• Samsung 840 pro 256 GB or not so great raid of 4 disks tray?

  I'm debating a 'hand' project disc I thought 4 seagate 1 TB are on my motherboard in raid 5 (asus p9x79 pro).

  Now, I know this great as raid controller used his on the mobo - but what sort of speeds will I get if these 4 disks in raid 5? It tempt me to just use a samsung 840 pro and save it instead, but this isn't my first choice.

  It also won't be a temporary solution anyway until I get enough money for a disc of 8 dedicated a whole raid controlled upward (which I assume is fast enough).

  PS also space is not a problem for me - I stay normally less than 100 GB per project.

  Thank you!

  A raid5 4 disc on the motherboard will be probably about 150-180% faster than a single disk and with drives of 1 TB Constellation ES, which translates into about 225-270 MB/s sustained transfer rates. Mind you, it is a guess, since I've never tried a parity raid mobo, but based on what I heard from users who used on-board raid. On a dedicated controller, you would see figures around 360 MB/s for the same configuration.

• 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?

• 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.

• 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,

  Kris

  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.

• 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.

• 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

  After receiving my new Alienware, I decided to install a Samsung 950 Pro. After a lot of sweat, blood and tears and TONS of frustration, I was able to get 10 Windows installed as well as most of my games. I felt he was finally sure to re - install the HARD disk supplied with the notebook 1 TB.

  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.

• Satellite Pro A120-128 - HARD drive upgrade

  Hello

  I'm seriously exhausted on HARD disk space and want to upgrade my HARD drive in my Satellite Pro A120 128. Is there a maximum size that I can update? This model takes SATA or IDE?
  Any suggestions on make & model disk HARD upgrade to?

  THX!

  Normally it should not be a problem to use a HARD drive this lager s like 137 GB because as much as I know there is no limit of capacity on SATA interface.
  But as said Akuma, test it before buying this drive.

  However, an IDE HDD does not fit in this notebook

• Satellite Pro L300-128 - startup problem

  Hi all

  I recently bought a Satellite Pro L300-128 GB specification, that has a Celeron M550 running Windows XP and a construction date of the end of June 2008. I have a problem with the switching on of the machine if it has been turned off for a long period of time.

  Basically, if the AC cable is inserted into the computer laptop and plugged in, the green light turns on, but pressing the button it does nothing. By the process of elimination, I have found that, after a short period of time (say 15-30 minutes) if (and only if) the AC cable is then removed from the laptop, it lights up then!

  Plug the AC cable, while the laptop is on, do not cut the machine and charge the battery as usual. The battery life seems very good, if a little short (say 1.5 - 1.75 hours when used "constantly").

  If the computer is restarted, it lights again very well - if it is turned off and left for a few minutes, once again no problem. But, if she is not with the battery fully charged and left all night - it lights again in the morning.

  Now, as a new machine, I'm wondering if the battery needs a long initial load (such as a mobile phone)? Nothing is said about it in the manual. I have not yet checked if the battery down completely himself during the night. I haven't run the battery to the laptop for a long time (say all day) to 'trickle charge '. I don't know if the period from 15 to 30 minutes to get the thing started is once again because the battery is completely discharged during the night (I need to check the BIOS to see if "Wake up we LAN/wireless" is activated)-anyone know how long a fully discharged battery must be charged before that the machine will let you start it?

  Under the machine, there are two battery release buttons and it seems loose - I don't know if it's related, but can't see how. Moreover, when the question arose (during the first delivery the laptop), I removed the battery and tried power upwards of food, but nothing to do.

  I ran all the software updates (chipset etc) I can find on the download page, the BIOS version is 1.40 (last) of the factory.

  Any suggestions would be welcome before I have use the service of repair under warranty for the first time! I don't know if it is related to the fact that the power button seems to be a micro switch rather than a good button/switch in the conventional sense of the term, i.e. you can 'feel' it do something!

  Thank you very much
  Richard

  Hello

  If you have purchased a new laptop, the battery is empty and needs to be charged in the first place.
  You can also connect the adapter to the laptop while the battery is empty and the laptop should also lights up properly.
  The laptop must also run without the battery and using only the AC adapter.

  It should also be possible to put the laptop by pressing the power button for about a second, if this is not possible, a malfunction of the laptop could be possible.

  In such cases, it s always advisable to contact the local ASP for a verification of the laptop.

  I mean your laptop is under warranty and if something is not wrong with the machine so everything must be replaced free of charge

  In my opinion, the laptop must be checked!

  Concerning
