All the cables you copy are the same, right?

I used to think so too.

A USB-C cable from a 100-yen shop is enough.

But one day I realized.

( For some reason, the new 7,000 MB / s SSD only comes out at 380 MB / s. )

The cause was the 100 yen cable.

The moment I changed to a certified cable, it jumped to 1,180 MB / s.

3.1 times the difference.

At that time, I calculated.

In my case, I transfer 200GB of data three times a day...

100 yen cable: 1 time 8 minutes 47 seconds x 3 times x 240 days = 105 hours

Certification cable: 1 time 2 minutes 50 seconds x 3 times x 240 days = 34 hours

Deducted for 71 hours. If the hourly wage is 3,000 yen, the annual loss is 213,000 yen.

It's not just the cable.

How to choose storage, understand interface, OS setting, cooling measures...

It was like throwing away money every day just because I didn't know.

But if you have the right knowledge, you can get it back quickly.

With the knowledge I have gained over 25 years of experience,

All were systematized with actual measurement data and calculation formulas.

If you understand the essence of technology,

Even if a new standard comes out in five years, you will be able to make your own judgments.

That 100 yen cable is still in the drawer.

Do not forget the value of correct knowledge.

How many hours are you waiting for today?

... Read more私も以前は、どのUSB-Cケーブルも同じだと思い込んでいました。しかし、実際に高速なSSDを使い始めて初めてケーブルの品質の差を痛感しました。特に7,000MB/sの性能を備えたSSDに100円のケーブルを使うと、なぜか380MB/sしか出ないという大幅な速度低下が起こります。これは単なるケーブルの品質だけでなく、USB規格や認証の有無などが影響していることに気づいたのです。 認証済みケーブルへの交換で速度が1,180MB/sに上がり、3倍以上のパフォーマンスを引き出せるのは驚きでした。この差は日々の業務において時間を無駄にするだけでなく、作業効率や収益にも直結します。私のように大容量の200GBファイルを1日に数回転送する場合、無駄になる時間は年間で70時間以上。これは時給換算で20万円以上の損失に相当します。 また、USB-Cケーブル以外にもストレージ装置の選び方や接続インターフェースの理解、OSの設定や冷却対策など様々な要素がパフォーマンスに影響を及ぼすことを知りました。これらの技術的な本質を理解し、正しい知識を身につけることが結果的に長期的なコスト削減と作業効率向上につながります。 私自身、25年以上の現場経験から得た知見を元に実測データを収集・分析し、ファイル転送の合理的な方法を体系化しています。技術の本質を理解すれば、新たな規格が出たとしても自分で適切に判断できる力が身につくため、投資回収期間も短縮可能です。 そして、思い出としてあの100円ケーブルは今でも机の引き出しに置いてあります。「正しい知識の価値」を忘れないために。もしまだ速度改善の手段を知らないなら、今日からケーブル選びとストレージ設定を見直してみてはいかがでしょうか?その積み重ねが大きな時間とお金の節約になります。
