同じメーカーの方が良いかな?と コンパクト面でSSDも考えましたがお値段でこちらを選びました
とにかく設置が簡単 コンセントさして電源入れたら後は流れに沿って終了
今までと同じ画面表示で問題なく使えてます
音が静かなのに驚いた(今までのがうるさかったのか)
日常的に使うとHDDの寿命は5年くらいなので、そのあたりでデータを乗せ換えるのにちょうどよい品。
不具合無しです。
音もほとんどせず、HDDなので巨大なデータだとSSDに比べ多少時間がかかりますが、それほど速度も気になりません。
ただ縦置きの場合は幅が狭いため安定が良いとはいえず、縦置き用のサポートホルダーみたいなものが付属していればと思いました。
また基本的にTV録画用で繋ぎっぱなしを前提にしているためか電源スイッチがありません。まあ使用するときだけアダプタを挿すか、スイッチ付きタップで対応すればいいのですが、電源スイッチぐらい付けておいてくれても良いのになと思います。
使いやすい思います。
