.
