4 out of 5 eggsGreat if used as intended

Pros: This thing works great if you use it with a USB stick or a bus-powered USB Hard Drive like a WD Passport.

Cons: Did not work with several external HD's that were 7200rpm powered from ac adapters. Not sure why but this thing only works with bus powered usb drives.

Other Thoughts: If you want something to use with a bigger external HD get a different model.

5 out of 5 eggsGreat Low Power NAS

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 speed is more than sufficient for my use - especially since the backups are run at night.

Note that the drive is formatted as EXT3 - this gives the best performance compared to others. Also, I find that there are a few "windows drivers" available that can read EXT3 drives - which is great in case the NLSU2 fails, I will still have access to the files from Windows. (much better than NAS drives based on ReiserFS - did not any good Windows drivers for those).(There is always the LiveCD approach to recovery in any case).

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).

Other Thoughts: 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.

Transfer Speed:
I did a simple test transfering a 4571MB iso file and recorded the time it took (all within the same local 100Mbs network).

1) PC to another PC - 8 mins (34.38GB/hr)
2) PC to a laptop via wireless-G - 34 mins (8.84GB/hr)
3) PC to NLSU2 - 20 mins (13.7GB/hr)
4) PC to *turbo* NLSU2 - 17 mins (16.13GB/hr)

Note *turbo* in (4) indicates the results after I modified the hardware (removed resistor) to increase clock speed (voids warrantee). Also after I increased the clock speed, I noticed that the web browser interface loads much faster.

I bought this from another site (been Out of Stock at NewEgg for a while) so this review is similar to review I made at the original site.

3 out of 5 eggsOkay for Linuxers

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 then one of them can be NTFS. See "other thoughts" on what happens if you just use a single NTFS volume.

I got better results by replacing the standard firmware with Debian Linux. This little guy is now a file server, time server, and print server for a handful of Windows and Linux boxes.

This little guy will handle big backups (60+ GB) as long as you aren't in a huge hurry. Run them at night.

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 stay synchronized with a network time source. This can be a problem if you depend on file time stamps to tell which version of a file is newer.

Other Thoughts: 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. You'll be stuck with the default admin account and a factory-default password.

There's a large community of folks who support this thing with after-market software, and you'd be amazed at what folks do with it. I have several projects in mind myself, and will probably buy a few more of these. If you like tinkering it's an incredible deal.

3 out of 5 eggsUgh

Pros: None

Cons: I would have been better off just using an old computer to host out my external drives. It is not worth the cost if you have an old computer that you can use.

4 out of 5 eggs

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.

Other Thoughts: its not a bad thing to have when you want to share music, videos, or other stuff between a small network.

5 out of 5 eggsNSLU2, Very Useful, Very Economical

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.

Other Thoughts: 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.

I've backed up data to floppies, until it became too cumbersome, then to Zip drives, until I started experiencing the infamous 'click of death'. I moved on to tape backups, but never really liked them. Finally, a backup system that works, works, works.

I use an NSLU2 attached to my home network. There are two Seagate 320GB drives attached to the NSLU2, but only one is available for backup. The second one is used to backup the first one. Simple. Not as good as RAID, but I have very little money in the setup, and it uses a lot less electricity than an actual server would - something that is becoming increasingly important.

It is so much better than any backup from the past - not only can backup everything to it, but it is always available via my local network when I'm at home, or via VPN when I'm

2 out of 5 eggsNot a happy camper

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 data back, but what kind of test cycle did this product have?

Other Thoughts: 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. And cmon, breaking resistors off, what kind of world are we living in? Linksys - if you're going to play the resistor game, why don't you just give us a turbo switch and save us the hassle?

I must say I love your wireless routers, which is why I was so surprised and disappointed. Fix the bugs, up the speed and provide better support for NTFS and you'll have one great device.

5 out of 5 eggsAwesome Product

Pros: Easy to install. Does what it is suppose to. Great management for users and groups. Easy to map drives to it.

Cons: None

Other Thoughts: Not the best web interface. Easier to map drives then to use web based file browsing.

3 out of 5 eggsHow to turn a turtle into a rabbit

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.)

Other Thoughts: 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. I also reformatted my external drive using the recommended file system for the nslu2 box and now my transfers are very fast. Copied over 120GB in a couple hours. Google search nslu2 remove resistor for simple instructions on how make your nslu2 into a rabbit.
