Unlike past Synology NAS devices that we've looked at, the DS410j doesn't feature a SO-DIMM for its memory. Instead, memory is soldered directly to the PCB. There is a single memory chip providing a 128MB capacity, the Elpida E1116AESE module works at 800MHz using CAS5-5-5 timings.
Also featured on the PCB are the Marvell 88SX7042 and Marvell 88E111SR-NNC1 controllers. The first is a PCI Express 4x SATA controller with support for up to 4 ports, while the other provides the DS410j with Gigabit LAN. It's also worth mentioning that Synology has gone with a 100% solid capacitor design, making this a more durable product.
The motherboard has no SATA data or power connectors as found on previous models. Rather there is a PCI Express x4 port which connects to another PCB featuring the hot-swappable connectors that rise up into the hard drive bay area. There are also two 3-pin fan headers located on the PCB which are used by default to power the dual 80mm fans.
There is just one more obvious ingredient that must be added: the hard drives. The DS410j compatibility list is quite broad, supporting a wide range of Hitachi, Maxtor, Samsung, Seagate and Western Digital hard drives.
Additionally, Synology is offering their NAS products with various pre-installed hard drive configurations which they've told us is a popular choice among consumers. The version they sent us featured a pair of Samsung HD753LJ (750GB) hard drives. We are not completely certain about the asking price for this particular version, Newegg.com lists 2TB and 4TB models for $600 and $900, respectively.
