• Samsung 840 Pro Series 128 GB in Studio 1737?

  Probably a stupid question, but I need to know before making a purchase. The Samsung 840 Pro will work in a Studio 1737? What to look for when buying an SSD to ensure it will work with my computer.

  Sorry if this is Basic. learning of MI

  It will be, yes - but unless you have future plans to move the drive to a newer system, you will have to pay a price premium for this drive that will not be displayed in performance, due to the slower SATA controller in the system you have.

• Allows you to TRIM on Samsung 840 Pro SSD without danger?

  I'm still in Yosemite because of compatibility issues with some software that we use at work. I saw OS x 10.10.4 you can activate the TRIM of the terminal, which would help a lot on my MBP of 2011 with a 840 Samsung 256 GB Pro. When I bought it, it's the tip about 500 MB/s as well read/write - excellent! But more recent benchmarks shows a sad note:

  

  It's obviously a part of poor cleaning result and the lack of support from TRIM on OS X. whereas it's easy to activate the TRIM, I'm not so sure that it is safe to turn it on. There are many items from 2014 and 2015 mentioning bugs in the firmware from Samsung regarding FILLING in queueand bugs in the Linux kernel regarding sequentialTRIM that created a different problem. Most people would have problems because of the firmware on the disk problem.

  -Where are we now? Is this even a question? I can't find a more recent post on what are the potential risks. I do a lot of video Import/Export at the time (where the wish for a faster drive) and I can't risk of corruption. We're talking perhaps about 50-60 hours of material, all the corruption in exports would probably take long to notice (before anyone looks at everything).

  A quote from the post to MacRumors: 'so if you have a modern Samsung drive, it is important that your operating system uses regular sequential TRIM. Linux is the only OS that uses queued. All versions of OS X (same El Capitan) and Windows (last) always use sequential TRIM and will continue to do so in the foreseeable future. »

  So is it true? I can easily activate topping on my Samsung SSD, no risk that I'm suddenly stuck with random corruptions on my files in a few days/weeks?

  As far as I can see 'about tech' article there is no problem on Mac, only Linux distributions that uses queued TRIM, which the Samsung 840/850 readers wrong informs that it supports. Sequential TRIM and Mac/Windows should not see any problem.

  "Samsung TRIM questions seem to appeared only when used with the TRIM controls in queue." OS X uses only sequential TRIM of orders at this time, so allowing the FILLING with the line of Samsung SSD should be OK, such as reported by MacNN. »

• No AHCI? Samsung 840 Pro? HP Dv7t-7300

  Hey guys, I noticed today that by virtue of the HP BIOS options is an AHCI option. They don't let you change to all modes. I have a HP Dv7t - 7300 laptop. I bought a new SSD for performance gains, but I was wondering will I get full use out of it. At first I was getting really good at reading and writing speeds, but it slowed to about 300 now. Does anyone know if I should just leave it as what or try to configure for optimal performance. In Device Manager, I see only a driver who says RAID SATA AHCI not. I have attached the photos below. The old hard drive is now always in the laptop but on the second SATA port. The magician of Samsung software also tells me that AHCI is not active. Is this normal for the SSD performance fluctuations?

  The BIOS in double bay dv7 models is not set to RAID, AHCI, and cannot be changed. But don't worry it is ahci compatible RAID. Files of native and other functions necessary to support an SSD are present. I would be not too wrapped in reference SSD speeds. 300 Mbps is very fast. How does it feel?

• My laptop Dell XPS 17 (L702x) does not recognize an SSD pro Samsung 840

  Hello

  I buy all my first SSD for my laptop Dell XPS 17 (L702x) (8T7CQS1). I managed to install the Samsung 840 pro (MZ-7PD256BW) at the HARD School of XPS drive, but the BIOS does not detect as a second HARD drive.

  My BIOS version is the most recent: A19 (26/10/2012), I tried to load the BIOS default settings, but no change.

  The SATA in the BIOS mode is AHCI.

  What could I do with them?

  Thanks, if you can help me,

  Hi Kris,

  Traction test drive 1 and put the SSD in this slot. Then boot in the BIOS to see if the drive is detected.

• T440s kills 840 Samsung SSD pro

  Hi all

  I have a T440s new, bought with HARD drive. That I wanted to use a reliable SSD, I bought a Samsung 840 pro, I already running in another system. That's when the problems started. In a German Forum several users report similar problems, so I just wanted to give a summary here, so that perhaps the international community can help. I consider myself as being an experienced user, built the various PC systems in recent years and currently have a desktop running with Samsung 840 pro system. Here are the details:

  I installed Windows 8.1 (several times, first clone HARD drive and later after recurring problems, clean full install win DVDs of 8.1), value UEFI Bios only + Intel Quick start disabled before installation.

  The question now is with the SSD I get constant HDD (visible in EventViewer) mistakes, while usually after a few hours of operation, the operating system is damaged to the point that it cannot start more. I should mention that the same system is running stable with the original HARD disk. First I thought that it is a faulty SSD and I replaced it by Samsung. However, with the new SSD replaced I am facing the same problems. Earlier this year, I have corrected a problem on a desktop with 840 pro where symptoms were similar. In the case of a desktop system, the issue could be fixed by replacing the SATA cable (which is obviously not an option on the T440s).

  And Yes, I use the latest firmware SSD, the BIOS update, the drivers of Lenovo. Now, the problem is that I do not seem to be the only one with these problems. Other users in similar problems Thinkpad German forum report not only on Windows systems, but also on Linux installations (we even got the motherboard replaced by Lenovo and yet, it does not solve the problem).

  I contacted Lenovo support and they told me that they support only of original Lenovo SSD. I must say that I am really disappointed that my new system from a renowned manufacturer constantly does not work with one of the most widely used SSD. Currently, some users in the report of the German forum they have better luck with Samsung EVO SSD. However, after this experience, I really lost confidence in the T440s. If the design should have problems with Sata 3, I don't know if I can trust this laptop in a business environment.

  Comments/suggestions very welcome.

  Kind regards

  Frank

  PS: Here is a reference (at least two other users reporting this issue in this forum, here, in German, however)

• SAMSUNG SSD Pro 840 died after two days of Thinkpad Yoga

  I replaced my new Thinkpad Yoga with Samsung 840 Pro SSD and he died two days after I see the core in something Page error, and I couldn't start later. I am connected later this SSD to USB port on my other laptop and he was dead. Lenovo Diagnostics failed for SSD drive as well.

  I would like to know if anyone of you tried Pro 850 with Thinkpad Yoga and was happy with it?

  I have a S1 of Yoga in which I recently installed a Samsung 850 Evo (not the 840, not the Pro 850, but they are similar). So far, he's doing much - he has been here for about 2 weeks now.

  It is Windows Pro 8.1 with full disk encryption enabled.

• Pro SSD Samsung 840 overheat

  I have an Inspiron 17R and installed a Samsung 840 Pro SSD 256 GB drive.  I work with a video presentation software and while rendering video the application often breaks.  I have had many interactions with the software company, and they claim that there are no problems with the software.

  I use a Notebook Cooler ZM NX2000, but the drive still seems to be pretty hot.  As a test, I had a small desk fan which I made on the left side of the laptop when running the rendering process and the process is completed.  Accordingly, I suspect that the drive is overheating.

  I made Diagnostics and here are some results:

  High speed rpm: 5100

  Max speed rpm: 2600

  Thermistor high CPU 65 c (149F)

  High video thermistor 54 c (129.2F)

  Someone had a similar problem?  Suggestions or other options?  I asked in Samsung too, but thought I would check with the experts here :)

  Thank you.

• Many BSOD after installing Samsung SSD 840 pro in ThinkPad Lenovo R60

  Have an old Lenovo ThinkPad R60 with screen SD that I won't. After installing the Samsung SSD Pro 840 the BSOD started coming, now every week, the last one on today. I don't see the option to download the dump anywhere file, so I enclose a picture with - maybe - some info.

  Can anyone help?

  Thank you

  okinchi

  

  Not at all surprising that involved C:\WINDOWS\SYSTEM32\DRIVERS\SYMEVENT. Pilot of the SYS Symantec event library.  I remove it and use MSE in its place

  Symantec is a common cause of BSOD.

  
  
  I remove and replace it with Microsoft Security if you are using Windows 7 and if you win 8 or higher, use the built-in Defender.

• HP Pavilion dv7-6c95dx - do not pick up the Samsung 840 Evo SSD for clean installation

  Hello

  Laptop model: HP Pavilion dv7-6c95dx

  I bought a new Samsung 840 Evo 500 GB SSD and going on to replace the main HARD drive. Tried to install Windows 7 Ultimate on it using the USB bootable Win 7, it loads the installation and starts ok and then he asks to load the driver for any device and gives you an analysis of the option to see if there is any storage device to select for installation. It clearly shows that it does not pick up the SSD.

  Unfortunately the bios insydeh20 V3.5 has no possibility of even check if it is detected or so.

  What do you think is the problem? The BIOS update would solve this issue? or is there any other work around that.

  Thank you

  Mike

  Before I went ahead with the method you suggested, I tried updating the Bios with the latest version and voila... system picked up the SSD and all is well now.

  Thank you

• Z500: Samsung 840 evo does not (under windows)

  Hello

  I replaced the build-in the hard drive in my Ideapad Z500 with a brand new Samsung 840 evo and tried to install Windows 8.1 on it.

  (I also replaced the dvd player with a hard drive caddy, where I put the old hdd)

  Unfortunately, I can't install windows.

  Whenever I try to format the primary partition, nothing happens for about 3 minutes, and then he throws the error code 0 x 80070057 "unable to create partition" (actual description is in German)

  When I boot from the old hdd and try to format the SSD inside windows, it does not either.

  Magician tells me, everything is fine with the ssd, but it cannot perform all tests, because there is no volume

  SATA controller mode is AHCI.

  Boot mode is UEFI.

  Here's what I've tried:

  -In installation: diskpart-> disk list-> select disk-> own-> convert gpt-> exit (exits without errors)

  -Manual partitioning with parted magic

  Someone at - it an idea that doesn't require you to disassemble the laptop new? That's what I want to only try if all else fails. I was very careful when you replace the readers and did not notice any physical damage, suspicious sounds, etc.

  
  

• Solid State drive Samsung 850 Pro

  I want to add an SSD Samsung 850 Pro for a HP Pavilion Elite e9280t intel i7 - 920 (2.66 ghz, 1 MB L2 + 8 MB of cache shared N3), 2 TB 7200 RPM / min SATA 3 gb/s - two 1 TB hard drives. An SSD will work with my setup?  Thank you Gary

  Hello

  The e9280t of HP has only SATA II ports, so all SATA III SSD will not reach its full performance potential.  A more cost-effective alternative is to look at the EVO of 840 Samsung which is very popular in many magazines of the PC industry. I know that the Samsung 840 EVO works on your PC.  Watch a 250 GB or more large model.

• EliteBook 850 G1: Elitebook 850 G1 and Samsung 850 PRO 512 GB SSD

  Hello

  I recently bought a new Elitebook 850 G1 a retailer authorized HP here in Germany. It turns out be a very fine machine so far.

  Just a little thing I noticed is the following:

  I exchanged the original 250 GB SSD (A Samsung 840) supplied with the notebook for a Samsung 850 PRO 512 GB SSD.

  It made me lose the UEFI chart UI system diagnosis. Only the base system diagnostics are available (similar to BACK black and white screen).

  Apparently BIOS EliteBook doesn't "recognize" the PRO 850 as supported even if the player works absolutely fine in laptop computer, running a new installation of Windows Pro 64 bit smoothly 8.1.

  Is there some sort of whitelist of device in the BIOS? Is it possible to get other permutation Diagnostics advanced system back to the original SSD? Maybe some update BIOS?

  Already, I run the latest BIOS of G1 EliteBook 850 as available by HP driver and download Web site.

  Not that this is a crucial issue given that the laptop works well, but it's kind of worries me nonetheless.

  Thanks for responding.

  Diagnostics UEFI advanced is actually contained in a service partition on the hard drive so unless you cloned all partitions on the old disk you may have failed. Fortunately, it can be downloaded and installed on the hard drive or you can even make a thumb drive bootable UEFI.

• Alienware 17 R3 with Samsung 950 Pro

  Boy I was wrong, he refuses to detect the PRO 950 and refused to start at all. I have the 1 TB back out, just so that I could start again under the windows installed on the Pro 950. And before you say anything yes I disable the startup of windows for the 1 TB option in the Bios.

• Dell XPS 13 2015 and update of Samsung 950 PRO m2

  When I ordered my Dell XPS 13 May of this year, I ordered it with a disc of 256 GB knowing that I would upgrade eventually to a disk of 512 GB once the new discs of NVMe m2 were out. I didn't do well capture the variations in m2 and when I pre-ordered the 512 GB Samsung 950 PRO NVMe I expected to pop in and go. No luck. I should have known that they would not make it as simple as that... :-(

  The drive is compatible physically of course, but has the "M" key edge connector, while the drive I pulled the connector edge key "B & M. I am running the BIOS A05 on the Dell, but he can't see the PRO 950 drive at BIOS level. The integrated test tool indicates "no hard disk". If this seems to be a BIOS problem.

  Anyone have any ideas? Is it a question of Dell, he argues with a new BIOS update? Or it will never work because the XPS 13 is not compatible with this generation of pilots of M2? Looks like I need to go back to what happens, but if Dell eventually allows, I may buy it again.

  If it won't work, any suggestions on a 512 GB drive that works? Samsung XP941 or XP951 will work? An idea about the difference between the two (the XP951 is $50 + more).

  UPDATE: this player is not compatible with the Dell XPS 13 and probably will never be because of energy consumption (5-7 watts). You just don't want a storage device that power in your laptop. The Samsung SM951 512 GB is the best player at the moment.

  For the record, I was able to get the 950 is recognized Pro to install windows 10 on simply turn on the legacy startup options.  Once turned on my windows install USB he saw as installable media.  After installing the drive had an EFI boot sector, so I was able to disable legacy startup.
