Fast rack based Synology server—nice build quality.
An upgrade on an older '+' style Synology box. The previous physical drives transferred over fine and the new PAT rebuilt the DSM without too much hassle. I forgot to delete the Bond setting from the previous Synology box (before backing it up) and thought I'd have to fry the DSM on the RS1221+ in order to clear that setting (moving from 2 ports bonded to 4 ports bonded) but I managed to use the reset and force it to delete and reconfigure. Only one Cat 5 could be plugged in while achieving this reset—not all four—once realised easily fixed. The password reset method isn't well described but otherwise everything is fine. Still running the drives back in on the new box without upgrading the RAM (32GB) or network connection (10Gb). It's nicely built, not over the top, and fits well into the rack. The fan noise has increased considerably over the smaller Synology boxes but not quite as loud as a dedicated server build (though this is only a quarter of the size). A two bay Synology is whisper quiet, a 5 bay had some fan noise but can be drowned out by drive chatter, this 8 bay unit has real fan noise (on it's lowest, 'quiet' setting) and has a presence in the office. Destined for a cupboard anyway but I'd suggest planning for isolation if you like peace and quiet. My last Synology box lasted for over 10 years without any huge issues but doesn't match this for pace of file delivery, build quality (much more metal involved) or simple storage capacity. It doesn't present the fastest preview yet (for really big files) but with plenty of upgrades to come it has the legs to be a powerful performer in a small form factor. It came double boxed and is well protected for transportation. It's a nice unit for those who just need things to work; have large storage needs; don't like constantly rebuilding backup solutions or having multiple drives rolling around. The Synology DSM has many reviews elsewhere. Thumbs up.

Solid system despite all the recent Synology drawbacks.
Solid performance. This is the first rack mount Synology I’ve owned everything else has been desktop (we have three 8 bay desktop NAS as well). This is excellent, although much louder than our desktops but it does have redundant power supply and a smaller form factor so to be expected.

Great home NAS
Bought as a replacement for a home theater pc that was also a gaming PC. The ability to run PLEX as an installed app directly from the NAS is great as well. There was some networking that needed to be setup to provide access from outside the local network but there's enough kb articles online to get it done. I've had no problems with performance (compute or network) on my home network. User interface is great for the price and updates are easily installed so no IT background is required, just simple smarts.

Feature Packed Value
Finally pulled the trigger and bought a NAS, synology has many useful features I was looking for - efficient use of the drives, monitoring and utilities, easy and quick upgrading and management of storage pools, UPS integration, ability to run Plex and other server types, replication, SSD caching, and more. The only downside is the loudness of the fans, if this is in the same room as you are. Fans are replaceable with quiet versions, then it’s very quiet. These are designed for server rooms, so noise isn’t a focus for this model understandably. I can see why these are so popular.

Glad I upgraded!
So first off I know Synology has gotten a lot of flack because of vendor locking hard drives to their hard drives. But I can confirm you can use third party hard drives (I'm using Seagate) and still get all the full benefits without any weird hacky stuff that was posted on the Linus tech forms. Synology has updated their supported drives list and the hard drives that I purchased work perfectly fine. Secondly, I'm upgrading from a 11+ year-old DS1511+, which has served me well over the years but I was maxing out the amount of hard drive space I could actually put in that device. This is a worthy upgrade. The sucker is blazing fast, it's quiet, and temperature wise. The added bonus is is it goes to my server rack so it looks really nice. The only reason why I'm not giving this five stars is because I attempted to run jellyfin on this device and it does not run well at all, so I'm still using my personal computer as my media server which references all the media data on my Synology device.

As a basic NAS / RAID device, it is great. But the RAM is too limited to take advantage of all its software features.

業務用途として RS1221+ を購入しました。通常運用では性能も十分で、筐体の作りもしっかりしており、DSM の使い勝手も良好でした。この段階では特に不満はありませんでした。 問題は、DSM の定例アップデート後の再起動で突然まったく起動しなくなったことです。電源ボタンを押しても反応がなく、LED もファンも一切動作せず、完全に沈黙しました。ハードウェア故障自体はあり得るとしても、その後のサポート対応でより深刻な問題が明らかになりました。 Synology も、正規代理店である 株式会社フィールド・レイク も、先出し交換(Advanced Replacement)を日本では一切提供していません。ビジネス用途であっても例外はなく、保証金や本人確認などを提示しても不可能との回答でした。その後の案内でも フィールド・レイク から「日本では先出し交換の仕組みがそもそも存在しない」と明言されました。 唯一の対応方法は「故障品を先に送り、台湾から届く代替機を代理店経由で受け取る」方式だけです。 ユーザーが故障機を フィールド・レイク に送付し、代理店が台湾から代替機を受け取り、それをユーザーに再発送する流れです。どれだけ急いでも数日〜数週間かかります。 業務用途でこの対応は現実的ではありません。北米や欧州で提供されているようなビジネス継続性を前提としたサポートは、日本には用意されていません。つまり、製品は「ビジネス向け」として販売されている一方で、故障した瞬間にサポート体制は完全に「家庭向け」レベルになります。ダウンタイムを抑える手段が存在せず、業務継続という観点では非常に脆弱です。 RS1221+ は正常に動いている間は問題なく使えます。しかし一度故障すると、日本国内のサポート体制では業務継続がほぼ不可能になります。Synology が日本でも本当にビジネス用途を想定するのであれば、サポート体制の抜本的な改善が必要です。 家庭用途やメディア保存用途であれば問題ありません(ラックマウントとしてはやや特殊ですが)。 しかし、業務用途、特にダウンタイムが許されない環境では適した製品ではありません。
