[squid-users] Hypothetically comparing SATA\SAS to NAS\SAN for squid.

While working here and there I have seen that ZFS is a very robust FS.
I will not compare it to any others because there is no need for that.

OK so zfs, ext3, ext4 and others are FS which sits on SPINNING disks or
flash drives.
The SATA and SAS interfaces are limited to a serial interface in the
limits (by a standard) to 3,6 Gbps.
So SATA is max 6Gbps while a NIC can have a bandwidth of 10Gbps.
Are there any real reasons to not use a 10Gbps line?

For example if I have 10 SAS or SATA disks SSD or Spinning under a
machine with 128GB of ram it is possible to allow some flow of data to
be used and be "faster" then only one and even SSD drive.

A dual 10Gbps machine can potentially be faster in lots of aspects then
a local disk.

I do not have the answer but a NAS might be sometimes the right choice
as a cache storage.

Indeed there are overheads for each and every TCP connection and indeed
there are many aspects that needs to be tested and verified but I still
do suspect that there are some assumptions that needs to be verified to
make sure that a SAN\NAS might worth a lot then it is assumed to be.
