After 7 Years Still 90% Drive Life

Reviewed in the United States on April 8, 2021

Verified Purchase

I was just browsing through HWINFO and noticed that 1 of my drives had 87% life left and thought that didn't seem right so I went looking through my order history and realized I bought this in Dec 2014. Yikes. I thought I had only had it for a few years but wow does time fly. I went from being confused to happy finding out the integrity only went down 10% in almost 7 years. This was my boot drive the whole time I owned it and it worked great. Over the last few months I did notice the drive has slowed down a little bit (power on times increased maybe 3-5 seconds) but nothing huge. I don't know if I would recommend this today since there are a lot of really good options at good prices but if you can find one cheap it's a great option. If you get the 250GB version I wouldn't recommend this as your only drive if you game at all. By the time you install Windows and Steam and a few games it's full. As a boot drive it's perfect size.

Consider me a believer of this technology

Reviewed in the United States on September 24, 2014

Verified Purchase

I finally believe - after years of holding off, I purchased a SSD and have never been happier.

My first hard drive was a 20MB (that's Mega, not Giga) that cost me around $400. It was years ago and one of the "fastest" models on the street at the time. I was stoked, as it could hold tons of my old floppy (perhaps you've never seen one, so Google what they look like) disks and kept me from having to switch disks every few minutes to play a game or run a program.

As hard drives grew in size, so did software, leading to a never-ending race between manufacturers and software developers. Thankfully, the drives kept up and constantly tweaked platter capacity and spindle speed to get more power, use, and efficiency from this technology. But that's the sticking point - old hard drives required rotating disks, that needed to be "read" in order to load a program. So, no matter how fast or big they got - you still had lag time between sending the command and the actual software loading.

Solid-State Drives (SSDs) have alleviated most of this lag, because there are absolutely NO moving parts. None. The entire concept (in simple terms) is similar to the USB keys we've all grown accustomed to using. The drive is basically large memory capacity memory chips stuck inside a plastic case with an advanced controller (which is tweaked by the developers) to help direct the command from the computer to locate and execute the program/command you are sending. This all happens in near real time!

Imagine your computer loading in just a few seconds, instead of nearly a minute or longer. Imagine software that you use often, loading within a second of clicking it, instead of clicking and waiting as the computer sends the command, but then sits and waits for the hard drive to spin up and find the actual code, process the code and send it to the CPU for processing. Imagine not hearing the spinning sound of your hard drive any longer. Seriously - there are no moving parts to hear. This thin little drives consist of a board, memory chips, a controller, and a sprinkle of magic (okay, the last part may be just my special model...or not).

The one thing to remember about these drives is that they are smaller than regular 3.5" drives. They take up less room, but also require different connectors to fasten them to your machine. Make sure your machine can hold a drive like this or can be modified to hold a drive like this (you can also buy aftermarket brackets to assist). Some folks have left the drive just sitting in their machine (not connected/secured to anything) and while this may be okay if you never plan to move the computer, I am a bit hesitant to have something that can flop around inside my case and damage other parts. As an added bonus, these drives produce very little (read: not zero, but far less than old drives) heat. Since there are no moving parts - the only heat produced comes from the electricity running through the drive when under heavy use.

There is lots of talk about these drives having "limited" shelf life, because the memory can only be rewritten so often before it locks the bit. While that is true - memory like this can only be erased and written so often - but that number is far higher than any average user will ever see in their lifetime of using this drive. And when the bit does finally lock - it locks with the data that is currently on it - not "blank", which means you won't lose your data, you just won't be able to write new data to that block any longer. Not a big deal, again, unless you write/delete/rewrite tons of data to your drive on a daily basis for years on end. I've seen estimates from reputable review sites that estimate it would take the average user 5-10yrs to kill a data bit on these drives. By then, you'll likely upgrade or acquire a new machine anyway.

The one thing that annoys me is the cost of these little things per gigabyte. I know the memory isn't cheap and the technology is new, but you'd think that having no moving parts is cheaper than having expensive moving parts. The good thing is - prices are coming down. Also, these drives aren't huge. While they finally have 1TB drives and growing, you're still better off using an old hard drive that holds 2-3TB for data storage and use a drive like this for your operating system (Windows, Apple OS, or Linux) and software that you want to boost. My configuration has this 256GB drive running my OS and a 1TB drive for all my data (music, movies, games, etc). The benefit is that the software you are running is still enhanced by the speed of this drive and the data being pulled from the other drive is easy and fast enough that you won't notice any issues.

Overall, I'm a big fan of this technology and now consider myself a true believer of the SSD technology hype. While I have not owned this drive for longer periods yet - so cannot speak to reliability - I know that this drive has been tested by countless expert reviewers and none have found any issues to date. Samsung has an excellent software suite that enhances this drive even further and keeps it updated with the latest fixes they develop. You wont' go wrong buying a EVO series drive from Samsung - your only real decision is what size you need to meet your needs.

Mac A1342, White Unibody Performance Upgrade

Reviewed in the United States on March 31, 2014

Verified Purchase

I picked this up after seeing videos on how much speed this can add to just about any system. My macbook A1342 is the best computer I've owned but it is aging. Rather than go out and get a replacement, I started looking at upgrade options that I could perform myself (besides just ram of which I have 8GB currently.)
Using this SSD as my primary drive has brought this macbook to "better than new" status. It boots in about a fifth of the time it used to, programs load nearly instantaneously. Even brand new, this was not the case. I use the most recent photoshop (CS6) and I used to get stuck with that spinning color wheel for up to two minutes while it loaded. Not only do I no longer see the color wheel, I can start using CS6 almost immediately after it opens (which takes about 2 seconds.)
Here's what I did:
I installed my old HDD in a drive caddy and replaced my optical drive. At the same time, I installed the new SSD in the HDD's old tray.
I booted my mac from the old hdd and then used Carbon Copy to clone the HDD to the SDD. That part took about two hours.
I then changed the primary boot drive to the SSD in the macbook's settings and rebooted it.
DONE!
There are lots of vids on line on how to do this but there is one thing that I ran into that I didn't expect. The SSD seemed to be running very warm/hot. Make sure your reset the mac's SMC when you do the drive swap. It's simple and details can be found on Apple's website and eslewhere.
Bottom line: do this upgrade! I don't think I will ever go back to using a standard HDD at this point. I've been spoiled!

Amazing SSD

Reviewed in the United States on December 21, 2015

Verified Purchase

I get this on October-2014 at a price of USD$130, was really expensive back then but was my choice to give my computer a performance boost without major changes, my board is from 2011, so is pretty old, but to change it implies change a lot of parts to improve the traditional way.

So I make the effort and get this SSD to improve my PC, the outcome has been amazing, my PC boots faster than my phone, in less than a minute I have my session up with all the startup applications I need running from a cold start.

The downside for me was the small size, but I move as many applications from my main partition, so my documents, images and stuff like the temporals from my web browsers were moved the regular mechanic HDD.

There are lots of recommendations to improve the performance of the SSD by moving components and Microsoft Windows behavior, I took some of them in consideration and so far so good, have been running my main system for over 15 months without any complains.

The tools from Samsung to move the installation work with the system up and running so I didn't trust the outcome of the cloning, I use another tool Acronis True Image, that runs in a cold start making me believe the outcome will be more reliable, so far no need to get back to my old HDD not a single time.

So I'm really happy to see my machine working so smooth thanks to this upgrade of HDD to a SSD, now my other hardware from 2011 will continue to perform for a few more years.

Brilliant SSD - Fast and Reliable

Reviewed in the United Kingdom on April 23, 2018

Brilliant SSD, had mine for 2 years now and it still works as good as the first day i got it.

Samsung dominates the SSD market for the sheer quality and performance of it's SSD'S!

The Magician Software for the SSD's also keeps you updatd as to when your ssd shows any sign of issues or a decrease in performance.

It also allows you to run Disk Optimisation Software and Performance Trackers to check the Read/Write Speed of the SSD.

The Magician Software also easily allows you to shift existing Data from one SSD to the other, making an SSD upgrade super easy and simple.

Super Fast Drive with Excellent Reliability

Reviewed in the United Kingdom on September 9, 2016

Verified Purchase

I have been using this SSD drive for 2 years now both inside a Macbook Pro laptop and a Windows 10 desktop. It's one of the best drives I've used in terms of speed and reliability.

The SSD comes in a nice box with a software CD, although the software can be downloaded from the Samsung website. As long as the Samsung drive is connected to your computer you can use the software. In terms of hardware installation it was fairly easy and straight forward. It doesn't contain any mounting screws so you may need some when installing. Once the drive was installed a simple format and you're ready to go. This is one of the fastest drives on the market for SATA3 with speeds around 550MB/s Read and 500MB/s Write (I've included a speed test in photos). The software included is okay if a little limited. The Samsung Magician allows you to update the SSD firmware (please do this before moving files to the drive!) and check drive condition and speed. The Data Migration software allows you to migrate ONLY your Windows Boot Drive (C: Drive) to the Samsung SSD. So you can't clone another drive to the Samsung SSD, which is unfortunate.

I'm really happy with this drive; it works great for Adobe Applications and anytime you need fast Read/Write Access. Great performance and reliability from a brand I trust. I highly recommend this Samsung SSD drive.

Photo editing speed improvement.

Reviewed in the United Kingdom on February 25, 2015

Verified Purchase

Didn't use the Samsung migration software. Instead I installed SSD in desktop (using cheap adaptor tray), connected a SATA cable and power. Used the excellent (free) Macrium Reflect software to clone my existing O/S HDD to the SDD. The HDD partitions filled it's 1TB, but there was actually only 170GB of data on 5 partitions so I shrank the partitions down (easy with Macrium) so everything fitted on 240GB when it cloned . Booted into BIOS and changed the boot device to the SDD...and bingo it came up fine.
Imaged everything to USB backup drive then formatted the HDD which is now just for storage.
PC much quicker and noticeable improvement when editing big image files using Adobe Elements.
So far so good.

BUY IT!!!!

I have been looking at different ones for a while and then decided on the Samsung one because of the price & reviews (no prejudice)
I didn't like the new SanDisk Drives as they have had bad reviews for speeds
Anyway, after ordering the drive Sunday, it turned up Tuesday, Inside the box there was the usual manuals etc along with a software CD, this included 2 programs, 1 Samsung Drive cloning program. 2 Samsung Magician
No I'm not afraid of cloning drives and it's not the first time that I have done it with various programs.. The Samsung drive cloner was as simple as any other I have used and copied 88gb of data from my previous SSD in about 15 minutes

The real shock comes later... after rebooting the system with the new SSD in, it booted the same as my previous one (speed terms)
I opened the Magician program to do some disk transfer speed tests and i was very happy. the max read / write for this drive should be 540 Read & 520 Write
my first test was 537/408.. perfectly respectable

I then went into the settings and changed some things (inside the magician program)
1) OS Optimisation- Selected "maximum performance"
2) Over provisioning - selected the 10% recommended size
3) Rapid mode - Turned it on
after restarting twice everything was like super speed... the shutdown / reboot times were significantly shorter, full shutdown / reboot in about 20 seconds and start up from cold is roughly 10-15 seconds
the Real shock comes now.... I did more Data transfer speed tests and was astonished
2775 Read & 1815 Write....

this keeps on happening and i am getting similar speeds every since doing it. ( i am attaching screen shots of the speed tests )
In practical tests it will also let me move a 1.5gb movie file to and from another ssd in under 1 second

In conclusion... Buy the thing, you will be happy

I bought this item in 2014. It's still going strong.
It was used as my Operating System drive until recently. But I have since moved to a Samsung NVME drive.
I now use this SSD to store my games and it's still performing very well.
No noise, no heat issues. It just works.
Easily the best upgrade you can make it you want a performance upgrade without breaking the bank.
