When I migrated to SSD on my Mac mini, I kept the original 1 TB hard drive to store my old Mac OS data. That was just in the SSD migration failed. After two weeks of non-event, it was time to blow up my 1 TB hard drive. That means deleting the entire drive and using it as a backup drive for storing miscellaneous and less frequently accessed files. I’m not worried about the new SSD failing, because I have Time Machine. I can always restore the entire OS from my Time Machine backup. So, I dumped everything on the 1 TB drive and emptied the Trash Can. I took awhile, but now I have all that real estate for storage.
Samsung is now shipping the 15.36 TB SSD based on a 12Gb/s Serial Attached SCSI (SAS) interface. It’s will not be cheap. Samsung has not revealed the price yet.
In addition, Samsung will also release different versions at 7.68TB, 3.84TB, 1.92TB, 960GB, and 480GB. The speeds of this new SSD are going to be other worldly with sequential read and write speeds of up to 1,200 mbps.
Six months ago, I installed a SSD drive on my Mac Mini. The speed of the SSD drive was a welcome addition. System boot up was cut in half. Access to applications were almost instant. It was all fun until I started having problems with SSD drive. Constant hangs and constant reboots for several weeks took its toll. Thanks to Time Machine, I’m now restoring my entire drive back to my original hard drive which is not in use. The restore process should take a couple of hours or so. I expect my computer to be slower with the hard drive, but it should be more stable than my current SSD.
If you are in the market for a 2011 MacBook Air, you better check the SSD (solid state devices) that comes with the laptop. Apple ships both Samsung and Toshiba SSDs. Why is Apple using two suppliers? It’s probably due to shortage of SSDs. What’s the difference between Samsung and Toshiba SSD? The difference is in speed, not by a whole lot, but it’s something to consider when making a big purchase. You want the best bang for your buck. Here the details about the speed difference from Engadget:
The 128GB Samsung SSD in his 11-inch Air was able to achieve 246 MB/s write and 264 MB/s read speeds. When he switched to the 13-inch model, however, speeds dropped to 156 MB/s and 208 MB/s, respectively, using that notebook’s 128GB Toshiba SSD.
We compared speeds on two generations of 13-inch models, and confirmed Jonathan’s findings.
During our tests, the 256GB Samsung drive in our older model achieved 214 MB/s write and 251 MB/s read speeds, while the 128GB Toshiba drive in the new MacBook Air scored 184 MB/s and 203 MB/s during write and read tests, respectively.
Samsung SSD is definitely the way to go. How can you tell if you have the Samsung or Toshiba SSD? From ZDNet:
You can check which SSD module you have by going to About this Mac > More info… > System Report… (the new name for System Profiler) and clicking on Hardware > Serial-ATA in the left pane. If the enter for APPLE SSD is followed by SM, you have the Samsung, if it’s followed by TS you have the Toshiba module.
It might be preferable to buy a 2011 MacBook Air directly from an Apple Store, rather than buying it online. At the very least, you can check the SSD before making a purchase.
According to Ars Technica, Apple is now shipping MacBook Airs with SSDs that are made by Samsung instead of the original SSDs supplied by Toshiba. The switch seems to increase writing and reading performance speeds, on the 2010 MacBook Airs by 20-25 percent, according to tests performed by AnandTech.
I happen to have the MacBook Air, purchased around early December 2010. I wanted to know if I have the original Toshiba SSD or the new Samsung SSD. Before I digging in, I had a feeling that I had the older SSD. I have been very happy with my MacBook Air since I purchased it. But, knowing if I had the faster SSD would be nice.
Go to the System Profiler by accessing the Apple menu and then clicking About this Mac. Go to the section called Serial-ATA, you will see the Model number of your SSD device. Mine says: APPLE SSD TS128C. That means I have the older Toshiba.
It would have been nice to have the faster Samsung SSD, but I have been very happy with my new MacBook Air’s performance. No complaints here. So the question is, how do I get the new SSDs? Is it even possible to swap devices?
