Furthermore, the SN850 shines when integrated with a PlayStation 5, registering read speeds of about 6,550MB/s, enhancing game load times on the PS5 over integrated console storage.

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. We mentioned NVMe above. NVMe is another technical hurdle to consider, because systems and motherboards need board-level support for these drives to be bootable. All late-model motherboards now support NVMe M.2 drives, but older boards are not guaranteed to support booting from an NVMe-based drive. Outside of new motherboards, these high-bandwidth, NVMe-capable slots are also found in some recent laptops. Also note that in some cases, a laptop may support a PCI Express NVMe drive, but it may be soldered to the motherboard and thus not upgradable. So, if you're thinking of upgrading a recent laptop or convertible, be sure to consult your manual very closely before buying one of these drives.

This makes it adept at handling rigorous tasks like video editing, game loading, and more. 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. A range of capacities from 1TB to 4TB(2) means you get to keep more of today’s games that can take up 200GB(2) or more of storage.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. That's not a bad thing. Especially in the case of laptops, an older machine might supportonlyM.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.

Before you open your wallet, be sure to prepare for this drive: it requires a heatsink to reach its highest levels of performance. Unlike with the T700, Team does not offer a heatsink version of the Z540. The heatsink requirement mostly precludes it from use in a laptop, and you can choose from less expensive options for the PlayStation 5. In fact, there are many solid Gen 4 alternatives that are much more budget-friendly without some of the Z540’s downsides, like its poor power efficiency. But if you want the very best performance right now, look no further. The market has settled on 22mm wide as the standard for desktop and laptop implementations; the aftermarket drives available and the accessible slots we've seen have all been that width. The most common lengths we've seen are 80mm ("Type-2280") and 60mm ("Type-2260"). The lengthier the drive, the more NAND chips you can tend to stuff on it (plus, M.2 drives can be single- or double-sided), though know that length isn't an absolute measure of capacity. 42mm, 60mm, and 80mm M.2 SSDs (Credit: Intel) 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.

M.2 Upgrades and Boot Drives: What to Look For

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. At the core, an SSD is just a thin circuit board studded with flash-memory and controller chips. Why not design around that? Thus the M.2 form factor was born. But we're getting ahead of ourselves. Its random read/write operations aren’t the best among PCIe 4.0 SSDS, so this SSD is best suited for loading very large files like video games, large media files, or as a boot drive.

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. Though it can't quite match the gaming prowess of some of the latest generation of PCIe 4.0 speedsters, the 990 Pro with Heatsink still offers respectable gaming performance while being a thoroughbred workhorse for creative tasks. It's an appealing choice and a worthy upgrade from the 980 Pro. If you're a custom PC builder with RGB-lighting fever, and have RGB-ified just about every inch and corner of your system, perk up: ADATA has brought pretty lights to the internal SSD final frontier. The XPG Spectrix S40G is the most flamboyant NVMe drive we've seen to date. With its exceptional 4K write speeds, top-notch sequential-read speeds, and respectable durability rating, ADATA makes having a top-of-the line, over-the-top SSD affordable and fun, in one fell swoop. Who It's For Reliable Brand: Western Digital is a trusted name in storage solutions, known for its quality and reliability. The PNY XLR8 CS3140 M.2 SSD is one of the best SSDs around, both for gamers and PC enthusiasts alike. Available in three capacities—1TB, 2TB, and 4TB—this SSD is a great swan song for the PCIe 4.0 era as PCIe 5.0 SSDs start to roll out.However, it's essential to note that the SN850 runs hot under load, so a heatsink is advised (which can increase its price), but it's a great option for PS5 owners and PC gamers alike. Our tests reflect this for the most part, recording a sequential read speed of 7,256MB/s in CrystalDiskMark 8, with a somewhat lower than expected sequential write speed of 6,082MB/s in the same test. Interestingly though, it had the highest random write performance of any drive we tested (4,938MB/s), including the vaunted Samsung Pro 990, which had a roughly 17% slower random write rate (4,105MB/s). It also had the best average data copy rate of all the drives we tested recently with 1,733MB/s, so this is not only a great gaming SSD, it’s a fantastic all around performer at a great price.

Finally, we use the drive as our primary SSD in our workstation PC (and video game console, if appropriate) to assess the real world use of the drive. While the PCIe 5.0 drives are the fastest SSDs money can buy right now, believe it or not, raw speed isn't everything. In regular productivity tasks such as web browsing or light desktop work, you may not even notice the difference between a PCIe 3.0 SSD and one with a 4.0 interface, let alone a new bleeding-edge PCIe 5.0 model. The latest PCIe 5.0 SSDs also carry a heavy price premium for now, so you're probably best suited with a PCIe 4.0 or 3.0 model — unless you're after the fastest possible performance money can buy, of course. If that's the case and your system supports it, go for a new PCIe 5.0 SSD.Efficient Cooling: The inclusion of a heatsink ensures that the SSD maintains optimal temperatures, preventing thermal throttling and sustaining high performance during prolonged usage. This feature is particularly beneficial for gaming and demanding applications. If the drive is compatible with a video game console, we will also measure the SSD's speed both with the console's own benchmarks but also through file copy operations to and from the main console storage drive.
