Seagate Momentus XT Hybrid HDD w/ built-in 4GB SSD

[wwoods]

I don't have anything to compare it to, but I do not have any complaints. The drives just work.

If you have other benches against this drive, perhaps that would help:

Question for ya, have you noticed, in your raid1 configuration, it gets a tad bit warmer ?

[jclausius]

Nothing to measure against, but I don't believe the system runs any hotter than if there were two other platter based HDDs in the system. To me it seemed my old NP9860 ran a bit hotter w/ 3 HDDs in RAID-5.

Aneother question if I may, when ya have the raid1, in RST you have the option to "initialise" it. Now, in a raid5 I understand why you do that, to calculate the parity, but since a raid1 is a strict mirror, whats the reason for initialisation, I cant fathom the reason in a raid1.

I also see the Intel RST also offers a "Recovery" option, from what I can find on the net, its like a more flexible raid1 ? anyone have experiance with that ?

In any RAID setup, you need to synchronize the drives (that is why identical HDD models give the best results...). Initialization in RAID1 is what does this 'sync'.

Ahh, thankya thankya.....appreciate that info

[jclausius]

Dunno about the initialization. It might be something that the driver writes out to the drives to show they are both sync'ed and participating in the RAID volume. So, if the driver looks at those stamps and they are different, then the driver would know one drive is not the mirror of the other, and the RAID volume is degraded. Note, this is just a big wild a@@ guess.

In regards to "Recovery", from what I can tell, Recovery is what RST calls RAID-1. RAID-0 is called "Optimized."

It seems like last 10 pages are 80% about RAID. Nothing wrong with that it's just not that interesting for everyone. If anyone wants to discuss RAID for Momentus XT further please make a new thread.

Thats my fault......started off by talking about SD28, and then I brought up Raid1 / Raid0 with those things and it took a life of its own. Probably because I had such a smashing experiance with them in a raid5 many moons ago.....

anyway...subject dropped

Ok so i just found out my replacement alienware apparantly has this drive. I barely notice any difference from my old laptop's 7200rpm drive. Is there a way to optimize this hard drive for quick boot times?

[Phil]

Make sure you have firmware SD28. Reboot three times and measure with boottimer.exe.

The Xt boots about 20% faster than a 7200rpm drive.
