3.6 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.

4. Flash Management
4.1 Performance-optimized USB Controller
The heart of UV110-UFD5 is the USB controller, which translates standard USB signals into the data
and controls of the flash media. This proprietary USB controller is specifically designed to attain high
data throughput from host to flash.
4.2 Power Saving Implemented
The internal controller of the USB model is designed with power saving implementations, allowing the
device to operate at low power consumption.
4.3 Program RAM Architect
The internal Program RAM implementation allows the host to upgrade firmware codes anytime when
needed.
4.4 Error Correction/Detection (ECC)
UV110-UFD5 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.
4.5 Global Wear Leveling
Flash memory can be erased a limited number of times, This number is called the erase cycle limit, or
write endurance limit, The erase cycle limit applies to each individual erase block in the flash device.
In a typical application, and especially if a file system is used, specific pages are constantly updated
(e.g., the page that contains the FAT, registry, etc.). Without any special handling, these pages would
wear out more rapidly than other pages, reducing the lifetime of the entire flash.
To overcome this inherent deficiency, Apacer’s UV110-UFD5 uses Global Wear Leveling algorithm.
This algorithm ensures that consecutive writes of a specific sector are not written physically to the
same page in the flash. This spreads flash media usage evenly across all pages, thereby maximizing
flash lifetime.
The Global Wear Leveling mechanism provides write/erase cycles for reliable data storage over an
extended period.

4.6 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.

4.7 Power Failure Management
Power Failure Management plays a crucial role when power supply becomes unstable. Power
disruption may occur when users are storing data into the SSD, leading to instability in the drive.
However, with Power Failure Management, a firmware protection mechanism will be activated to scan
pages and blocks once power is resumed. Valid data will be transferred to new blocks for merging
and the mapping table will be rebuilt. Therefore, data reliability can be reinforced, preventing damage
to data stored in the NAND Flash.
4.8 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.
4.9 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.

4.10 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.
4.11 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.
