Sir,
Thanks for your suggestion,
I will go for blob storage, because our application will maintain the data on
yearly basis[stupersonal2008, stupersonal2009 etc.]. So i feel we may not face
such kind of performance issue in our application.
Thank you
VIKRAM A

I never said you had to grovel, though :-p
This whole thread has been a discussion of just that. My personal opinion is
that it's better to store binary objects (like images) out-of-band, for
instance on an NFS system like you suggest. Other people on the list have made
their own arguments for BLOB storage.
In the end, it's down to your own situation and decisions, but I will keep
defending the position that filesystems are made for storing files, and
databases are made for storing data - it saves you on both database and PHP
requests, as (from a web point of view) you can't return the image data inside
your HTML - it requires a second HTTP call. Filesystem image serving, however,
could perfectly be offloaded to a subdomain that runs a lightweight, threaded
HTTP server that need not run the heavy PHP processes. You could even run that
on your NFS server, if you want.
If you do go for BLOBs, though, for god's sake keep them in a separate table,
lest you fragment your datafiles. Split records are a disaster for performance.
