(5400rpm) vs (7200rpm) hard drives for capturing?

[SRipper7]

I recently bought a 40GB hard drive but I didnt know anything about hard drive speeds, I just wanted one with 40GB, But after coming here and and other places reading about what system I should have to get good capturing and without frames droped, it was said that a 7200rpm hard drive was needed. So I looked up the model number for my hard drive and searched the net and realized that I had bought a 5400rpm hard drive instead (witch I regret!).
Should I worry alot about dropped frames...etc if I have a 5400rpm hard drive? is that 15% difference very big?

not necessarily, many new 5400 drives may be faster than last years 7200's because of increased areal density. the short of it is they put more in less space and so can read faster even at slower rotational speeds.

I got the 40GB Maxtor

Is that good enough for capturing at 704x480 8MB/sec or 6MB/sec with no frames droped?

For DV capturing, 5400 rpm is enough. Consider: you've got a drive capable of writing at 20 Mbyte per second, while the DV stream is only 3.6 MB/s. I have a 5400 rpm HDD myself and satisfied with it. It is Windows that sometimes mess things up, doing its deeds without prompting. I can always hear disk activity when Windows interferes. I mean, it could be an hour of digital output in progress and then some swaping process starts and ruines the run. But, yes, 5400 is enough.

8 MB/s? It is not DV then. But, anyway, 8 is less then 20.

Check out http://www.accessmicro.com. They have some pretty good prices on Maxtor OEM D740X drives. These are ATA/133 7200RPM. I just ordered two of the 60gb for $245 shipped.

I have a Seagate 20GB ATA66-5400rpm and I can capture 704x576 using huffyuv with negligible frame drops (~1 per 10 min). I use P4-1.5Ghz now. Previously my P3-500 could only capture 352x288 huffyuv.

Regarding your concern for dropping frames: My advice is, if you can afford it, buy an addition larger drive. This will keep the o/s from interfering with capture. One step further is to buy 2 drives and set them up in RAID 0 (Striping). Some Maxtors have something called Acoustic Management. This can cause problems with capturing too.
You can disable this and speed up the drive. BE CAREFUL before making any changes. Make sure you read the direction
Here is a link to their site for more info:

I didn't even bother reading this thread, but replied only to add my 2 cents.

You will want a 7200rpm or better drive for capturing, period. For IDE's, one of the best is the IBM 60GXP.
