It's a tip I get in a daily email message, it's not the gospel according to list management. David Ferrin [email protected] ----- Original Message ----- From: "Nimer Jaber" <[email protected]> To: <[email protected]> Sent: Saturday, August 07, 2010 10:00 AM Subject: Re: [Blind-Computing] daily tip
Hello Rick, I'm not disputing that there are notebooks with data cables, I'm only disputing the claim that states most notebooks use data cables because most computers I've seen in the past few years are using SATA drives, and I'm not disputing that faster speeds can be obtained for the most part by paying for more expensive drives, only saying that most notebooks come with 5400 or 7200 RPM drives and most of those are 5400 unless they're certain brands or they're Macs. I realize that drives can be upgraded and that there are some comps with IDE drives, I'm just pointing out that this article's specs don't match up with most notebooks, or rather the notebooks I've laid my hands on. Like I said, I could be missing something.
