ioSafe 220+ – Revision 2022

When we reviewed the 5-bay ioSafe 1520+ Network Attached Storage (NAS) earlier this year, we gave it high marks for its extreme durability, strong performance, and rich catalog of applications. We were less thrilled with its hefty price tag and lack of multi-gigabit Ethernet ports, but it still earned an Editors’ Choice award. The ioSafe 220+ (starts at $930; $1,809 as tested) does the same thing. It offers the same fire and water damage protection in a smaller, more affordable two-bay cabinet, and it performed like a champ in our file transfer tests. It also offers a good variety of applications. You’ll pay significantly more for this NAS than a typical two-bay NAS, but if you need to protect your data from disasters, it’s worth the money and deserves the Editors’ Choice award.


You can’t burn this NAS

At 9.1 by 5.9 by 12.0 inches (HWD) and weighing 31 pounds (with drives installed), the 220+ is larger and heavier than a traditional two-bay NAS like the Asustor Drivestor 2 AS1102T ( 6.5 by 4.0 by 8.6 inches, 2.5 pounds). That’s because its black, rugged steel casing uses special insulation designed to keep the inner chamber cool even when outside temperatures reach 1550 degrees F. Additionally, the drives are contained in a sealed, waterproof casing that uses the ioSafe HydroSafe technology to move hot and away from units while protecting them from water damage (whether from flooding or local fire department hoses). The IP68-rated enclosure will remain waterproof for up to 72 hours in up to 10 feet of water. and will remain fireproof for up to 30 minutes.

The front of the cabinet has a removable panel that is held in place with two screws, which can be removed with an included Allen key. Behind the panel is the aforementioned sealed hard drive chamber, which contains two hot-swappable drives secured to their respective drive sleds. You will have to use the same Allen key to access the transmission chamber and remove the sleds.

An on/off button, one-touch copy button, a USB 2.0 port, and five LED indicators are located on the front of the case along the bottom edge. The copy button can be used to back up data from a connected USB device, and the LEDs are for drive activity, system status, and LAN activity.

The back panel has two 1Gbps LAN ports, a power connector, and a USB 3.2 port. You won’t find any multi-gigabit ports here, but the two LAN ports can be added for high-speed connectivity and failover support.

The 220+ features a 2GHz dual-core Intel Celeron J4025 processor and 6GB of DDR4 RAM, and uses the same Synology DSM operating system as the 1520+ and Synology NAS devices like the DiskStation 920+. It can handle a total internal capacity of up to 32TB with 2.5-inch or 3.5-inch drives, and supports Synology Hybrid RAID, RAID 0, RAID 1, Basic, and JBOD. It also supports Btrfs and Ext 4 file extensions.

As with its five-bay sibling, the 1520+, the 220+ is very expensive. Our 8TB test unit, which comes with two pre-installed 4TB hard drives and 6GB of RAM, costs $1,809. (Upgrading from 2GB RAM to 6GB RAM adds $162 to the bill.) A 4TB model with 2GB of RAM will set you back $1,360, a 12TB model is $2,100, the 16TB model is $2,515, and the 24TB model will set you back $2,950. If you prefer to install your own drives, you can purchase a diskless model for $930.

Synology’s DSM (DiskStation Manager) is a user-friendly operating system that makes it easy to manage and configure your NAS. Upon startup, the Windows-like desktop contains various tiles, including the Package Center, Control Panel, File Station, and DSM Help. Two windows to the right of the desktop display system status and resource monitor statistics, including total uptime, CPU and RAM usage, and LAN IP address.

Package Center gives you access to 103 Synology and third-party applications that allow you to use the NAS as a cloud server, Apple Music or Plex media server, video surveillance center, webmail server, backup and more. To create users, set privileges, manage connected devices, and configure file sharing, tap the Control Panel tile. Here you can also configure the firewall and other security settings. Use the File Station tile to access your data through a web browser and to organize folders and files. Tutorials and help articles are available by tapping the DSM Help tile.

When you tap the Main Menu icon in the top left corner of your desktop screen, you’ll see an expanded desktop with all of the above tiles, as well as Storage Manager, Resource Monitor, Universal Search, USB Copy, Active Insight, and Security. Advisor sheets.


An impenetrable NAS with solid performance

The 220+ was easy to install and offered solid performance in our tests. Our review unit comes with two preconfigured 4TB Seagate Ironwolf drives configured in RAID 1, yielding 4.7TB of total storage capacity. I connected the NAS to my router using the included LAN cable, turned it on, opened a browser on a PC that was connected to the same network, and typed http://iosafe:5000 in the address bar. I was immediately taken to a login screen where I entered the default username (admin) with no password, which launched the DSM desktop. I checked the RAID settings, checked the drive health and was ready to test.

We tested the file transfer performance of the NAS by moving a 4.9GB folder containing a mix of video, photo, music, and office document files between the NAS and a host PC, and recorded read and write speeds . The 220+ delivered solid scores on these tests. Its write speed of 90MBps was identical to the score we got from the QNAP TS-253D-4G and faster than the Buffalo LinkStation LS720D (85MBps), but not as fast as the Asustor Lockerstor AS6702T (94MBps). .

Results were similar in the read test: the 220+ got 90 MBps, once again tying the QNAP TS-253D-4G and beating the Buffalo LinkStation LS720D (80 MBps). The Asustor Lockerstor AS6702T took top honors with 94 MBps.

While the five-bay ioSafe 1520+ was a bit noisy, the 220+ was relatively quiet during testing. It only uses one 92mm cooling fan, while the 1520+ uses two 120mm fans.


The big question: How much is your data worth to you?

You’ll pay top dollar for the ioSafe 220+, but in return you’ll get a two-bay NAS device built like a bank vault. Its specially designed case will protect your data from fire and water damage, and it’s easy to manage thanks to Synology’s user-friendly DSM operating system.

Granted, not everyone needs this kind of disaster protection, but if you want to make sure your data is safe from fire and the water damage that can occur while you’re fighting it, the ioSafe 220+ is your best bet and our latest editors choice. winner for two-bay NAS devices.
