The Samsung 840/840 Pro SSD thread

Samsung announces 3,000MB/s enterprise SSD

I wish engadget wouldn't write such rubbish.

The ink has barely dried on Samsung's last SSD announcement and the South Korean manufacturer has already made it obsolete by orders of magnitude.

That would be like saying that the new MacBook Air has made the iPad obsolete... when they are clearly not aimed at the same market. These new enterprise SSDs appear to be are aimed at people looking for something faster than 12Gb/s SAS SSDs in a single package.

Back to the 840 EVO, these do appear to be the successor to the 840 non pro. In theory, 19nm NAND is going to be the way forward (compared to existing 21nm) for the consumer market, so once production can meet demand, I can't see any reason for Samsung to keep making the 840, 840 EVO and 840 Pro ranges.
 
If anybody here has a Samsung 840 PRO 256GB in a Macbook Pro please drop me a line.

I would like you to do a speedtest if you don't mind, with NOT Blackmagic but instead this program:AS SSD Benchmark

I suspect my drive is a little wonky because of the results I got. Not the read write but the random 4K and access times.

I've been reading up and there are some factors that effect it but I am curious to see others results in the same situation. (MBP w/ 840 pro 256GB)

Thanks fellas

I'm considering replacing the HDD with a 250 gb SSD (Samsung 840 regular model). The cheapest I found in my country (Denmark, expensive as ¤&%& because of VAT) is 345 dollars, inclusive installation by authorised apple service providers. Thus I will not lose my warrenty (although it expires in a couple of months.

That price is not high. And you don't loose warranty by installing hard drives yourself.

That seems a bit much. You can get the 250 GB for €200 in the Netherlands. Let somebody send it to you or see if you can purchase it yourself.
 
Hey guys, I'm having problems with my Samsung 840 Pro filling up with files I cannot locate. Here's a little background info:

A few months ago, I upgraded my MacBook Pro 9,1 to two drives using OWC's Data Doubler. My main drive is a Samsung 840 Pro SSD. My intent was to use the SSD for the OS and applications. My secondary drive is the stock Apple 500GB hard drive.

Today, I was checking the useable space of both drives and I noticed that my SSD is nearly out of room because of movies, photos, and other stuff. However, because I was concerned about my SSD filling up too fast, I moved all of my movies and photos to the secondary drive many months ago. For the life of me I cannot find the files the "About this Mac" dialog box is saying I have.

How can I locate the files so I can move them? Are there any utilities, Apple or otherwise, that allow me to see a breakdown of the files the "About This Mac" dialog box is indicating?

Thanks!

UPDATE:

By the way, has any progress been made on a Mac compatible app utility for upgrading the firmware and enabling TRIM on a Mac?

Do you have a TRIM enabler running on your 840? If not it would be helpful in keeping it clean. Here are two choices, with the first being the most popular one.

Chameleon SSD Optimizer
Groth's TRIM Enabler

As for searching a drive for files and data usage, there is the one you found plus there are several others that are free and paid. I happen to use one called Daisy Disk, which is a paid one.

There hasn't been any update to the firmware update process on these and one still needs to burn and ISO disc for the Mac or install Windows in BootCamp and run the Samsung Magician software.

As I wrote, it is not expensive. His price is including installation. The price for the drive is 150€ in Denmark.

No, I don't. So could it be that the missing files are just garbage that was left over and has since been deleted or moved?

Its quite possible as TRIM is designed to help with garbage collection and removal. Since OS X doesn't support TRIM on third-party SSD's, such as the Samsung, you need to install it yourself.

When an SSD gets quite full, as you mentioned yours did, the SSD without TRIM will manifest its over-abundance of garbage files more noticeably.

Install one of those TRIM apps, restart the computer and see if you notice a difference in performance and additional disk space.

Okay, will do. Thank you. BTW, I just checked out DaisyDisk. Very elegant design. I'll probably purchase a copy of that.

Do you have Blackmagic installed? I'd be curious to see you run a benchmark on the SSD before installing TRIM and then benchmarking it after TRIM has been enabled and run for a bit.

I do not, but I'll download it and report the before and after results. Thanks again for your help.

No problem. As I mentioned, I'm curious to see how much difference, if any, TRIM has on your drive as I've not seen any before and after benchmarks from a drive that has been near full before.

I think that might not be quite accurate in terms of how/when TRIM works. The Samsung SSDs have garbage collection functionality in the firmware that runs when the drive isn't being hammered and it cleans up the data. The problem some folks have, as I understand it, is for drives that are heavily utilized and the built-in GC doesn't have a chance to run, causing the drive to "fill up" during heavy use. Enabling TRIM doesn't bypass the drive's GC, it triggers it to run even if the drive is in use and this prevents the garbage from filling the drive. I think I recall reading that the latest Samsung firmware improved GC and as such it's not a big deal to run without TRIM being enabled.

All that said, if the drive is just sitting there then GC will run and clean up the drive. If the drive is still reporting full then it's either a fault with the SSD or the drive is truly full with files and they will need to clean up their drive to regain space.
 
Which firmware Windows or mac ?

I have installed win8 under bootcamp to do the firmware update because I don't have and optical drive to burn the Iso to. Which firmware update do I download from Samsung- the windows version or the mac version?
 
SandboxGeneral said:
If you're on Windows, just install the Samsung Magician software and update the firmware from within the app.

I got the magician installed and when I launch it and it is "scanning for devices" windows looks for a problem and cant find one and my only option is to close the program.

I have a 2012 mac mini setup as fusion, could it be magician cant find the drive because its fusion? I checked under control panel and windows sees the drive under devices,

Also, even though windows is working I haven't "activated" it as I am also running it under parallels and my main objective for installing under bootcamp was to do the firmware update.

Why not just do it through the iso disc method?
 
SSD Upgrade

Hi, I own a unibody white macbook late 2009 (model 6.1) I already updated the RAM to 4GB some time ago and now I want to update for an SSD disk.

I'm thinking of buying Samsung 840 PRO 128gb, is this a wise choice? I don't think I'll have problems with compatibility and the reviews seems good, but I want to be sure before doing it

Thanks for any reply
Regards

The 840/840 Pro is a great buy and you will notice a great improvement in speed over the HDD.

All you need to decide is if the Pro is right for you. Typically the Pro is intended for enterprise and high production uses where excessive writes are done daily to it.

The non-Pro version is designed to last at least 7 years writing 10GiB per day and comes in less expensive to buy.

Thanks for the answer, the difference in my country between the 840 PRO (128gb) and the 840 (120gb) is 57 euros (~75 dollars), for a normal user (browsing, watching movies, programming) do you think that it's worth buying the PRO or it would be enough improvement the 840 ?

I think you can save some money and be perfectly fine with the non-Pro version.

Here's the BEFORE test. What do I need to do to enable TRIM? Just turn it on in Chameleon Optimizer?
