Re: SSD Analyzer Tool

I thought I would try my 1st post to this forum to test the waters. I can't speak to IBM's SSD reliability 1st hand since we do not have any. But, I will say that the SSD in my MacAIR is awesome and has been heavily used for about a year. Secondly, I see that FusionIO just announced a 10 terabyte SSD. With that kind of progress in this technology, can spinning disks really be around much longer? If not, it could be critical for server manufacturers to make the right decision now on how much of their development dollars to spend on HDDs vs SSDs?

Here's what I don't understand. Rob says he replaced a drive because it
reported FAILED. I didn't get the sense that there were any warnings,
it just fell over. Now, if the whole idea on these drives is that they
have a bunch of extra space that they use to replace failed blocks,
wouldn't it make sense that:

A. You would have a way to see the amount of "extra" space remaining on
a drive.

B. The drive would warn you as it was losing it's extra space. Say send
a message to the system operator when a drive uses 50% of it's spare
storage, then another at 75%, 90% and every 1% after that.

I'm not a hardware guy, but that would make sense, wouldn't it?

Joe,

I know there's been A LOT of people leaving the midrange ranks over the
years, but my more than ample gutt tells me that the problems of the 9335(?)
drives failure rates is still a stink that IBM works hard to avoid in any
"disk" technology it releases...
