Atomos Ninja V – User Manual Edition 1: Aug 2021 4

Media

We have worked closely with drive manufacturers to develop media

designedspecicallyfortheAtomosNinjaV.TheAtomXSSDminiis

smaller than a standard SSD, but utilizes the same SATA connection as

normal HDD/SSD media and is compatible with all Atomos recorders and

dockingstations.AtomXSSDminitsdirectlyintotheNinjaVwithoutthe

need for a Master Caddy II.

Widely available 2.5” SSDs are the basic storage media for Atomos 4K

Monitor Recorders. We work closely with leading drive manufacturers to

qualify as many options as possible. SSDs are required for 4K recording or

for more demanding production environments that may not be suited

to spinning hard disks.

Which drives should you use?

There are so many drives available, and newer models appear all the

time. To avoid potential data loss and/or write/read errors, Atomos only

recommends the use of approved SSD media only.

We are not able to test all drives but here are some guidelines.

Solid State Drives (SSDs) are recommended for all recording up to

4KUHDp30andspecicdriveswithsustainedhighperformancewrite

speeds for 4KDCI 60p and RAW.

Spinning Disk Drives (HDD) are not recommended.

HDDs are not suitable for 4K recording or for use in environments or

situations where they are subject to movement.

Speed and reliability are the main factors. Here are a few things to

bear in mind:

• Disk drive data rates tend to be given in megabytes per second,

and codec data rates are normally given in megabits per second.

It’s very easy to get confused. But there’s no need to be, because all

you have to do to convert megabits to megabytes is divide by 8. So if

you’re recording at 220 megabits per second, that’s going to result in

220/8 megabytes per second, which is 27.5 megabytes per second.

• With 4K recording your data rate is approximately four times that of

HD recording, so please ensure your drive is capable of keeping up

with 4K write speed requirements.

Mechanical shock and vibration for Spinning Disk HDDs

Hard disks are precision mechanical devices that need to be handled

carefully. The use of mechanical drives or Solid State drives will vary

dependingontheintendedlmingapplication.

We can’t give rigid guidelines because there are so many different kinds

of drives, each which has different mechanical properties. You may even

ndvariationsbetweendrivesofthesametype.

What we have found is that mechanical drives are suitable for most

purposes that don’t involve harsh vibration or mechanical shocks. We

would not advise using mechanical disks if there is a likelihood that they

might be shaken or dropped onto a hard surface.

Here are some things that you should bear in mind when using

spinning disks:

• Even though spinning drives can withstand substantial shocks when

they are not in use, they are more vulnerable when running. Harsh

treatment that may not actually damage the drive may interrupt

recordings at a much lower level of severity. We recommend that you

experiment with your drives by testing them in the conditions that you

normally work in.

• Do not bang or jolt the Ninja V while recording.

• Do not use spinning drives (HDD) for recording 4K video

• Youwillndnoticeabledifferencesintheabilityofdifferentdrives

to withstand shock and to continue recording during vibration and

movement.

Secure Erase

For drives that carry the Atomos Logo such as the G-Technology 4K SSD,

Angelbird 4KRAW, AtomX SSDmini by Angelbird and Sony, an option

for Secure Erase is presented. This allows for the entire drive including

the drive cache to be formatted. This will erase ALL content on the drive

meaning nothing can be recovered. It will wipe all data off the drive

(which may also be useful as a additional security measure) and reset it

backascloseaspossibletofactoryconditions.Thebenetofthisfeature

is that it helps to maintain maximum drive performance, and therefore

should be used when available.
