At one point, SSDs were a fairly niche market. However, the prices of SSDs have dropped considerably over the past few years. Today, an SSD is a must in any system, and even the cheapest SSDs are multiple times faster than a hard disk drive. Whether you’re building a desktop or buying a laptop, you’ll want it to have an SSD. To help you make an informed buying decision, we have created a guide containing the 20 best cheap SSDs.

Top 20 Cheap Solid State Drives (categorized by capacity):

SATA vs M.2 SSD – what’s the difference?

Modern SSDs are extremely fast. They’re so fast, in fact, that the limiting factor is more often the SATA connection that has been around forever, for both hard drives and solid-state drives. To avoid this limit, modern SSDs often come in an M.2 form factor.

Form Factor

The form factor is the most obvious difference. A SATA SSD on the outside looks just like a 2.5” hard drive. However, an M.2 drive is much smaller and lighter, taking up much less space. This is why M.2 drives are often preferred in slim and light laptops, such as ultrabooks.

Speed

Next, we have the speed. One thing to note, though, is that there are still SSDs in the M.2 form factor that works at SATA speeds. If you want a speed advantage, you should be looking at NVMe drives, such as Samsung’s much appraised 970 Pro lineup. NVMe SSDs are much faster than SATA SSDs.

Reliability

Reliability is more or less identical. None of the drives have any moving parts, and cooling either of them depends on your specific PC or laptop. If you’re only considering going one way or the other due to reliability, you really can’t go wrong with either.

Price

Last but not least, we have the price. M.2 drives, especially the NVMe ones, are usually a bit more expensive than their SATA counterparts. You are basically paying for a higher speed, and this is oftentimes worth it. However, the difference you’ll be getting in terms of price and performance is more than worth it. You can learn more about the differences between M.2 and SATA SSds here.

Should you get a SATA drive or an M.2 one?

If you can afford it, we would recommend that you always go for an M.2 NVMe SSD as they’re much faster than SATA SSDs. There’s one small thing to note, however. Since M.2 is still a fairly new standard, you’ll want to check whether your PC’s or Laptop’s motherboard has an M.2 slot. If it does, you’re better off with an M.2 drive.

However, you’ll also want to check if your motherboard has enough lanes to take advantage of NVMe speeds. If it does not, just get an M.2 or 2.5-inch SATA drive depending on your preference and budget.
