The newest budget NVMe SSDs have undercut the pricing of mainstream drives on the slower SATA interface (which was originally designed for hard drives), but we shouldn't expect to see the end of SATA SSDs any time soon.

PCI Express NVMe Solid State Drives (SSDs) for 2023 The Best PCI Express NVMe Solid State Drives (SSDs) for 2023

Welcome to the cutting edge! You're shopping for a kind of drive that many folks don't even realize exists. As a result, you need to pay attention to several factors that may not be documented very well while you shop. Let's recap. Right now, PCIe 4.0 is the go-to PCIe generation. That's because it offers a high speed at a reasonable cost. The newest SSDs on the market offer PCIe 5.0 capability, which doubles the theoretical bandwidth an SSD can run at. However, these are few and far between and awfully expensive. Also the first drives of any PCIe generation tend to end up much slower than what that generation is truly capable of.The Solidigm P41 Plus is the best budget DRAM-less M.2 NVMe SSD on the market. It’s particularly good at 2TB, rivaling the 670p, which is older but comparable. This is no surprise as Intel’s NAND and SSD division migrated to Solidigm after a sale of the company to SK hynix, so the P41 Plus is reminiscent of that excellent budget drive. We would give the edge to the P41 Plus if you can make full use of the drive, which includes total Synergy 2.0 SSD driversupport. We’d also give the P41 Plus the edge over the P3 and P3 Plus if you’re shopping for your primary drive, as it has more consistent performance, even if maximum bandwidth is lower. This isn't a slow SSD, either. It's right up there with the very best PCIe Gen4 drives today at 7,400MB/s read and 6,500MB/s write. In our own testing, we measured it at 7,106MB/s seq. read and 6,504MB/s seq. Write—very nearly bang on what's advertised, which is really great. The synthetic performance shows the SN770 trails more expensive drives in terms of reads, although the writes are much closer. The 4K performance is relatively impressive and shows that the SN770 has something to offer in this crowded marketplace. It's not too surprising that this drive outperforms Samsung's DRAM-less offering, as that is a PCIe 3.0 drive, after all, but the extent to which it does is impressive. As we discuss in our parallel roundup, The Best M.2 Solid-State Drives, M.2 drives are differentiated by a four- or five-digit number listed in their names or specifications. The number is a measurement in millimeters, with the first two digits being the drive's width and the remaining two or three digits telling you how long it is.

SATA is slowest: SATA isn't as fast as an M.2 PCIe or a PCIe add-in card, but the majority of desktops and many laptops support 2.5-inch SATA drives, and many doing typical mainstream tasks users won't notice the difference between a good recent SATA drive and a faster PCIe model. That's not a bad thing. Especially in the case of laptops, an older machine might support only M.2 SATA-bus SSDs, and that will be the boundary of your upgrade path...end of story. As a result, the only reasons you'd upgrade the drive, in that situation, would be to get more capacity, or if the old one failed. The ADATA XPG Spectrix S40 is an unapologetically bright RGB-lit PCIe 3.0 NVMe M.2 SSD that blings up your PC. Its 4K read and write speeds should keep most gamers happy, too. The ADATA XPG Spectrix S40G carries some respectable wins out of its duel with other competing drives we've tested, and it looked great doing it. The Intel 670p is an older driver, but it is also a proven budget option that is often on steep sale. It’s best to grab it at 1TB or 2TB, as the 512GB model is slower with a smaller pSLC cache. The drive has DRAM, which is nice, and it has the fastest QLC on the market, even now. Performance outside of the cache does not suffer as much as a consequence. Some PCI Express M.2 SSDs can run hot under sustained use, so having the M.2 module mounted on a vertical card can also mean better ventilation, and in theory less throttling due to heat. That said, these drives are so fast that under most normal use they finish data transfers before heat can become a major issue.The WD Red SN700 doesn’t offer anything special for the general user, but is great for use in a NAS. The underlying technology is also starting to show its age, but that maturity is important for critical storage systems like a NAS where performance isn’t as much of a focus. The WD Red SN700 also doesn’t have power loss protection, although that isn’t surprising as this drive isn’t for an enterprise application. However, the warranty and rated endurance are strong, which makes this a good buy for the right usage, which in this case is in a NAS. It improves game loading times courtesy of a so-called "read look-ahead" algorithm, which predictively caches game data. Of course, SK Hynix isn't new to this space, but the new P41 is arguably the brand's first tilt at a truly high-end M.2 drive. The old SK Hynix Gold P31 was a bit of a clunky old thing, limited as it was to the PCIe 3.0 interface and a controller chip with a mere four memory channels. The new Platinum P41? It's got it all. As for the actual flash memory used, it's SK Hynix's latest and very greatest 176-layer 3D TLC NAND. It's about as advanced as TLC memory currently gets, and SK Hynix claims a 40% performance boost over its old 128-layer chips. The net result is sequential read and write specs for this 2TB model of 7,000MB/s and 6,500MB/s respectively. Intel is a known brand, and their SSDs are generally reliable, with a strong warranty and good support. However, this drive now falls under the Solidigm umbrella and has been succeeded by the PCIe 4.0 P41 Plus. That drive is DRAM-less and feels more like a side-grade, but has also been priced aggressively. However, if you don’t need the bit of extra bandwidth and would prefer a drive with DRAM, the 670p is a solid choice for a budget PCIe 3.0 SSD, especially for laptops.
