How to read from 256GB PCIe-based flash storage

The logic board on the new 15 inch macbook pro retina is busted. I need to recover the data from my 256GB PCIe-based flash storage. Since the macbook pro doesnt boot up - there is no way for me to recover this data. It would be great if there is way to recover this data through a reader or using it as an external hard drive ?

OWC has their slimline, external Envoy enclosure for receiving the PCIe storage card from a MacBook Pro (2012 - Jan. 2013) models. In red ink, they emphasize it is not to be used for Fall 2013 or later MBP technology — so that solution is out.
Here is an iFixit guide on how to remove the PCie storage card from a 2014 MacBook Pro, in case you need to go there.
Out of town right now, so don't have access to a traditional SATA machine to test if Target Disk Mode still works with new 2014 PCIe machines.

How to buy the 1TB PCIe-based Flash Storage ?

Hi,
I own a MacBook Pro retina 2012/2013 with 256GB ssd,
I want to upgrade to the new 1TB PCIe-based Flash Storage.
I tried talking to apple support and was told they wont upgrade my macbook.
And that i should buy the SSD as a stand alone part and install it myself.
I have no problem installing it myself but I cant find it as a stand alone product.
The guy in support told me I can get it in the apple store. I went there and they dont sell it.
Anyone have the same problem?
Thanks

I want to upgrade to the new 1TB PCIe-based Flash Storage.
Honestly, do you NEED 1tb SSD?
You need to change the premise of your SSD use.
see here:
Your Solid State Drive and having enough space inside your Macbook Air & Pro
Solid State Drive usage premise, or the “more space / upgrade SSD” question
There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
A Professional Example
In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.
You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Slim USB3 1TB external hard drive
External Hard Drives
External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
1. Data backup and protection.
2. Redundancy for important data.
3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

Is the "512GB PCIe-based Flash Storage" on the new mac worth the extra cost? I am comparing with a refurb with better specs (faster CPU, larger hard drive) and from what I undersand the PCIe flash storage is the big differentiator in cost.

hello - i am considering two macbook pros
NEW - http://store.apple.com/us/buy-mac/macbook-pro?product=ME294LL/A&step=config#
REFURB - http://store.apple.com/us/product/G0ML1LL/A/refurbished-macbook-pro-27ghz-quad-c ore-intel-i7-with-retina-display
The refurb actually has a faster processor and a larger hard drive. From what I understand, the big difference in cost is the new macbook pro contains "512GB PCIe-based Flash Storage" versus the refurb "768GB Flash Storage".
Is the PCIe flash storage really worth the extra cost (and smaller size)?
PS - Also I believe the brand new one has 2 GB graphics memory as opposed to 1 GB graphics memory. I don't really care about that as much as I won't be doing a lot of video editing or gaming.

Some are some are not. Otherwise Apple has a ton of Mac's sitting around that have been returned by customers under their 14 day No Questions Asked return policy.
But they not just Returned and Resold. They go back to Apple, checked out (Tested) any parts that are not up to spec replaced and then repackaged in a plain white box to be sold as refurbs.

PCIe-based flash storage

Can the PCIe-based flash storage in the new Macbook pros be changed out?

Apparently it can. However there are no 3rd party options just yet.
OWC are working on one and have this great buying guid for the new MacBook Pro range.

Hard disk drive versus PCIe-based flash storage

I am trying to decide whether or not I want to get a regular MacBook Pro or a MacBook Pro with retina. I understand that the SSDs have less of a chance of failure (which is great because I've had a hard drive crash before) and that they run faster, but I don't know if I can deal with less storage space. If it's really worth it, I guess I would be able to fork over more for the higher storage SSDs, but I want to first know more about my options (ie, about how much stuff can I really fit onto each of the storage levels, does the storage amount go further on the SSDs, etc). Personal opinions are welcome! Thank you!

If your storage needs will fit on an SSD and you can afford it then it will speedup your Mac considerably.
Consider the size of your storage needs carefully. New rMBPs are not upgradable so you would need to live with the size of the SSD you would choose. How much storage do you use now on your Mac or PC? Are you planning to increase your media use (music, photos, movies)? Media is the biggest disk space usage for many users.
Personally, when I had a 128 GB SSD I was cramped. I upgrade to a Mac with a 256 GB SSD and now my 140 GB of used space fits OK. I have about 60 GB of music and photos and not much used for movies. I have a lot of old files going back a decade and half that I don’t bother to clean out because that would be a pain. My girlfriend uses only 60 GB and I plan to upgrade your machine to a 128 GB SSD. A 512 GB SSD would be wonderful but they are pricey.
On reliability: SSDs will survive shocks better but they have their own failure modes. I have had one fail in my Mac. So whichever way you go, backups are essential. Maintaining two backups is prudent.
13” rMBP prices: Purchasing at least 8 GB of RAM is prudent. If you count that in then a 256 GB SSD costs only $100 more.

Transferring data from 750GB backup drive to new MacBook Pro with 256 Gb PCI-e flash storage?

Yesterday my late-2008 aluminium unibody MacBook died - absolutely and definitively. I've tried SMC reset multiple times to no avail. However, it served me well for almost six years and it's now time to move on. I've decided to buy a 13 inch MacBook Pro Retina with 256Gb PCI-e flash storage. Obviously, it will come with Mavericks installed as the operating system.
When it died, my MacBook was running OS X 10.8.5, the original hard drive had been replaced with a Western Digital 750GB, 7200 rpm drive of which I believe about 350GB was used. I keep two x 1Tb Lacie Rugged backup drives, each of which has both Time Machine and SuperDuper Bootable Clone backups.
My questions are these -
1.     How should I proceed to transfer my data from my external backup drives to my new MacBook Pro Retina, given the difference in storage capacity of my existing backup drives and my new MacBook Pro?
2.     I have over 32,000 photos in my iPhoto Library which, obviously, consume a big slab of disk space. I'm not sure how I go about 'quarantining' the iPhoto Library so that it doesn't use all the flash drive storage.
3.      One of the Lacie Rugged's has a 'triple interface' - i.e. USB 2, Firewire 400 and Firewire 800. The other has a USB 2 and 2 x Firewire 800 (IIRC).    The MacBook Pro Retina has two USB 3 ports and two Thunderbolt 2 ports. I want to continue to use the Lacies as my backup drives. Am I better off to use the USB ports or should I invest in a Thunderbolt to USB cable? Does it make any real difference in terms of backing up (which, in my case, doesn't have to be all that speedy).
4.     What else should I be thinking about? I know I'm bound to have overlooked the most obvious problems but can't think what they may be ...
Cheers
Tricia

USB3 is backwards compatible with USB2, so you can use the old USB cables. For faster data transfer rates, Firewire 800 would be available using this adapter:

Firewire 800 is about twice as fast as USB2, theoretically.

Hi Nikhil,
    Thank you for the response. But what kind of streams can I feed into FMS input ? VLC supports other types of output, HTTP for example

How to read from 4 serial ports

How to read from text file?

I would like to read data (frequencies) already written in a text file. I will need read these frequencies one at a time to set the function generator (as part of my data acquisition application), acquire data that is in turn written to a file and then go back and read the next frequency from the file to repeat the process again. I also have another idea of doing the same, which is read all the frequencies from the text file and populate a table and a frequency value is picked from the table each time to go through the process mentioned above.
Can anyone suggest the following: (1) How to read from a text file, (2) What could be the most efficient way of solving my above problem.
I am a new LabVIEW user and any help will be appreciated.

Hi Research,
Depending on the format of the data file, there are a few options for reading it. If it is tab delimited, you may want to use the Read from SpreadSheet File VI which will read the file into an Array. You can then use the Index Array VI to pull out individual entries. If the files is ASCII but not tab delimited, you could use the regular Open File and Read File VIs. You can either read the file out piece by piece, or read the entire file into a string and then use the Match Pattern VI to parse out the different elements (there are actually many ways to do this - check out the Strings subpalette).

How to read from properties file

Hi,
I am using JSR 168.

I think i have mixed it up :)
I have looked at it again and believe you are using regular JSP portlets.
Can you tell what you want to achieve by reading .properties file. Are you meaning the preferences of the portlet or what exactly are you trying to do?
Reading propertie files is easy:
// Read properties file.
Properties properties = new Properties();
try {
properties.load(new FileInputStream("filename.properties"));
String myKey = properties.getProperty("yourKey");
} catch (IOException e) {

How to read from and write into the same file from multiple threads?

I need to read from and write into a same file multiple threads.
How can we do that without any data contamination.
Can u please provide coding for this type of task.
Thanks in advance.

Assuming you are using RandomAccessFile, you can use the locking functionality in the Java NIO library to lock sections of a file that you are reading/writing from each thread (or process).
If you can't use NIO, and all your threads are in the same application, you can create your own in-process locking mechanism that each thread uses prior to accessing the file. That would take some development, and the OS already has the capability, so using NIO is the best way to go if you can use JDK 1.4 or higher.
