O.T. eBay malware/virus?
Unfortunately the 780 doesn't have a
second SATA power cable(the smaller of the two) so I can only test one HD at a time and then have to move to cable to the other HD to test it. Here's the HDTune for the 750GB HD: http://i63.tinypic.com/213j21w.jpg Robert |

Robert The sustained speed is faster on the 2TB and the Access time (seek) is slightly lower on the new drive (lower is better). Normally, all the 7200 RPM drives cluster pretty close on Access time (12-16msec or so). The fastest hard drive I've seen advertised so far, is a 15K drive (so half the access time) with a 300MB/sec sustained transfer rate. But drives like that tend to be noisy, so you wouldn't like it. There was one of those 15K drives that made a screeching sound, and the claim was, "that was normal". The fastest solid state drive, is one of the NVMe ones which works at 2500MB/sec. To boot from those requires BIOS support, so just buying an adapter card to fit one isn't enough. They can work as a data drive without a problem, but if you want a boot OS on it, the BIOS needs a read routine to boot from it. I don't know when, if ever, I'll get one of those. The wiring on those goes at close to 4000MB/sec, but the chipset buffers hold them back a bit. And being Windows, of course you don't get the feeling of speed that you should. You could get an SSD with 400MB/sec transfer speed for around $22, and it might be just big enough to install Windows 7 on it. But it wouldn't have the space to hold any backups. That's a SATA SSD in a 2.5" formfactor. Paul |

If the tower has an optical drive, you can "borrow" the power and data cables and use them for a hard drive. It all depends on the available cable length, how they're dressed, as to whether they could be re-purposed to allow testing two hard drives at once. Paul |

Paul Even if they aren't long enough, unless they're _very_ short and also awkwardly placed, you can use them, with the backup drive just hanging, or supported by an elastic band, cable tie, or whatever - unless you're backing up every day. That's assuming the optical drive is SATA, though. An XP desktop might well have an EIDE optical drive. -- J. P. Gilliver.

Like I said I guess I overreacted,...
As far as HD's I'll stick with the 2TB Seagates. I like them because they are quiet and dependable. I still use the WD as my external backup for the 8500. Thanks, Robert |
