The same logic applies to hard drive sizes not listed here, including spinning disk drives. Time Machine backups, programs and everything else in OS X continue to work as before. All TarDisks shipped from our website are Pear enabled by default, however a user can choose if/when to Pear. Once Peared, computer performance is maintained and even often improved. Pearing is a permanent upgrade, and offers the only way to increase the size of your Macintosh HD designed to augment your MacBook experience.
How would you like to use it?
TarDisk comes in two* sizes: 128GB and 256GB. Both sizes can be peared with any compatible MacBook, regardless of that computer’s original HD size. *(Older 64GB TarDisk models are still sold by some retailers). Again, all MacBook Air/Pros support both the 128 and 256GB TarDisk Models.
The TarDisk family is composed of six separate designs. This includes variations in length and width which allow a TarDisk to live comfortably inside your computer without the danger of being lost or knocked loose. Our shortest TarDisk is 16mm and our longest is 22mm. If compared to an “SD card” a TarDisk is about half the length and generally more powerful. A full product compatibility chart can be found here with representative images to show size. Each TarDisk is specifically tailored to the computer it was designed for.
For selecting the correct TarDisk model, there is no ambiguity -- just download our simple and safe Selector software here, and feel confident knowing that your TarDisk will fit perfectly before it is shipped!
TarDisks are built around the same MLC flash NAND dies found in many SSDs and powered by high bandwith flash controllers developed for high definition media recording. TarDisks transfer data through the UHS-1 SDXC protocol at speed class 3 or above. The peak data transfer of the hardware alone is 95MB/sec which is about 1/5th that of a high performance SSD, however Pear more than makes up for that...
If Pear'ed, TarDisk acts as a compliment to your existing SSD. A Peared system maintains a "cache" on your SSD, shifting the read/write load and making any speed differential between TarDisk and your lighting fast SSD, almost unnoticeable.
However, just like any digital storage device, it is possible for TarDisk to fail and we strongly recommend that you always backup your data with your computer's built in Time Machine client. TarDisk uses the same MLC flash memory modules found in SSDs, where each block is rated for a minimum of 3k write cycles. (SSDs are 5k). Again, data failure on any storage device is possible and we recommend always backing up your system data with Time Machine and a cloud based option like this one here.

In this example a 256GB TarDisk has been Pear'ed with a 256GB MacBook Pro to produce 489GB free of 507GB. Notice that the MacBook Pro's SSD is 251GB while the TarDisk is a true 256GB, this is normal. Also notice that the colored bars are a reflection of each other, this too is normal and shows that both pieces of hardware are functional.
Finally the assigned names such as "Flash Storage" or "Secure Digital Disk" will vary depending on your MacBook Hardware which has been Pear'ed -- this too is normal. In the event that the sum of the two drives is not shown on the right hand side (i.e. you do not see 507GB or the combine equivalent) something in the Pearing process may not have completed fully and you should now review the trouble shooting steps in this FAQ.
Red-flags can be thrown to Pear if something is damaged or not responding properly. Please confirm the following checklist:
If after you run these steps above and still have issues with the Pear installer getting stuck on the progress bar or on the screen above, the next step is to repair your hard drive by restoring your computer from a time machine backup. You can make a TimeMachine Backup now, and follow the applicable steps in our guide here. After restoring, Pear should be run again and should work flawlessly.
This should solve your problems with corrupt storage, but if it does not, the next step is to either un-pear your computer (if applicable), or to replace your worn out existing SSD. Please proceed to "All other issues". A guide for un-pearing your TarDisk can be found here.
In the rare even that you are still experiencing issues trying to Pear your TarDisk or trying to run a computer which has recently been Peared, it is possible that something in your system has either thrown the Pear-Installer a red-flag or caused a kernel panic. In these instances we encourage you to visit the document found here, however due to your hardware configurations, it is possible that Pear is not supported by your MacBook.
*Please note that if you previously Pear'ed your TarDisk to your system and have since removed Pear, you will need to delete the EFI partition from your TarDisk, before it will show up in your finder. More info here. This only applies to those users who have completed the un-Pear process.

For TarDisk users, who can not reach their TarDisks' -- as you are aware, TarDisks are MacBook Model specific and range in length from 16mm to 22mm. In the event that you installed the wrong TarDisk for your MacBook, it is possible that this TarDisk is now seated deeply in your SD port making it difficult to reach with a fingernail/Credit Card. If it is necessary to remove your TarDisk, feel free to send a self-addressed and stamped Envelope to us and we will get a tool in the mail to you. The tool can be used to hook the TarDisk and pull it out.
If you have not run your computer down to 0% battery, but the TarDisk has still ejected, the first thing to try is shutting your computer down and with the computer off, unplugging and plugging your TarDisk back in TEN-Times. It is possible that if you rarely used your SDxc port prior to using your TarDisk, the pins in your computer’s slot are dirty and not making good electrical contact with the TarDisk. The act of pushing your TarDisk in and out may fix the problem. (Remember never use metal objects to remove your TarDisk)
If your [non-pear'ed] TarDisk is involuntarily unmounting from your MacBook upon sleep, there are software fixes for you here that will help as this is a setting in OS X.
Please note that if you Pear'ed your TarDisk to your computer, and received this error code, "Step 1" and "Step 3" are not applicable to you.
If your TarDisk is not sitting completely flush, it is likely that you received the wrong model or your are not inserting it correctly. We are happy to replace your recently purchased TarDisk with the correct model. Get in touch with us (flushfit@TarDisk.com) so we can help! Please include;
Pearing your MacBook is a simple process designed to be permanent. To prevent the potential for data loss, please make sure to follow the steps below carefully. Pearing makes edits to your operating system's core storage that results in a Macintosh HD that is additively larger. A full set of text instructions can be found here.
Enjoy your new Peared MacBook!
If you have additional questions, please review this guide and confirm that all steps were properly followed. In the event that you intentionally skipped any of the optional steps above (i.e. Step 8), this may be the source of problems you are experiencing. Please complete those skipped-steps now. If further assistance is needed, please review the full instructions, and in the FAQ follow instructions for Troubleshooting a Peared TarDisk.
Although the Pearing process is permanent, there may be instances where you need to remove your TarDisk for troubleshooting etc. In these cases the un-Pearing process is listed below and can be accomplished in eight steps.
If you run into issues, please follow the step by step guide here.
Note that after you un-Pear your TarDisk, the TarDisk itself will need to be re-activated before it will function properly again in a computer. To wipe the TarDisk clean, follow the guide here.
After a successful Pearing, your files are protected from third parties with physical access to your TarDisk without your permission. (For example if your TarDisk is ever to be stolen from within your Laptop without your permission, the files will not be readable). For more information visit our overview here.
After a successful Pearing, a shortcut icon to your Macintosh HD will appear on your desktop. This shortcut can be enabled or disabled using the preferences menu.
