Ion's generally chew up about 24-50W which adds $XX to an annual energy bill. Ion boards generally only support upto 4 devices (some upto 6), but may have a PCI/PCI-E slot which can be used to add more. Note that in most cases, ION boards include realtek network chips which have been noted as providing poor network throughput, and the PCI/PCI-E expansion slot may be needed for an intel network card to improve throughput.
4) Yes .. standard Samba.
Note that Samba performance is distinctly slower (and occasionally flaky) compared to NFS in linux.
8) DLNA/UPNP server doesn't work in this unit.
12) T.B.D - Esata didn't work.
16) Esata didn't work. T.B.D.
17) Standby (10, 30, 60 or 120 minutes) & Hibernate.
Commentary: The LG N2B1 seems to be prety standard for a NAS unit, with approximately 17MB/s Read for a single drive (or Raid1 configuration), and upto 31MB/s Read for a striped (Raid0 configuration). These results are for sustained file reads (lagre files) that will not fit into the NAS's RAM. Small writes less than 64MB will read & write at speeds of upto 55MB/s & 80MB/s respectively due to the NAS's caching.
Miscellaneous note: Single drive NAS performance is limited to approximately 67MB/s for single drive NAS configurations and <100MB/s for professional raid setups. Generally, commercially available NAS setups are limited to 17-25MB/s (read) for single drive configurations, and 30-50MB/s for performance raid configurations.
By comparison, a Windows XP (pro) PC to Windows XP (pro) PC transfer from the server (using a realtek network chipset) resulted in 18MB/s transfer speed for reading, and 10-12MB/s writing speed across a gigabit network link. (2.5GB file tested using XXCOPY with a mapped network drive).
Similarly, various flavours of linux result in hitting the single drive 17MB/s read (9MB/s write) in server (realtek onboard nic) to Windows XP (pro) PC. (2.5GB File Tested using XXCOPY with a mapped network drive).
To be tested is intel Nic's which actually have a network processor onboard, compared to marvell & realtek, where all network activities are done in software (CPU) which can greatly increase network throughput.
Anecdotal evidence suggests that realtek peak at 30MB/s transfer speeds, Marvell achieve 35MB/s, whereas an intel card will achieve upto 55MB/s in the same setup.
