Determining what
storage application works best for you can be a difficult task. Luckily, we
have an amazing support team and plenty of great resources to help you get the
right 45Drives storage solution for your specific needs.
If you are out of
storage or running out of storage but are not sure what you need – this guide will
help you decide which Storinator storage server and configuration is best for your data needs.
The Storinator storage
server’s configuration is flexible, this gives you an advantage an enables you
to get exactly the right system for your use case. However, it can be slightly intimidating
when you’re making the purchasing decisions. That’s why we designate a specific
account manager for you. They are there to help you every step of the way and to
make sure you’re getting the exact storage solution you require. If you’re

Storinator Buying
Guide
The first step in
choosing a Storinator storage server is asking these questions:
How
much storage space do I need?
This seems like an obvious
question, but it can be a little more difficult to determine. First, think about
your current storage capacity. At what
rate is your storage server filling now and how much is that rate increasing?
Think about the
timeframe you want to purchase storage for. With all this information you
should be able to determine what useable capacity
you’ll need over the lifetime of your NAS.
Please note: When we talk about raw capacity
we mean the capacity of the Network Attached Storage (NAS) plus the number of
drives, multiplied by the size of the drive. For example, if you have a
Storinator S45 populated with 10TB drives that gives you 450TB of raw storage.
It’s important to
remember that the useable capacity of the NAS is less than the raw capacity.
The useable capacity is affected by
things like RAID level and which operating system (OS) you use. Which leads to
another question you will want to ask yourself.
What RAID level do I need?
- RAID 0 – Has no effect on useable capacity and the highest performance of any RAID level. But if one drive is lost the entire RAID will fail.
- RAID 1 – 50% of raw capacity is lost to redundancy. You won’t lose any data unless you lose both drives from a mirrored pair.
- RAID 10 – 50% of raw capacity lost to redundancy. Faster than just a RAID 1 but if you lose two drives from the same mirror then the entire pool is lost instead of just the contents of one drive.
- RAID 5 or 50 – 1 drive worth of raw capacity is lost to redundancy per RAID 5 array. The pool will still be able to rebuild if you lose one drive but is very vulnerable during rebuild. RAID 5 is slower than RAID 0.
- RAID 6 or 60 – 2 drives worth of raw capacity is lost to redundancy per RAID 6. You can withstand two drive failures per array. Slower but considered by many to be a good trade-off with a RAID 10 for the increased space efficiency and strong redundancy.
The decision between
different RAID levels will be a choice between these attributes:
- Storage efficiency
- Performance
- Redundancy
- Rebuild times/safety
- Cost-effectiveness
For more information
on the tradeoffs between raid levels check out our blog, article, or video on the subject.
The equations for how
each of these levels affects space efficiency are:
RAID 0
|
RAID 1/10
|
RAID 5/50
|
RAID 6/60
|
(n)
|
(n/2)
|
(n-1 * drive size)
|
(n-2 * drive size)
|
Where (n = number of
drives * drive size)
Once you have
determined your required size is you can figure out which model of Storinator
you will require. We have a RAID calculator for both RAID and RAIDZ that is free to use.
If you just want to take a quick glance, in the table below are useable
capacities for each RAID level.

A certain amount of
open space is required for performance overhead from the OS, sometimes as much
as 20%. The numbers above show the actual useable capacity for your Storinator storage
server.
