Hi all, I decided on the new Caviar black WD5002AALX hard drive. It also has a 32mb cache. I'm getting a poor burst rate with it though...typically around 70MB/s. In comparison to my WD2500JS, its has almost double the transfer speed, but this burst speed has me concerned.
This WD2500JS gets around 130mb/s burst.
I also had a WD5000AAKS with a 16mb cache and it performed better and had a fast (120ish) burst rate.
I only have a SATA II interface so I tried both with the jumped on and off to throttle the SATA interface but it didn't change the burst rate.
CPU seems higher on hte 5002 but that is the OS drive...the 2500JS is just in there to test.
Any ideas? Should this be normal? Is it possible my older MB doesn't like the 32mb cache. I would maybe think its chipset drivers but the WD2500JS seems to be fine in the same computer.
I didn't see any new firmware on the WD site but I'm not sure where to look on there.
