Ugh, this useless old red herring. The article shows that if your disk is under continuous writes of megabytes a second without pause that it will still last for YEARS. Some server deployments may be of this nature. NO desktop deployments are. If you like I could monitor iostat data for my workstation that acts a s a fileserver, does bittorrent periodically, on which I compile software, and develop software and so on. I can assure you that the disks are idle over 80% of the time.

When tracker hangs and keeps rereading the same file over and over, 100 % of the io is reading. SSDs can handle it just fine.

And, like any computer person, have had more then one harddrive fail prematurely. And, more importantly for the direction that PCs are going.. when you drop your laptop on it's corner you won't crash the read heads on a solid state disk. AND, SSDs for most purposes are much much faster. Low seek times, you see.

Ext4 hacker Ted Ts'o converts his laptop Posted Jul 3, 2008 22:39 UTC (Thu) by jwb (guest, #15467) [Link] The flash SSD market is very segmented. A lot of the disk-form-factor stuff out there has mediocre performance. However there is a company with a product on the market that's about 100-200x faster than disk on both reads and writes, both random and sequential, and especially on mixed read/write loads. The pricing is about $25/GB which isn't all that bad when you break it down.
