![]() Hello, I’ve just been comparing a 512GB 951 NVMe variant that I purchased yesterday with an existing 512GB 951 AHCI. The XP941 came with another product, but we have a brown box pic for that one: ![]() I liberated it while he wasn't looking (shhh). The AHCI SM951 came in a 2015 Lenovo X1 Carbon that Ryan has been testing. Our NVMe SM951 was 'packaged' with another product we got in for testing. * We know the NVMe SM951 has higher specs than what was stated in our source, but we don't have more accurate figures from Samsung. Peak Random Performance Writes: 60k, 72k IOPS.Peak Random Performance Reads: 120k, 122k IOPS.Peak Write Sequential Performance 800, 931 MB/s *.Peak Read Sequential Performance: 1.08, 1.17 GB/s *.Flash: Samsung 16nm MLC (verified visually).Peak Random Performance Writes: 70k IOPS.Peak Random Performance Reads: 90k IOPS.Peak Write Sequential Performance 600, 1200, 1500 MB/s.Peak Read Sequential Performance: 2050, 2150, 2150 MB/s.Power Consumption (Active/Idle): 6.5W / 50mW.Peak Random Performance Writes: Up to 72k IOPS.Peak Random Performance Reads: Up to 122k IOPS.Peak Write Sequential Performance: Up to 930 MB/s.Peak Read Sequential Performance: Up to 1170 MB/s.Power Consumption (Active/Idle): 5.8W / 80mW.Uncorrectable Bit Error Rate (UBER): These are all OEM products, but here are some specs from various sources: I'll be comparing the three above units against some other PCIe SSDs, including the Intel SSD 750, Kingston HyperX Predator, G.Skill Phoenix Blade, Plextor M6e Black, and more!Ĭontinue reading our review of these hot new M.2 products! That new variant did finally end up launching, and we have rounded it and the other Samsung M.2 PCIe SSDs up for some much awaited testing: Sitting back for a few months was a wise choice in this case, as an NVMe-only version would limit the OEM products that could equip it. We can only assume that Samsung chose to hold back on their NVMe-capable iteration because many devices are unable to boot fron an NVMe SSD. It was supposed to launch as an NVMe product, but ended up coming out in AHCI form. There's been a lot of recent talk about the Samsung SM951 M.2 PCIe SSD. Introduction, Specifications and Packaging We got our hands on an NVMe SM951! How does it stack up? ![]() Conclusion, Pricing, and Final Thoughts.Random Performance – Iometer (IOPS/latency), YAPT (random).Sequential Performance – HDTach, HDTune, File Copy, YAPT (sequential).Internals, Testing Methodology and System Setup.We got our hands on an NVMe SM951! How does it stack up?.Introduction, Specifications and Packaging.This SSD only works with Thunderbolt 3 ports, and while the previous market segment can easily understand that, the second segment can increase the customer support workload. That said, one aspect that makes devices like Patriot Evlvr (and other low-cost Thunderbolt 3 SSSs that will use Alpine Ridge controllers) that are hard to sell is incompatibility with the generic Type-C USB ports. The Patriot Evlvr is one of the first portable Thunderbolt 3 SSDs to target the last segment. The first requires extreme performance, and is willing to pay a premium price for it - Devices like Sonnet Fusion, LaCie Bolt3, TEKQ Rapide, and our DIY configuration with PCIe 3.0 x4 NVMe SSD (SanDisk Extreme Pro M.2 NVMe 3D SSD with TEKQ Rapide enclosure) the target market. We believe that the target market for Thunderbolt 3 SSDs can be split into two - one belonging to the professional content-making market where time is money, and the other is the average consumer who just wants a portable hard drive fast and just read to pay the small premium over USB based flash drive such as Samsung Portable SSD T5 or SanDisk Extreme Portable SSD. On a per-GB basis, this translates to Evlvr being the most affordable Thunderbolt 3 SSD we have tested. The last aspect to note is price fixing - Patriot announces that the 1TB variant of Evlvr will sell for $ 490.
