About LinkBacksJust got 2 of these (3200gb 16mb) and for some reason they have a jumped to drop speed from 3 Gb/s to 1.5... and it's on by default. SATA1 versus SATA2 or wot?

If the jumper affects speed only, I suspect it makes neglible difference to the actual performance. It's probably just there in case of compatibility problems. There again, I'm not sure whether that jumper would affect NCQ or other such things.

I've got a 320gb seagate 7200.10 as well
they limit the speed becasue the average joe might connect the drive to his motherboard and complain that it doesn't work/ is unstable...
Though it's because his motherboard only supports sata1.5gbs whereas without the jumper it would work at 3gbs, which the motherboard will not allow. Would the computer still work but be unstable, if the motherboard only worked with sata1.5gbs?
Anyhow, sata2 (3gbs) will not make much of a difference compared to the same drive working at sata1.gbs because the drive cannot transfer fast enough to saturate the bus
Ah! Have been in my raid setup recently and noticed that the controller was set to 3GB/s but drives were only reporting 1.5GB/s (4x 320GB 7200.10).
Guess I need to remove some jumpers tonight

Oh well i'm definitely doing it for bragging rights then - i mean, it's twice as big a number so that's much better

anything should work fine:
sata150 drive with sata300 controller
sata300 drive with sata150 controller
its just a case of bugs and delays with some controllers i think, so they put the jumper option on just in case
Some of the older controllers (like the ones on my NF7Sv2) don't like SATA2 drives, hence the jumper to disable it
BingoSome of the older controllers (like the ones on my NF7Sv2) don't like SATA2 drives, hence the jumper to disable it
And dont get me started on SATA150 vs SATA300 speeds
The only improvement I have seen in SATA 2 is the burst speed has increased, but that lasts for a fraction of a second, and is limited by the size of the Cache on the Hard Disk
Ive seen nothing consistent
The cache cant possibly fill up the bandwidth of SATA150.
Infact, I might do some benchmarking on this soon. See what it shows
Remember though, Benchmarks are like Bikinis - the show everything except what you really want to see
