WD_BLUE SN550 1TB M.2 2280 PCIe Gen3 NVMe up to 2400 MB/s read speed

Product Information

TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity. Almost looked like there was solder rework done by a rookie. I would have gotten more than my wrist slapped if I'd left something like that in one of our downhole tools. Flux can cause electrical leakage at higher temperatures.

With a certification from the WD Functional Integrity Testing Lab (F.I.T. Lab™), every WD Blue SATA SSD is verified for compatibility with a wide range of desktop and laptop computers. The Western Digital Dashboard helps users maintain peak performance of the Western Digital SSD in Windows operating systems with a user-friendly graphical interface for the user. The Western Digital Dashboard includes tools for analysis of the disk (including the disk model, capacity, firmware version, and SMART attributes) and firmware updates. bit_user said:I hadn't noticed. I feel like it'd give a more intuitive sense of what happens to transfer speeds over time, if it were linear in both X & Y. Just my opinion.techgeek said:Looks like they need a little quality control over at WD. Look at all the flux left on the bottom right-hand corner (from the perspective of the picture) around all the SMD caps and diode near what I believe is the controller. Amazing that made it out of the factory like that.=========================================== As used for transfer speed, megabyte per second (MB/s) = one million bytes per second. Performance will vary depending on your hardware and software components and configurations. The WD Blue SN550 NVMe SSD(WDS100T2B0C-00PXH0) is a good priced NVMe SSD for M.2 slots (2280). It features no DRAM buffer memory and uses 3 bit TLC memory chips with 96 layers. Officially Western Digital states 2.4 / 1.95 GB/s read / write speeds that we also could measure with CDM6 (2443 / 2019 MB/s). bit_user said:Huh? That's the first I've ever heard of such a thing. I think that warrants an explanation.

Actually, that is probably underfill for the controller which is a small CSP chip. Considering the position (close to the connector) and the size/ type of the chip, the underfill is probably laid to protect against stress (thermally induced and mechanically from insertion).Looks like they need a little quality control over at WD.
