Miscellaneous Aspects and Concluding Remarks

It is expected that most users would configure the ioSafe 1513+ in RAID-5 for optimal balance of redundancy and capacity (reflected in ioSafe's decision to ship the units pre-configured with SHR 1-disk fault tolerance). Hence, we performed all our expansion / rebuild testing as well as power consumption evaluation with the unit configured in RAID-5. The disks used for benchmarking (Western Digital WD4000FYYZ) were also used in this section. The table below presents the average power consumption of the unit as well as time taken for various RAID-related activities.

ioSafe 1513+ RAID Expansion and Rebuild / Power Consumption
Activity Duration (HH:MM:SS) Avg. Power (W)
Single Disk Init - 37.9 W
JBOD to RAID-1 Migration 11:40:48 49.59 W
RAID-1 (2D) to RAID-5 (3D) Migration 38:34:47 59.46 W
RAID-5 (3D) to RAID-5 (4D) Expansion 31:33:19 69.95 W
RAID-5 (4D) to RAID-5 (5D) Expansion 33:46:59 81.31 W
RAID-5 (5D) Rebuild 22:57:12 78.89 W

One of the issues that we would like Synology to address is the RAID expansion / migration / rebuild durations. Though we don't have the full corresponding data from similar (read, 5-bay) competing units, the expansion durations with QNAP NAS units and rebuilds with the Seagate NAS units are much shorter compared to the ones in the table above.

Coming to the business end of the review, there are two different aspects of the ioSafe 1513+ to comment upon. The first relates to the software platform from Synology. DSM 5.0 is arguably one of the most full featured COTS NAS operating systems around. Its popularity is even reflected in the fact that specific viruses have been created for the platform (though it is also an indication of the security weaknesses that Synology has been actively patching in the recent past). The mobile apps and NAS packages extend the functionality of the appliance to provide a comprehensive private cloud experience. SMB features such as virtualization certifications / iSCSI support further enhance the appeal of the ioSafe 1513+ for enterprise users. All the plus points of the Synology 1513+ (including the performance, capacity expansion, high availability, hot-swappable fans etc.) translate as-is to the ioSafe 1513+.

The second is obviously related to the chassis design that makes the ioSafe 1513+ one of the most unique products that we have evaluated. ioSafe continues to impress us by scaling the disaster-proofing techniques to handle more and more complicated scenarios every year. The ioSafe 1513+ is an awesome piece of engineering aimed at solving the very relevant issue of protecting data from disasters. Fire protection is rated for 30 minutes at 1550°F (ASTM E-119) and the unit's drives are kept safe even in 10 ft. deep water for 3 days. ioSafe provides the option to purchase a Data Recovery Service (DRS) scheme along with the unit. The DRS period can be extended at a simple rate of $2.99/TB/month. The only points that consumers might complain about are the limited 'qualified hard disks' list, fan noise and the cost of the units. From our evaluation, we believe that the unit is best operated in an air-conditioned server room where fan noise should not be an issue. Some of the qualified hard disks are suitable for usage only at ambient temperatures lower than 30°C, but neither that nor the cost are likely to be factors for SMBs and SMEs that constitute the target market of the ioSafe 1513+.

    Thanks for the input. BTW, where I come from, "cellar" does not imply "basement" - our cellars are usually on floor levels, tiny room, around 1 m^2 for general storage purposes, no water mains no nothing. Closer to what you may call "pantry" in the US. Cultural differences... me'h. Nothing to burn and nothing to flood in there. Plus noise in the cellar bothers nobody.

    Never failed a demo - which exactly proves the point I make earlier about being careful with controlled fires. That would create the illusion your products are flawless and someone's gonna buy one expecting it to survive his fancy wooden and lacquer soaked cottage burning to the ground which I am willing to bet it will not. You should really draw the line between "office fire accidents" and "fire disasters" just for the sake of being more realistic and not deceiving consumers, deliberately or not. People are impressed by big numbers, and could easily be impressed by the 1700 F number, absent the realization most flammable materials burn at significantly higher temperatures. Every engineer knows - there is no such thing as a flawless product, the fact you never had a failed demo only goes to show you never really pushed your products. With those zero failed demos you will very easily give consumers the wrong idea and unrealistic expectations, especially ones who are not educated on the subject. You SHOULD fail a few demos, because it will be beneficial for people to know what your products CAN'T HANDLE. A few failures in extreme cases will not degrade consumer trust as your PR folks might be prone to believing, it will actually make you look more honest and therefore more trustworthy.

    I mean better you cross that line with a test unit than some outraged consumer going viral over the internet how your product failed and he lost his life work ;)

    Hi ddriver-
    As mentioned, our fireproof tech relies on proven methods that are over 100 years old. Appreciate the heated skepticism though. As an engineer myself, I agree that no product is flawless and everything (including our own products) have their limits. I take back the "never failed a demo" comment. We did some gun demos with shotguns (passed) - got a bunch of flack for ONLY using shotguns so we redid the demo with fully auto AR-15's - blew holes completely through the product and of course failed...sometimes. Fun demo though.

    ddriver: I'm a firefighter and can confirm that, based on the specs, these units would indeed withstand a typical structure fire.

    Dear Mr. Moore,

    I'm really glad that you actually follow up with the public opinion.

    I'll try to use the opportunity and use it to ask you whether you are planning to build a unit with non-Intel CPU, rather with AMD/ARM/Marvell/etc.? A unit that can handle the latest industry standards for on-the-fly encryption without sacrificing the performance even a bit?

    Also, besides the physical integrity and resiliency tests that you are conducting, do you do similar penetration-testing for data integrity? I mean, with well-known independent hacker/pen-testing communities? With all the fuzz around govt. agencies putting backdoors virtually everywhere, it's of extreme importance for the piece of mind of extreme paranoics (like me), to know how hack-proof your devices are.

    Regards,
    Zlob

    Hi Zlop-
    We're constantly working on new products. The 1513+ does use an Intel chip but our other NAS (2 bay), ioSafe 214 uses a Marvell chip. We realize that encryption can be important in many situations and we're always interested in balancing features, cost and speed for our products. Can't make direct comments though on what we have in the pipeline except stay tuned! :)

    In regards to "hack-proof", the most "hack-proof" systems (aka CIA, etc.) don't exist on the internet at all. They're fully contained offline in secured facilities. In fact, ioSafe systems are used in situations like this where offsite backup (online or physical relocation) is not allowed or impractical but the end user still wants a disaster plan.

    Obviously, there's a balance between security, accessibility, cost and speed. If you put an ioSafe system online, no firewall, never update OS/firmware, all ports open with standard admin passwords - expect mayhem. If you put an ioSafe system in a bank vault, offline and turned off it's obviously pretty secure but inaccessible - not very useful. Security can be complicated. Striking the right balance is different for every situation. Our NAS systems are based on the Synology platform which in turn is a custom Linux kernel so it's as safe as you make it generally (like all connected systems) and is susceptible to hackers if setup incorrectly. We're very happy to help you with configuring your device if you have any questions at all about the tradeoffs.

    Ultimately though its under your control. You're in charge of opening or closing doors.

    I second that, for this price... I really want to know it it would last the rated time under fire. Should try it under propane {bbq tank 2300+ C} and and Nat. Gas/wood based flame {1900+ C} To simulate household/industry gas line.

    Well for the $1000 extra, one could buy a 30"x72" inch gun safe that can also be used to store the regular Synology (or a DIY NAS) plus guns, camera gear, and any other valuables. Harder to steal as well- they weight 500-1000lbs.
  • DanNeely - Thursday, August 14, 2014 - link

    Maybe; but good luck using the NAS with the door shut...
