Step up to a $400 ceiling and the storage conversation changes: this is the budget where 2TB capacity comes within reach and where your first taste of NVMe speed becomes affordable. Where a sub-$300 budget keeps you in mainstream SATA, $400 lets you choose a roomy 2TB portable, a 1TB internal drive with headroom to spare, or a fast M.2 NVMe boot drive paired with bulk SATA storage. The defining question here is what tier you step up to: more capacity, more speed, or a smart mix of both. This guide rounds up the best SSDs under $400 in 2026 to help you spend that extra headroom well.
Our picks were chosen on what the $400 tier genuinely unlocks: the jump to 2TB, the option of NVMe alongside SATA, and the best balance of capacity, speed and reliability for the money. We have included a spread from a value 1TB SATA drive to a 2TB portable and an entry NVMe drive, because at this price the best SSD depends on whether you prioritise space, speed or flexibility. Below is an at-a-glance comparison of all six drives, then a closer look at each and a buyer’s guide built around reaching 2TB, blending SATA and NVMe, and choosing the right tier for your $400.

The SanDisk 2TB Extreme Portable is the pick that defines what a $400 budget unlocks: a full 2TB of fast, rugged storage you can carry anywhere, for around $294. It is an external USB-C (USB 3.2) drive rated up to 1050MB/s, doubling the capacity of the 1TB portable for buyers who have outgrown smaller drives. At this price it leaves a little budget to spare while delivering serious portable space.
This is the drive to lead with when your need is large-capacity mobility — a creator offloading 4K footage on location, a gamer carrying a sizeable library between machines, or anyone backing up a laptop with room to grow. The USB-C interface makes it far quicker than a portable hard drive, the rugged shell handles travel, and 2TB is genuinely generous. Remember it is an external drive that complements rather than replaces an internal boot disk. For hitting 2TB on the go under $400, it is the standout.
Pros: Generous 2TB portable capacity, fast USB-C speeds, rugged build, ideal for large mobile libraries.
Cons: External drive, not a boot disk; needs USB-C to reach full speed.

The Samsung 970 EVO Plus 250GB is your gateway to NVMe at this budget — the first drive on the list that leaves the SATA interface behind for the far faster PCIe NVMe M.2 form factor. At around $190 it brings Samsung’s acclaimed V-NAND and 970 EVO Plus controller to a compact 250GB M.2 drive, delivering read and write speeds several times higher than any SATA SSD here.
This is the drive to choose when speed is the priority and you want a fast NVMe boot drive, with bulk storage handled by a larger SATA disk. As an M.2 drive it slots directly into a motherboard M.2 socket with no cables, the 970 EVO Plus is one of the most respected NVMe lines for responsiveness, and 250GB is enough for Windows and your most-used applications.

The Samsung 860 EVO 500GB is the trusted SATA system-drive pick within this budget. Built on Samsung’s mature V-NAND with a refined controller, it is one of the most reliable 2.5-inch SATA drives ever produced, with a long record of consistent performance. At around $117 it commands a small premium that many buyers happily pay for Samsung’s pedigree and software support.

Rounding out the list is the Kingston A400 480GB, the cheap secondary-drive pick at this budget. At around $115 it is a no-frills 2.5-inch SATA drive that shines as an affordable add-on — extra storage for a build that already has a main drive, or a simple, reliable replacement for a mechanical hard disk in an older machine. It is the entry-level option here and is priced accordingly.
This is the drive to choose when you have spent the bulk of your $400 on a fast or roomy primary SSD and want inexpensive additional space, or when you are reviving an older system on a budget. Dropping the A400 in transforms an aging machine’s responsiveness, the 480GB capacity is a sensible amount for secondary use, and the SATA interface guarantees compatibility. It is not the fastest drive here, but as an affordable, dependable secondary or HDD-replacement drive under $400, the A400 does its job well.
Pros: Affordable secondary storage, simple SATA drop-in, reliable Kingston value, great HDD replacement.
Cons: Entry-level performance; smaller capacity than the 1TB and 2TB picks.
How to Choose an SSD Under $400
The $400 ceiling is the point where you should decide what to step up to, because this budget unlocks options a sub-$300 spend cannot reach. The two biggest are capacity and speed: you can now afford a full 2TB portable like the SanDisk Extreme, or your first NVMe drive in the 970 EVO Plus. Start by asking whether your current pain point is running out of space or waiting on slow loads, and let that decide whether your extra budget buys gigabytes or speed.
If capacity is the goal, $400 makes 2TB realistic. The 2TB SanDisk Extreme Portable is the headline option for mobile storage, while internally the MX500 1TB and BX500 1TB deliver roomy, reliable terabytes at SATA prices. Be clear about internal versus portable: the Extreme is an external USB-C drive that complements a system disk, whereas the SATA drives install inside your machine. Match the form factor to whether you need storage you carry or storage that lives in the case.
If speed is the goal, this is where NVMe enters the picture. The Samsung 970 EVO Plus is an M.2 NVMe drive that is several times faster than any SATA SSD here, but it slots into a motherboard M.2 socket rather than a SATA bay, so confirm your board has a free M.2 slot before buying. Because the 970 EVO Plus here is 250GB, the smart play under $400 is to mix tiers — a fast NVMe boot drive paired with a roomy SATA drive like the BX500 1TB for bulk storage gives you both speed and space within budget.
Finally, weigh reliability and the right tier for your needs. Trusted lines like the MX500 and Samsung 860 EVO add endurance and pedigree if longevity matters, while the BX500 and A400 keep costs down for bulk and secondary roles. Decide whether your $400 is best spent on one large drive, one fast drive, or a complementary pair, confirm the interfaces fit your machine, and pick the combination on this list that matches how you actually use storage. The right $400 build is the one tiered to your real workload.
Frequently Asked Questions
What does a $400 budget get me that $300 does not?
Headroom for either real capacity or real speed. At $400 a full 2TB portable like the SanDisk Extreme becomes affordable, and so does your first NVMe drive in the Samsung 970 EVO Plus — neither of which fits comfortably under $300. Whether you spend the extra on gigabytes or on NVMe speed depends on whether your bottleneck is running out of space or waiting on slow drives.
Should I get a 2TB drive or a faster NVMe drive at this budget?
It depends on your bottleneck. If you constantly run out of room, the 2TB SanDisk Extreme Portable or a roomy internal drive solves that directly. If loads and boots feel slow, the NVMe Samsung 970 EVO Plus is several times faster than SATA. Many builders under $400 do both — a small fast NVMe boot drive plus a large SATA drive for bulk — to get speed and space together.
Do I need an M.2 slot to use the Samsung 970 EVO Plus?
Yes. The 970 EVO Plus is an NVMe drive in the M.2 form factor, so it plugs into a motherboard M.2 socket rather than a SATA port. Check that your motherboard or laptop has a free M.2 slot before buying. If it does not, a SATA drive like the MX500 1TB is the better fit and still gives you a roomy, reliable upgrade within this budget.
Can I mix a SATA drive and an NVMe drive in the same PC?
Absolutely, and under $400 it is often the smartest move. Use a fast NVMe drive such as the 970 EVO Plus as your boot and applications disk for responsiveness, and add a large SATA drive like the BX500 1TB or MX500 1TB for games and files. Most desktops have both M.2 sockets and SATA bays, so this tiered approach combines speed and capacity within the budget.
