Housing two 2.5-inch hard disks in one 3.5-inch drive bay?
Found such a toy in local computer shopping arcade.
Is it gonna kill both hard disks by heat? -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

I'm considering one of these, or perhaps 4x 2.5" in a 5.25" bay. Two 2.5 inch 500 GB disks will be around twice the price of a single 3.5" 1 TB disk, but as far as I can see they will be quieter and lower power (even with two of them), and faster (using raid0). |

My Samsung 3.5" 1.5TB drives are completely silent, you have to listen very carefuly to see if they have spun up in a USB docking station. MUCH better value and speed too. |

I like mine too, Samsung ecogreen 5400 1T. Value is median, quality and reviews for Samsung are higher up to 1.5T. Above, 2T, only Hitachi is going for the value -- 2T $134 rebated to a $110 1.5T Samsung. 2T for pushing $200 with the rest will have to wait for better values. May do another one after awhile, 1.5T WD's audiovisual HD might be a choice, (possibly then a Hitachi after WD), although with WD and XP that involves getting into WD's new 4K sector alignment. Win7 is already implemented. For XP, not too major, more difficult to actually understand, although WD does offer a couple easy ways of going at it with, either their software or a XP-compatibility jumperpin on the HD -- unless someone were regular type in server fare with command line utilities (*nix) for adjusting large-drive alignments. 4K sectors look to be the writing on the wall past 2T - though 4K may not be the standard sector size until 2013-14. |

My Samsung 3.5" 1.5TB drives are completely silent, you have to listen very carefuly to see if they have spun up in a USB docking station. I haven't paid much attention to disk drive noise or power requirements before, but I'm planning on having several drives on a new machine (to play around with raid) and so the total drive noise is (perhaps) going to be noticeable. It's useful to hear people's experiences with modern drives - "completely silent" is more helpful than "2.5 Bel" on a web page of drive specifications. MUCH better value and speed too. There's no argument about value. I had a look at some details of drives on Samsung's website, and was somewhat surprised by some of the specification details. I had thought that the seek time for 2.5" drives would be lower than for 3.5" drives since the maximum movement distance is smaller. Apparently that's not the case. And the disk-to-buffer transfer speed is almost twice as fast for the 3.5" disks. It also seems that there is little difference in the noise, although the the 3.5" disks take more than twice the power of the 2.5" disks. All in all, I think I'll be going for 3.5" disks. While 2.5" have the potential for being faster in that you can fit more into a given space and run them in parallel, it's just not going to be worth the money. |

I guess we need to wait for 2.5-inch drives to get mass production. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

I've had at least two notebook drives die of a heat death. One time it was in one of those slim-line USB cases, and another time it was inside a laptop itself. Yousuf Khan |
