Samsung 840 EVO SSD SATA III Benchmarks & Review

Samsung 840 EVO SSD 500gb SATA III, – I got one a little while back, and I’ve been using it for just about one year now.

That being said, let’s get the benchmarks for the Samsung 840 EVO SSD out of the way.

Samsung 840 EVO SSD Performance Tests on a SATA II System

When I first got this drive I was using an older computer that capped out at SATA II speeds. However, this SSD is capable of SATA III speeds. So bear that in mind, especially when you’re watching the video above.

For a comparison, here are the benchmarks from my old drive a, Seagate Moments XT 7200rpm 4gb SSD hybrid drive.

When I first ran the benchmarks for the Samsung 840 EVO SSD, just after having installed it, here’s what I got out of the box. Keep in mind this is on an older system that capped out at SATA II. YOUR PERFORMANCE WILL PROBABLY BE BETTER.

Naturally I was disappointed at first, I thought I’d get 500mb read speeds right away. However, as it turns out my initial disappointment was quite premature as all I needed to do was a little bit of configuring.

Now, mind you, because my old computer capped out at SATA II, the fastest I got was this;

Configuration with Samsung Magician

To get maximum performance from the drive, just head over to Samsung’s website for the 840EVO here.

They’ve got links to a few different software applications but to keep things simple for yourself, just download the Samsung Magician software and it’ll take care of the rest for you (such as settings, firmware updates …etc.).

Run the Magician and let it guide you, it’s pretty friendly, & it’ll even tell you if your software or your SSD firmware is out of date.

Then you can choose a couple of presets or you can customize the settings yourself. There are presets which lean towards longevity and stability and presets which lean towards maximum performance. I lean more towards longevity myself.

Then there’s an option to enable RAPID mode (seen in the image above, to the right, under ‘Advanced Feature’), and this is what I used to attain the amazingly fast 500MB seq read/write speeds as advertised by Samsung.

 

Testing the Samsung 840 EVO SSD on a SATA III System

But thankfully I no longer have that old Acer Aspire 8930G, though it was a good laptop. Now I have a Sager NP9377, and Sager is uh may zing!

So with a computer capable of SATA III speeds… here is what you get without RAPID mode enabled.

Even without RAPID mode, most my heavier programs load in just a few seconds.

When I first enabled rapid mode… I almost couldn’t believe it. I thought crystal disk was messin’ with me.

I should note I actually did two things here, first was change the preset under ‘OS Optimization’ to ‘Maximum Performance’ and the second was to enable RAID, which requires you to reboot your system. Also, I noticed doing this take up a little bit of space on the drive, as you can see by comparing the last two benchmarks.

In this mode Windows takes about 30 seconds to boot up to the desktop from a cold boot, and shutting down takes about 14 1/2 seconds.

Of course this has also done some wonders for my gaming frame rates. I won’t get too technical about it but it should go without saying that if the storage drive is the biggest bottleneck in a computer system, then speeding it up should make everything else go faster (or rather optimize the performance you get out of the system as a whole). Basically your computer is only as fast as your storage drive, and if your storage drive can’t handle the speed of the rest of your components, it’s gonna bring you down. Speeding up your storage doesn’t necessarily make your GPU or your CPU faster, it just allows you to experience the fully optimum speed that was already there to begin with, but now you CPU & GPU & memory or unencumbered by a slow storage device.

In short, it was awesome without RAID, and with RAID it’s like.. wow. Are there faster drives out there? I’m sure of it. But unless your a computer scientist running some super simulation calculation, I doubt anything faster is going to be very noticeable. I suppose if you need more space or if every ounce of power matters then you can go for the Samsung 840 EVO SSD PRO version.

 

What others are saying

User RetiredChief says,

840 EVO uses 19nm TLC, 840 Pro use MLC and has a higher write cycles rating

User OUT FOX EM says,

Speaking of RAID 0, if you’ll notice, all the drives of 250GB and higher perform around the same. You are MUCH better off getting 4x250GB drives instead of the 1TB.

I recommend you read the rest of the comments on these sites, there’s a lot of great information in there.

Caveats & Cautions

Before you do something too rash, allow me take a moment to warn you about SSD’s. Yes, they are fast, and yes they boost performance tremendously. Many of the high priced ones will last you a long time too, perhaps even 1 or 2 years. Be warned, though, that because we’re dealing with flash memory, when they go; they just go. A mechanical hard drive dies slowly, but an SSD, just dies. It’ll perform outstandingly right up until the moment it turns into a pumpkin at midnight. So if you are going to use an SSD for all your files, at least have an automatic backup running in the background that keeps your data mirrored onto a mechanical drive.

I suppose you could use an online cloud service like Carbonite, or something similar, but I prefer the old tried and true method of just buying a mechanical drive plugging it in through the USB and having some software sync the files in the background. It’s easy and of course you don’t need to worry about someone hacking into your encrypted backup because it’s not over the web.

For a backup drive that’s easy to use and syncs everything for you, have a look at this, Seagate Backup Plus Slim 1TB.

Conclusion

Alright, lastly, do I think the drive is a buy, or not. Well, I’m happy with it so far. The performance has been good. I’ve never used an SSD as my main driver before so, I’m a little nervous about things like, ‘will I get a warning before it goes out?‘, and ‘how long will it last?‘ however it’s lasted me just fine this past year, I usually leave the RAPID mode off just to make it last longer and without

that enabled I still get decent performance. Not to mention I keep all my files backed up. Very important!

I’ve never had an issue with file corruption, nor have I had any problems with moving files, large or small, to or from the drive. Regardless of operating system (I’ve run a couple virtual Linux OS’s for when I’m doing web development).

So for me, yes, it’s a buy.
