Best SSD Hard Drive 2018Geekheads Team
Building a new rig, or looking to upgrade your existing machine’s storage, but don’t know which SSD to go for? Well, you’re in luck. We’ve tested all the big-name products on the market to offer the definitive list of the best SSDs currently available.
An SSD (solid-state drive) is the simplest and most cost-effective upgrade you can make to a laptop or desktop. Not only will it speed up your PC’s boot-up times, but opening applications and searching for files will be quicker too; in general, it will make your system feel far more snappy.
In the very simplest terms then, an SSD performs exactly the same function as your regular hard disk (or hard drive, if you prefer) but much, much faster. It replaces the mechanical aspects of your hard disk with non-moving transistors. Although more expensive than a hard disk, the performance benefit an SSD offers is absolutely worth the money.
SSD jargon explained
NAND Flash: Negative AND Logic gates. They’re similar to the chips used in RAM, but they can store data even when there’s no power flowing through them. They form the basis of all SSDs.
Controllers: SSDs, like other storage devices, are little computers in themselves. Controllers look after the algorithms that sort through data. The faster the controller, the better the performance.
SATA: Serial ATA. This is the most common, and cheapest type of SSD. It connects through your motherboard’s SATA ports and while it’s several times faster than a regular hard disk, it’s the slowest form of SSD, topping out at about 500-600MB/s. The current version of SATA is SATA III.
NVMe: Non-volatile Memory Express. This type of SSD connects over PCIe (PCI Express), with drives topping out at over 3000MB/s. You’ll either find it connecting directly to your motherboard’s PCIe slots or over M.2 (below), also using PCIe lanes.
M.2: This is a specific physical SSD format. Confusingly it can use both the SATA or PCIe lanes on your motherboard, but either way it fits into a smaller M.2 slot. M.2 SATA drives are most commonly found on ultra-thin laptops to save space (M.2 is very small) and cost (sometimes only using SATA-speed storage). If you’re buying an M.2 SSD for your desktop, make sure it’s an NVMe drive.
