Table 3-1 Capacity Specifications Capacity Total bytes Total LBA 128 GB 123,924,905,984 242,040,832 256 GB 247,895,949,312 484,171,776 Notes:  Display of total bytes varies from operating systems.  1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.  LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of the device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small portion of the capacity is reserved for device maintenance usages. 3.2 Performance Performance of UV110-UFD7 is listed below in Table 3-2.

Serving as statistical reference, the prediction result for Apacer’s UV110-UFD7 is more than 3,000,000 hours. Note: The MTBF is predicated and calculated based on “Telcordia Technologies Special Report, SR-332, Issue 3” method. 3.5 Certification and Compliance UV110-UFD7 complies with the following standards:      CE UKCA FCC RoHS Recast Compliant MIL-STD-810G 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. Table 3-4 Endurance Specifications Capacity Drive Writes Per Day 128 GB 2.74 256 GB 2.74 Notes:  This estimation values are based on sequential write behavior. (Apacer EDTestTool, test mode –sequential data pattern -100.00% of disk space with 128K)  Flash vendor guaranteed 3D NAND TLC P/E cycle: 3K  WAF may vary from capacity, flash configurations and writing behavior on each platform.  1 Terabyte = 1,024GB  DWPD (Drive Write s Per Day) is calculated based on the number of times that user overwrites the entire capacity of an SSD per day of its lifetime during the warranty period. (3D NAND TLC warranty: 3 years) 5 © 2022 Apacer Technology Inc. 4. Flash Management 4.1 Performance-optimized USB Controller The heart of UV110-UFD7 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-UFD7 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-UFD7 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. 6 © 2022 Apacer Technology Inc. 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. Table 4-1 SMART Attribute ID List ID (Hex) Attribute Name 162 (0xA2) Spare Block Count 163 (0xA3) Maximum Erase Count 164 (0xA4) Average Erase Count 166 (0xA6) Total Later Bad Block Count 167 (0xA7) Protect Mode 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. 7 © 2022 Apacer Technology Inc. 4.10 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. 8 © 2022 Apacer Technology Inc. 5.
