Introduction

I. INTRODUCTION

In the current digital environment, storage devices—especially pen drives—have become essential tools because they offer quick and portable ways to store a variety of data, such as documents, images, videos, and music. On the other hand, the widespread use of storage devices has also highlighted a serious problem: fake goods. False storage devices frequently give consumers less usable space than they claim to have. Research from eBay [1] claims that counterfeit SSDs and flash drives typically have slower access speeds and less capacity than what is advertised. Financial losses, frustration, and data loss may result from this.

ByteBuddy is a useful tool for assessing storage devices that arises in response to this growing worry. It helps users make informed decisions and protect their important data. ByteBuddy uses a thorough methodology that includes capacity verification and data transfer speed evaluation, giving users a comprehensive understanding of the device's functionality and authenticity.

II. BACKGROUND

The widespread usage of storage devices in the digital age, particularly pen drives, has given rise to a new problem: the increasing prevalence of fake goods that falsely claim to have large capacities, endangering data integrity and undermining user confidence. Fake SSD disks, SD cards, and USB flash drives are so common on the market that they put unaware consumers at serious risk [2]. Numerous freeware solutions have been created in response to this expanding problem to assist users in identifying phony storage devices and safeguarding their data [2]. One such technology is "f3 - Fight Flash Fraud," which aims to detect fake flash drives and shield consumers from purchasing phony goods [3].

Fake components affect numerous industries worldwide in addition to posing a risk to individual users. The introduction of fake parts into supply chains can result in serious problems like compromised security, and monetary losses. Research on the effects of counterfeit parts globally emphasizes how important this problem is [4]. As the market for storage devices grows, it is critical to educate consumers about the dangers of buying fake goods and to use practical tools and procedures to guarantee the legitimacy and dependability of storage devices in the digital environment.

III. OBJECTIVES

ByteBuddy addresses this challenge with a dual-fold objective:

A. Capacity Verification

1. Objective: Accurately measure usable space, identifying any disparities between claimed and actual capacity.
2. Methodology: Populate the device with pseudorandom data to detect inconsistencies, differentiating genuine from counterfeit devices.
3. Significance: Beyond countering counterfeits, ByteBuddy provides insights into device health, aiding proactive decision-making for maintenance or replacement.

B. Data Transfer Speed Assessment

1. Objective: Assess data transfer speed, a crucial factor influencing overall device performance.
2. Methodology: Measure the time taken for large file transfers, offering real-time performance insights.
3. Significance: Empower users to make informed decisions aligned with specific usage needs, optimizing their storage experience.

IV. METHODOLOGY

This program's volume test entails mounting and filling a filesystem. Although it doesn't damage anything, it needs an empty volume to work properly. Temporary test files are generated, a test pattern is written, read back, and confirmed, all during initialization. When data is written beyond the actual capacity of the disk, the test fails if the drive is phony or flawed. Temporary files are automatically cleared once the test is over, however if the drive is removed or malfunctions, user action is required. Keep in mind that writing more than the drive's capacity can harm the filesystem, necessitating a fresh reformat. The application provides an estimate of the true capacity with no accuracy guarantees, but it does not identify the type of fake. Instead, it reports faults and their locations. The volume test is file-based, so reported offsets are file offsets, not physical ones. Formatting the drive with EXFAT is recommended for accurate volume tests, as some complex filesystems may limit capacity due to metadata and fragmentation, requiring a safety buffer. ByteBuddy employs a two-fold methodology to thoroughly evaluate storage devices: capacity verification and data transfer speed assessment.

A. Capacity Verification

ByteBuddy's capacity verification is based on its ability to measure a storage device's available space with accuracy. In order to do this, the device is filled with pseudorandom data, a special data pattern that enables ByteBuddy to identify any differences between the useable space and the declared capacity. ByteBuddy can determine whether a device is authentic or fake by writing and reading back this data, which also reveals which parts of the device are unusable.

Beyond merely detecting fake devices, ByteBuddy's capacity verification is significant. Additionally, it gives consumers insightful information about the general condition and dependability of their storage devices. ByteBuddy can assist customers in proactively preventing data loss and in making well-informed decisions on device replacement or repair by recognizing faulty sectors and other potential issues.

B. Data Transfer Speed Assessment

In addition to capacity verification, ByteBuddy also assesses the data transfer speed of storage devices. This is achieved by measuring the time it takes to transfer a large file between the storage device and the computer. Data transfer speed is a crucial factor in determining the overall performance of a storage device, and it can significantly impact the user experience. Users may make educated judgments about their storage needs and usage by using ByteBuddy's data transfer speed assessment, which gives them useful information about the real performance of their storage devices. Users who save smaller files mostly might not need as high of performance, but those who transfer huge files frequently will benefit from devices with quicker transfer speeds.
