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

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.

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.
I am surprised there was no mention or inclusion of a single Sabrent-branded SSDs. I’ve been using a couple 2TBs for well over a year and no problems. I have an unopened 2TB NVMe v4.0 ready to deploy when I get my Lenovo X1 Extreme Gen 4. You might want to check them out. Here’s one link to a Black Friday special at Amazon.

Hi Dong,
My daughter has a ThinkPad X1 Carbon laptop. About a year ago, I upgraded its SSD from Intel Pro 6000p 256GB (SSDPEKKF256G7) to Samsung 970 EVO Plus 1TB (MZ-V7S1T0B/AM).
We found out that the 970 EVO Plus runs quite a bit hotter than the Intel Pro 6000p.
I think it might be useful to your readers, if you could include some temperature measurements, especially in ultra-portable laptops.
Thank you and Happy Thanksgiving!
When you need larger capacity drives, there is no competition for old mechanical hard drives. I would rather pay $200 for a 10TB mechanical drive than $1000+ for a SSD. Put 8 of them into a Synology DS1819+ and you really have a lot of $ put out in drives.
That’s true, Steve. These mostly are for the boot drive of a computer. You can use SSDs with a NAS though, you’ll be amazed how much faster your system is especially when you want to run VMs. More in this review of the DS1621+.
I know. I have an Alienware m17 r3 with 2x 2tb m.2 NVMe SSDs, and 1x 512GB m.2 NVMe SSD. On the 1819+. I have 8x 10tb HD (shucked WD EasyShares) and 2 Seagate Iron Wolf drives for caching
I’m impressed, Steve! On the shucked ones! It takes guts. 🙂
Not really. They are white label HGST drives. Most of the Seagate 10TB or larger are now IronWolf drives now. You have access to my email so if you want to email me, feel free.
Noted, Steve. Thanks. 🙂
Maybe this is insensitive (or plain ole back woods ignorance), but are spindle/platter drives still common in everyday computing? I purchase computers semi-regularly (I work in IT) and don’t think you can configure devices with anything but SSD for the primary (the Dell models we buy anyway).
I can’t even begin to fathom how long it must take for Windows 10 to do anything on a 7200RPM (or even 5400RPM, ouch!) drive.
There are still a lot of new (cheap) computers that use HDD on the inside, Lance. Not to mention existing old computers. But SSDs are taking over for sure. And you can also upgrade to a larger one.
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.
Please include WD SN850 NVMe Gen 4.0 drives as it narrowly beats Samsung 980 Pro while being little cheaper. It is also NVMe 1.4.
Noted, D. I’ll see to it. 🙂
