Description
The Wintec Industries WxSSxxxG1TA(I)-D1xx Endure series of ROHS Compliant Solid State Drives are constructed with
NAND-type flash memory devices paired to SandForce SF-1200 SSD controller for virtual-to-physical address mapping
and other sophisticated flash management functions. The Wintec Flash Solid State Disk (SSD) provides major
advantages over the traditional magnetic hard disk drive (HDD). Faster access time and transfer rate, silent operation
and low power consumption, better shock and vibration resistance, and lower total cost of ownership make the Wintec
SSDs an attractive choice as the next generation mass storage device.
The Endure series SSD provides high-speed data transfer and reliability utilizing SLC or MLC NAND-flash in storage
capacities ranging from 32GB to 512GB, in a small 2.5” hard drive form factor. Its robust design enables the SSD to
achieve outstanding reliability and performance. Sequential reads at up to 285MB per second and sequential writes at up
to 275MB per second, are the best in its class.
TM
With the proprietary DuraClass technology, the SF-1200 controller implements superior wear-leveling techniques and
minimizes data write amplification to ensure that the NAND flash memory is not worn out prematurely. The controller also
overcomes the flash memory ‘Read Disturb’ issues by tracking reads and refreshes data in proximity before the data is
TM
negatively impacted. The controller utilizes 24 bytes ECC algorithms and embedded RAISE
internal redundant array
to provide the protection and reliability of RAID on a single disk without any write overhead penalty to the host.
Combining intelligent bad block management, wear leveling management, read disturb management, block consolidation
and recycling, automatic data compression, AES-128 encryption, and multiple data hardening technologies, the Wintec
Endure series SSD guarantees maximum reliability and longevity of the SSD.

Architecture
The Wintec Endure series SSD utilizes a single flash controller chip with 8 parallel channels
of flash memory interface. The flash controller also simultaneously manages the file read
and write interface with the host system via a single SATA-II interface. By utilizing 8 parallel
channels of SLC or MLC flash memory, combined with internal NAND die redundancy, the
Wintec SSD can provide both high performance and reliability, while maintaining a minimal
unit cost. While other SSDs rely only upon the ECC spare area within the NAND chips to
correct inevitable bit errors within the data, the D1-series SSD has additional error correction
mechanisms, and can maintain data integrity even after complete loss of an entire NAND
flash die.

Endure (D1) Series
32GB – 512GB
1.3
Queue Depth
In order to maximize the performance potential of the Wintec D1 series SSD, a queue depth
of 32 commands is enabled when used in AHCI mode. This allows multi-threaded disk IO
requests from the host to be serviced in parallel within the drive, as well as combining small
write requests in the D1 controller’s internal buffer to minimize write amplification effects.
1.4
Data compression and Write amplification
The D1 series SSD contains an internal data compression algorithm that is processed inside
the controller’s internal processing buffer. The internal cache buffer allows for efficient data
compression without any involvement from the host or user. This data compression allows
for the actual amount of data written to the flash cells to be less than the data written to the
drive from the host, greatly extending the reliability and lifetime of the drive beyond our
competitors’ SSD products.
1.5
AES-128 Data encryption and Secure Erase
Upon initialization of the D1 series SSD, an internal randomly generated AES-128
encryption key is generated in the controller. This encryption key is not externally
accessible, which ensures integrity of the encryption key and the data that it protects. This
key is then used to encrypt all data being written to the flash. Only encrypted data is written
to the physical NAND flash chips, which ensures that any data polled straight from the
NAND flash chips is undecipherable to unauthorized parties. When an ATA Secure Erase
command is sent to the drive, the controller erases and resets the internal encryption key,
rendering the data in the NAND flash undecipherable. The data allocation map data, all
LBAs and SMART logs are also erased. The Secure Erase process takes less than 4
seconds to complete, regardless of capacity. After the Secure Erase is completed, the drive
is still functional, but the old existing data is unrecoverable.
1.6
Read disturb data loss mitigation
In typical flash read situations, reading of data in nearby cells will cause an accelerated loss
of charge from neighboring flash storage cells. The D1 series SSD tracks the number of
reads to locations within the flash and will dynamically move data that is at a higher risk of
error accumulation and data loss. If other SSD solutions do not actively manage for read
disturb effects, this will lead to much shorter data retention times.
1.7
Flash cell wear leveling
The SSD tracks the number of PE (program/erase) cycles that each block in the SSD goes
through, and will dynamically remap logical sectors written from the host to different physical
pages and blocks within the NAND flash memory. This ensures that the flash cells will wear
evenly, and that no premature wear out or data loss will occur in any portions of the drive.
1.8
Error correction and data integrity
The D1 series SSD incorporates multiple levels of error correction and data redundancy to
maintain data integrity. The D1 series uses ECC correction from the spare area on the
NAND itself, a dedicated redundant NAND flash die for parity information, as well as a data
path CRC check to ensure that data errors are detected and correctable. The redundant

Revision 1.1.2

Wintec Solid State Drive
WxSSxxxG1TA(I)-D1xx
Endure (D1) Series
32GB – 512GB
NAND flash die can maintain data integrity even after the loss of an entire NAND die. These
multiple error detection and correction mechanisms allow the D1 series SSD to maintain
lower Uncorrectable Bit Error Rates (UBER) than traditional HDD drives, throughout their
entire service lifetime.
1.9
Block recycling and Garbage collection
As data is written to the SSD from the host, the Logical LBAs do not match with the page or
erase block sizes within the NAND flash chips, which means that as the user data fills the
drive there is always some amount of data fragmentation or non-contiguous logical LBA
mapping to adjacent flash cells. This also means that invalid data is mixed into a block with
valid data. By moving and combining valid data from multiple blocks within the device, and
then writing that data to an empty block, free space can be made into whole free blocks.
This maximizes performance within the D1 series SSD, and is done internally within the
drive.
1.10
TRIM support
The D1 series SSD supports the TRIM command. Data that has been deleted from the host
can be marked as free space by the host issuing the TRIM command to the drive. This
allows the drive to more efficiently reclaim free space and maintain performance.

SATA Pin Assignment and Description
The SATA connectors are compliant with standard SATA power specifications. As is
standard, power may be supplied to all of the power pins. However, only the 5V power pins
are utilized to provide power to the SSD. Therefore, where non-standard power supplies and
connections are utilized, the power supply does not need to supply the SSD with power to
the 3.3V or 12V power pins.
