Upgrading to an SSD
Using Diskeeper 12
Diskeeper is another popular defrag utility that has a proprietary algorithm to
optimize the location of files on your disk. Home and professional versions are
available, with the professional version offering an improved file optimization
feature called I-FAAST and a feature called Frag Shield that helps protect critical
system files from becoming fragmented.
There is no separate mode for optimizing boot files; just download a free trial
defragmentation starts immediately. Follow these steps to see Diskeeper at work:
1. Open the Start screen, type diskeeper , and hit Enter.
2. Scroll down and click Available Resources Used By Diskeeper.
Available Resources Used By Diskeeper expands to display a graph

Upgrading to an SSD
Solid state disks have a huge impact on the performance of your system. Priced
at around $110 for a 120 GB drive, they are becoming more affordable but are
still more expensive than a traditional one. However, the performance of solid
state disks is amazing.
I set up a simple test to show how fast a solid state disk is compared to the
average high-capacity traditional spindle hard drive. For this test I used a popular
disk benchmark utility called Crystal Disk Mark 3. If you want to play along
the performance utility with 1000 MB test sizes that were repeated five times
to create an average for each test criteria.
■ Sequential read and write —Reads and writes data to the disk sequentially,
meaning sectors or cells right next to each other, in 1024 KB blocks. For
example, the first part of the file goes in sector 1, the second part goes in
sector 2, the third part goes in sector 3, and so on.
■ 512 K random read and write —Blocks of 512 K in size are written and
read from all over the drive in a random order. For example, the first part
of the file is written to sector 423, the second part of the file is written to
882, the third part of the file is written to sector 102, and so on.
■ 4 K random read and write —Same as the 512 K test but with a smaller
block size of 4 K. The smaller the reads and writes, the slower the
operation is because the drive must do much more work to write a 1 GB file in
4 K blocks instead of something much larger.
