    What can I say, we all know why we consider Synology. They are basically the “Apple” of the NAS space.Positives:-User friendly interface-Robust options for safety nets (notice how I said how it’s not a backup)-A large userbase with many helpful resources to guide through some of the few nuances.-Optional NVME SSD expansion for caching-Optional RAM upgrade-Optional 2x 5 Bay enclosure (should only be used as it’s own, separate volume) for a total of 15 drives of storage.I love the features of BTRFS and SHR1, which are flexible “safety nets” that help protect you from losing all of your data from either a ransomware/crypto attack (BTRFS Snapshots), or a failed drive (SHR1 providing parity data). The advantage of SHR1 vs other RAID configurations is that you are not bound to replacing ALL drives in order to acquire more space. You can simply replace 2 drives with larger capacity drives, to start progressing into more space. These swaps into higher capacity must be done one at a time if using SHR1. Look into Synology RAID calculator if you need more info on how SHR works. Many of the integrations the Synology DSM software brings to the user are also nice (but could be improved on still, such as their Cloud sync application).Negatives:-I wish it had natively faster than 1gb ethernet connections, but it has the option for a 10gb expansion NIC.-If you are looking for a Plex server, this isn’t the one you want, because there isn’t integrated graphics. I believe the best one right now from Synology is the DS920+ but I have no intention of going this route so I did limited research on it.Do I recommend Synology? AbsolutelyDo I recommend this unit? If it suits your needs, absolutely. There are many options, which cater to different users/needs, so take your time and do your homework.I honestly couldn’t be happier so far. If you want to learn more about this unit, I recommend a couple of channels on YT, which I watched for a couple of months leading up to my purchase.SpaceRex and NAScomparesGood luck!———————————————————————————Just to elaborate on some of the features I am using as it pertains to my specific use case, this is not really part of the review, but more so for people interested in knowing how I use my Synology and why.System specs:i9-9900k 5ghz OC32GB DDR4 3200 RAMRTX 2070 SUPER 8GB1x M.2 NVME 2TB2x SSD 2TBDS1522+ with 5x 8TB HGST Ultrastar He8, using BTRFS and a LUN (2TB allocated)I am using it to sync my Photography company’s Dropbox files, create Lr catalog files from the files, and then store our active (not yet approved) client files. The Cloud Sync isn’t as flexible as the Dropbox application in terms of visibility of “Only online” files. Your files can only be syncd as “Available offline” or in other words, stored locally. You do have 3 options of syncing, one way sync (either way) and two way sync. I didn’t like being unable to view my “Only online” files and then choosing to sync them through my windows file explorer like I would have liked. This made me instead create a LUN through DSM, which created a drive that appears as local on my windows file explorer, so that I could set it as a target location for the Dropbox desktop application. My workflow is as follows:-Once dropbox is placed on a LUN, I syncd our entire photography file system to the LUN in Online Only mode. This took a while, since there were about 1.6 million files for just our photos.-I select which clients I want to sync that need to be built into a catalog, and download the files to the Synology LUN-Once they are downloaded, I copy these locally stored files to my M.2 NVME local storage (May not be necessary once I upgrade the Synology to have the 10Gb NIC), import the images to my master catalog file on Lightroom Classic, and build them into a seperate Catalog with Smart Previews.-I assign the catalog + smart previews to an editor by simply copying the zipped smart previews and catalog to the Dropbox folder assigned to the editor.-The editor then begins their edits to the catalog directly from their folder which syncs to me, and if they are not currently working on it with Lightroom running (which I know when they are clocked in or not), I can open the catalog and see their progress or make corrections if they are needing to be made, the next time they clock in, they see the changes I made to it.-Once the catalog is done I pull it from the syncd folder, open my master catalog file, import from another catalog (the one that was just turned in), and then export as JPEG.-Once this is done, I then move all of the RAW image files, off my M.2 NVME drive, to a home folder (accessible on Windows explorer using SMB share) on the Synology, then set the Dropbox files that they originated from, back to Online Only status.-In my master catalog file, I relocate the missing folder that was just moved from my local storage, to the Synology home folder (which is still viewable from Lr), and now I have access to all those RAW files in Lr still, without the need to keep them on my M.2 NVME local drive.-If during review from one of my admins, certain images are needing to be replaced due to a poor cull,I can still pull up the catalog, make the necessary changes, and export as a JPEG while the RAW exist on the Synology SMB Share folder.That is where I am at now.This is where I want go next in due time, and it highlights just a couple features that the Synology offers to improve my workflow efficiency, and save money.Once I upgrade the Synology with the Expansion slot for 10Gb ethernet, and add a PCI NIC for at least 5Gb (maybe I’ll also go 10Gb there too), I may not even need to move anything onto my local NVME, since I will be able to access everything from the Synology at a fast enough speed that I’ll be bottle necked by my CPU rather than the disk read/write. This will need to be tested once I acquire those 2 pieces of hardware.Another improvement I can make, is instead of syncing my editors catalog files and smart previews through Dropbox, I could do it through Synology Drive, which is their version of Dropbox. What’s the advantage? My editors will not require a Dropbox account to be able to use the Dropbox application sync feature. I could save some of them a monthly subscription (or save ourselves that money for the veteran editors on our team), by just using my NAS as the cloud provider for the editors. I have not gone this route yet because I have not yet had the time to research the best way to open my Synology up to the internet in that way. This is one of the few things that (from my understanding) Synology seems to be doing the best with in comparison to other NAS solutions, but it’s a risk that I am not willing to take without educating myself fully on the best approach.Who knows what other optimizations I will discover as I use the Synology more.

    I recently invested in the Synology 2 bay NAS DiskStation DS220+ (Diskless) and it has completely revolutionized the way I handle my digital life. This compact powerhouse has proven to be an indispensable addition to my home network.Setup was a breeze – the DSM (DiskStation Manager) interface is intuitive and user-friendly. Even for someone like me with limited technical expertise, configuring the NAS was straightforward. The DS220+ comes diskless, which allows you to choose the hard drives that best suit your needs. I opted for a pair of WD Red NAS drives for a seamless experience.The performance of this NAS is exceptional. With a capable Intel Celeron processor and 2GB of RAM (expandable up to 6GB), it handles file transfers, backups, and even media streaming effortlessly. I’m able to stream 4K content without a hitch, and file transfers happen at lightning speed.One standout feature for me is the excellent security provided by Synology. The DSM is regularly updated with the latest security patches, and there are robust options for setting up user accounts, access controls, and even VPN capabilities. This ensures that my data is protected from external threats.The DS220+ truly shines when it comes to its app ecosystem. Synology offers a wide range of applications that cater to various needs – from file sharing and backup solutions to media servers and surveillance tools. It’s like having a personal cloud at your fingertips. The integration with third-party services like Google Drive, Dropbox, and more is seamless, making it easy to centralize and manage all my data.Additionally, the Synology community is incredibly active and helpful. The forums and knowledge base have been invaluable in troubleshooting any minor hiccups I encountered along the way.On the downside, it would have been nice if the unit included more RAM out of the box. While 2GB is sufficient for basic operations, power users might benefit from the option to purchase a variant with higher RAM.In conclusion, the Synology 2 bay NAS DiskStation DS220+ (Diskless) is a game-changer for anyone serious about home data management. Its blend of performance, user-friendly interface, robust security features, and extensive app ecosystem make it a standout choice in the NAS market. Whether you’re a casual user or a power user, this NAS is sure to exceed your expectations. Highly recommended!

    Lifechanging. Seriously.I could not love my Synology more.For households with a significant volume of accrued media to access, share, and backup, it is literally lifechanging. In the past I’ve built my own Windows media servers, but this time around I thought I’d give a ‘prebuilt’ NAS solution a go – and Synology is the undisputed gold standard of NAS. This is not just a NAS, it is a fully functional media centre, basckup solution, home security hub, and just about anything else you’d like to use it for.Read up on all the reviews and “how to…” videos, and all the (generally free) plug in software solutions you can install (Plex is a must!), then GET ONE. You won’t regret it.

    Uno de los modelos NAS más recientes de Synology, que funciona de maravilla.Éste NAS tiene buena relación calidad-precio, siendo excelente tanto como unidad de almacenamiento externo, como servidor para acceso y streaming remoto. Adquirí este producto el pasado miércoles 01 de Julio de 2020, comparto que me llegó rápido y bien empacado el día 10 del mismo mes y, puedo decir que: para un usuario que va a respaldar información de sus computadoras y dispositivos móviles, almacenar fotos, música, video y COMPARTIRLO tanto en una RED LOCAL (casa, pequeño negocio) como acceder a él desde una red remota sobre todo para trabajar con la información almacenada y usar archivos de medios usando Internet, resulta excelente sobre todo para usuarios hogareños, pequeños y hasta medianos negocios para atender hasta 320 usuarios.A FAVOR:+ Fácil es la instalación física y una configuración básica sólo si se va a usar y compartir en una LAN; ya una configuración más avanzada sí requiere conocimientos de redes y sobre todo de seguridad informática, si se piensa usar como servidor conectado siempre a Internet.+ Si se conecta a red local (LAN) de 1 gigabit, con cable UTP nivel 7 y con un switch de gama alta, puede alcanzarse buena velocidad de transferencia, en mi caso pude pasar 750 Gigabytes en casi una hora (55 minutos).+ Como servidor de archivos tiene buena seguridad al gestionar a los usuarios, sus contraseñas, permisos de acceso local o remoto tanto de forma individual como en grupo, así como designar (si se desea) una cierta cantidad máxima de espacio. También permite asignar varios niveles de permisos por aplicación, grupo de directorios, carpetas individuales y hasta por archivo.+ El costo de esta unidad NAS, SÍ desquita por las características de hardware y las aplicaciones que se le pueden instalar. El fabricante Synology proporciona varias aplicaciones muy buenas, para sacar el mayor provecho posible. Entre las más importantes:- Hyper Backup permite tener sincronizado el cotenido de las computadoras conectadas en la red local (LAN) con este dispositivo de almacenamiento;- DS-Audio para escuchar tu colección de música tanto local como remotamente;- Moments, para guardar y compartir todas tus fotos escaneadas, digitales, respalda bien las fotos y videos de smartphones y tabletas; en mi caso en una Smart-TV pude ver fotos en varios formatos;- VideoStation para hacer “streaming” de videos caseros tomados con “HandyCam” en formato MTS, MP4 o tu colección de películas (soporta MKV), igual de forma local (puedes conectar varias “Smar-TV” a tu LAN y ver las películas almacenadas), así como desde internet usando la aplicación DS-Video;- Servidor DHCP para gestión de red LAN;- Servidor DNS para dominios;- Servidor Web HTML “Apache” o “NGINX”- También se puede instalar servidor de PHP desde la versión 7.1 a la 8.0.17), con la posibilidad de hospedar varios sitios web simultáneamente (se pueden instalar gestores de contenido como “Joomla” o “WordPress”), así como blogs;- Servidor de bases de datos “MariaDB-10” (totalmente compatible con MySQL);- Gestor de bases de datos “phpMyAdmin”;- Surveillance Station para conectar y gestionar videocámaras de tipo IP, grabar y reproducir visualizando directamente lo registrado por ellas a través del explorador Web, VisualStation o dispositivo móvil para supervisión remota;- SMB Service para uso compartido de archivos y carpetas en una red LAN, así los usuarios de Windows, macOS y Linux, pueden acceder a ellos estando almacenados en este NAS;- Servidor VPN para conexión remota desde varios dispositivos (yo lo uso con OpenVPN);- Servidor FTP para subir y descargar archivos;- Servidor WebDAV también para conexión, gestión remota y trabajar con los archivos almacenados en éste NAS … y otras aplicaciones de terceros: multimedia (Plex), descarga de archivos (Mega), de productividad, para trabajo de oficina y en grupo; también se puede tener tu propio servidor de correo electrónico.EN CONTRA:+ Lo único en contra o “malo” y, creo NO es un problema exclusivo de este modelo NAS de Synology, es cuando haces “respaldo de los respaldos”, es decir, cuando se hace una copia de seguridad de TODO lo almacenado en un NAS de Synology usado para realizar a su vez respaldos de la información contenida en Laptops, PC’s, MAC’s, smartphones, tabletas, etc., al usar la aplicación HyperBackup que considero es lenta para realizar respaldos de volúmenes (arreglos de discos) completos. Para alguien obsesivo que desee tener “respaldo de los respaldos” al resguardar TODOS los datos almacenados en un NAS de ésta marca, es necesario que tenga mucha paciencia, sobre todo si tiene más de 8 terabytes en información.CONCLUSIÓN:Fuera de lo lento al respaldar completamente volúmenes en arreglos RAID, TODO lo demás me parece excelente. Conectado tanto en red local como en acceso remoto fuera de donde lo conecté, funciona de maravilla (yo recomiendo una conexión a Internet simétrica); me ha resultado excelente para almacenar toda mi información valiosa (espero no falle pronto). Cuando termine su periodo de vida útil, voy a comprar otro dispositivo similar de Synology.¡Gracias por su atención!

    Came With EU not UK Power LeadI brought this to replace my old DS415play. Although it is easy to install due to being provided only with a lead with a Schuko (EU) plug and not one with (or as well as one with) a UK plug I have taken of a couple of points for ease of installation. Fortunately I had a spare kettle lead fitted with a UK plug (all I need to do is change the fuse down from the fitted 13A to a 3A).The drive installation was easy however not toolless as I was using 2.5″ drives and as such needed a screw driver. The toolless installation only works for 3.5″ drives. Once installed, plugged in and connected to my switch it appeared on my network and I was able to use the web interface straight away to to the initial software download and copy the configuration stored with Synology from my old NAS. It populated my folder structure on the RAID volume and my user accounts. This configuration backup is probably only of real use for a bussiness setup when there are multiple user accounts.
