Best answer: The best setup for most is a combination, where the solid-state drive (SSD) boots Windows and most used applications, and the hard disk drive (HDD) is used primarily for mass storage.
What’s the difference between the two?
In its simplest form, an SSD is flash storage and has no moving parts whatsoever. As a result, they’re smaller and take up less space in a PC case, in some instances even mounting directly to the motherboard. SSD storage is much faster than its HDD equivalent.
HDD storage is made up of magnetic tape and has mechanical parts inside. They’re larger than SSDs and much slower to read and write.
Why use an SSD?
The beauty of an SSD is that this waiting time is dramatically reduced, even on cheaper drives, when compared to HDD. Anything you load on it will perform actions much quicker.
One of the best uses for an SSD in a PC is as a boot drive. This means installing a small-ish capacity drive on which your Windows 10 operating system will live and boot up from every day. By doing this, your PC will boot up and be ready to go in a flash. You can also put your most frequently used software on there for a similar effect.
SSD prices have come down a lot in recent times, too, with the price per gigabyte much lower than it once was. Large capacity drives are still expensive, as are the highest performing ones, but generally speaking, they’re more affordable than ever.
A note on PCIe 4.0 SSDs
If you’re using the AMD platform you might be able to use the new-gen, absurdly fast PCIe 4.0 SSDs. These are currently the fastest consumer drives on sale.
However, unless you’re using both a Ryzen 3000 processor and the AMD X570 chipset on your motherboard, you won’t be able to take full advantage.
Take full advantage of the new, fast PCIe 4.0 SSD with the Sabrent Rocket and get up to 5,000 MB/s read speeds and 2,500 MB/s write speeds.
If you are, something like a Sabrent Rocket is both great value and incredibly fast.
Why use an HDD?
PC cases usually have space for more than one drive, meaning you can stack up as much mass storage as you can stash and your budget will allow.
Price per gigabyte is still much less than SSDs, and large capacity drives won’t take all your money. An efficient system would have an SSD to boot Windows from and one or more HDDs for mass storage.
If you can have an NVMe drive in your PC, then these will yield the best performance, and thankfully aren’t that expensive anymore. Our ultimate recommendation is the Samsung 970 EVO Plus thanks to its reliability, insane performance, great warranty, and reasonable price.
The best SSD money can buy.
If you’re building a PC in 2019, there’s a strong chance you have support for NVMe drives on your motherboard, and this is the best of the bunch. Insane read and write speeds meet proven reliability, user-friendly companion software, and a stellar warranty.
If you’re looking to get some of that NVMe performance on a budget, you can also do that with the excellent Sabrent Rocket. It’s not as fast as a Samsung SSD, but it costs a good chunk less.
Best budget NVMe
Excellent performance at a low price
While write speeds aren’t the greatest you’ll find, on balance, this is an excellent SSD, especially at the price, and a definite upgrade from an HDD or a SATA SSD.
For mass storage, whether you go for a 2.5-inch SSD or an HDD, these are our top recommendations. Both are from well-respected brands, are reliable products and won’t run away with your wallet.
Best 2.5-inch SSD
Samsung quality, lower price
If you’re looking for a great 2.5-inch SSD for a laptop or desktop, this is it. You get great performance, a great warranty, and an affordable price. Great for all-purpose use.
Store all of the things
This is a great HDD available in some quite massive storage sizes, which makes it perfect to store large quantities of files, less important apps, and games.
|Attribute||SSD (Solid State Drive)||HDD (Hard Disk Drive)|
|Power Draw / Battery Life||Less power draw, averages 2 – 3 watts, resulting in 30+ minute battery boost||More power draw, averages 6 – 7 watts and therefore uses more battery|
|Cost||Expensive, roughly $0.20 per gigabyte (based on buying a 1TB drive)||Only around $0.03 per gigabyte, very cheap (buying a 4TB model)|
|Capacity||Typically not larger than 1TB for notebook size drives; 4TB max for desktops||Typically around 500GB and 2TB maximum for notebook size drives; 10TB max for desktops|
|Operating System Boot Time||Around 10-13 seconds average bootup time||Around 30-40 seconds average bootup time|
|Noise||There are no moving parts and as such no sound||Audible clicks and spinning can be heard|
|Vibration||No vibration as there are no moving parts||The spinning of the platters can sometimes result in vibration|
|Heat Produced||Lower power draw and no moving parts so little heat is produced||HDD doesn’t produce much heat, but it will have a measurable amount more heat than an SSD due to moving parts and higher power draw|
|Failure Rate||Mean time between failure rate of 2.0 million hours||Mean time between failure rate of 1.5 million hours|
|File Copy / Write Speed||Generally above 200 MB/s and up to 550 MB/s for cutting edge drives||The range can be anywhere from 50 – 120MB / s|
|Encryption||Full Disk Encryption (FDE) Supported on some models||Full Disk Encryption (FDE) Supported on some models|
|File Opening Speed||Up to 30% faster than HDD||Slower than SSD|
|Magnetism Affected?||An SSD is safe from any effects of magnetism||Magnets can erase data|
