Migrating your computer from a hard drive to a solid-state drive (SSD) is by far the most gratifying upgrade. So, getting the right drive is naturally an important task. This post includes the best SSDs I’ve reviewed.

Best SSDs of 2021: The lists
You’ll find here standard SATA and NVMe drives, divided into two lists in reviewed order with the latest on top.
NVMe and SATA are two different internal storage types — more about them in this post on SSD basics.
Best NVMe SSDs of 2021: A must for a top performing computer
Newer and much faster NVMe SSDs require a host that has an M.2 slot. Most computers released in the past five years have this slot built-in, but you can upgrade to one on almost all desktop computers via a PCIe adapter.
7. SK hynix Gold P31: Arguably the PCIe 3.0 NVMe drive of the best value
The Gold P31 is SK hynix’s first retail NVMe SSD and it proved that the out-going PCIe 3.0 standard still has a lot to offer. The new drive delivered a stellar performance in my testing and even edged out the PCIe 4.0-based drive below in certain tests.
That plus the higher endurance and much more affordable pricing mean this is an excellent NVMe deal, if not the best to date.
SK hynix Gold P31 PCIe NVMe Gen 3 M.2 SSD
$134.99

Best SATA SSD of 2021: An easy upgrade
The SATA standard is much slower than the NVMe above but still significantly faster than any traditional hard drive.
A SATA SSD will fit in the place of any regular hard drive and therefore, will make an easy and satisfying upgrade in any computer that still runs on a hard drive.

Best SSDs of 2021: SATA vs. NVMe performance
When reviewing solid-state drives, I generally only stack drives of the same type (SATA or MVMe) against one another. Since this list includes both types, however, you’ll find below performance charts of all drives. So, you’ll see here how SATA drives stack up against NVMe counterparts.
Sequential (copy) performance
This chart shows how fast solid-state drives perform when copying a large amount of data from one place to another. It applies general data transferring tasks, such as when you want to backup your data or, recovering data from a backup
Random access performance
Random access performance shows how a solid-state drive affects the host computer’s overall performance. It represents tasks like launching an application or editing a large data file.
Now that you have found out which drive you should get. Check out how you can migrate a hard drive to an SSD or do an MVMe upgrade on your Windows 10 machine.
consider ADATA XPG SX8100 512GB 3D NAND NVMe Gen3x4 PCIe M.2 2280 Solid State Drive R/W 3500/3000MB/s SSD (ASX8100NP-512GT-C)
I’ll check it out, Ron. Thanks for your suggestion.
Why no SanDisk SSD? Great budget SSD and good performance options. I have two 960GB Ultra IIs that are going strong 4-5 years now.
They haven’t made new ones for a long time, WP. The one you mentioned I reviewed in my past life at CNET, not on this site.
