I spent more time working on SSDs that weren’t the X25-M than the Intel drive itself. The Intel drive just worked as it should, the rest of them didn’t.

Fascinating article on SSDs. Until now, I have been aware of SSDs but largely ignored them due to cost-per-gigabyte for this heavy-duty data user. They're starting to get interesting. I doubt my _next_ drive will be an SSD, but the one after that probably will be. Given these sequential read/write numbers, I do look forward to putting my Aperture library on an SSD.

Best article about SSD technology ever written.

) doesn’t know how to use raw flash. So if you want a few 80 gigabytes of flash in a laptop, today the only way to get it is with it attached to a SATA interface in a 2.5″ laptop disk form

[...] what could be done to tweak Mac OS X in order to, at least minimize the write amplification problem and also optimize the space used – yes you know the €/MB ratio is high on SSDs. Most of these tweaks, besides providing for a longer lifespan for SSD disks, should improve overall system performance even on an non SSD disk. Of course you will use them at your own risk…

Ok, I have an Intel X-25M 160 GB SSD coming and I’m on a VERY GEEKY mood… so I decided to poke around a little on what could be done to tweak Mac OS X in order to, at least minimize the write amplification problem and also optimize the space used – yes you know the €/MB ratio is high on SSDs. Most of these tweaks, besides providing for a longer lifespan for SSD disks, should improve overall system performance even on an non SSD disk.

<p>The 2.6.30 kernel is chock full of next-gen file systems. One such example is NILFS, a new log-structured file system that dramatically improves write performance. </p>

Solid-state drives (SSDs) have grown popular in recent years for the impressive speed increases your system gains using them. To get the most from your SSD, however, you can (and should) do a few things differently.

The write speed of Solid State Drives is usually lower than the read speed. Many write operations on SSDs can slow down the system performance and reduce the longevity of the drive. Specialized programs such as SSD Drive Tweaker or Flash Fire aid the user in optimizing the system for Solid State Drives.
