Multiple SATA drive enclosure - can I do this?

I'm a bit concerned that they only have one fan and no temperature warning system. You could fix the last by using the drive SMART temps yourself. One advantage of the low density iCages is that if the fan fails (and good 120mm fans usually don't), your drives will probably be okay until you notice the problem. True. And since there is a lot of space between the drives, you should be able to put a fan speed controller on the fans and so get a nice quiet system even tho it has fans. Even if a high density rack has a warning system, you need have some sort of plan for a cooling failure (auto-shutdown, etc.) or your drives will cook. Sure, but that isnt that hard to do using the drive SMART temps. |

I remember looking at those myself. I'm a bit concerned that they only have one fan and no temperature warning system. Yeah, that's quite likely what they mean by "Power control, sensor & alarm". Makes sense. One advantage of the low density iCages is that if the fan fails (and good 120mm fans usually don't), your drives will probably be okay until you notice the problem. Even if a high density rack has a warning system, you need have some sort of plan for a cooling failure (auto-shutdown, etc.) or your drives will cook. Yeah, obviously it has no "Power control, sensor & alarm" . BR Dave Btw, babblehead, wasn't I in your killfile? |

Multiple SATA drive enclosure - can I do this?
I have had an Addonics SATA hot swap 4 drive bay (uses 3 5.25" slots) for over 2 years, with a Netcell raid level 3 (protected) card (can't find Netcell any more). NOTE: I had to 'flatten' drive guides in the pc case's 5.25" bays so the drive bay housing would slide in. 1.) you can get an Addonics 5 drive bay ($130) from them, I assume it also does a stagger start of the hard drives when you turn your pc on. There is a cooling fan on the back of the drive bay housing and it does keep all the drives cool. 2.) you want hot swap because a drive will drop out every 5-6 months (I'm running SATA Seagate 250 GB w/8mb buffer drives). I initially had 5 Western Digital SATA 100 & 120 GB drives in a raid level 3 (like a raid level 5) config. with the same problem. 3.) rebuilding a 250 GB drive will take +8 hours (if you have 465 GB of files), you can access the files before or during recovery (this is a 3 drive @ 250 GB each config). Having fewer files/GBs makes the rebuild faster. My 465 GB of raid protected storage is rebuilt or resized fastest by moving all files to a 500 GB drive and then performing the rebuild or resizing. 4.) I have seen an 11 " each, case (midi size) for $85.00 at Neo Computers. so they are out there. 5.) Western Digital has a stand-alone 1 TB network device (My Book) which has 2 500 GB drives in series (they can be mirrored, for 500 GB of protected storage). This device connects to a network port or a pc's ethernet connection. You can access it in your home network or thru the internet, if you want. Cost is $330 at Best Buy (when on sale). Just my experience at home (don't forget, use a power line regulator for your pc's protection). Pc electronics are very sensitive to voltage spikes and sags. -- rhd1953 ------------------------------------------------------------------------ rhd1953's Profile: http://www.futurehardware.in/members/3966.htm View this thread: http://www.futurehardware.in/558980.htm http://www.futurehardware.in |
