My application is Adobe Premiere (and various other Adobe related products).
I'm using the 10k drives at the moment for my PD-170 footage instead of a
RAID but with the need for additional space for HDV content, that approach
becomes slightly more expensive. I'm considering making one of them my
system drive in a new build and going with a RAID, but I wasn't sure if I
could get enough speed out of one for HDV footage... I still haven't done
all my research yet.
Here are the specs on the 10k drive if anyone's interested:
Average latency 2.99 ms
Buffer 16 MB Cache
Read Adaptive
Write Yes
Data transfer rate (buffer to host)1.5 Gb/s (maximum)3
Drive ready time7.0 sec (average), 10.0 sec (maximum)
Error rate (non-recoverable)<1 in 1015 bits read
LBA support Yes
MTBF 1,200,000 hours
Rotational speed 10,000 RPM
Seek time
Read 4.6 ms (average)
Write 5.2 ms (average)
Track-to-track seek
Read 0.3 ms (average), 0.6 (maximum)
Write 0.4 ms (average), 0.75 (maximum)
Start/stop cycles 20,000 minimum
