I am aware of the distinctions, I thought it would be obvious from the context.
I meant to compare a 2x m.2 NVMe RAID0 with dedicated NVMe add-in cards, e.g. a kingston dcp1000. The latter can outperform the former per unit but seem more expensive even when you adjust for the higher stats.
- dragontamer 9y agoI think I see what you mean now. M.2 NVMe drives are electrically PCIe 3.0 x4 lanes. Since laptops are such a popular form factor, it seems like all the best technology and mass-production is favoring M.2 drives. Its clear to me that older physical PCIe drives are just going obsolete in terms of price/performance now. PCIe drives (the ones that physically went into a x4, x8, or x16 slot) are a dinosaur at this point. It seems like the "serious" datacenter technology is converging upon U.2 drives (which are also PCIe 3.0 x4 slots, except over a cable). Its been a bit rocky these past few years: Sata-Express (2x PCIe), U.2, M.2 SATA, M.2 NVMe, and "physical PCIe" SSDs. But the industry is finally converging into something of a standard. M.2 NVMe is the high-performance part for consumers, especially the laptop market. While U.2 for servers who need large capacity and benefit from the physical presence of a wire connection.
- baldfat 9y agoTook me a bit to understand what you are saying. The 3700 mb read is what I am intrested in exactly. I really think we are going to have some foundamental change in chip design to make 5K video and 8K (For commercial video it will be 15-20 years until 8K will be common in personal use.
