What other 10k RPM SATA HDDs are there out there? Ive only heard one name. Western Digital Raptor. Are there any other reliable 10k HDDs out there?

Competition against their own 10K SCSI lines?movax said:You'd think the other manufacturers would have provided some competition by now, but WD is continually kicking ass as usual. They have been ever since they started the JB Caviars IMO

Not likely
Err, seek latency is actuator latency plus rotational latency. No matter how fast your actuator, you still have to wait for the disk sector to move underneath the head.WD probably could get that 1ms just by putting a 15K grade actuator on the Raptor and reducing seek time, without taking the environmental hit of a 15K spindle.
The same benefits on seek times...but not bandwidth.Also, if you reduce seek time 1.2ms, you achieve the same benefit as going from 7200 to 10K.
If you run a raid 1 array on a good controller, it'll effectively do this (on reads, anyways...).masher said:The same benefits on seek times...but not bandwidth.
I wonder if drive makers have ever looked at adding a second actuator to each platter, mounted 180 degrees opposite. That would halve rotational latency as well as doubling transfer rate-- it should allow a 10K drive to perform like a 20K. Expensive...but at some point its got to be cheaper than upping spindle speeds still further.
Right...too bad it kills the write performance thoughunhappy_mage said:If you run a raid 1 array on a good controller, it'll effectively do this (on reads, anyways...).
