About this deal

did not recreate cache, as it is less than 5 days old! Created at Thu, 19 Oct 2023 16:16:59 +0200 +0.001s ... 0.001s True to its name, WD’s Blue SN550 comes with a blue PCB, in a single-sided M.2 2280 form factor, so it can fit in even the thinnest of devices. WD’s product team are fairly tight-lipped on disclosing hardware specifics enabling the Blue SN550 to perform how it does, but we managed to narrow things down a bit on our own.

I have QD 1-128 on 4K random and 128 seq results data for manufacturer comparison. Optimally, for synthetic testing, I'd do a filesize and QD sweep like I do with enterprise stuff, but for consumers, that would be a lot of data for little value. I used to plot QD1-4 and the average before, but I just don't think it is worth plotting beyond QD1 on random because one file size doesn't always relate to what real-world performance will be like. And, performance isn't hugely different between drives in QD2-4 that it matters to show. That, and I think because the application test results speak for themselves more than anything. At the end of the day, responsiveness to real-world like use is most important. SSD is designed with no moving parts to help protect against data loss if it is accidentally bumped or dropped. And with 1.75M hours MTTF (mean time to failure) 2, up to 600 TBW (terabytes written) 3, and several error correction technologies, WD Blue SATA SSDs can help guard data for years to come. 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.Most SSDs utilize DRAM or leverage NVMe’s Host Memory Buffer (HMB) feature to help accelerate Flash Translation Layer (FTL) tasks to ensure responsive performance. While the WD Blue SN500 went without DRAM or HMB and instead relied solely on a small portion of SRAM for the task, WD’s Blue SN550 adopts the feature. Windows reports a default allocation amount of 64MB of the host system’s DRAM. Let me know if you would like to see any other tests/data. I'm always looking for something new and worthwhile to add. :) Also, nice review. I was worried it might not have the synthetic benchmarks, but I was glad when I finally got to them. Personally, I care mostly about synthetics. I like when random read IOPS are tested at queue depths 1, 2, and 4, FWIW. But QD1 is what matters most. with a multi-gear ECC schemeHuh? That's the first I've ever heard of such a thing. I think that warrants an explanation.

Thousands of hours of hardware, firmware and validation testing combine to advance the award-winning WD Blue heritage of quality and reliability.A Western Digital Blue SATA SSD drive uses technology not only for higher capacities (up to 4TB in the 2.5" 7mm form factor 1) than the previous generation WD Blue SSDs, but also to help reduce cell-to-cell interference for enhanced reliability. 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). 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. As used for storage capacity, one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment.
