Reduced operating temps are another clear benefit of this new drive. The old SN850 hit a toasty 77°C. The new drive hits just 58°C under sustained load. That's a very worthwhile improvement. Elsewhere, the gains are less obvious, albeit the SN850 was already a great drive. The 4K random access results are a little disappointing, showing little to no improvement. Likewise, don't expect big gains in system-wide measures of performance like PCMark 10.

The SK hynix Gold P31 is still the gold standard for laptop SSDs, especially as it has DRAM, but it’s limited to PCIe 3.0 bandwidth, isn’t always available, and is limited to 2TB of capacity. The MP44 can get twice the bandwidth, but even in a 3.0 slot, it is inexpensive for 4TB and even has an 8TB option. Other alternatives, like the Crucial P3 Plus or Corsair MP600 Core XT, are slower and use QLC. The heatsink found on the Addlink A93 and other SSDs preclude them from laptop use and can add a little cost. Otherwise, the MP44 will have some competition at lower capacities, but it is worth a look if you can find it at the right price. Running on the same basic interface as your graphics card, NVMe SSDs deliver more raw bandwidth and performance than any SATA-based SSD could ever offer. They're also a lot smaller than any other hard drive or SSD too, which all means that the best NVMe SSDs are perfect for either that small form factor build you always wanted or a monstrous high-end gaming PC build. What PCIe generation should I look for? 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.

Many of the first PCIe 5.0 SSDs come with active cooling solutions, meaning they have a fan attached to the heatsink. In contrast, the T700 has a stylish passive heatsink that does an admirable job of assuring top-notch performance. Crucial also offers the drive without a heatsink, thus allowing you to use either your own third-party cooler or the in-built motherboard M.2 heatsinks that are becoming increasingly popular. 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. 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. Silicon Power is a brand that probably doesn’t get much attention compared to the likes of Samsung or WD, but when you look at its XS70 NVMe SSD with its high-end specifications, it's clear that the brand name isn't everything. Armed with the latest Phison controller and high-performance NAND flash memory, a drive like the Silicon Power XS70 should have no problem competing with thebest SSD on the market. 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.The point is, there's not much this Lexar drive can't do, and for a good price. If you have a spare Gen4 slot in your machine, and you are desperate for more game storage space, I highly recommend you look to the Lexar NM790 to fill that slot. 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.

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. 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. 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? SK hynix’s Gold P31 is great if you’re looking to increase your laptop storage, not only to gain capacity but to gain battery life, too. While some drives may perform well against the Gold P31 in benchmarking, the SK hynix is much more power-efficient, which will lead to longer off-the-charger sessions. Laptop users who prioritize battery life should definitely put the new SK hynix Gold P31 at the top of their drive list. Additionally, the Gold P31's very strong write performance and ultra-high efficiency make it a well-rounded choice for many desktop users as well. The Lexar does differ from many others we've looked at. We've come to expect higher-end Gen4 drives to rely on Phison's very popular E18 controller, but the Lexar doesn't. It uses a MaxioTech MAP1602A controller, a less known quantity in the US and EU markets. This makes for overtly different behaviour in testing to more common controllers, but not in a bad way.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. Finally, on the speeds and feeds, this 2TB drive is rated at 1,200TB for write endurance. As it happens, that's precisely the same as the new Samsung 990 Pro 2TB. But it's also far from some other competing M.2 SSDs. 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. 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.

For one, this drive is cool under load. When transferring over 200GB of data in one steady stream, which you may not do all that often in real-world use, we measured the temperature at 72°C. That's an admirable temperature from a drive with no active cooling solution and high speeds. It improves game loading times courtesy of a so-called "read look-ahead" algorithm, which predictively caches game data. 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. It's great if your desktop system can handle a PCIe 5.0 drive, but they are still new and expensive, so they aren't a requirement: For example, the PCIe 4.0 Samsung 990 Pro is our current choice for the best SSD overall, and the best SSD for gaming. This drive is rated for 7,450 / 6,900 MBps of sequential read/write throughput and 1.2 / 1.55 million read/write IOPS. That means less time waiting for game levels to load or videos to transcode, not to mention a snappier experience in Windows. The Team MP44 is part of the vanguard for new and better DRAM-less SSDs. Newer controllers and flash are letting budget/value drives push the limits of the PCIe 4.0 interface while providing high capacities without making compromises. They can have the endurance and performance of TLC and the high power efficiency of four-channel, DRAM-less controllers, all without extra cost. Less power means less heat, and these drives are also designed to be single-sided. That combination makes the MP44 perfect for laptops.

In our tests, the Intel 670p loaded Final Fantasy at the same speed or faster than competitors. It also finished just two places below the vaunted PCIe 4.0 Samsung 980 Pro in PCMark 10. Those are very respectable marks for a budget drive. It's worth noting that this drive can get hot when pushed, just like the SN850. It hit 76°C after a long day of testing, but without direct cooling on it, not even a heatsink. It should be fine in most systems, especially if your motherboard does come with some cooling solution. It's also pretty speedy in random workloads, which will make for a snappier system. 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. Well, it's got it all if the context is PCIe 4.0 drives. There is a new generation of PCIe 5.0 drives but they're a bit over the top for most gamers right now. PCIe Gen 4 is not only where it's at, it's probably also the limit of your PC or laptop's capabilities.The era of PCIe 5.0 SSDs is upon us, propelling us to new heights of stratospheric SSD performance. Blazing-fast PCIe 5.0 M.2 SSDs, which offer up to twice the sequential speeds of the older PCIe 4.0 standard, are now supported with Intel and AMD's current platforms, the Zen 4 Ryzen 7000 and 13th-Gen Raptor Lake.
