Seagate 10K.7 vs. WD Raptor 740GD

[Kennyshin]

Seagate 10K.7 drives will begin to appear at retail shops but they are only SCSI. WD Raptor 740GD is known as the fastest IDE drive available so far but it is an SATA and costs over US$200 with which one can have two 200GB IDE drives and use them as a 400GB RAID 0 array.

If your motherboard has both S-ATA and SCSI 320 onboard, which willl you choose between 10K.7 and 740GD?

I haven't tried any Raptor. I've used only 7200 RPM SATA and PATA drives and some 10K RPM drives like Seagate's 10K.6. I'm not going to buy any 15K RPM drives because they usually cost 2x more than 10K SCSI.

If you paid the extra money for a motherboard with onboard Ultra320 SCSI, you should use it! (I'm in the same situation, I have a Gigabyte 8KNXP-Ultra64, so I definitely want to make good use of those SCSI ports)

While SATA is a excellent replacement for the falling IDE, SCSI still has a few more features that SATA doesn't (In fact, I think SCSI is getting its own version of SATA here pretty quick). Speed-wise the Raptor might be a smidgen faster, but if I had the choice I'd go with the Seagate SCSI for data reliability alone.

Correct. Only additional thing to consider with SCSI is heat and noise. They typically run hotter and louder.

FYi 74GB Raptor is less than $200... last time I saw, $180.

If I had to make such a choice, it would be the Seagate. As said before, SCSIs do run hotter and louder. So it's very important to verify that your case temp is under acceptable levels.

10K.7 has been tested? The comparison is between 10K.7 and Raptor.

I have two 10K.6 drives. I'm not sure whether Raptor 10K rpm drives generate less heat and noise than 10K.7.

Compare 10K.6 and 740GD.

Now look at the dates. 740GD was reviewed in Jan. 24, 2004 and 10K.6 was reviewed in Sept. 16, 2002. That's a 16-month difference. It is fair to compare 10K.7 and 740GD. It's not exactly like comparing SCSI HDD vs. IDE HDD in general.

I use P-ATA, S-ATA, SCSI, USB, IEEE 1394, all of them.

I mean if you compare the latest SCSI drives against the latest IDE drives, you might feel SCSI drives are not that hot and noisy. My 10K.6 drives seemed quite cool and silent compared to some IDE drives I used a few years ago.
