I own two of these in a raid 0 array and IMO they are very nice drives. They are very cool, and when accessing data they are a lot quieter than my old seagates

I have one of these, and plan on a second very soon. It replaced a Maxton Diamondmax 10 that was doing the disappearing drive trick on me and my nForce4 ultra-D.


The Maxtor was no good, even if I could fix it, it was unreliable, many others had similar problems with it, even with the firmware update. Too bad, because there is a lot of options model and price wise for Maxtor.


I decided on the WD SE16 because it was common and new enough that I could get a second, third and fourth drives months down the road. It was also on the discount list from my supplier, and will be regularly. Only a couple bucks more than the Maxtor.


The only thing I've noticed so far, is the temperature sensor seems to be a little out of whack. No matter what I use to read it, it comes up with about 43-45 C. Touching it reveals a normal warmth. I have a 30 gig PATA maxtor right next to it, and I can't tell the difference between the two with my hand. Everest and MBM reads the maxtor as 23C, but I've seen it as high as 27.


Haven't had time to check and see if there is any sort of update to fix this, and it's been low on the priority list since it doesn't feel hot at all.


Both drives are in the lower chamber of an Antec P180, and I leave that fan on high because it's so big (thick) it doesn't make any noise. Case temp incidentally, is 25 C.


I'm inclined to think the maxtor is the one thats out, in fact most drives read about that temp, which would not be warm to the touch. Where temps in the low 40s would be warm.


Anyway, here's a screenshot of Sandra's benchmark, not too bad I think, since it isn't raid yet. But I'm still new to SATA and raid, so really have no basis or experience to compare it to other that what Sandra gives:


Sandra's Benchmark pic way too big to post and too lazy to edit!


And another shot of the Everest temps:




Other than the temp readings, I've had no issues at all. I can't hear the drive at all in this P180 case, but I couldn't hear the Maxtor either.


As soon as I can replace the PATA Maxtor with a larger PATA drive big enough to backup this 250, I'll be adding a second WD 250 and build a RAID 0 striped array. So unfortunately, the only thing holding me back from getting a second 250 to match this first one, is a silly old legacy ATA drive and the fact that I am too lazy and busy to do a complete reinstall manually. I've got the money for one drive, but not two, and can't really use one without the other. Doh!

Sweet deal though I am no WD fan either the drive I got back from RMA wont do full speed. I did not even bother returning the others.

My WD 250gb about 6 months old when it died :mad:

A data specialist told me the heads crashed against the platters :rolleyes:
