[hard drive] When to upgrade or add 2nd hard drive?

Is there a rule of thumb or recommended practice on when a drive is "full" enough to warrant adding a 2nd drive or getting a larger drive? My drive is 80% full which leaves me 22GB of free space. That's borderline for upgrading to Windows 8 I believe.

Not really - mostly personal preference.You should probably consider it when you don't have enough space to defrag (provided drive is not SSD) or you can't store/install what you want/need.

In Windows 8, that question might get a little harder. I say this because under Windows 8 you can add a HDD to a system and make it look like one large HDD.

Presumably this will work with SSD units as well. So if someone has a nearly full small 60GB SSD, they could add another larger SSD (say 240GB) when prices drop. It could then look like a single 300GB SSD.

No more installing or re-imaging the OS needed and one would think TRIM would work as well.

Well SSDs gc and trim work best when they're 50% or less filled.

So I'm not sure I'd do the spanned volumes as it would likely fill the 1st drive completely before filling the 2nd thus hindering trim and gc.

I'm talking theoretically at this point. I have a few Windows 8 licenses but have only installed it on an ASUS Eee Slate EP121 Core i5 tablet PC with single mSATA 64GB SSD.

So I haven't looked into it myself personally. I always suspected that the WHS version of Drive Extender would do some sort of load balance but again never looked into it. My guess is that if not supported already there will be tools to address this in the future. There really should be more granular control of such things.

Having said that I suspect the performance would be more then acceptable in many cases (at least in the short term).

Bottom line is this though. I may go through the effort of setting up things on my system(s) a specific way (ie the best way for performance) but that doesn't mean I would do so or suggest so for all others in all cases.

What I mean by that is if friends and family are asking for help with this i would inform them of the options but I wouldn't necessarily have the time to address it in any other way then the quick and dirty solution I suggested earlier. It could then be revisited later when there is more time. either way I am greatful for the option. I'm not going to charge them for it either so no harm and no foul.

Ya its a nice option,though I fear it would work like spanning disks in windows server rather than like a raid1.

Of course it would. You're not getting redundancy unless you are losing space.

I would personally avoid such spanning because you're worsening any failure (files using parts of both drives are gone, even files entirely on the good drive are going to be a PITA to recover) while not providing much benefit other than a little convenience.

Ah yes. Indeed if you are going to have 2 drives with 2 drives worth of space spanned just raid0 and back that shit up.

Spanning gives you a chance to recover some of the data after a single disk failure but it doesn't improve performance. You need a backup anyways might as well raid0.

The point would be raid0 would evenly write to the 2 disks, rather than fill one then start filling the next.

They could do it in a form of file level raid0 (ie alternate which drive gets the next file) in this way it would balance it and could have some metrics for differing sizes, also it would allow for some data to be recovered.

People should be running some kind of backup system (on and off sight) no matter what. I tell friends and family this all the time and naturally practice this myself.

RAID is great but it has restrictions that many of the average users don't want to be bothered with.

Also in the example I gave earlier who would really want to setup,a RAID 0 array using a 60GB SSD and a 240GB SSD? I could see a 256GB SSD and a 240GB SSD or a 512GB SSD and a 480GB SSD but not a pair (or group) that would result in significant loss of expensive storage.

True it's not good if the drives are significantly mismatched. In that case is it really worth mucking around for another 60GB, and probably a slower 60GB at that? Just use the 240GB and use the 60GB for something else, either a 2nd drive, an external, or to spruce up an old laptop.

Windows has decent tools built in for copying the image to a new drive, they're probably even better in Windows 8.

Right but I'm talking about doing a "Friday" job when friends and family need or want a quick solution. Maybe someone wants help over the phone but just isn't getting all the concepts involved.

Whatever the case, you're short on time and or willingness to help.

You pop in the new drive. Click a few buttons and you're done. If every second counts you go with what is fastest,...

Not necessarily the best option but its good to have options other then" I'll see what I can do next week,......if I have time,....and if I remember,.......".
