It was a tought decision for me...
I have heard great reviews about the Fijitsu MAM drives but I question their long-term reliability.
I am not sure about the reliability and performace about the IBM drives but I do like the performance on their IDE drives.
I was very parcial to Quantum SCSI drives until they got bought out by Maxtor. But the Maxtor SCSI line is just Quantum drives with a Maxtor name.
So my vote went with the Seagate Cheetah 15Kv3 because they are practically the fastest drive on the planet, have a good track record, heard great reviews, heard little complaints, and almost no problems. I wouldnt mind haveing a few to upgrade my 5 disk RAID array.
