Use the NAS as your own personal cloud. Here are some key features:
• Start using Zyxel NAS instantly with FindMe - Use Zyxel FindMe to discover your NAS on your home
network and get in control in under 15 seconds. Then do an easy installation with no need to install a
NAS utility.
• Access and share files from your NAS wherever you are - Using the Zyxel Drive mobile app makes it
easy.
• Create a shared cloud space for people without a NAS - Provide your cloud space for your friends or
family members when you share a folder from the NAS with the Zyxel Drive mobile app. Your friends
and family members don’t need to purchase an additional NAS - just install the Zyxel Drive mobile
app on their mobile devices.
• Protect your data from drive failure - The NAS’s RAID 1 capability clones contents from one drive to
another. If a drive is damaged or corrupted, you still have another drive to restore from or use.
• Get up and running quickly with the easy-to-use in terface - The Zyxel NSM (NAS Station Management)
5.2 intelligent desktop provides a rich feature set of tools with an easy-to-understand GUI design to
help you get things done quickly. The multitasking capability through a multi-window interface
enables you to quickly get applications up and running.
• Check your NAS while you’re away - Even if you have several Zyxel NAS devices, visit the
myZyxelcloud Web portal from anywhere to see their health status at a glance.

for details about managing the NAS’s configuration file). You could then restore your configuration in
the event that you or someone else reset the NAS to the factory defaults.
Note: Keep the NAS in a secure location in order to prevent unauthorized reset of the device.
If no IP address information is assigned, the NAS uses Auto-IP to assign itself an IP address and subnet
mask. For example, you could connect the NAS directly to your computer. If the computer is also set to
get an IP address automatically, the computer and the NAS will choose addresses for themselves and
be able to communicate.

Repair Volumes or Disk Groups
If a hard disk in a RAID 1 with a hot spare or a RAID 5 with a hot spare fails, the NAS automatically uses
the hot spare to re-build the volume or disk group. Later you can replace the failed hard disk and add
the new disk as a hot spare.
A hard disk failure in a RAID 1, RAID 5, RAID 6, or RAID 10 degrades the volume or disk group. Replace
the failed disk and use the Internal Storage screen’s Repair link to repair the volume.

Table 32 S.M.A.R.T Info
LABEL DESCRIPTION
ID This is the identification number used to tag a hard disk attribute.
This is standard across all S.M.A.R.T-enabled storage devices. However it depends on the
storage vendor which attributes it will allow S.M.A.R.T to diagnose.
Attribute This refers to an attribute of the hard disk that S.M.A.R.T can assess. Attributes describe the hard
disk’s physical state, performance, wear-and-tear, and so on.
Value This is a value that corresponds to the Raw Data. Compare this with the Threshold.
S.M.A.R.T compresses the raw value(s) into a digit from 1 to 253, where 1 indicates the worst
scenario while 253 indicates the best scenario.
The values 100 or 200 usually represent the mean or normal value.
Worst This is the lowest value attained by the hard disk since S.M.A.R.T started its assessment of the
hard disk.
Threshold This is the attribute’s threshold value. If the attribute’s current normalized value is less than or
equal to the threshold, the attribute has failed. An attribute value close to or below the
threshold indicates the hard drive is no longer reliable.
Type This shows S.M.A.R.T’s assessment of the hard disk.
Old_age indicates end-of-product life from old-age (normal wearing out) if the attribute value
is less than or equal to the threshold.
Pre-fail indicate imminent hard drive failure if the attribute value is less than or equal to the
threshold.
Note that just because an attribute is of the Pre-fail type does not mean your hard drive is
ready to fail. It only means this if the current normalized value of the attribute is less than or
equal to the threshold.

LABEL DESCRIPTION
Updated This indicates when the hard drive updates the value for this attribute.
• Always means the hard drive updates this attribute during normal operation and during
• Offline means the hard drive only updates this attribute when no one is accessing the hard
When Failed This column indicates when (if ever) the attribute failed. An attribute has failed if the normalized
value is less than or equal to the threshold.
• -: This displays if the attribute is not failing now and has never failed in the past.
• FAILING_NOW: This displays if the attribute’s current normalized value is less than or equal to
• In_the_past: This displays if the attribute’s current normalized value is greater than the
Raw Data This is the attribute’s unprocessed raw data. These values show exact amounts of time or
numbers of attempts or errors. The meaning to the raw values is specific to the hard drive
manufacturer. Table 42 on page 156 has some information about whether a higher or lower
individual raw S.M.A.R.T. attribute value is better.

Low This is how many times the heads are loaded off the media.
Low This is the number of load and unload cycles into head landing zone position.
High This is the time between ECC (Error Correction Code)-corrected errors.
Low This is the total number of reallocation (remap) operations. The raw value is
the total attempts to move data from reallocated sectors to a spare area.
Successful and unsuccessful attempts are both included.
Low This is the number of unstable sectors awaiting reallocation. If the sector is
later successfully written or read, this value decreases and reallocation is not
performed. Only failed write attempts cause a reallocation, not read errors.
This can be difficult to test since only direct I/O writes to the disk cause
reallocations, not cached writes.
Low This is the number of errors reading or writing a sector that were not
correctable. An increase in this value is an indicator of disk surface defects or
mechanical subsystem problems.
Low This is the number of data transfer errors through the interface cable
according to the ICRC (Interface Cyclic Redundancy Check).
Low This is the total number of errors in writing sectors.
Low This is the number of read/write head off-track errors. If the value is not zero,
make a backup.
Low This is the number of data address mark errors. This could also be a different,
manufacturer-specific attribute.
Low This is the number of errors corrected by software ECC (Error Correction

5.6 Technical Reference
This section contains background on JBOD and the RAID levels used on the NAS.
JBOD
• Minimum number of disks: 1
• Total capacity: Sum of the member disks
• Advantages: Maximum storage capacity, especially for disks of mixed sizes. Flexibility (you can add
disks to the JBOD
• Disadvantages: Not as fast or reliable as RAID.
JBOD allows you to combine multiple physical disk drives into a single virtual one, so they appear as a
single large disk. JBOD can be used to turn several different-sized drives into one big drive. For example,
JBOD could convert 100 GB, 200 GB, 250 GB, and 500 GB drives into one large logical drive of 1050 GB.
Since data isn’t striped across disks, if one disk fails, you should just lose the data on that disk (but you
may lose data in the whole array depending on the nature of the disk failure). You can add disks to the
JBOD array later (using the Add disk to JBOD feature) and even remove them so JBOD offers a lot of
flexibility. However JBOD read performance is not as good as RAID as only one disk can be read at a
time and they must be read sequentially.
Data is not written across disks but written sequentially to each disk until it’s full.
The following figure shows three disks in a single JBOD array.

DISK 1 DISK 2 DISK 3
RAID 0
RAID 0 spreads data across two or more disks (data striping) with no mirroring nor parity for data
redundancy, so if one disk fails the entire array will be lost. The major benefit of RAID 0 is performance.
The following figure shows two disks in a single RAID 0 array. Data can be written and read across disks
simultaneously for faster performance.

Chapter 5 Storage Manager
RAID 0 capacity is the size of the sum of the capacities of the disks in the RAID 0. For example, if you
have four disks of sizes 1 TB, 2 TB, 3 TB and 2 TB respectively in one RAID 0 array, then the maximum
capacity is 8 TB.
Typical applications for RAID 0 are non-critical data (or data that changes infrequently and is backed
up regularly) requiring high write speed such as audio, video, graphics, games and so on.
RAID 1
RAID 1 creates an exact copy (or mirror) of a set of data on another disk. This is useful when data
backup is more important than data capacity. The following figure shows two disks in a single RAID 1
array with mirrored data. Data is duplicated across two disks, so if one disk fails, there is still a copy of the
data.
Table 48 RAID 1
A1 A1
A2 A2
A3 A3
A4 A4
DISK 1 DISK 2
As RAID 1 uses mirroring and duplexing, a RAID 1 array needs an even number of disks (two or four for
the NAS).
RAID 1 capacity is limited to the size of the smallest disk in the RAID array. For example, if you have two
disks of sizes 150 GB and 200 GB respectively in one RAID 1 array, then the maximum capacity is 150 GB
and the remaining space (50 GB) is unused.
Typical applications for RAID 1 are those requiring high fault tolerance without need of large amounts of
storage capacity or top performance, for example, accounting and financial data, small database
systems, and enterprise servers.
RAID 6
RAID 6 can tolerate two simultaneous drive failures by calculating dual distributed parity data on striped
data across disks. Dual parity provides extra data protection, however, it is slower to write than most
other RAID levels.
RAID 6 uses parity to store redundant data on space equal to the size of two disks for later data
recovery. Therefore, on a RAID 6 array, only 50% of the space is available as usable capacity. If you
have four disks of sizes 1TB, 1TB, 2TB, 2TB respectively in one RAID 6 array, then the maximum capacity of
NAS Series User’s Guide

Page 93
Chapter 5 Storage Manager
the array is the capacity of the smallest drive (1TB, 1TB, 2TB, 2TB) * (Number of disks - 2) = 1TB * (4-2) = 2TB.
The remaining space (2 TB) is unused.

RAID 10
RAID 10 (RAID 1+0) is a nested RAID where two RAID 1 arrays are stored on the physical disks with a RAID
0 array on top. It is a stripe of mirrors. RAID 1 provides redundancy while RAID 0 boosts performance. The
following figure shows two disks in two RAID 1 arrays. Data is duplicated across two disks, so if one disk
fails, there is still a copy of the data. These two arrays are configured as a single RAID 0 array for faster
performance

DISK 1 DISK 2 DISK 3 DISK 4
Typical applications for RAID 10 are those requiring both high performance and reliability such as
enterprise servers and high-end moderate-sized database systems. RAID 10 is often used in place of
RAID 1 or RAID 5 by those requiring higher performance. It may be used instead of RAID 1 for
applications requiring more capacity.
RAID 5
RAID 5 provides the best balance of capacity and performance while providing data redundancy. It
provides redundancy by striping data across three disks and keeps the parity information (AP) on the
fourth disk (in each stripe). In case of disk failure, data can be recovered from the surviving disks using
the parity information. When you replace the failed disk, the reconstructed data is written onto the new
disk. Re-synchronize the array to have it return to its original state. The following example shows data

Chapter 5 Storage Manager
stripped across three disks (A1 to A3 in the first strip for example) with parity information (AP) on the
fourth disk.

A1 A2 A3 AP
B1 B2 BP B3
C1 CP C2 C3
DP D1 D2 D3
DISK 1 DISK 2 DISK 3 DISK 4
The capacity of a RAID 5 array is the smallest disk in the RAID set multiplied by one less than the number
of disks in the RAID set. For example, if you have four disks of sizes 150 GB, 150 GB, 200 GB and 250 GB
respectively in one RAID 5 array, then the maximum capacity is 450 GB (3 * 150 GB, the smallest disk size)
and the remaining space (300 GB) is unused.
Typical applications for RAID 10 are transaction processing, relational database applications, enterprise
resource planning and other business systems. For write-intensive applications, RAID 1 or RAID 1+0 are
probably better choices, as the performance of RAID 5 will begin to substantially decrease in a writeheavy environment.
Hot-spare
A RAID 1 or RAID 5 array with a hot-spare operates as a three-disk RAID 1 or RAID 5 array with the fourth
disk on standby. The standby disk automatically comes into play if a disk in the array fails. The
advantage of a hot-spare is that if a disk fails, then the array resynchronizes automatically with the
standby disk and operates at healthy array speed after the resynchronization.
Note: You need four hard disks installed to use RAID 10, RAID 5 or RAID 5 with hot-spare.
RAID and Data Protection
If a hard disk fails and you’re using a RAID 1, RAID 10, or RAID 5 array then your data will still be available
(but at degraded speeds until you replace the hard disk that failed and re-synchronize the array).
However, RAID cannot protect against file corruption, virus attacks, files incorrectly deleted or modified,
or the NAS malfunctioning.
