Waitan's Waitan's advanced
technology and manufacturing process maintains highly reliable
results, ultra fast and secure SSD and flash hard drive modules
for customers with different needs, especially in industrial,
enterprise and special computing applications. Some major
advanced technologies implemented in Waitan's solid state drive
include:
1. Wear Leveling Technology
NAND flash has individually erasable blocks, each of which can
be put through a finite number of erase cycles before becoming
unreliable. After a specific number of cycles for each block,
the error rate can significantly increase. Unfortunately, in
most cases, the flash media is not used evenly. In certain
areas, such as for the file system, the data is updated more
frequently than for other areas and will wear out sooner in
those areas. Wear leveling eliminates this issue by arranging
data so that erases and re-writes are distributed evenly across
the entire device. This way, no single sector prematurely fails
due to a high concentration of program/erase cycles. Waitan uses
an advanced wear leveling algorithm, which can efficiently
spread usage throughout the entire flash media area. By
implementing both dynamic and static wear leveling algorithms,
the life expectancy of the flash media can be improved
significantly.
2. Error Detection / Correction
Waitan's solid state drives implement the BCH ECC Algorithm, one
of the most powerful ECC algorithms in the industry. This
algorithm can correct up to 12 random bit errors in each 512
byte area.
3. Bad Block Management
Bad blocks are blocks that contain one or more bits for which
the reliability is not guaranteed. Bad blocks can occur when the
flash is shipped or can develop during usage. Waitan implements
an efficient bad block management algorithm in the solid state
hard drive to detect factory produced bad blocks as well as
those that develop over the lifetime of the device. This process
is completely transparent to the user through the use of
S.M.A.R.T. command tools so the user will not be aware of the
existence of the bad blocks during operation.
4. S.M.A.R.T. Technology
S.M.A.R.T. stands for Self-Monitoring Analysis and Reporting
Technology. S.M.A.R.T. was developed by a number of major hard
disk drive manufacturers to increase the reliability of hard
drives. This technology enables the PC to predict the future
failure of hard disk drives. S.M.A.R.T. has become an industry
standard for hard drive manufacturers, and now S.M.A.R.T. has
also been incorporated into Waitan's SSDs. Through the S.M.A.R.T.
system, our solid state disk incorporates a suite of advanced
diagnostics that monitor the internal operations of the drive
and provide an early warning for many types of potential
problems. When a potential problem is detected, the SSD can be
repaired or replaced before any data is lost or damaged.
S.M.A.R.T. monitors SSD performance, detects faulty sectors,
performs recalibration and CRC error correction, etc. For more
information on Waitan's S.M.A.R.T. implementation and command
descriptions, please refer to our datasheet.
5. NCQ Technology
NCQ stands for Native Command Queuing technology. NCQ technology
allows the drive to manage multiple outstanding commands more
efficiently, which significantly increases concurrent access
capability. It solves the concurrent access bottleneck
associated with traditional HDDs in some high concurrent access
applications such as on-line banking, on-line ticketing and VOD.
As part of the latest Serial ATA specification, NCQ requires an
NCQ-capable SSD and either a motherboard or a PCI adapter card
with NCQ support. NCQ technology is incorporated into select
SSDs from Waitan.
6. Other SSD Technologies
Other Waitan SSD technologies include compliance with RAID,
power down protection for data writing, hot plug support, secure
erase, hardware encryption, write protect and active garbage
collection technologies that bring Waitan the world's top grade
SSDs.
7. High Reliability Manufacturing Systems
Since enterprise, industrial, and mission critical applications
require much more reliable devices than typical consumer
products, a more sophisticated production management system is
necessary to meet commercial and industrial customers'
requirements. The key to providing reliable devices is a product
traceability and failure analysis system. Waitan's manufacturing
systems are ISO9001 and ISO14001 certified. Our SSD products are
FCC, CE, MIC, RoHS and UL certified. In addition, we also have
implemented statistic process control and document control on
the manufacturing floor together with monthly and quarterly
internal audits that ensure a controlled quality environment to
produce highly reliable products.
