I have dozens of their products and when I entered the market to buy a SSD for my computer I was pleased to be referred to them as one of the top names for SSD's. My headache began as soon as I started the drive and initialized the 'Data Migration' Software to copy my existing Hard Drive so that I would not have to reinstall OS and all my programs. ( I do not mind doing this, but prefer not to if I can help it ). Right after the drive cloning was complete and I had successfully restarted with what seemed like no problems I was thrilled with the boot speed ( roughly 3x faster than my old hard drive ) from powered off to loaded desktop in solid 20 seconds. Fantastic. Then I proceeded to launch a game and test out some load speeds. I started receiving blue screen windows crashes ( too this day I had NEVER had ONE on this computer) and could not pinpoint the cause. Since this was the only new piece of hardware in my machine I started with the drive. I was unable to confirm exactly what when wrong but within 3 days this drive had become the bane of my existence. Every program I would attempt to run would crash. Nothing could load on it and I started getting constant errors for any and everything under the sun. (I even got an error when I attempted to shutdown?!) finally the drive just stopped all together. I then began to get an error on my motherboard. After contacting EVGA customer support I was guided to reset my CMOS. Cleared my issue and then had to diagnose what the heck was up with this drive.This drive was inoperable after my reboot. Whatever the final straw was set this drive into what Samsung calls a 'frozen state'. This drive also came with another product called Samsung Magician which helps optimize to drive and customize certain settings but also allows the user to do a 'Secure Erase' on the drive to wipe it to factory defaults. Apparently for whatever reason you are not suppose to reformat the drive within any other program as it can wipe certain factory settings off the drive leaving you with a pricey paper weight. Since this drive was inoperable at this point I had to reformat and reinstall windows on my old hard drive and get to a working version of windows so I could fix my drive through Samsung Magician. --Skip ahead 3 hours -- (HEADACHE) Samsung Magician cannot secure erase the drive while it is in a frozen state. (figures!)There is a process it guides you through in order to 'unfreeze' the drive. While in windows the process did not succeed for me. The second option to unfreeze guides you to load a DOS program on a USB stick and restart the computer and boot from the USB stick. I changed all my options in my BIOS and for whatever reason this would not work. It was suppose to run the DOS program after exiting BIOS and would never work. (headache continuing). On to the third option of clearing frozen state! instead of USB stick you need a disk (CD or DVD) that is blank and burn the program onto. Thankfully my last option worked! but..... the DOS screen looked more like a garbled frozen screen of hieroglyphics. I had found a forum online that discussed how to reset it. It suggested that while at the garbled screen hit 'ESC' to pull up a DOS command line and enter SEGUI0.exe . well all that does is restart the program which is still garbled. after a call to Samsung's customer support they told me the issue is that with newer video cards the screen cannot display correctly unless you type SEGUI0.exe /s . IT WORKED. happy day. finally we are getting somewhere. The program that is running is just a DOS version of the secure erase function from windows. it runs before you computer has booted. you need to have the option in your BIOS turned on for 'hot plugging' whatever connection the drive is plugged in for the next step. it tells you exactly what to do and will guide you to PULL THE POWER CORD ON THE DRIVE WHILE THE COMPUTER STAYS ON. Then replug in the power connection after a few seconds. then restart the application with the previous command you entered. The drive FINALLY unfroze. I had to secure erase because there was no freaking way I was going to clone the drive again. (I am fairly certain the excessive amount of errors were coming from improper cloning of the system files for windows) Doing the old fashioned way with an OS disc install directly onto the drive. ---PLEASE DO NOT MAKE THE MISTAKE I MADE HERE AS IT WILL COST YOU SEVERAL HOURS OF YOUR TIME TO FIX--- WHEN YOU GO TO INSTALL WINDOWS WITH THE OS DISK DISCONNECT ALL OTHER HARD DRIVES I did not do this and did get the drive working but after some testing realized that it was using the system reserved partition from my old hard drive to boot because windows did not make its own system reserved file on my new hard drive. And with several attempts I could not figure out how to clone the system partition over. Also when you are selecting the drive to install the new OS onto click on the drive and click the button at the bottom that says 'advanced options'. 3 or 4 more options should come up. CLICK NEW and it will tell you it has to secure part of the drive space for windows functions. It should create the partition right there in front of you that will read on the screen as 100mb in size. THIS IS THE SYSTEM RESERVED PARTITION YOU NEED TO BOOT THE DRIVE BY ITSELF. after you see that continue on installing the OS until you are all updated and have all your programs re downloaded. Then you can shut off your computer and reattach your other hard drives (if you have any). If you computer decides to start thinking for itself it may try to boot off of other drives, just goto BIOS and select the new drive the be the first in the BOOT priority. So after 2 re installs of windows and a lot of consideration for introducing my hammer to my SSD I did finally get a usable, NON ERROR forming drive that is fantastic. Perhaps some people did not have this much trouble but I certainly did. One note I would throw in. As of my current install I don't even run the Samsung Magician Software anymore. seemed to be more of a headache than anything else and my drive works fine without it after my old school OS install. All and all I am still happy with my purchase even with all the trouble shooting, in my opinion it shows the value and quality of this drive that It can recover from just about anything..... except maybe a smash from a hammer. I really doubt you should have any kind of compatibility issues but in case you specs are close to mine you may purchase without worries. My computer specs are: --Intel I5-2500K (Sandy) Processor --EVGA Z68 ATX DDR3 2133 Intel - LGA 1155 Motherboards 130-SB-E685-KR --EVGA GeForce GTX760 FTW with ACX Cooler 4GB GDDR5 256Bit Dual-Link DVI-I DVI-D HDMI DP SLI Ready 04G-P4-3768-KR --2x--Kingston Technology HyperX 8 GB (2x4 GB Modules) 1600 MHz DDR3 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3K2/8GX --Windows 7 Home Premium SP1 64bit (Full) --Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW --Western Digital 500GB and 1TB Blue HDD (7200rpm) SATA III --Pioneer Electronics USA 15x SATA Internal BD/DVD/CD Burner with 4 MB Buffer BDR-208DBK --Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive (Black) Review: 840 EVO 250 MB upgrade to 4 yo computer Asus/AMD motherboard - I gave the unit 5 starts even though there were some problems I have not been able to overcome. I can't blame the problems on the drive as I installed it in a 4 year old home built PC, ASUS M4A 79XTD mobo, which has SATA II, and an AMD chipset. The BIOS has an option to enable the enhanced ACHI interface over IDE. ACHI has speed advantages for the SSD, and I get the BSOD when trying to boot using that option. It works fine in IDE mode, and it is still approximately 4-5 times faster than my Samsung 1T HDD. Boot time including starting the Firebox browser in Startup went from 4:13 to about 57 seconds. The drive comes with software that is instantly obsolete, I got the latest Data Migration, and Magician software off the Samsung site, the drive itself had the latest firmware. If you need a firmware update, the Magician software will do that for you. To install the drive I loaded a WD 250 MB HDD with a fresh install of Win 7 Ultimate, and a few other apps, like Firefox, but no MS Office, which loaded the WD HDD with 40 GB of data. The drive had all temp files deleted and was defragged. An external Thermaltake BlacX docking station used the USB 2.0 port to migrate data. The EVO SSD was recognized instantly by Windows with no problem, after using the Windows Disk Management program to partition and Quick Format the drive, which is well documented on Youtube. Data Migration is the first program you run, and it clones your HDD to the SSD. You have no choice here, it clones everything, or nothing. The data transfer was about 12 MB/s, my 40 GB drive took about 45 minutes to clone via USB 2.0. The SSD is then attached to the mobo using the old SATA cable, and it starts right up. Mine did not boot the first time and asked for the Windows install disk to repair the installation. After following instructions, it was fine. My drive would NOT boot using the recommended ACHI mode which I set in the BIOS. My ASUS mobo was stamped 2009 (four years old now) and ASUS tech support could not help me, and nothing from an extensive Google search helped me. The first 4 SATA 1-4 channels are controlled by an AMD chipset, and SATA 4-5 are Marvel. I now have the SDD on SATA 1, the Samsung 1T HDD (for data) is on SATA 5. Everything boots and works well, and is still very fast, even though I have SATA II and no ACHI. The Magician software gets loaded last, and will help optimize the drive and run speed tests. I did not run any tests, but the computer apps/programs are noticeably faster in every way. The drive formats out to about 238 GB, so don't expect the full 250 GB. In addition, to speed up and make the drive more reliable, Magician takes another 10%, recommended. After the OS was installed, there is another 200 GB usable. Some apps like MS Office will go on the SSD, and minor apps like utilities will be put on the 1T drive, as well as temp files and downloads. I bought the bare drive, so it was cheaper at about $140 for the EVO 840 250 MB drive. I had all the cables and docking station I needed, but I can see where the kit with the cable and mounting bracket for a desktop installation would be helpful. All of the few problems I had were anticipated because I did my research and read everything before buying, so there were no surprises and the drive works fine. When I am ready to upgrade the old mobo, I expect the drive will run at the faster speeds. If this is reliable and I think it will be, this drive is highly recommended. ## Features - Highest-quality components and engineering from the #1 memory manufacturer - Worry-free data security with AES 256-bit full-disk encryption - No moving parts means no hard drive spin ups, no noise and superior data protection - An innovative lightweight design that allows you to work smarter and play longer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E3W1726 | | Additional Features | Portable | | Best Sellers Rank | #2,447 in Internal Solid State Drives | | Brand | Samsung | | Cache Memory Installed Size | 512 | | Compatible Devices | Desktop | | Connectivity Technology | SATA | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.7 out of 5 stars 5,271 Reviews | | Digital Storage Capacity | 250 GB | | Enclosure Material | Nand Flash | | Form Factor | 2.5-inch | | Global Trade Identification Number | 08806085767553 | | Hard Disk Description | Solid State Drive | | Hard Disk Form Factor | 2.5 inches | | Hard Disk Interface | Solid State | | Hard-Drive Size | 250 GB | | Hardware Connectivity | SATA 6.0 Gb/s | | Hardware Platform | PC; Mac; Linux | | Installation Type | Internal Hard Drive | | Item Part Number | MZ-7TE250BW, MZ7TE250BW | | Item Weight | 0.05 kg | | Manufacturer | Samsung Electronics | | Media Speed | 97000 megabits_per_second | | Mfr Part Number | MZ-7TE250BW | | Model Name | 840 EVO | | Model Number | MZ-7TE250BW | | Number of Items | 1 | | Read Speed | 540 megabytes_per_second | | Special Feature | Portable | | Specific Uses For Product | Personal | | UPC | 785307931744 088727685137 797045615343 803982810632 045555971924 012302902999 887276851372 751014945145 632963215582 041114897766 031112555584 753456728591 013201088722 012304990673 021112254600 806293902188 | | Unit Count | 1 Count | ## Product Details - **Brand:** Samsung - **Compatible Devices:** Desktop - **Connectivity Technology:** SATA - **Digital Storage Capacity:** 250 GB - **Hard Disk Description:** Solid State Drive - **Hard Disk Form Factor:** 2.5 inches - **Hard Disk Interface:** Solid State - **Hard Disk Size:** 250 GB - **Installation Type:** Internal Hard Drive - **Special Feature:** Portable ## Images ![Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW - Image 1](https://m.media-amazon.com/images/I/81o8m6x9jpL.jpg) ![Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW - Image 2](https://m.media-amazon.com/images/I/81j+5m-YU4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Samsung worth the headache?.......

I got one for friend, one as a boot upgrade for desktop and the most recent one as replacement for office laptop. Overall, my 5th SSD disk so far, the previous two being Crucial 60gb and Kingston 120 gb (both are working just great after 3 years now). By the way, if you are wondering why SSDs are great, a. they add few years of life to some old machines that you would have discarded b. They make boot times extremely fast, so that shutting down PC isn't a pain c. Windows performance benchmark score jumps from 5.6 to 7.9. Its 7.9 because I think it cant go up any further. d. For tech enthusiasts and IT professionals, try running your I/o benchmarks for use cases you need fast random read/writes and see how things speed up. For large sequential reads, the HDDs try to catch up. e. no need to do defrags, though you may need to do some maintenance like over provisioning, which I will talk in a bit. here are reasons I love this 840 EVO drive, besides the price - 1. Convenience - Biggest point in favour of this drive. If you are replacing your current HDD drive with this, it cant get any easier. Connect the SSD through a USB adapter to a USB port (not provided with this packaging). Install the Migration software, and just clone your drive. It worked for me 2 times in a row on a desktop and a laptop. then, just replace the drive, install magician (optional if you want most from your drive) and you are done. Migration Software takes care of partitions and clones the drive as is. However, if you are adding this as a boot drive in addition to your existing drive, then this will not help. You have to install the OS on this drive. 2. Speed - Honestly, there is as much difference between various SSDs as there is between the SSD and HDD. When you run benchmarks, things will be faster on this one, but on day to day stuff like booting, opening files, and a typical consumer type of a usage, it wont make much difference. However, if you are a tech or geek, this drive has one of the fastest read/writes I have seen. If you have plenty of RAM, you can use Rapid to do "look ahead reads" and increase read speeds over time. I tried thinking about EVO vs PRO and felt EVO was good enough for general purpose, plus some occasional high performance IT needs. 3. Noise & Size - after replacing this, the laptop and desktop went silent. you can hear just the fan. Though most current HDDs are silent too, this is 0 db. 7 mm is perfect for laptops and notebooks. I hope these last reliably as my earlier ones. Few tips on configuration. In magician you will see a bunch of options. If you want more from your Samsung 840 EVO SSD spend time going through them, they are not tough, and you will get to know through the prompts. I use over provisioning at default, switched my laptop from RAID to AHCI. Win7 and above know how to handle SSDs so you don't strictly need Samsung Magician. ## Frequently Bought Together - Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW - SAMSUNG 870 EVO SATA III SSD 1TB 2.5” Internal Solid State Drive, Upgrade PC or Laptop Memory and Storage for IT Pros, Creators, Everyday Users, MZ-77E1T0B/AM - Crucial 32GB DDR4 RAM Kit (2x16GB), 3200MHz (PC4-25600) CL22 Laptop Memory, SODIMM 260-Pin, Downclockable to 2933/2666MHz, Compatible with 13th Gen Intel Core and AMD Ryzen 7000 - CT2K16G4SFRA32A --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/283429-samsung-electronics-840-evo-series-250gb-2-5-inch-sata](https://www.desertcart.kr/products/283429-samsung-electronics-840-evo-series-250gb-2-5-inch-sata) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-19*
