Seagate DB35 "CE" drives reviewed

Seagate have recently announced the availability of a new range of Consumer Electronics ("CE") drives for use in PVR and DVR applications. These are supposed to be quieter, cooler and generally better for PVR applications than standard drives, so I though I'd better check them out!
So, I've had 2x 250gb DB35 (Seagate "CE") drives on test since yesterday and can report the following:-
They appear to be based on the 7200.8 series of drives rather than 7200.9. The bigger ones, I guess, may be based on the 7200.9 - and will have to be for the 500gb - but we'll have to wait and see on that.
Seeks sound "softer" than the Seagate 7200.8 and 7200.9 drives - more of a chuckle than a chatter, but still significantly louder than a Samsung HA250JC in "quiet" mode.
Heat output appears to be less than the 7200.8 drives - these still get pretty warm, bordering on hot after a few hours use, just not as hot as the standard drives. Still a lot warmer than a HA250JC though, which never seems to get more than lukewarm.
As these are still 7200rpm drives (why?) some vibration/hum is still present. This tends to vary from drive to drive anyway, but the 2 evaluation drives I have seem pretty close to the better end of what I've seen for 7200rpm drives. Still not a patch on the HA250JC though, as those babies are almost entirely vibration free - so much so that I sometimes feel the need to double-check they're actually plugged in when I'm testing them!
Power requirements: Unfortunately, the "standard" 7200.9 series drives seem to have a higher startup power requirement than the 7200.8s and I haven't been able to get a pair of 7200.9s of > 120gb each to power up in a TiVo, whereas 2x 7200.8s of any size are absolutely fine. These "CE" drives are touted to have a lower startup power requirement than the 7200.9s, and sure enough these 250gb drives also work fine as a pair, but this is what I'd expect anyway if they're based on the 7200.8 series.
I Can't say anything about reliability based on a 24 hour test - but if they're as good as the other Seagate drives then this is where they may score best. Interestingly, the 2 evaluation drives I was supplied with have no warranty (they're OEM-only), but the retail drives should all have Seagate's industry-leading 5 year warranty, which may sway some in their favour.
So, in conclusion, if you really crave a 5 year warranty and are somewhat sensitive to noise then these are probably a better bet than Seagate's standard 7200rpm drives for TiVo use. However, they come at a price (currently around 20% extra) and still can't touch the cheaper Samsung HA250JC for quietness and cool running.
As for whether I'll be stocking them.... that depends on what price I can get them for - but unless they are at least equivalent to the HA250JC I don't currently see much point.
