Synology DS1621+ NAS Server

Product Information

Measures temperatures from –55°C to +125°C in 0.5°C increments. Fahrenheit equivalent is –67°F to 257°F in 0.9°F increments PCIe add-in cards, expansion units, and storage drives are sold separately. Refer to the compatibility list for compatible devices. More caution is needed when selecting a 10GbE adapter, however, as Synology is rapidly shrinking its third-party hardware compatibility list and focusing more on its own solutions. When we installed the same Emulex dual-port 10GbE adapter we’d used to test the DS1618+, the DS1621+ hung during the boot phase and would only accept a dual-port Intel X520 10GbE adapter. Synology DiskStation DS1621+ review: 10GbE performance Synology SNV3400 series M.2 NVMe SSD drives can be installed through the built-in M.2 slots to enable SSD caching or create SSD storage pools. Drives are sold separately. In any case, installing the SSDs onto the server is super easy. The two M.2 slots are inside the server's left wall. Take the first and second drive bays out, and you can reach them. Synology DS1821+: 10Gbps NIC card upgrade

If you're mulling over the two, that is the only point you should consider. Synology DS1821+ vs DS1621+: Hardware specifications Model If you're using the DS1621+ and want to upgrade to the DS1821+ to take advantage of the two extra drive bays, the process is the same as when you migrate from one Synology server to another. User-defined temperature settings are stored in nonvolatile memory so parts may be programmed prior to insertion in a system. Temperature settings and temperature readings are all communicated to/from the DS1621 over a simple two–wire serial interface.What's most notable, though, is that it's basically the DS1621+ plus two drive bays. The two share the same hardware specs -- both are the firsts from Synology that use an AMD Ryzen quad-core CPU. The DS1621+ comes populated with 4GB of ECC DDR4 in one slot of two slots, and can support up to 32GB. Despite the higher price, it’s great to see the ECC RAM used for improved protection against data corruption.

The DS1621+ has a PCIe slot, which supports a range of 10GbE networking cards.

In other words, if you're looking for the best 10Gbps NAS for the home (or small office), you're at the right place. It's even older than that -- Synology first announced it in 2020. But it's still going to be the latest Synology 8-bay NAS for homes and SMBs for a while -- Synology likely won't release its replacement this year. So on the Xfinity/Comcast IPv6 thing. Before three days ago when “they changed things” during an 0200-0430MST (local) outage… IPv6 worked. The 5-bay DX517 expansion unit uses an eSATA connection, which caps at 5Gbps, to connect to the server. By the way, you should only cache a hard drive volume. If you use SATA SSDs for storage, caching is unnecessary. On top of that, if you decide to cache, it's also a better idea to upgrade the server's network to 10Gbps -- more below -- or at least use its Link Aggregation feature to get a 2Gbps connection out of its two Gigabit ports.
