Read the spec sheet carefully when you buy a sub-$500 laptop, because sometimes companies will tout a laptop with eMMC as having "solid state" or "Flash" storage.Įven though it has no moving parts, eMMC memory is often slower than a hard drive. While SSDs have powerful controller chips and fast NAND Flash memory, eMMC drives are made to be cheap and use similar components to an SD card or USB stick. Some of the cheapest laptops on the market (think under $300) come with a form of solid-state storage called eMMC (Embedded MultiMedia Card) memory, usually in 32 or 64GB capacities. What about eMMC storage (aka eMMC memory)? The Dell XPS 13 base model comes with a 128GB SATA SSD, and the company charges $100 to move up to a 256GB PCIe SSD (there's no 256GB SATA option).īottom line: An NVMe-PCIe SSD is a nice-to-have if you can afford it. When buying a laptop, you usually don't get a choice between SATA and PCIe SSD configurations with the same capacity, though PCIe drives do cost more and come in more expensive laptops. As a consumer, your best bet is to check benchmark reviews like ours to see how the drive in your potential laptop performed. For example, the ThinkPad Yoga 370 that we tested had a 256GB Toshiba PCIe SSD that managed only 145.7 MBps on our test, less than most SATA-based systems. Unfortunately, not all PCIe-NVMe SSDs are created equal. Some high-end gaming systems have dual PCIe-NVMe SSDs that work together in what's called a RAID array, and those can get rates of over 1,000 MBps on our test. Where a typical SATA SSD might return a rate of 150 to 175 MBps on the LAPTOP File Transfer Test, which involves reading and writing 4.97GB of files at the same time, a normal PCIe-NVMe SSD will get between 250 and 500 MBps. The fastest PCIe-NVMe SSDs on the market can theoretically read and write at four or five times the speed of a SATA unit, but most PCIe-NVMe drives we test are 1.5 to three times quicker than an equivalent SATA drive. However, some more expensive laptops use drives based on the PCIe-NVMe standard, which is sometimes listed as just NVMe or PCIe but is the same thing. Typical mainstream hard drives use the same SATA (aka SATA 3) interface as mechanical hard drives, but that connection is limited to about 550 megabytes per second, which is still four or five times more bandwidth than a hard drive uses. Most consumer and business notebooks don't have room for multiple storage drives, but 1TB external USB hard drives cost under $60.īottom line: Get at least a 256GB SSD, or 512GB if you do more storage-heavy work. ![]() Some gaming laptops solve this expensive dilemma by coming with both an SSD for key applications and a hard drive for data. ![]()
