One big issue

Reviewed in Canada on 9 February 2021

For video media, you have 2 options. Video Station and Plex.
There is a now new codex (x265 and DTS for audio) that is popular.
Video Station does not play it and suggests you download software to convert these files to using a different/lesser format that Video Station will play, which is a pain in the ass.

Plex will play it, but not for free.

Other Video player options that appear to be available in other, perhaps older Synology devices (Emby & Jellyfin) are not available to be downloaded and used on this device.

If this is important to you and you have some technical skill (or are willing to learn), you are better off buying a tower with slots for 4 hard drives and installing FreeNas on it. You will get a much better machine (with way more than 1 GB of Ram) and more choices for software.

Excelente solución

Me encanto este NAS. He tenido otro de otra marca y la verdad nada que ver con este Synology. Extremada fácil de usar, todas las aplicaciones gratuitas dan una solución excelente. Lo uso principalmente para nube personal y trabaja excelente de donde me encuentre, oficina o de viaje. Se los recomiendo para uso personal y pequeños negocios sin dudarlo.

自宅NAS初級者向けの割に高機能。
但し、HDDの診断やパリティチェックに数日掛かることが難点。
買う前に構築時間が長く掛かる覚悟が必要だった。

ストレージサーバとしては充分

Reviewed in Japan on 1 March 2021

Verified Purchase

センチュリー製のESATA外付け5台BOXが挙動不審になってきたのでこの機会に買換え。
とりあえず今引越し中ですが、引っ越した内容も再生したりしたので報告まで。
手違いで購入したAsustorのAS1004T v2と比べて評価していきます。
使用したHDDはこちらで買った東芝制NAS用10TBです。
1.説明書
どっちもぺらぺらですが、いいたいことは伝わるので問題ありません。

2.HDD組み付け
ASは全体がスプリングワッシャ付きネジで、DSは単純なネジです。
スプリングワッシャ付きは振動の多いところで強みを発揮しますからHDDの取り付けネジとしては最適ですね。

3.初期化(RAID5)
ASは概ね14時間くらいで終了しました。
DSは30時間位かかりました。
ただし、ASは16TBしか確保していない(出来ない)ので同じくらいでしょうか。

4.Windows用ネットワークドライブとして追加
どちらも単純に繋がります。強いて言えばネットワークログインする時にNAS側のユーザ名がWindows側に無いとログインできません、つまりネットワークドライブとして連結できません。Windowsに詳しくない方はここだけ気をつけて。

5.ファイル移動
ASは16Tの壁で心が折れたのでしていません。
DSはブラウザ画面からのコピーとNTエクスプローラでの移動を試しましたが、ブラウザ画面からの移動は行っても80、NTエクスプローラからだと100がコンスタンスに出ています。ちなみにNTエクスプローラで追加でファイル移動させると、最初は100のままで次も50が出ます。何の限界なんでしょうね。

6.動画再生・書類閲覧
特に引っかかる事も無く問題ありません。

7.騒音
既存のレビューではうるさいとか色々な事が両機種とも書き込まれていますが、デスクトップPCが近くにあればコピー中でも音は聞こえません。

8.その他
特に公開サーバなどの予定は無いので、外部からのアクセスはすべてシャットアウトさせています。
ちなみにDSの青LEDは設定をしないと電気を消した室内ではこうこうと光っており、目に入る位置にあると寝れません。LEDの明るさを落すことができるようなので落としましょう。
更に青色LEDというのはネコの蚤を呼び寄せる色ですので、NASの下に協力粘着シートを置いておけば、寝てる間に蚤も駆除も出来ますので、犬猫を室内で買われている方は是非お試しを。(ただ真っ暗な中で青色LEDが時々遮られるとそれはそれで異様に痒くなりますが)

3/3追記
ファイルネーム制限がWindowsと違うところがあるので、".4-1.CUE"の様な小数点が先頭に来るファイルや、長すぎるファイル名はコピーが出来ないので注意。
