The Samsung 840/840 Pro SSD thread

[Amrives]

can we gets some screenshots of the 128gb 840 pro's speeds? I want something to compare mine with. tx

Also do you know by chance if I need the firmware if I'm running Trim? I read the firmware only fixes/enhances the 'dirty write' issue.

Thanks again!

Trim cleans dirty blocks, so assuming Trim Enabler works as promised, then your drive should be relatively clean. So no, the firmware is just because my hands are itchy

Isn't that a lot slower than its supposed to be?

Write Speed is definitely lower than I was expecting, but Read Speed isn't too bad. I'm curious if I have something configured wrong or if it's 'cause it's not an 840 Pro?

Speed is correct. Just read the specs of the drive: http://www.newegg.com/Product/Produc...ng%20840%20120

Sequential write is as fast as Samsung announced.

Thanks for the info! So I guess it was just 'cause it wasn't a Pro. I'm still happy with the real-world performance of it.

The difference in write speed is insane for the different capacity. You have the 840 non pro 120GB. I have the 840 non pro 250GB. We both have the same laptop with the same 16GB upgraded RAM. I have FileVault turned on so I took a 50MB/s write speed decrease.

This makes me want to buy an 840. All I hear about is complaining that these drives don't last as long as the Pro. Pros last something like 20 years and the 840 will apparently last 7-11. What's so bad about that? I've never had award drive more than 5 years.

Just want to say thanks for the advice and information on the Samsung SSD drives.

Installed a 840 Pro 512gb drive this morning in my new (from the APPLE refurbished store) MBP late 2011 17" and everything seems to be going well. Silent (of course), fast, and I'm feeling comfortable and assured after reading here about this drive. My speed test maxes out with blackmagicdesign's speed tester so seems to be all well.

Best

Just bought a 250GB 840 SSD. Should be here on Monday. Will be replacing my current 500GB HDD on my early 2011 15" MacBook Pro.

Hi all,

Pardon my English, not a native English speaker.

Here sharing result of my mid 2012 15" mbp configured in RAID 0, with 2 x 120G 840(non-pro, FW:6B0Q). System memory upgraded to 16G of RAM.

Setting the RAID up wasn't smooth than I thought.
The SSD (A) in the main drive partitioned smoothly, but I had major problem partitioning the one in optical bay, SSD (B). Disk Utility keep showing "File system formatter failed" halfway through the process.

Long story short, I swap the two SSDs around, with SSD (B) in main and SSD (A) in optical bay. I was able to partition SSD(B) smoothly. the rest was pretty straight forward.

cheers

That is pretty impressive Read speeds!

There have been some issues with SATA-III SSD drives installed in the optical bay attributed to "noise" in the cable or interface. These were on 2011 MacBook Pro machines, I don't know if they have resolved this with the 2012 generation.

Some posters have reported some success by adding additional shielding to the cable. Most posters here are only adding a SSD to the existing Hard Disk, and have circumvented the issue by installing the high speed SSD in the original disk location, and putting the much slower Hard Disk in the optical bay area with a mounting tray (optibay). OWC recommends putting only SATA-II SSDs in the optibay for best results (some SATA-III SS drives can be programmed to only run at SATA-II speeds).

Although Apple may be aware of the SATA-III issue with the optical interface, they probably don't have a lot of urgency to fix the issue since all models only ship with really slow optical drives in that location.

Good luck with your project ... RAID-0 SSD in the MBPro would be really nice!

That's pretty impressive speedup!

Hi folks,

I have a 2010 MacBook 13" Intel Core 2 duo and my read speeds doubled but it's only 110 mb/s instead of these 400+ speeds others are posting. Is that because my old mbp hardware? Loads/saves/startup/shutdown etc.. are so much faster than it used to be but my disk speed results are pathetic compared to some of these!

That's because your MBP does not support SATA III, The same happened with me

Hi, first of all greetings to everybody because I'm new in the forum.

I've recently purchased an 840 (non pro) 250GB for a MacBook Pro mid 2009 (SATA2) and I'm very happy with it.

System starts in 18 seconds, and applications launch soo fast. The unit works fine (at least to me)

But I have some question. I can hear the SSD when I put the ear in the MacBook. It's a very little noise, but I can hear it.

For sure, I open the laptop and put the SSD unit to my ear, and yes, it make noise, a very very little noise that I can only hear when I put the ear.

I just want to know if this is normal. as I say it works great, but I'm worried that might be defective.

Searching google, seems to be normal in SSD units, but there are people who maintain that the SSD do not make any noise.

Any clarification is appreciated.

On the other hand, I wonder if anyone in the thread has the same configuration that I, to compare bechmarks. Is just to know that I have correctly installed.

As I say, is 840 250GB non pro with a macbook pro SATA 2 (mid 2009)

Very thanks to all

Regards

What is the consensus on enabling TRIM on the Samsung 840 SSDs?

Installed the Samsung 840 500GB (standard, not PRO) in the main HDD bay of a MacBook Pro late 2008 and getting 210MB/s write and 270MB/s read. Same exact speeds with TRIM enabled via Trim Enabler app. Not concerned with increasing speeds - this is an aging laptop that I'm trying to squeeze more life out of. More concerned with reliability, extended life, daily use, etc.

Thanks for replying, Howard.
I just realized the 128GB 840 (non pro) advertised 130MB/s write speed, and I got 26xMB in my RAID 0 setup, which adds up. thanks~!

[Amrives]

I want to get another 128gb 840 pro to put in my '12 i7 mac mini, are there really any cons to having the drives in RAID0 format? Does anyone have this setup already? Ive seen 2x256gb's spoken of but not 2x128gb's. I assume write/read speeds would be close to 720mb/s write and probably 950mb/s read. maybe higher but my singular 128gb Pro only gets about 360mb/s write and 490mb/s read so figure a little less than twice that? Also, whats the deal with TRIM while in RAID with 2 SSD's?

[pprior]

Installed the 840 pro 256GB in wife's mid 2009 MPB.

Getting 204mb/sec writes, 256mb/sec reads, consistent with the interface on this machine.

I am pissed that there is no firmware upgrade tool for mac. That is crap and I wouldn't have bought it had I known that in advance. Firmware updates are important for SSD and for them not to support mac computers, well we should not support them.

So although this works fine thus far, I would advise others to look elsewhere to a company that actually supports mac.

Agreed, some have suggested booting into Windows via Boot camp if you have.

Correct me but I don't think you need the firmware update if you have trim enabled. The firmware update only addresses the 'dirty write' issue.

But yes Samsung needs to support mac/linux if there will be more firmware updates..

Hi,

i installed an 840 Pro 256Gb in my Early 2011 MBP 17" (2.3GhZ Core i7, 16Gb RAM) and get these results - quite lame compared to what i see in this thread.

Profilers states full 6GB link speed - can anyone bring me or better the SSD up to speed? Did i miss something while installing? Firmware is not the latest, the one with the 3 in the revision number...

Someone correct me if I'm wrong, but I believe your model may only be equipped with a SATA II connection, which is going to bottleneck the speed of your drive to what you see. You would need a SATA III connection in order to achieve some of the speeds you have seen posted here, which are in line with some of the advertised drive speeds.
