Yes, Goldyn Chyld you can use it with SSD too...I use it that way here.
Just have to tell that lastyl Smart Utility saved me a lot of problem with my datas, when my 3 To Hitachi looks to have problem with the Smart Status...I could just make a clone of it and 1 day later the HD was gone...ouch.
I changed for a WD Green as the Hitachi was no more buyable at a correct price ;-(
So, a big thanks to Smart Util and his developer.

Some have suggested that this program might be cheaper. And perhaps they are right.

However, after playing with the demo on a number of client machines and having it find issues that other utilities missed, I bought it. In fact I contacted the vendor about a special consulting license so that I could use it in my business.

I do like a number of other utilities out there. SMARTReporter, for example, is an outstanding free utility. However, I found SMART Utility to uniquely solve enough frustrating problems that I found it worth my hard earned $$$.

While SU offers some handy and useful info and renders it quite well, $25 IS too high,IMO; $10-$12, OK,OK,maybe as much as $15 would be an appropriate price point.
I just won't buy it for $25.

Is this a free update for the existing users?

SMARTUtility provides a wide range of information, but you need to be a real geek to make good use of it. I'd say it's for techies only. The biggest issue I have with it is that you can set some of the parameters for drive failure notice, but what the correct settings might be is rather arbitrary. For instance, the number of bad blocks that constitute a problem. Even new drives usually have a few bad blocks (out of millions of blocks), and a reformatting a drive will quarantine bad blocks so they won't be used thereafter. So how many bad blocks are a sign of trouble? The only way to really know is to scan the drive at some point and then (re)format it. If the bad block count begins to rise significantly from that point, as revealed on subsequent scans, then you would have cause for concern. But unless you set a benchmark, you have know way of knowing if things are getting worse or not. As I said, for techies only.

TechTool Pro 5 has an improved SMART test that benchmarks various categories of drive performance. But I had a drive fail recently despite passing this test with flying colors. So, though I wouldn't say SMART testing is useless, it's not foolproof, nor is it the only way to tell a drive has problems. In my case, a three year old Seagate drive in my Mac Pro gave out suddenly. No software repair utility would help; it was obviously a hardware failure. As it turned out, there was a sign of this impending failure that I did not recognize. Since it's uncommon, I'll mention it here. For some time my computer had been taking a long time to start up, spending quite a while with a white screen before the Apple logo showed up. I know now this was because the computer was having trouble mounting that failing drive - because when I replaced it, the startup slowdown went away. By the way, I had most of the data on the drive backed up so I didn't loose more than the time I spent troubleshooting the drive - and restoring the data to the replacement drive I installed.

I would say, therefore, that the real smart utility is a regular backup. In any case, SMART tests don't work on external drives so their usefulness is limited in any case.

All this doesn't mean, in my opinion, that SMARTUtility is a waste of money; it only means you need to know what you're doing to use it effectively.

Anyone who uses this app should be aware that it tries to hide a timestamp in a preference file named "com.apple.services.plist", which is apparently supposed to look like a file created by the OS. It isn't.
