SABRENT M.2 NVMe SSD 4TB Internal Solid State 3450MB/s Read, PCIe 3.0 X4 2280, M2 Hard Drive High Performance Compatible with PCs, NUCs Laptops, and Desktops (SB-ROCKET-4TB)

Product Information

Know which bus you're on. In a laptop-upgrade scenario, you're almost certainly swapping out one M.2 drive for another, with the intent of gaining capacity. Make sure you know the specifications of the drive coming out of your system—and whether it's reliant on the SATA or PCI Express bus—so you can install the same, presumably roomier kind going in.

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. The PCIe 5.0 SSDs still have plenty to offer. The Crucial T700 is unquestionably the fastest consumer SSD in the world that you can actually buy, at least for now, delivering up to a blistering 12.4 GB/s of sequential throughput and 1.5 million random IOPS over the PCIe 5.0 interface. That's an amazing level of performance from an amazingly compact device. 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. We also make sure to measure the SSD's heat and controller-reported data on how much data has been written to the drive and how much life the drive has left before failing to determine whether the manufacturer's claimed endurance measures up to the time the drive itself estimates it has left.Yes, faster drives will be released to the market near the end of the year, but for now, the T700's 12.4 / 11.8 GB/s of throughput leads the market, not to mention the beastly up to 1.5 million random read/write IOPS that remains uncontested by any SSD on the market. The Crucial T700 can take a beating, too: The T700 doesn't lose as much steam as other drives during heavy sustained workloads, making it a suitable drive for even the heaviest of workloads, like workstation-class video editing. 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. (Credit: Zlata Ivleva)

Even in mSATA's heyday, though, a replacement was in the works. During development, it was known as NGFF, for "Next-Generation Form Factor." As it took shape, though, it took on its current, final name: M.2. The drives would be smaller, potentially more capacious, and, most important, not necessarily reliant on SATA. We actually like these because often, you often get a robust heat sink on the M.2 drive. Some PCI Express-bus M.2 SSDs can run hot under sustained read/write tasks and throttle their speed. That said, unless you're running a server or something similar, where a drive is constantly getting hammered with reads and writes, that's usually not something you have to worry about. That's because many of these drives are so fast, they get their transfer duties done before they have a chance to get all that hot. M.2 drive length isn't always an indicator of drive capacity, but therearelimits to NAND-chip density and how many memory modules engineers can stuff onto a PCB of a given size. As a result, most of the M.2 drives we've seen to date have topped out at 2TB, though you can find a few 4TB and 8TB models at lofty prices. The typical capacity waypoints are as follows: The earliest versions of M.2 PCI Express SSDs made use of the PCI Express Gen 2.0 x2 interface, which defines a throughput ceiling that's higher than SATA 3.0's, but not enormously so. That evolved into PCI Express Gen 3.0 x2 and x4, paired with a technology called Non-Volatile Memory Express (NVMe) to propel performance even further, especially with heavy, deeply queued workloads. 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.Performances (un de mes SSD WD a des performances moindres alors qu’il est situé au même endroit que son « jumeau »)

PlayStation 5 Compatibility: Designed to work seamlessly with PlayStation 5, the SN850X NVMe SSD provides an excellent storage upgrade option for gaming enthusiasts. It allows for faster load times and smoother gameplay on compatible gaming consoles. With better heat management comes better stability during peak performance. The slim M.2 combined with a low profile, graphene aluminium heat spreader is optimised for intense usage in gaming laptops and desktops. The optional heatsink model delivers an additional layer of thermal dispersion so when the game heats up, your PS5™ console stays cool. Kingston FURY Renegade SSD matches the top-tier performance of the Kingston FURY Renegade memory line to produce the ultimate team that will keep you at the top of your game.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. Of course, to show off the lighting, you will need to have an open-frame rig, or one with a see-through case. If you've already RGB'd your keyboard, mouse, video card, motherboard, case, and headphones, and are at a loss for what's left, the Spectrix S40G makes enough sense both in performance and looks to belong in any lighting-obsessed custom PC builder's arsenal. 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

I uninstalled some of my games (e.g. Baldur's Gate 3 & a couple of others) from my 6-y/o M.2 SSD & reinstalled them on this new SSD, the speed increase (especially shortened load times) was very noticeable. However, there are 2 issues that worsened the user experience for me: 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.

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 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. One last caveat to drop in before we get to our product recommendations surrounds Intel's SSD line. Intel for a while sold a family of M.2-based storage products under the brand name Optane, in two very distinct types of drive. Intel's"Optane SSDs"were SSDs like any other, bootable drives that can serve as a stand-alone boot drive or as secondary storage. They were discontinued for consumers in 2021, but you may still see them around. (Intel sold its SSD business at the end of 2021 to SK Hynix, which spun it off into a new subsidiary, Solidigm.)
