Have always found Maxtor drives reliable. Cheap - I always think that depends on useful life - small drives like 15Gb for £68 (dabs.com) may sound cheap but to me 60Gb at £213 or 80Gb at £272 is much cheaper - they will be useful much longer. How many people still use the many 2Gb drives bought just 2 years ago?

That was five years ago, and yes, I still use them. They're perfect for an installation of Linux on a 486 machine.

http://www.gb.buy.com/promo/Coupon.asp?sku=84879378

use the above URL - click on the actual coupon and then browse to storage..

The best price/performance combo IMHO is teh Seagate 20.4Gb should be around £77 - £30 = £47.. I have two of them and on a Promise ATA-66 controller I get 22MB R & W a second reported by Raptest.. Transfering a 150Mb file from drive to drive (On the same cable!) gave 5MB a second..

The coupon is ONLY valid for new buy.com customers & is perfectly legitimate.. Buy.com want to increase there customer base - so take advantage of their generosity - its valid for ANYTHING from buy.com..

Be aware that an order i placed on 10th september for software in stock on date of order has yet to arrive.

They seem not to check no of orders against their stock when they confirm your order.

I have already placed an order so lets hope your experience is a one off but thanks for the advice.

They do have a freephone helpline ??

I'd just like to add that based on the above posts, I ordered the Seagate on the site (with £30 off) at 4pm yesterday. I've just checked the UPS on-line order tracking that confirms that it's already been delivered - even if it's gone to my neighbour which is a bit odd because 'er indoors is indefinitely indoors.

Well I have no complaints about Buy.com I placed an order for a Seagate 30.6 drive on the 5/10 and it arrived to-day.
That will do me I'm away to play now !
Thanks njc-2 for the advice

Bill S, where did you see the 60gb and 80gb drives i went to dabs & buy and the bigest they have is 30gb ?

Nick,
Try a quicksearch for Maxtor or http://www.dabs.com/products/prod-info.asp?stockcode=733-413-1090 for the 80Gb
and http://www.dabs.com/products/prod-info.asp?stockcode=733-413-1080 for the 60Gb

Note the prices are already dropping!

Ok so now I'm even more confused. I have a 27gig at the moment it is a UDMA66 and it runs at 7200rpm. The maxtor runs at 5400 so even though it's UDMA100 does that mean it will be slower than the one I have? Also the ad says that it's UDMA 66/100 so would it run on my mother board as it only supports 66.
ps thanks for that i must have been blind:)

yes they do.
parcels finally arrived on Thursday 12th october @5.00pm for goods that were in stock on 14th September ..... even with the money i saved i would have been cheaper buying locally with no one month wait for delivery.

they even told me off for returning parcels without a rma .... i didn't return them , there courier misplaced them for a week and they were not willing to help because i couldn't prove i had never received / returned them

will have to think seriously before buying from them again

Nick,
This whole speed thing is confusing - maybe we need a detailed article in CV. Certainly the Raptest speeds on my 80Gb 5400 are higher than my 28 & 38 7200s - perhaps it is due to the greater data density.

Does it make any real difference - if the drive is fast enough to dual stream then is there any great advantage in going 20% faster? (see Sept Opening Screem)

You're right, the whole drive-speed thing is confusing.

Think of it this way - the speed at which data can be read or written to a disk depends on the number of bits that pass under the disk head per second. There are two way this can be increased:
1. Spin the disk faster
2. Pack the bits closer together

By putting ever more data onto a disk, the manufacturers are following method 2 anyway, so disk access speeds go up by default. Access speeds that once needed 7200 RPM are now achieved (and more) by higher density 5400 RPM drives.

Interface speed (UDMA 33/66/100) is even less important. So long as the interface is faster than the disk, you will get the maximum performance. If your drive does 20 MB/sec, it'll do that just as well at UDMA 33 as at 100. If you use a RAID controller it's a bit different, you need the interface speed to be at least twice the drive speed to achieve the optimum.

And your final question is very relevant. Fast enough is enough! For people building say Web servers, the faster the better. There is no such thing as a disk that returns the data for a Web page too fast. But for an application like Video the parameters are fixed. DV is 3.5 MB/sec - provided your disk is fast enough to read/write that comfortably, something faster won't make it work any better.

In my experience "comfortably" means a raw disk speed of around 5 times the video data rate, so 15-20 MB/sec should do. The picture changes a bit with hardware that does real-time rendering as it may need to read two DV files simultaneously, so requirements double. And if you want to get into processing uncompressed video that's another leap - although still entirely feasible nowadays.

Thanks for that, I understand now. So how can I tell how fast my current drive is going?

Several of the capture card packages include a utility that will test and report the disk speed.

Sometimes you can find it from the manufacturers spec. but you have to look hard. You need the figure for "sustained data transfer rate". They are very good at giving seek time, average access time, maximum data transfer rate (interface speed), etc, but these are all largely irrelevant for video work. Sustained rate is the one you need to know!

There's a freeware program downloadable from http://huizen.dds.nl/~checkhd/. This runs under DOS and will give a very interesting speed profile of your drive. It's no longer actively supported, but as far as I know still works OK. I don't know if it has limits on the size of drive it can test.

You should be able to get a result by one of these means.

Thanks Richard and bill I tryed both your links Richard but gozilla rejected both???
The dvrap test gave me a read of 22 and write of 16 does that sound about right ?
