![]() Synology rates the SNV3400 at 205,000/40,000 sustained 4K random read/write IOPS. With two drives required, at $149 each, expect to pay ~$300 more per NAS for SSD drives. Synology recommends purchasing their SNV3400 400GB M.2 NVMe SSD drives. Further, in Storage Manager, you can view the cache hit rate for the past day/week/month. Synology provides a Cache Advisor in DSM 7.0 to determine what size cache you need. Now, dual M.2 SATA SSD expansion slots are built into the DS1821+, so you only need to buy (two) M.2 SSD drives. With the DS1817+ and the DS1819+, it was necessary to buy a separate M.2 SATA SSD expansion card, adding cost to your NAS purchase. Like the DS1819+, the DS1821 has 4GB DDR RAM and it is expandable to 32GB. Additionally, the DS1821+ supports PCIe v3 (with a peak speed of 16Gbps). In terms of hard drive connectivity: DS1821+ supports SATA III (6Gpbs). But, Synology claims that the DS1821+ can achieve up to 113,458 4K random read IOPS and 2312 MB/s sequential write speeds, which is 177% higher 4K random read IOPS and 76% faster sequential write speeds than the DS1819+. Both are 64-bit, quad-core CPUs with a hardware encryption engine (AES-NI). The DS1821+ has the AMD Ryzen V1500B quad-core 2.2 GHz, which is a significant upgrade over the DS1819+’s Intel “Denverton” Atom C3538 CPU. Like the DS1817+ and the DS1819+, the DS1821+ is an eight drive bay NAS. ![]() Hardware Specs A Significantly Faster CPU This is especially useful if you use your Diskstation, not just for file sharing, but as an application server. The speed increase makes the DS1821+ a much more compelling upgrade than previous revisions.
