ZDNet.com reports: "The high rate of failure is surprising, since
millions of flash chips get wave-soldered on PCBs every day. Likely
problem: the flash translation layer chip isn’t fully compatible with
notoriously finicky disk drivers.
The lackluster performance
problem is well known to regular Storage Bits readers - search on Solid
State Disk if you aren’t. I’m still working on unraveling the issues in
detail, but the basic problem is that flash was never intended for
frequent small random writes."
It looks like the first generation
Solid State Disks (SSD) are having some problems. They're also not
delivering any real performance advantages over the traditional
mechanical hard drives that we use today.
One thing that is not
addressed in this article is that you can only write to a flash memory
so many times before it fails. Currently, its generally about 100,000
write cycles per cell on the device. Although most devices don't write
to the same cell over and over again, instead they spreads out the
writes over many different cells.
