    I'm looking at the possibility of adding a 160-Gig hard disk to a machine that I intend to use for recording from cable TV directly to the hard disk. I already have the ADS (USB2) conversion box. I would like to stick with a Seagate Barracuda disk as that would more it likely that I could transfer the entire drive image to the new disk and still have Windows 98, Windows 2000, and Windows XP run without having to reload the operating systems.

    I have looked at the Barracuda disks at PriceWatch; but, I cannot find any 160-Gig drives there that have more than 2 Megs of cache. Now, in the past, I have not been able to detect a performance difference between 2-Meg and 8-Meg-cache drives; but, that has always been on drives 80 Gigs and down in size.

    Comments anyone?

    YES! YES! YES! (y)

    I bought a SATA 160 gig Seagate a few weeks ago, and it is screaming and works like a.... ...well, a Barracuda :D

    I think the 8 meg does help. CompUSA had 200 gig Seagates on sale for 99 bucks. Watch the Sunday paper for sales ;)

    I have seen the highest performance I've ever measured from a IDE drive from a 7200 RPM WD with the 8mb cache. It does both random and large file transfers about 20% faster than the same capacity drive (120gig) with a 2mb cache.

    I've been looking at Pricewatch and I don't see any 160's with 8 Megs. I do see some 200's. Maybe I'll go for 200.

    I'm gonna have to do some checking and see how many minutes of TV-type video I can store per Gig. Anyone want to venture an educated guess?

    By the way, I liked the old format better--where the original popster's name was more prominent and in a column by itself.

    Thanks.

    I have a 30-Gig here that will get me more than started, in that case.

    That'll be 30 hours in that case.
