Single Client Performance - CIFS & iSCSI On Windows
The single client CIFS and iSCSI performance of the ioSafe 1513+ was evaluated on the Windows platforms using Intel NASPT and our standard robocopy benchmark. This was run from one of the virtual machines in our NAS testbed. All data for the robocopy benchmark on the client side was put in a RAM disk (created using OSFMount) to ensure that the client's storage system shortcomings wouldn't affect the benchmark results. It must be noted that all the shares / iSCSI LUNs are created in a RAID-5 volume.
The market doesn't have too many 5-bay NAS units. In fact, the only other 5-bay NAS unit that we have evaluated before is the LaCie 5big NAS Pro from early 2013. That unit was also based on the Intel Atom D2701, but carried only two GbE links instead of the four in the ioSafe 1513+. In terms of encryption support, vendors have two approaches - encrypt a particular shared folder or encrypt the full volume. Synology only supports folder-level encryption in DSM. The graph below shows the single client CIFS performance for standard as well as encrypted shares on Windows.
We created a 250 GB iSCSI target and mapped it on to a Windows VM in our testbed. The same NASPT benchmarks were run and the results are presented below. Note that we also present numbers for the 'Single LUN on RAID' mode which is supposed to provide the best access performance. It does indeed perform better with write workloads, but loses out on read workloads to the standard file-based LUNs.

I hope we don't have readers chiming in about how they can build a better DIY NAS than the one presented here :)hodakaracer96 - Wednesday, August 13, 2014 - link
I for one, was hoping for fire and water testing :)Samus - Wednesday, August 13, 2014 - link
Some good "tests" on youtube:https://www.youtube.com/watch?v=qm4J_1jFxik

I wouldn't bet money on this product surviving an actual fire. Insulation seems too thinganeshts - Friday, August 15, 2014 - link
I hope you are kidding :) ioSafe's products have been proven to work - they have many real world success stories. Quite sure they can't have big-name customers if they don't prove that they can really protect the drives as per the disaster specifications quoted. Just for reference, a picture of one of the 1513+ units subject to both fire and water damage is in our CES coverage: http://www.anandtech.com/show/7684/synology-dsm-50...ddriver - Friday, August 15, 2014 - link
Well, looking at the youtube videos of fire test I am not really impressed. Surely, it will probably survive a mild and short fire with not much material to burn, but being in a serious blaze and buried in blowing embers it will not last long. A regular NAS unit put in a small concrete cellar with no flammable materials in it has better chances of surviving.And this probably has to do with how they test their products, which I can logically assume is safe controlled fires carefully estimated to not exceed the theoretical damage the unit can handle. But how many houses did they torch to test their products in real life disaster situations? My guess is zero :)

I mean, it will most likely survive a plastic trash can full of paper catching fire and burning out next to it, but will it survive an actual blaze disaster? I highly doubt it.In other words, I don't doubt the product will survive what they claim it can survive, I doubt that the disaster specifications they quote reflect real world fire disasters well enough. They will probably suffice for "fire accidents" but not really in "fire disasters".

Does this convince you?http://geardiary.com/2009/08/04/could-your-hard-dr...
As for real-life situations, they are claiming protection for the following fire situation: 1550°F, 30 minutes per ASTM E-119
I remember reading a post about some statistics regarding how fast fire services respond to hourhold fires, and ioSafe's protection circumstances fall within that. Anyways, this product is targeted at SMBs / SMEs who have buildings as per fire marshal codes. Any blaze in such a situation is probably going to be controlled well by building sprinklers.

It is the 1550 F number that bothers me. That's below 850 C, and even wood and plastic burns at almost 2000 C using air as oxidizer. Most of the stuff that is flammable burns around 1950 C, so targeting the product at 850 C pretty much excludes direct fire damage. E.g. if you have a wooden cabin and if it burns to the ground, the data is very unlikely to recover.That is why I drew a line between "accident" and "disaster". This product will do in the case of fire accidents, but in the case of a fire disaster its specs are just not enough.
So, it is a "fireproof" product for buildings with anti-fire sprinkler installations and with good accessibility for fire services. In short, it doesn't protect in the case of fire disasters, but in the case of fire accidents and the water used to put them out.

Hi ddriver-The average cellulose building fire temps are between 800-1000F for about 10-15 minutes. We've been in many fires and have a record or zero data loss for fire disasters in the real world. Most of the building damage is actually caused by firefighter hoses - not the actual fire. The absolute temperature (1500, 1700, 2000...) is not as important as the duration actually. Think of a pot of water boiling on the stove - as long as there's water in the pot, the pot doesn't melt because the endothermic action of the boiling water (212F) keeps the pot from melting. The flame temp could be anywhere between 800 and 3000+? and the water would still boil at 212F (assuming sea level pressures). You could use an aluminum pot (which melts at 1100) and still be ok. Once the water runs dry, then you'll ruin the pot. It's actually the same with all fire safes (and ioSafe). There's water chemically bound to the insulation that works to cool the inner chamber and keeps it at survival temps. Our fire test standards is hotter and longer than typical building fires and the systems we sell typically can go double the standard just to be conservative.
The fire protection technology is not new. We use the same proven techniques that have been around for 100 years. What unique about ioSafe is how we combine fire/water protection with active computers – managing the heat produced during normal operation while protecting against extreme heat possible during a disaster.
As Ganesh has said, we test both internally and externally (with the press watching and recording!) in both standard and (ahem) very non-standard ways at times - we've NEVER failed a demo. One of these days, I'm sure a gremlin's gonna pop up and we'll get recorded by the press as failing a disaster demo (because a HDD refuses to boot) but that's the risk we take. Our stuff's legit.
And btw, a cellar is a great place for tornados and fires but not so good for water main breaks or river floods – we’ve seen it all :)
