Top customer reviews
Performance-wise, the Samsung 840 is actually worse than the previous generation Samsung 830. On the Passmark benchmarks, it is slightly lower than the OCZ Agility 4 which uses asynchronous MLC NAND flash.
Right now, the top three SSDs (best selling and best reviews) on Amazon are the OCZ Vertex 4, Samsung 830, and the Crucial M4. However, all three of these SSDs are cheaper and they perform better than the Samsung 840. Eventually, the TLC NAND should mean that the Samsung 840 will sell for less because less NAND is used. However, it is not worth it right now. To be safe, I would say that you should wait until the drive is at least 10-20% cheaper than the three drives above due to the uncertainty of how it will perform in the long run.
One puzzling thing is that I couldn't find any mean time before failure (MTBF) estimates for the 840, while the MTBF for the 20nm MLC based 840 Pro is 1.5 million hours (lower than the 2 million hours for many 25nm MLC drives). Also, it is interesting that the drives are not 128GB, 256GB, 512GB. There are probably three reasons for this. The TLC NAND manufacturing process has lower yields so they have to "turn off" a portion of the cells to account for this. This is similar to what Nvidia does for their GPUs (16 functional streaming multiprocessors become GTX 580, 14-15 functional streaming multiprocessors become a GTX 570, etc...) Another possibility is that they anticipate that there will be more wear to the TLC NAND so that there is an unused memory bank to replace any dead cells. The third and most likely reason is a combination of the two, i.e. a portion of the turned off cells are nonfunctional due to the new manufacturing process and the remaining portion of the turned off cells are reserved for replacement.
I handle tech purchase decisions for my department and so I bought one Samsung 840 to test for due diligence but won't buy more until they become much cheaper.
As predicted, these drives dropped in price quite a bit. TLC NAND is about 25% cheaper than MLC NAND so that the price of these drives should converge to a ratio of around 75% of the price of a MLC SSD in the long run.
Wish I could have figured it out sooner. I wasted a lot of time and angst on this thing...
1) Should I use Samsung Magician software that comes with this drive?
Absolutely. That is the advantage of this drive. With many other SSDs, you can spend hours trying to optimize the drive digging through countless articles that leaves you hanging what you should really do. Magician takes care of this for you.
2) Magician always boots. Can I remove it?
Yes. It is not needed and performs no task after first used other than to inform you of updates and warnings. The best way to keep it from starting up is to find it in your notification area in the lower right. Right click on it and it will give you an option to remove it from the startup. (It doesn't remove it from the notification area until the next time you boot.) You can always run it from the 'All Programs' list if you want to run it again.
3) Should I run "Performance Optimization"?
Yes. This is your initial optimization and your OS takes over from there.
4) Should I run OS Optimization and how should I set it, Maximum Performance, Maximum Capacity, or Maximum Reliability?
Yes. Most people probably select Maximum Performance, but I will suggest selecting Maximum Reliability since it will extend the life of your drive and you will see no Real World performance difference that you will notice. Yes, benchmarks will indicated max performance runs faster but you will be very hard pressed to notice any difference in speed.
5) Should I update the firmware even if things appear to be working fine?
Yes. Unlike a number of other devices that suggest not updating your firmware unless you have a problem, this SSD will have improvements besides fixes incorporated in the firmware. Be sure not to run other programs while the firmware is being updated. (Note: This firmware update is not the same as the Samsung Magician update that requests to be updated from time to time.)
6) Should I use Over Provisioning?
Yes. In fact this is probably the first thing you should do. This will extend the life of your drive. The downside is that it uses 10% of your drive space. You should look on this as something that could/should have been incorporated internally, however they want to 'advertise' the largest size they can. This more or less provides swap space and a pointer in an area untouched and allows longevity and some speed gains.
7) When I go into Over Provisioning the 'Set OP' button is grayed out.
Wait. Just wait, it is probably calculating space. The software doesn't give you a lot of feedback that it is working at finding the space so give it some time. You may notice a very tiny icon next to the category indicating it is working. Eventually the button will be enabled. If it never enables then there is not enough free space on your drive that is NOT occupied by other files. This usually happens if you didn't Over Provision right after installing the drive. Your best bet is to delete unused files and use a program such as CCleaner to free up some space, then run Performance Optimization first, and then run Over Provisioning again.
8) When I go into Over Provisioning, I get the warning, "... Using a raw partition may damage your data..."
Don't worry about it. Everyone gets this warning and it can be ignored by 99.9% of people. Basically the message is for those who know if they have a raw partition. "Over Provisioning" simply makes a partition that is not accessible by you or your programs. Computer geeks may want to use this area for other things and this is a warning for them.
9) Should I use Rapid Mode?
It's up to you, but I never do. I have in the past, and I have experienced more problems with the ones I installed using Rapid Mode. I think it the real world, it does very little, but the benchmarks go through the roof getting everyone excited. Benchmark programs test your computer's speed to compare it to other computers and your past computer performance. Some Benchmark programs will not test drives that have been setup for Rapid Mode due to the "trickery" used to indicate a faster speed. This trickery is not necessarily to foil the benchmarks but have the effect of giving false improved speed indications.
10) When I run the Performance Benchmarks, the Sequential Read and Sequential Write it looks fine but the Random Read and Random Write looks low.
This is normal. The random read and write is most affected by your overall computer hardware design compared to sequential reads and writes. If you put this drive in a faster more optimized computer the random read/writes will increase. Keep in mind the bars indicated 'maximum' and not optimal or minimal.
11) Does it help to defrag my SSD?
No, never defrag your SSD. It will just decrease life and not in the very least increase speed. Defrag is designed for a mechanical drive. The logic is the same as pouring gasoline on your electric weed whacker… they are different animals.
NOTE: This concludes my Q&A for 90% of those installing this drive. The rest of the Q&A are for more advanced users.
12) How does the terms AHCI mode (Advanced Host Controller Interface), IDE mode (Integrated Development Environment), and TRIM (a command in the ATA command set) apply to an SSD?
When you first install Windows (WIN 7 and above) on a SSD, you need to be sure your BIOS is set to the AHCI mode. This allows WIN to install the correct drivers for the AHCI mode which will enable the TRIM mode to work. [ditto Mac OS X 10.10.4 and above]
TRIM manages an SSD similar to how Defrag managed conventional drives. TRIM keeps the drive optimal speed and longevity.
The technology is much different with SSDs. For TRIM, consider a single memory location as a "cell." Cells have a limited lifespan. They die after being accessed many times. Unlike conventional drives, a cell must be erased before it is written to and that is slow, hence they move data around often because the access of the data is the same if it is at the far left or far right. It provides for an even use of cells throughout the life of the SSD.
TRIM is only enabled by AHCI drivers and AHCI drivers are only installed automatically when the BIOS is set to AHCI mode, instead of the IDE mode (mode for older conventional mechanical drives).
13) I don't have an AHCI mode in my BIOS, but I do have a RAID setting and I understand it will work the same?
It may, but not necessarily. It depends on the "chipset" on your motherboard. This is something you must research for your model of motherboard and in particular the generation or series of your Intel chipsets.
14) My computer will not boot the SSD unless I have the BIOS setting in IDE mode.
Most likely the SSD was copied from a hard drive that was installed in an IDE mode computer.
You have a few options:
a) Leave it in IDE mode, but you won't have the advantage of TRIM.
b) Search the internet (change from IDE to AHCI after installing Windows) to see how to change the registry, however keep in mind that this doesn't fix everything, it just allows it to boot. Opinions differ but most agree a full new install is the only right way to insure the AHCI features are supported.
c) Start over. Remove the partitions and start from scratch setting the BIOS to AHCI mode and installing Windows 7 and above. The copy and reinstall your programs from scratch.
15) My computer gives me the BSOD (Blue Screen of Death) after I used Samsung Data Migration software to copy over my old hard drive and installed it in my new computer.
Change your settings in BIOS to IDE and see if it will boot and then read the previous Q&A.
16) What was the story of older Samsung SSDs slowing over time?
Some Samsung SSD using the TLC (triple-level cell) concept, they found caused old data to be slow at accessing over time. All SSDs of this generation had similar problems to varying degrees, but it appears Samsung was the first to address this situation quickly with a firmware update that was basically a bug fix. However, after testing they foresaw other shortcomings down the road and released a second firmware update that appears to have fixed the decline of speed. If your firmware is up to date, you are good.
17) Samsung Magician says I need a firmware update but it gives me an error or says it can't be done. I understand that I can manually apply a firmware patch not using Samsung Magician. Should I do that?
You probably have a computer using an AMD controller that conflicts with the Magician firmware update, and there is an easier way. You check if you have an AMD controller by going to your Device Manager and selecting "IDE ATA/ATAPI controllers" and look for AMD.
If you have the AMD driver then to install the firmware, you need to install the Microsoft driver temporally.
Do this at your own risk, but I will outline the method. Before you look online you might see if it's already on your computer by opening up the controller in Device Manager, locate the AMD driver (e.g., AMD SATA Controller), right click on it and select properties. Then select the Driver tab. Select Update Driver, then select 'Browse my computer…', then select, 'Let me pick from a list…'. If you are lucky you'll see the Standard AHCI Serial ATA Controller. Select it and click on Next. You will directed to reboot.
Once rebooted you should be able to run the Samsung Magician software and update the firmware without errors.
Once you are done with the firmware update, reverse the changes using the same method above but select the "newest (if you have more than one)" AMD driver.
I really like these SSDs as they are a good value for the price. This technology has been booming and there are tons of improvements and breakthroughs almost monthly. I think the biggest mistake most people make is trying to squeeze the extra little bit of speed out of an already blazing fast hard drive. If you absolutely must gain the little additional speed possible, then spend twice as much and get a higher end drive. There are plenty on the market of the same size with double and triple the price, with their claim of more reliability and a little faster speed. In my opinion if you don't need it in a server this level of SSD is fine. I would suggest that most people will do better with a minimum of 250GB and above. The 120GB is just a little small for most people's needs. Feel free to respond if you see changes that I should make.
