Thanks for the advice (and numbers). I do have a slot and may follow |
| 24 |
your suggestion. My only reluctance is that the disk gets such light |
| 25 |
usage that I don't notice its slowdown compared to my internal faster |
| 26 |
disk. So I have pause if opening the case is justified. |

But again, thanks for your helpful msg. |
