Summary: Power Consumption (based on actual measurements using P3): NLSU2 + 320GB Drive = 13W (or 9.522kWh monthly), about $1.58 per month in electricity. A barebones AMD Sempron file server = 76W (or 55.384kWh monthly), about $9.20 per month in electricity costs.
Pros: I got this unit to run as a backup NAS drive and it is perfectly suitable for this purpose, especially since I keep it running 24x7 (it uses very little power). I have this currently attached to a 320GB WD drive (in a Rosewill RX353-S enclosure) and have been using it for a few days now. The spee...
Cons: Unit is shipped under clocked and as others have mentioned - th e firmware has not been updated for years. The current setup is configured with firmware release 2.3 R63. (unofficial release is R76 but not easily available since it is unofficial).
Summary: If you do try to simply use a single NTFS drive with the standard firmware you might get it to kind-of work, but you will be puzzled (as I was). You won't be able to change the admin password, create users or groups, or manage permissions.
Pros: I've heard that most folks who use the unmodified unit can get it to work reliably with "modest-sized" (<= 500GB) USB drives. Just be sure to have an empty drive, and format it using the NSLU2. Don't expect to just plug in a single NTFS drive and have it work. You _can_ plug in two drives, and th...
Cons: The default firmware is challenged, and hasn't been updated since 2005. I was getting really frustrated with its poor reliability with a large (750 GB) disk, which is when I started using Debian. Not too speedy. Expect about 3MB/second throughput on writes. The factory firmware doesn't appear to ...
Summary: its not a bad thing to have when you want to share music, videos, or other stuff between a small network.
Pros: easy way to make use of extra USB hard drives/flash drives for a simple network.
Cons: setting-up on the network is no walk in the park. ya gotta know how to manually set the IP address for the thing so it would work right on the network. once you know what you need to do its no problem really.
Summary: I know many people who have their lives on a desktop or laptop hardrive. They are one crash or one theft away from losing it all. They don't get backups, and they will regret it.
Pros: Cheap. Easy to set up, convenient to use. Without modification, it does exactly what it is supposed to. Allows backing up one attached hard drive to the other - not as good as RAID mirroring, but still decent redundancy. Reliable, uses very little power.
Cons: Cut power to it for very long, and it loses its settings requiring you to set it up all over again. Very slow reads from attached hard drives. Writes are faster.
Summary: I was disappointed that NTFS is only supported on one port. Why do this to me? This device might work great for Linux users. But right now I have 2 NTFS drives with data that I am trying to get on my network and this device is not really doing the trick. I sweat every time I rename a directory.
Pros: Small. Cheap. Looks great.
Cons: This thing ate an entire subdirectory, and I can reproduce this problem. I'm using NTFS. When I rename a directory from the tree view in windows vista explorer it changed the directory into a file! For crying out loud! What are you doing!? I'm able to perform my own data recovery, so I got my dat...
Summary: Totally will void your warranty if you do this but there is a resister ship you can pluck of the mainboard on the NSLU2 and it will restore the poswer to the processor frrrom 133mhz to 266mhz.
Pros: Cheap ! Very easy and fast to set up. Had a new network share in 20 seconds.
Cons: Slow. Connected my 250 GB external hard drive and reading directory structure was slow. ( I do have thousands of NTFS folders and sub-directories.)
