НЕ покупайте ЭТОТ дешевый SSD! ↪︎ Somnambulist H650

Looking for the cheapest 128GB SSD for your laptop or PC? In this video, we'll provide a detailed technical breakdown of the popular, affordable Somnambulist H650 128GB Solid-State Drive (SSD) from AliExpress. You'll learn why this drive is a dangerous gamble, hiding used components, and why the actual write speed drops below that of an old USB flash drive. We'll open the case, show the hardware (controller and flash memory) of this budget drive, run stress tests using benchmarks, and explain why buying no-name drives leads to data loss and Windows freezes. Technical Specifications and Hardware At the initial S.M.A.R.T. analysis using diagnostic software, everything appears standard. But a hardware disassembly reveals severe cost-cutting: Memory controller: Yester YS9082HP DRAM-less controller (a budget solution from Maxio/Yester, often used in cheap Chinese drives). Memory type (NAND Flash): Two memory chips with the original markings intentionally laser-erased. This is a clear sign of the use of "second-best" memory—rejects from large semiconductor factories or used (refurbished) chips. Drive datasheet: HP2215A2 firmware is detected, with a batch serial number of 2024. Victoria and SSD-Z utilities show a "GOOD" status and correct TRIM operation, but this is merely a software mask. Performance Test Results (Benchmarks) We tested the Somnambulist H650 in popular benchmarks for SATA III read and write speeds: Linear Read: Stable 408 MB/s on average, with no significant dips. Linear Write Test (AIDA64 Disk Benchmark): Major dip. After filling the minimum pseudo-SLC cache, the speed drops to a catastrophic 2.36 MB/s! The drive becomes unstable. CrystalDiskMark: Sequential Write shows a drop to 22 MB/s. ATTO Disk Benchmark: Constant fluctuations in write speed amplitude are observed, indicating overheating or the YS9082HP controller's inability to handle the data flow to the poorly functioning NAND flash. Frequently Asked Questions about Ultra-Low-End SSDs (FAQ): Can the Somnambulist H650 be used with an operating system? No. With Windows background tasks (updates, browser caching), the speed will drop to 2 MB/s, and the system will freeze. What does faded markings on memory chips mean? This means the manufacturer used defective silicon wafers or used memory chips (low-grade chips) that failed quality control at major brands (Samsung, Micron, Hynix). What is the risk of data loss? Maximum. Unbuffered controllers paired with degraded memory are prone to sudden "bricking" (the drive enters write-protect mode or becomes unrecognized in the BIOS).
