Synology DiskStation DS218 External HDD Overview

This B&H Kit combines the Synology DiskStation DS218 2-Bay NAS Enclosure with two Seagate 8TB IronWolf 7200 rpm SATA III 3.5" hard drives for a total storage capacity of 16TB.

Synology DiskStation DS218 2-Bay NAS Enclosure

Designed for small offices and home users, the DiskStation DS218 2-Bay NAS Enclosure from Synology allows users to share and synchronize files across multiple devices and public cloud storage services from virtually anywhere, while also helping to boost work productivity, enhance team collaboration, and engage in real-time 4K H.265 video transcoding. It is equipped with two drive bays that are capable of natively supporting 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs. Using its dual drive bays, this NAS will allow you to store and share a large number of files, including videos, music, photos, and documents with up to 2048 user accounts.

The DS218 runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system which helps to simplify managing your Synology NAS. Its CPU is a 1.4 GHz Realtek RTD1296 Quad-Core, and its 2GB of DDR4 RAM allows frequently-used files and applications to be quickly accessed. The NAS is capable of achieving sequential read and write speeds of up to 112 MB/s, while a dedicated hardware transcoding engine can transcode 10-bit 4K H.265 video on-the-fly. Also featured are two USB 3.0 Type-A ports and one USB 2.0 Type-A port, which allow it to be connected to your Windows or Mac system, and network connectivity is achieved via the integrated Gigabit Ethernet port, allowing your stored data to be shared with users throughout the network. Data may also be made remotely available through the free iOS and Android applications. Using the integrated 4K multimedia server on the DS218, Video Station and DS video can be used to convert and play 4K videos from most computers, mobile devices and other media players that don't support Ultra HD formats.

For those who require RAID support, the DS218 supports RAID 0 and 1, as well Synology Hybrid RAID and Basic RAID, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

The DS218 is engineered to be energy efficient. Not only does it offer a 92 x 92mm fan to help keep the system running cool at all times, its noise dampening design of 19.3 dB(A) makes for quiet operations. The server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimize power consumption and operation expenses.

The Synology DiskStation DS218 2-Bay NAS Enclosure operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, a 60W AC power adapter, a power cord, and an RJ45 LAN cable. It is protected by a limited 2-year warranty.

Synology DiskStation DS218 External HDD Reviews

Not what I needed, but a great value bundle

I ended up getting the DS720+ but kept the two drives. I'm not sure what to do with the enclosure for this now, but it was a great deal.

My New NAS Upgrade

By Mark
Rated 4 out of 5
Date: 2021-08-07

Purchased the Synology Diskstation DS218 kit with two WD Red Plus NAS drives to replace a pair of aging consumer level single drive network drives from another brand. I chose the DS218 over the newer and more powerful DS220+ as I wanted the additional USB port for use with a UPS while retaining the ability to connect a backup drive at the rear. I did not feel I needed the redundant LAN connection and while the Celeron processor would have been nice I do not anticipate needing the processing power. I am liking the benefits of the Raid 1 configuration and the recycle bin not provided by my previous boxes. Initial setup was straight forward as far as getting the DS218 up and running. After that it can be a bit overwhelming as there are many options available in settings that were not offered in my earlier home user oriented drives. Fortunately, there is a lot of information and advise available through Synology and other internet sources. Liking the recycle bin, snapshots, and other features that were lacking in my old setup.

What a pleasure to have this unit

By Robert

I have tried FreeNAS and other means of having a systematic backup at home as well as file sharing from home but I didn't have success and I am not tech savvy. While the automatic backup through the USB external Drive setup did require a help of a friend I am able to use the new unit as my home cloud and backup system successfully. Even though I needed some technical help of a friend I am still giving a 5star because the product seems to be of a good quality and very feature rich at a price I couldn't find anywhere else.

Faster than my old Seagate GoFlex NAS

By Armando
Rated 5 out of 5
Date: 2020-09-04

I had my GoFlex NAS for several years now and somehow its software can not keep up with Mac software updates. This is my first time using Synology DiskStation. Besides noticing faster file transfer, this system offers lots of features and good Control Panel interface. The default setting is Raid 1 - disk mirroring for redundancy. I am very happy with my purchase. I just hope this will last for a long time like the reliable GoFlex. Thanks Synology and B&H.

I was looking for a personal cloud so that my kids' pictures wouldn't end up on Google, Amazon, Facebook, or Apple servers, and was worried this would be too advanced for me. But it didn't take much YouTube to be able to use great features this provides. And I feel like the more I learn, the more I will be able to use it. All in all, great purchase for home backup and personal cloud usage for us! Also, love the Moments app for pictures!

The perfect solution for large image, music & video files

By Timothy
Rated 5 out of 5
Date: 2022-03-13

I'm a photographer. When I order a new MacBook Pro M1 Max in October, I purchased the Synology 24TB DS218 NAS for less than upgrading the MacBook from a 1TB SSD to a 6TB SSD, and a third less than upgrading to an 8TB SSD. The Synology software made it quick and easy to configure the NAS, and when I attached USB drives to the NAS enclosure, transferring large amounts of files to the 24TB NAS through the Synology desktop was very fast. So now I have years of photo files, music files, and video files all in one place that I can access from multiple computers. I recently ordered a Synology DS220+ NAS from B&H that I'm using to back up the 24TB DS218 NAS.

Great replacement for WD MyCloud

By Ronald
Rated 5 out of 5
Date: 2021-12-27

I bought this DiskStation to replace an aging Western Digital MyCloud device. I wanted a unit that supported RAID 1 disk duplication and allowed for future disk upgrades to a larger capacity. This unit nicely met those requirements. Installing the hard drives in the DiskStation was easy, I just followed the diagrams in the instructions. The instructions then gave me a link to a web address where I registered the product and downloaded the disk management system. The system installed and then formatted the hard drives. I opted to do a disk check as part of the formatting, so I let it run overnight. Next day it was finished and ready to go. I use this device to store system backups from six different PCs over my home network. I was able to modify my existing backup scripts to point to the new device. I was also able to copy files from my old device to the new one over the network. So far it has worked flawlessly. It is quiet and I like that it spins down the disks when they have been inactive for a period of time. As an added bonus, it backs up my systems faster than the old device did.
