4.6 Endurance
The endurance of a storage device is predicted by Drive Writes Per Day based on several factors
related to usage, such as the amount of data written into the drive, block management conditions, and
daily workload for the drive. Thus, key factors, such as Write Amplifications and the number of P/E
cycles, can influence the lifespan of the drive.

5. Flash Management
5.1 Error Correction/Detection
SV250-300 implements a hardware ECC scheme, based on the Low Density Parity Check (LDPC).
LDPC is a class of linear block error correcting code which has apparent coding gain over BCH code
because LDPC code includes both hard decoding and soft decoding algorithms. With the error rate
decreasing, LDPC can extend SSD endurance and increase data reliability while reading raw data
inside a flash chip.
5.2 Bad Block Management
Current production technology is unable to guarantee total reliability of NAND flash memory array.
When a flash memory device leaves factory, it comes with a minimal number of initial bad blocks
during production or out-of-factory as there is no currently known technology that produce flash chips
free of bad blocks. In addition, bad blocks may develop during program/erase cycles. Since bad
blocks are inevitable, the solution is to keep them in control. Apacer flash devices are programmed
with ECC, page mapping technique and S.M.A.R.T to reduce invalidity or error. Once bad blocks are
detected, data in those blocks will be transferred to free blocks and error will be corrected by
designated algorithms.
5.3 Global Wear Leveling
Flash memory devices differ from Hard Disk Drives (HDDs) in terms of how blocks are utilized. For
HDDs, when a change is made to stored data, like erase or update, the controller mechanism on
HDDs will perform overwrites on blocks. Unlike HDDs, flash blocks cannot be overwritten and each
P/E cycle wears down the lifespan of blocks gradually. Repeatedly program/erase cycles performed
on the same memory cells will eventually cause some blocks to age faster than others. This would
bring flash storages to their end of service term sooner. Global wear leveling is an important
mechanism that levels out the wearing of all blocks so that the wearing-down of all blocks can be
almost evenly distributed. This will increase the lifespan of SSDs.
5.4 DataDefenderTM
Apacer’s DataDefender combines both firmware and hardware mechanisms to ensure data integrity.
When power disruption occurs, the hardware mechanism will notice and trigger the controller to run
multiple write-to-flash cycles to store data. Then the firmware will check that the data was correctly
written to the NAND flash after the power disruption, preventing data loss.
5.5 ATA Secure Erase
ATA Secure Erase is an ATA disk purging command currently embedded in most of the storage
drives. Defined in ATA specifications, (ATA) Secure Erase is part of Security Feature Set that allows
storage drives to erase all user data areas. The erase process usually runs on the firmware level as
most of the ATA-based storage media currently in the market are built-in with this command. ATA
Secure Erase can securely wipe out the user data in the drive and protects it from malicious attack.

5.6 TRIM
TRIM is a SATA command that helps improve the read/write performance and efficiency of solid-state
drives (SSD). The command enables the host operating system to inform SSD controller which blocks
contain invalid data, mostly because of the erase commands from host. The invalid will be discarded
permanently and the SSD will retain more space for itself.
5.7 Flash Translation Layer – Page Mapping
Page mapping is an advanced flash management technology whose essence lies in the ability to
gather data, distribute the data into flash pages automatically, and then schedule the data to be
evenly written. Page-level mapping uses one page as the unit of mapping. The most important
characteristic is that each logical page can be mapped to any physical page on the flash memory
device. This mapping algorithm allows different sizes of data to be written to a block as if the data is
written to a data pool and it does not need to take extra operations to process a write command. Thus,
page mapping is adopted to increase random access speed and improve SSD lifespan, reduce block
erase frequency, and achieve optimized performance and lifespan.
5.8 Device Sleep (DevSleep or DEVSLP) Mode
Device Sleep is a feature that allows SATA devices to enter a low power mode by designating a
particular pin as DEVSLP signal with an aim to reducing power consumption.
5.9 Hyper Cache Technology
Apacer proprietary Hyper Cache technology uses a portion of the available capacity as SLC (1bit-percell) NAND flash memory, called Hyper cache mode. When data is written to SSD, the firmware will
direct the data to Hyper Cache mode, providing excellent performance to handle various scenarios in
industrial use.

5.10 Over-Provisioning
Over-Provisioning (OP) is a certain portion of the SSD capacity exclusively for increasing Garbage
Collection (GC) efficiency, especially when the SSD is filled to full capacity or performs a heavy
mixed-random workload. OP has the advantages of providing extended life expectancy, reliable data
integrity, and high sustained write performance.
5.11 SATA Power Management
By complying with SATA 6 Gb/s specifications, the SSD supports the following SATA power saving
modes:
ACTIVE: PHY ready, full power, TX & RX operational
PARTIAL: Reduces power, resumes in under 10 µs (microseconds)
SLUMBER: Reduces power, resumes in under 10 ms (milliseconds)
HIPM: Host-Initiated Power Management
DIPM: Device-Initiated Power Management
AUTO-SLUMBER: Automatic transition from partial to slumber.
Device Sleep (DevSleep or DEVSLP): PHY powered down; power consumption ≦ 5 mW; host
assertion time ≦ 10 ms; exit timeout from this state ≦ 20 ms (unless specified otherwise in
SATA Identify Device Log).
Note: The behaviors of power management features would depend on host/device settings.
5.12 DataRAIDTM
Apacer’s DataRAID algorithm applies an additional level of protection and error-checking. Using this
algorithm, a certain amount of space is given over to aggregating and resaving the existing parity data
used for error checking. So, in the event that data becomes corrupted, the parity data can be
compared to the existing uncorrupted data and the content of the corrupted data can be rebuilt.
5.13 SMART Read RefreshTM
Apacer’s SMART Read Refresh plays a proactive role in avoiding read disturb errors from occurring to
ensure health status of all blocks of NAND flash. Developed for read-intensive applications in
particular, SMART Read Refresh is employed to make sure that during read operations, when the
read operation threshold is reached, the data is refreshed by re-writing it to a different block for
subsequent use.

6. Security and Reliability Features
6.1 TCG Opal (optional)
Developed by the Trusted Computing Group (TCG), an organization whose members work together to
formulate industry standards, Opal is a set of security specifications used for applying hardwarebased encryption to storage devices.
Hardware encryption has many advantages. First of all, it transfers the computational load of the
encryption process to dedicated processors, reducing the stress on the host system's CPU. In
addition, storage devices complying with Opal specifications are self-encryption devices. Opal
specifications also feature boot authentication. When the drive is being accessed, the shadow MBR
will request the drive password at boot. The drive will only unlock and decrypt if the correct password
is supplied. The other feature is LBA-specific permissions. Users are assigned different permissions
for LBA ranges created by the device administrator. Each LBA range is password-protected and can
only be accessed by users with the correct key to perform permitted actions (read/write/erase).
6.2 Advanced Encryption Standard
Advanced Encryption Standard (AES) is a specification for the encryption of electronic data. AES has
been adopted by the U.S. government since 2001 to protect classified information and is now widely
implemented in embedded computing applications. The AES algorithm used in software and hardware
is symmetric so that encrypting/decrypting requires the same encryption key. Without the key, the
encrypted data is inaccessible to ensure information security.
Notably in flash memory applications, AES 256-bit hardware encryption is the mainstream to protect
sensitive or confidential data. The hardware encryption provides better performance, reliability, and
security than software encryption. It uses a dedicated processor, which is built inside the controller, to
process the encryption and decryption. This enormously shortens the processing time and makes it
efficient.
6.3 End-to-End Data Protection
End-to-End Data Protection is a feature implemented in Apacer SSD products that extends error
control to cover the entire path from the host computer to the drive and back, and ensure data
integrity at multiple points in the path to enable reliable delivery of data transfers. Unlike ECC which
does not exhibit the ability to determine the occurrence of errors throughout the process of data
transmission, End-to-End Data Protection allows SSD controller to identify an error created anywhere
in the path and report the error to the host computer before it is written to the drive. This errorchecking and error-reporting mechanism therefore guarantees the trustworthiness and reliability of the
SSD.
6.4 Thermal Sensor
Apacer Thermal Sensor is a digital temperature sensor with serial interface. By using a designated pin
for transmission, storage device owners are able to read temperature data.

7.2 S.M.A.R.T.
S.M.A.R.T. is an abbreviation for Self-Monitoring, Analysis and Reporting Technology, a selfmonitoring system that provides indicators of drive health as well as potential disk problems. It serves
as a warning for users from unscheduled downtime by monitoring and displaying critical drive
information. Ideally, this should allow taking proactive actions to prevent drive failure and make use of
S.M.A.R.T. information for future product development reference.
Apacer devices use the standard SMART command B0h to read data out from the drive to activate
our S.M.A.R.T. feature that complies with the ATA/ATAPI specifications. S.M.A.R.T. Attribute IDs shall
include initial bad block count, total later bad block count, maximum erase count, average erase count,
power on hours and power cycle. When the S.M.A.R.T. Utility running on the host, it analyzes and
reports the disk status to the host before the device reaches in critical condition.
Note: Attribute IDs may vary from product models due to various solution design and supporting
capabilities.
Apacer memory products come with S.M.A.R.T. commands and subcommands for users to obtain
information of drive status and to predict potential drive failures. Users can take advantage of the
following commands/subcommands to monitor the health of the drive.

9.3 Write Protect Switch (optional)
Apacer implements the Virtual Write scheme that allows write commands to go through the flash
controller and data temporarily stored, but no data has been actually written into the flash. Once the
system is reset and rebooted, the temporarily stored data will be lost and nowhere to be found in the
system. Since the Virtual Write scheme runs at device level, it requires no software or driver
installation and is independent from the host OS.
