SABRENT M.2 NVMe SSD 8TB, Internal Solid State 3300 MB/s Read, PCIe 3.0 2280, M2 Hard Drive High Performance Compatible with PCs, NUCs Laptops, and Desktops (SB-RKTQ-8TB)

Product Information

This flash is more or less equivalent to 128-layer TLC from other manufacturers, such as that found on the 980 Pro by Samsung or on the Gold P31 by SK hynix. BiCS5 should come with a bit lower latency than the old 96-layer BiCS4 flash that’s been used in many products and often as an alternative to Micron’s 96-layer B27B TLC. We’ve seen good results from it on the SN570 and, especially, the SN770. 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. 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.

PCI Express: The Modern Speed Standard

Right now, the five main processes in 3D NAND are 32-layer, 64-layer, 96-layer, 128-layer, and 176-layer. More layers don't necessarily bring a performance bonus, but generally bring a lower price for drives of the same capacity. For a desktop, the right SSD to buy depends much more on what you are doing with your computer, and what your aim is. If you're building a new PC from scratch, you definitely want an internal M.2 or 2.5-inch SATA SSD as your boot drive nowadays. A 2.5-inch SATA drive might make sense only if you're upgrading or building from older hardware, because almost all new motherboards now have at least one M.2 slot of some kind, and these drives save lots of space in compact PC builds. Finally, the price of an SSD can also be affected by the memory element "method" used to store data. The four different types are single-level cell (SLC), multi-level cell (MLC), triple-level cell (TLC), and quad-level cell (QLC), respectively storing one to four bits per cell. SLC is both the fastest and most durable of the four types, but it's also the most expensive and rarely seen outside enterprise drives or as a chunk of cache used alongside one of the other technologies. MLC is less durable and a bit slower, but more reasonably priced, while TLC and QLC have pretty much taken over the mainstream; they are the least "durable" but also the cheapest. (More on drive endurance in a moment.) That said, with games in popular series like Call of Duty requiring over 100GB of space just for one title, the drive could end up full again faster than you can line up a sniper shot. These days, if you're looking to get just one roomy drive (or maybe you have to, such as for a laptop), 2TB is the recommended size for gamers, while hardcore content creators who are dealing with 8K RAW footage will need far, far more. (A one-hour 8K RAW file will occupy 7.92 terabytes of space.) (Credit: Molly Flores) 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.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.

Going with anything less than 4TB with the 870 QVO will turn out to be a bad value as even TLC-based SATA SSDs without a powerful controller and DRAM cache will perform better in durability and transfer speeds. The main reason for QLC is that it makes 8TB a possibility and reduces the price-per-GB significantly to make it a worthwhile consideration. That said, while almost any SSD is much faster than any hard drive, not all SSDs are created equal—not by a long shot. SSD interfaces have evolved greatly over the last few years, and SSDs themselves are taking on different shapes and core technologies.The 870 QVO’s write speed comes in at 530MB/s, while the read speed is set at a slightly higher 560MB/s. The write endurance of the SSD is rated at 2,880 TB, much higher than the QLC NVMe SSDs we saw earlier. The high capacity of the 870 QVO and its 2.5-inch form factor makes it the ideal choice for replacing your existing high-capacity hard drives, as the performance gains will be pretty significant than even the fastest ones. The maximum sequential read speed that's theoretically possible for a SATA drive is 600MBps, though as we said above, we haven't seen any drives reach that limit even in ideal testing conditions. The theoretical peak sequential read speed for PCI Express 3.0 x4 drives is much faster—3,940MBps, although the fastest one we've tested in-house is the Samsung SSD 870 EVO, which topped out at 3,372MBps read speed in the Crystal DiskMark 6 benchmark. 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. The SATA interface is capable of sequentially reading and writing a theoretical maximum of 600MBps in an ideal scenario, minus a bit for overhead processes. Most of our testing has shown that the average SATA drive tops out at roughly 500MBps to 550MBps; in sequential tasks, the real-world difference between the best SATA drive and a merely average one is pretty small. Storing a larger amount of bits per cell is great for increasing SSD capacity but significantly reduces the drive’s endurance and write performance due to the larger amount of data being written per cell. To counter this, manufacturers will allocate a fraction (typically 1/4th) of the SSD to function as an SLC flash-based cache. However, on reaching the end of the SSDs limit, the cache is significantly reduced to free up space degrading the performance. NVMe Is Faster than SATA

Solid-state drives come in all shapes and sizes and are built for almost every purpose. Whether you need a drive whose first priority is dollar-savings, or one that will load up a 4K movie in less than half a second, there's an SSD made for the job.Controllers are a factor of SSD buying that only ultra-geeks will care about, but they're still important. The controller is a module on the SSD that essentially acts as the processor and traffic cop for the drive, translating the firmware instructions into features like error code correction (ECC) and SMART diagnostic tools, as well as modulating how well the SSD performs in general. (Credit: Zlata Ivleva) PCI Express 5.0 is the latest and by far the fastest. It offers substantial throughput increases, with maximum read and write speeds of up to 14,000MBps, effectively double those of the fastest PCIe 4.0 drives. Only the latest high-end desktops support this bus off the shelf, so you may have to build your own PC from scratch or perform a motherboard and CPU transplant on an existing desktop. Intel users will need a 12th or 13th Generation Core CPU with a motherboard based on Intel's Z690 or Z790 chipset. AMD fans must have a Ryzen 7000 series processor on an AM5 motherboard with an X670, X670E, or B650E chipset. Note: The board must specifically have a PCIe 5.0-capable M.2 slot, too; not every board with chipset-level support does! (Also know: Laptops can't leverage the peak speeds of these drives, yet.) Without getting too bogged down in the specifics, QLC is effectively 4-bit NAND. The original kind of NAND flash memory used in SSDs was single-level cell (SLC) which is able to hold one bit per cell. Multi-level cell (MLC) was then introduced to bump up density and lower pricing, offering two bits per cell. Then came triple-level cell and now quad-level cell, and there is even the spectre of penta-level cell on the horizon too. Before we jump into the list of the best drives we've tested recently, we should mention that although this is a roundup of the best internal SSDs, these days just about any such drive can be turned into an external USB unit with the help of an SSD enclosure. These are often little more than durable housings of plastic or metal, and you can buy enclosures for almost any type of SSD: SATA 2.5-inch, SATA M.2, or PCIe M.2. Just make sure that the enclosure supports the form factor and bus type of the drive you want to "externalize." Of course, you can also buy premade external SSDs; we've rounded up the best of them, as well.
