Crucial P3 Plus 4TB PCIe 3.0, 3D NAND, NVMe, M.2 SSD, up to 5000MB/s - CT4000P3PSSD8

Product Information

The AHCI (Advanced Host Controller Interface) command protocol was designed for much slower media (i.e., spinning magnetic disks). AHCI is inefficient with modern SSDs, so a new standard was developed: NVMHCI (Non-Volatile Memory Host Controller Interface). Combine NVMHCI with a fast PCIe interface, and you have NVMe, Non-Volatile Memory Express. It's a much-improved interface developed around the needs of flash memory rather than spinning disks. What's NVMe performance like in the real world? For most PC applications, that probably doesn't matter. But for small form factor rigs and perhaps a gaming laptop, every little can undoubtedly help. On that note, for most applications, we'd probably go for the cheaper bare drive rather than this more expensive model with its heat spreader. The revised SN850X is inherently a cooler-running thing, after all. In many other regards, this X model is a dead ringer for the SN850. We’re talking four lanes of PCIe Gen 4 connectivity in the now ubiquitous M.2 2280 form factor. But the 1TB model reviewed here is now the entry-level option. There’s no longer a 512GB model. What’s more, WD’s in-house controller chip, provided by compatriot SanDisk, has been revised, though detailed specifics aren't provided.

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. Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you.

It comes in at 75MB/s read and 291MB/s, which is in the mix with some of the faster Gen4 and first-wave Gen5 drives we've tested. The combination of the Phison E18 controller and 176-layer TLC flash from Micron is a match made in heaven: unrivaled peak performance and, with the right cache design as on the Gaming model, strong sustained performance. That is ideal for workstation tasks, and Inland’s drives are cheaper than competitor offerings while maintaining a decent warranty. This is a barebones drive but will get the job done.

In need of a lot more storage capacity? Look no further than the Lexar NM790. Available with up to four terabytes of storage, there's really no need to worry about your burgeoning Steam library any longer with one of these installed in your PC. 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. GB/s is here to stay with the introduction of Teamgroup’s Cardea Z540 SSD. It set multiple records in our testing, beating out even the very fast Crucial T700. If you want the best storage performance possible right now, this drive is it. Its consistent sustained performance and DirectStorage-optimized firmware are additional bonuses, making it a great choice for high-end desktop gaming or workstation tasks. Faster drives are on the way, including Team’s own Z54A, but with a slowing storage market this is the king for now. 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. 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 XS70 is designed with PS5 compatibility in mind so the heatsink isn’t as bulky as some others you might come across. It really does look good. Admittedly I'm talking about an SSD here, and its not the kind of thing you'll spend time looking at, but Silicon Power's designers deserve credit. The main way it achieves this is by being a DRAM-less SSD drive. This saves a big chunk of the manufacturer's bill of materials, and thanks to advances in the latest controllers, it can be surprising how little impact this has on performance. Such drives are slower, don't get me wrong, but this new SN770 still quotes read and writes of 5,150MB/s and 4,900MB/s, respectively. Not bad.

Rather more specific to this WD drive is the latest 2.0 version of the company's Game Mode drive management software. WD claims it improves game loading times courtesy of a so-called "read look-ahead" algorithm, which predictively caches game data. It now runs automatically, detecting when games are loaded. How much that kind of feature actually makes a difference in the real world is notoriously difficult to pin down. But it's unlikely to be revolutionary.has become a more attractive capacity point for SSDs as time has gone on. While there are now many options available, most come with compromises of one sort or another. You may have to settle for QLC, a weaker controller, no DRAM, unreliable hardware, etc. This is not always a big deal, especially if the drive is intended to be a secondary gaming drive. In the PlayStation 5, however, extra cooling is beneficial, so it’s convenient to have a heatsink option available. At the same time, laptops favor bare drives and especially single-sided drives, the latter of which have been very rare with TLC until recently.
