The Promise NS4300N delivered average data transfer rates, but could not quite live up to expectations in some of the tests. The NS4300N was a little behind its competition with the benchmarks that focus on multimedia, for example, and the streaming of HD content. On the other hand, the NAS unit was very good when it came to handling lots of small files.
Unlike in the other RAID modes, the transfer rates in RAID 5 mode were too erratic. As a result, we would not recommend operating this NAS unit with a RAID 5 configuration. The RAID 10 mode delivered the most balanced results in our benchmarks.

The current maximum is 6 GB, made up of four 1.5 TB drives available from Seagate.
I think it should be 6TB
Actually it should be 8TB with the introduction of WD's new 2TB drives.Reply
Can someone explain me why all of these NAS devices are delivering such poor performance over 1GBit LAN? they should be able to get to (more or less) 100MB/s in an uncomplicated raid 0 or such.. is the processor so slow that it can't handle it? not enough cache? what's going on?! :)Reply
Unfortunately, the article is as light on details of the internal components as Promises' so-called datasgeet at http://www.promise.com/upload/datasheet/NS4300NDatasheet_20080709.pdfReply
I would really like a thorough investigation of the internals, including the processor (it's a SoC, but which one), controller chip, and underlying OS. I suspect that it is a BSD derivative due to the lack of published source code available on the promise website, though "Billy" from the promise NAS focus group seemd to indicate that it was Linux using a special promise RAID technology (and not LVM or MDRAID)
There are multiple posts on the avsforums regarding the unit. Of the 25 or so pages that I read, I found that the unit is not a stellar performer, and can be purchased for around $300.
Ultimately, it looks as if you're better off purchasing a full featured $200 Atom based platform, tossing in 4 disks, and utilizing linux LVM/MDRAID for a full fledged NAS.
Seriously? You want us to pay 420 bucks for a POS that will underperform a standard desktop machine you can put together on Newegg for less?Reply
MicroAtx MOBO with onboard video = $80
Dual Core CPU = $60
2 Gigs of DDR2 800 Ram = $24
Case with 6 HDD slots and 4 external slots = $40
Linux Operating System = $0
Total = $204 aka half the fucking price for more hard drive slots and much more customizable.
Seriously who buys this over-priced NAS shit.
Many NAS have poor power supply coming with, it will be a good idea to test with high consumption hard drive or at least talk about this fact... I heard about some NAS system of this type that come unstable with 4 1.5TB hard drive...Reply
For people who talking about the price, don't forget that its a Ready-To-Use solution, a lot of people want this type of gadget but doesn't have the technical knowledge require to setup a linux system able to share data over a network with an web interface for configuration....
So true... not to mention you'd still have enough left over to buy a real RAID card and absolutely blow these things out of the water.

What's wrong with getting a MOBO that does RAID for you?
FreeNAS on an ASUS + RAID board. Does all the protocols not just the three mentioned and FTP. Oh boy, hardly call that NAS-centric.Reply
For RAID10 to be worth the effort the minimum you should use is 3 pairs of hdd (didn't see RAID 10 as an option). 6 hdds with 50% redundancy. So if you were to use 2TB drives you would get a max of 6TB storage and 6TB of redundancy.

RAID 100 or plaid RAID would be the better one to go for. Many small businesses or startups do this. This product couldn't support that.
$420 can buy you a small form case with a number of designs that house many drive bays, mobo with onboard RAID, Graphics, multiple Gigabit ethernet adapters, good powersupply.
You can then go even further and utilise USB2.0 and throw external USB drives for another layer of data sharing.
All this and more and not stuck with a poorly put together product that limits the imagination because of its short comings.
All that and more from your local computer needs store.
Im with you sad panda, i just don't get why people buy these when a cheap low power dedicated box is superior in every way.Reply
As for the additional card, a good hardware RAID card will give you a noticeable speed increase over any motherboard controller, provide more features and better security (failure wise). So if you needed speed and had the cash it would be better for sure.
