Why SCSI?
Upgrading to SCSI
or choosing to go with SCSI right off the bat is not something you
should do without a decent level of study and research. First of all,
what are your NEEDS? If you are running an enterprise level or "high
end" file, mail or web server, then SCSI is a must. There just is no
reason to even try to
argue that point. As you drop lower on the food chain to a mid size
business with a network, SCSI based servers should always be your first
choice. When you drop down to a small business with a small network,
your budget is going to drive this decision. However, you must also
consider how much stress will be on the server. If the server is not in
high demand or isn't being accessed 24/7, then SCSI may not fit the
bill. Again, you must understand your NEEDS and what will best serve you
in a reliable and cost effective manner. Now when we look at
workstations, it really depends on what type of programs you will be
running. If your business is into graphic design or will be using some
other type of data intensive program, SCSI is the best way to go. If
your employees just use your workstations to type memos, check email and
surf the net, then SCSI is probably not the best way to go. Again, you
must understand your needs and build a reliable server or workstation
that best fits those needs.
What does the Cheetah
15K.3 have to offer?
The Cheetah
15K.3 is the lowest cost of ownership 15K rpm drive, and the lowest
cost-per-I/O disc drive ever. It is fast, cool, and quiet, and has the
highest reliability rating in the industry.
- 3D Defense System - The most
comprehensive drive protection system in the industry, consisting of
Drive Defense, Data Defense and Diagnostic Defense.
- SeaShell - Seagate's revolutionary
packaging protects the drive from external shock.
- SAMS - Seagate's Advanced Multidrive
System optimizes the drive for maximum I/O performance in Multidrive
environments.
- JIT - Just-In-Time minimizes actuator
impact on power, vibration and acoustics.
- Ultra320 SCSI - Up to 320-Mbyte/sec
transfer rate; Includes Packetization and QAS. Backward compatible
with Ultra160. Cables 15 devices, up to 12 meters.
- 15K RPM spindle speed - Delivers more
I/O's per second than 10K, and faster sustained transfer rates,
enabling the same high performance to be met with fewer drives.
I know what some of you are
thinking, SCSI technology is expensive. Well, you are right, it is
expensive. However, you mustn't think about the actual startup costs of
going SCSI. In order to appreciate what SCSI can do for you, you must
think about LONG TERM COSTS. For instance, most IDE hard drives only
have a backed service life of about 1 year under normal use. You are
lucky to get two or three years out of an IDE drive without the drive
degrading. With the Cheetah 15K.3, you are guaranteed a 5 year service
life and a MTBF of 1.2 million hours. Also, you must remember "normal
use" with an IDE drive is a game now and then, surfing the net and
downloading and installing files occasionally. "Normal Use" with a SCSI
drive is considered to be constant data transfer 24/7, 365 days a year.
This level of use would be considered "abuse" with most IDE hard drives.
