If you can stomach the up-front cost, buy a Synology. The convenience and ease of use are well worth the price. You could build a more powerful NAS yourself for less money, but it would use more power, take up more space, and (most importantly) require more time/hassle to manage.My previous setup was a Mac mini with some USB attached storage. That worked mostly great for about 9 years, and I was looking to update the setup and thought I'd give some proper NAS options a look. I have always been put off by the relatively high prices of NAS devices, particularly Synology ones, but after reading about all the built-in features I took the plunge and gave the Synology DS1621+ a try. I'm glad I did!This device has a fantastic array of features, most of which I don't really need, but the ones that I use work very well and (just as importantly) were extremely simple to set up. Here are some thoughts on the things I'm using so far:Synology Hybrid Raid (SHR): I'm using SHR-2 for double redundancy and it was painless to set up. I love that I can pop in another drive later on and expand the pool without any trouble. It also supports checksum validation and correction with the "Data Scrubbing" feature if you're using the default BTRFS file system, so I've set that to run monthly to avoid bit-rot. I don't have enough experience with this yet to say how it works in practice, but in principle this is great.Shared folders: this is the bread and butter for a NAS, and it was extremely easy to setup and configure with Synology DSM. It works SO much better than the shared drives on my old Mac mini because it handles permissions properly and everything "just works".Time machine backup: this is essentially an extension of the shared folders, with one extra configuration required to make the folder appear as a native network time machine backup destination. Worked seamlessly for configuring backups for a few Macs.Docker containers: I migrated all my docker containers which were previously running on Docker Desktop on the Mac mini to the Synology and they work much better than they did on the Mac. They are faster running and simple to manage with a decent built-in UI. I'd have preferred built-in Docker Compose support, hopefully that'll come in the future, but for my use case configuring via the UI was OK.Application portal / reverse proxy: I love this feature, it makes routing requests to various services super easy. I'm comfortable configuring nginx by hand or via automation, but for home use I prefer a simple UI like Synology provides. You can assign certificates to routes, and everything works great with my custom domain.Certificates: I has high hopes for the built-in Let's Encrypt support, but unfortunately it requires the server to be exposed to the internet (no thanks). Hopefully in the future they support the DNS challenge option, but for now the easy way to solve this is to use the open source acme.sh which has support for tons of DNS providers and has built-in hooks to register certificates with Synology's UI. I have acme.sh running with Synology's Task Scheduler and it works great.VPN Server: supports L2TP/IPSec so you can use the built-in VPN for iPhone / Mac, no third party apps required on your devices. This is the only thing I have exposed to the internet, and in my testing it has worked right out of the box with very minimal configuration needed.Other thoughts:- Synology Chat: Slack knockoff, works better than I expected honestly! I disabled this because I don't fully trust the security of this app for exposing it to the internet.- Hyper Backup: haven't fully configured this yet, but seems to support a good selection of services- File Station: really nice web-based file browser which you can access via the admin UI, or as a standalone web UIThere are so many more features that I haven't even begun to explore, like the built-in Plex support, but I can say so far this NAS has exceeded my expectations and I expect that I'll keep finding new useful features as I keep digging and configuring.On the hardware front, I did a couple upgrades:- 32GB ram: https://smile.amazon.com/gp/product/B0899KV2L5/- Synology 10Gbps ethernet adapter: https://smile.amazon.com/gp/product/B07G9N9KJT/I'm using two Seagate IronWolf 8TB drives and two WD Red Plus 8TB drives so far and both work well. The Seagate drives have some extra diagnostic information available due to a special built-in integration with IronWolf drives that is very neat. Unfortunately the WD Red Plus drives say they are unverified because Synology hasn't added them to the official list of verified drives for the DS1621+, but I bet that was an oversight because the WD Red Plus drives are listed as officially verified with pretty much every other Synology NAS. Doesn't make any difference in practice.Despite the high all-in cost, I'm completely satisfied with my purchase and expect that it'll last me a long time.

Todo de buena calidad, muy bien empacado y con todas las funciones prometidas y más.Lo recomiendo ampliamente.

El producto cumple completamente mi expectativa de acuerdo a los descrito, con excelente soporte y gran variedad de aplicaciones. Pero lo mejor es que lo encontré en excelente precio en Amazon, incluso más barato que modelos inferiores (4 bahias, 4 Gb, DS+) y comparado a otros vendedores en línea.

I purchased this DS1520+ as a diskless system. I also purchased Ironwolf drives along with it and later followed up with an Ironwolf M.2 cache card that I installed a few days later.Setup was simple and fast. Install the drives, let it format and run it's integrity check. While the check is running, you can use it. I come from a much older NAS, a ReadyNAS NV+, that was definitely showing its age, but served well for over a decade.1. It's quiet. I assume a lot of this to do with the drives, but the ones I chose and this unit are whisper quiet. It sits less then 3 feet away on my desk, and the most noise it makes is a barely perceptible rumbling noise when the disk access is heavy.2. It's fast. Compared to my old system, it's probably 10X faster on file transfers. Yes, it's noticeable that it's not a local disk, but I cannot complain at all about the speed.3. Easy to setup and use. A basic install of disks and initial setup of the DSM software on it is pretty easy to manage - and it's a tool less install too. For setup, you can dig into it and make it much more complex, but setting up a plex server was simple enough and docker - well that depends on what you are installing. Only warning I have here is be careful how you set up networking. They have a tool that does a security check that warns you of potential problems, but you do not want to expose it unnecessarily to the Internet.4. SSD Cache helps. It learns eventually what files are most accessed. It's useless for streaming movies - the disks are adequate enough for that - but the metadata comes quickly off the system. Make sure to tell it in the SSD configuration to stream large files off the disks to preserve cache space. I installed this about a week after getting the unit. Since I only have one M.2 card, the cache is for NAS reads only - you'll need two cards for a read-write cache. Turn it off, flip it over and plug it in. Flip it over and turn it on again. Then tell it you want to set it up a SSD and a few clicks later, it's done.5. Plex: Runs like a champ on this system. I use it to stream media to iOS devices and the AppleTV.The only complaint I have is that perhaps I should have ordered larger drives to put in it, but that's on me. 2 drive fault tolerance takes huge chunk out of your storage space. After migrating all my data, it was about 40% full. That's about 10+ years or so worth of accumulated data, so it may not be that bad.My setup:Synology DS1520+ w/stock 8GB RAM5x Seagate Ironwolf 4TB drives, formatted SHR w/2 drive fault tolerance. 3.64TB (formatted space) x5 = 18.2TB, 10.9TB useable for storage.Seagate Ironwolf 480GB M.2 cache card.

Synology für mich erste Wahl. Danach würde QNAP folgen, dann die anderen. Warum 5 Bay? Wer nicht gerade 8 TB Datenvolumen braucht, kann sich hier viel Ausfallsicherheit gönnen inklusive Hotspare (Spring von alleine ein, wenn Platte defekt ist). Über die Apps habe ich eine DSM im Docker laufen. Die Rechenpower der Synology reicht locker aus.Ja, mit den Platten zusammen (habe auch die SSD Ramerweiterung) zusammen fast 2T€ aber jetzt für die nächsten Jahre Ruhe und die Daten sind sicher. Da dies mein wichtigster Punt war, läuft jede Nacht noch eine Vollsicherung (Hyperbackup) auf eine an das Synology angeschlossene USB3-Festplatte. Diese ist nur der Synology selbst sichtbar. Ein Verschlüsselungstrojaner könnte die Datensicherung also nicht erreichen...

ME-gusto el ahorro de espacio para acomodarlo en partes pequennias, y no me gusto que no sea compatible con opciones de Virtualizacion en puertos de ROuter a LAN desde internet. y el poco soporte de apps para el mismo.

This NAS drive is awesome. The admin interface is easy to use. The device is very powerful and has massive storage capacity. I'm using it as a media server for movies, TV shows, and music (Emby) and e-books (Calibre).Installing the Emby media software was pretty straightforward. Getting the Calibre e-book manager set up was a little more complicated because I had to install the Docker container application first, then install and configure Calibre. Fortunately there are online tutorials that help with the installation and setup.I've currently got six 12 TB drives in the Synology, so I can double my storage by adding more drives. And if that's not enough there's an expansion unit that adds another 12 bays! But my first upgrade is going to be adding more memory.I set up a smaller media server for my daughter in law, using a Synology DS218+ with two 4 TB drives.If you're looking for a NAS with brains enough to do almost anything, you can't go wrong with Synology.

Muy buena compra, tiene muchas más funciones a las esperadas. Excelente para usar con Plex y como sitio de almacenamiento en la nube.

This is a robust enough NAS to be able to stream from Plex, record TV shows with a HD Homerun tuner, make backups of servers and desktops and general all around use.As a Plex Server, this NAS does a great job. It has no issues streaming 1080p, recording TV shows or watching live TV with a Plex Pass.Synology keeps its OS up to date with security fixes and feature updates.The Synology Surveillance Station is great if you have generic video surveillance cameras, like Amcrest, Reolink and others. I have been using this feature for years and purchased the licenses to use more cameras at once.The 5 bays give you ample space. I have 5 x 10 TB WD RED drives and with RAID, it gives me 35 TB of formatted space.The Virtual Machine Manager works, but it isolates me from the raw drive images, so I prefer how QNAP easily exposes the drive images their version, primarily for backup purposes. For VM's, in my opinion, QNAP is a better choice.The iSCSI feature works well.This one comes with an external power brick, which I like better than some previous versions of 5 bay Synology NAS'.Technically, you can upgrade it to 16 GB of RAM if needed for virtual machines. Synology doesn't support it, but it works.Depending on your needs, both the DS1019+ (5 bay) and DS718+ (2 bay) are great NAS' and easily recommend them.

He tenido varias NAS Synology y esta es de las mejores. No es de rack, es de desktop, pero funciona excelente para el hogar y la empresa. Tiene 8 slots para 8 discos y soporta raid 0, 1, 5, 6 y 10. Tiene un CPU muy bueno por lo que la uso para PLEX y NVR sin mayor problema (6 cámaras). EL video no se pone lento, carga rápido y tiene 4 conexiones de red. Es silenciosa pues los ventiladores son enormes. El software de Synology es el mejor, fácil de usar y libre de problemas. Este modelo tiene mucho software para instalarle y ejecutarlo sin mayor problema. Synology siempre recomendado y este modelo es de verdad calidad premium por sus funciones.

Muy buena compra y con 5 discos de 12Tb trabaja muy bien, el S.O. de Synology es muy bueno y con muchas características.

Lo recomiendo, yo lo compre para guardar las fotos que se van tomando de la familia, pero despues vi que tiene diferentes cosas que puede hacer, ademas si compras la cuenta flex le puedes sacar mas provecho, ami me hace falta aprender a usarlo para poder sacarle provecho. Necesito ver donde puedo aprender.

muy buen producto
