I guess I'm a heretic, because I've always been a reader, and I don't miss anything about physical books.-wraith808 (August 05, 2011, 07:24 AM)
It's not so much the actual read/write is it is the fact that every drive in the array spins up for every read/write - so there's more wear and tear on the drive mechanics rather than the disk platter's surface.-40hz (August 05, 2011, 10:53 AM)
If you saved a file to a single drive, only it would spin up and be written to (along with the housekeeping of finding sufficient free clusters. On a three element RAID-5, three drives would be spun up to accomplish the same thing, plus need to write additional information (i.e. parity) above and beyond that contained in the actual file itself. That's three times the disk activity plus "parity tax" plus three times the heat generated over a single drive save operation.-40hz (August 05, 2011, 10:53 AM)
) $5?So when you add in the MTBF for each of the three drives, you have a higher probability of a drive failing all other factors being equal.-40hz (August 05, 2011, 10:53 AM)
And most arrays have more than three drives since that's the least cost effective RAID-5 configuration since you always sacrifice one drive to parity even if that drive doesn't exclusively hold the parity data.-40hz (August 05, 2011, 10:53 AM)
Most times, the drives chosen for arrays are built to a higher quality standard than those normally deployed in PCs - so that may even up the failure occurrence rate up between server and non-server drives despite a higher utilization rate.-40hz (August 05, 2011, 10:53 AM)
if you are looking at things that could be added -- i'd love to see a full year calendar.-mouser (August 05, 2011, 10:49 AM)
Why would you be running T-Clock elevated??-Stoic Joker (August 05, 2011, 06:58 AM)
i ran TClock in the elevated state to see if that solved the problem of the calendar not appearing but it didn't. then i tried after disabling UAC, upon which the calendar appeared. i still don't know what to make of it. any suggestions?-lanux128 (August 05, 2011, 07:15 AM)
^ Um...actually the data chunks and parity info are distributed among all the drives in a RAID-5 array by the controller. There isn't a unique "parity drive" per se AFAIK.-40hz (August 05, 2011, 07:30 AM)
Raid-5 (and other "big storage" schemes) would be silly on SSD until their storage capability goes massively up. The added writes of raid-5 is a real concern,-f0dder (August 04, 2011, 05:07 PM)
Thanks for the program however after looking I cannot figure out how to display the calendar.-darkhelmet (August 03, 2011, 03:53 PM)
i'm having the same problem as darkhelmet. double-clicking does nothing even though i run it on an 'elevated' status. however if i disable UAC, then the calendar appears.-lanux128 (August 05, 2011, 05:55 AM)
Why would you be running T-Clock elevated?? Just keep an eye on the logfile size and do some periodic housekeeping. Because you'll be amazed how quickly some of those logs can grow depending on the level of activity and degree of detail they're collecting.-40hz (August 04, 2011, 01:34 PM)
Are you Zaphod Bebelbrox?Humm, didn't he have multiple heads rather than arms?-Stoic Joker (August 03, 2011, 06:55 AM)-f0dder (August 04, 2011, 02:03 PM)
Well ya ain't gotta smack me with a fish 
I'll drink to that! 
I haven't found that the security software I currently use "only serve to slow the machine down (typically to a crawl)." Not at all. My computer is delightfully fast and responsive. And WinPatrol Plus is not on my machine "just to monitor System files." I use it primarily for a variety of other functions; it happens to also offer the option of protecting the Internet HOSTS and key System files. Again, I haven't noticed that selecting this option negatively affects the performance of my computer.-cyberdiva (August 03, 2011, 07:40 AM)
The short and implementable-in-real-life answer: cover your eyes, and run away screaming, arms flailing.-f0dder (August 01, 2011, 09:55 AM)
...How do you flail and cover your eyes at the same time?Microsoft has a good introductory article that gives you what options are available for various levels of "collaborative" use of an Excel workbook. Link here. This is where I point my clients initially when the question comes up. Most are interested in the section that's headed: Allowing multiple users to edit a workbook simultaneously. Scroll down about midway to find it.-40hz (August 02, 2011, 02:05 PM)
This may be a very silly question, but it has to be asked:
if I dont use a password (admin account) is it all a waste of time anyways?-tomos (August 03, 2011, 02:15 AM)
Microsoft explains that because the UAC dialog box isn't on the secure desktop with the setting I suggested, "other programs might be able to interfere with the dialog's visual appearance.-cyberdiva (August 02, 2011, 04:45 PM)
This is a small security risk if you already have a malicious program running on your computer." The risk is obviously more than with a higher setting, but I don't think I'd say that UAC is rendered "pretty much useless" with the lower setting.-cyberdiva (August 02, 2011, 04:45 PM)
I mainly use my phone to make phone calls ... because, it's a phone.-Stoic Joker (August 02, 2011, 02:47 PM)
Yeah... I'm just not that popular.-Renegade (August 02, 2011, 02:51 PM)
Me either. The only reason that I have a cell phone is for emergencies. Most people just aren't important enough to need 24/7 connectivity that a cell phone brings. It's more for convenience than a need, truthfully.-wraith808 (August 02, 2011, 03:09 PM)
The folks that got us to where we are today all graduated with the highest of academic honors - and rather less obviously - Apparently not an ounce of common sense among'em-Stoic Joker (August 02, 2011, 12:00 PM)
Sorry to drift the thread, but that statement makes an implicit assumption that those folks have the same goals as 'the rest of us'. The guy who makes a huge mess for everyone else, but ends up with millions (or billions) in his bank account, might not care so much about the mess.-mwb1100 (August 02, 2011, 01:13 PM)
And don't be fooled by the "live rebuild" argument that says you can hot-swap and rebuild without taking your array offline. Yes, it can be done. But it's slow, and frustrating, and it drags server performance down so much that it's not practical for general purposes.-40hz (August 02, 2011, 01:48 PM)
Over time, I've begun to see the space limitations on physical drives as a blessing in disguise. The bigger the drive, the more disorganized they seem to become. And thanks to disk index/search utilities like Everything, most people can get away with it. Fling your stuff in folders - and put folders within folders out the kazoo - and screw organization! Just use a utility to root out where you put something when you need it.
(see attachment in previous post)
It works. But it's sloppy. And it's not a generally good way to handle file organization.
FWIW, I tend to assign specific drives specific types of data. That allows me to more easily setup backup and sync routines on a case by case basis. Critical files and directories may get mirrored in real time. Other directories may require version control. Others may get simple backups. Some don't get copied or backed up at all since they're kept for convenience and easily replaced with newer versions should they ever be lost. (Linux distro ISOs or Microsoft's WSUS files are a good example of that.)
Simpler is better when it comes to drive and directory setups. Especially on servers. And extra especially when you're as simpleminded as I am about these things.-40hz (August 02, 2011, 01:48 PM)
