Just wonder if u actually feel the difference in speed in daily task? I have the 2012 one, wonder how much difference the 2013 is.Download blackmagic disk speed test app for free
Here are my two machines:
Late 2013 13.3 rMBP (512G, 2.8, 16G)
Late 2012 13.3 rMBP (128G, 2.6, 8G)
Good speeds. Just a casual question what kind of endurance does this drive have or whats the p/e cycles.
Does it display this info in your SMART attributes? Like how much data written and p/e cycles. The sandisk 512gb flash i had on my early 2013 does not have these attributes perhaps you guys can check with smart utility.
Normally the bigger size SSD are faster, the difference isn't much but if you compare most 128gb models vs 256gb you see a decent increases.Yeah, I'm still scratching my head on why my 1TB seems to be faster than the others
Yea, the performance gap between the 128GB and 256GB is massive, but less so between the Samsung 256GB and 512GB (different story for the SanDisk 256GB though). The SM0256F gets 720/660MB/s and the SM0512F scores 760/720 MB/s in reads/writes respectively.Normally the bigger size SSD are faster, the difference isn't much but if you compare most 128gb models vs 256gb you see a decent increases.
Are you sure yours is a mid-2013 Air? As far as I know, the mid-2013 Airs only use SD0256F or SM0256F.Should a 512GB be faster than a 256GB? I recently got a mid-2013 MBA (I know this is the MBP forum) with a 256GB SSD, and it happens to be the Toshiba model rather than the Samsung model. I'm only getting speeds of 500 write / 600 read, which seems to be slower than the 700/700 speeds I've seen in reviews.
Both the MBA and the MBP use the same PCIe technology, right? Curious if I'm getting shafted to the tune of about 30% performance with the Toshiba SSD in my MBA.
Not to mention, the last round of MacBooks that had Toshiba SSDs had recalls due to high failure rate. http://www.geek.com/apple/apple-recall-macbook-air-at-risk-of-catastrophic-ssd-failure-1574292/
Thanks for the response. I'm sure I ordered a mid-2013 Air, but now that you mention it, I guess it's possible that Apple sent a different model. Since the mid-2013 looks identical to the old model, I may not have noticed. I'll have to double check when I get home from work.Are you sure yours is a mid-2013 Air? As far as I know, the mid-2013 Airs only use SD0256F or SM0256F.
The SD0256F gets around 700/550 MB/s and the SM0256F gets around 720/660 MB/s in reads/writes respectively.
Toshiba SSDs were used in the Ivy Bridge mid-2012 Airs. If yours is a mid-2012 Air, the speeds that you posted are normal as it's a SATA3-based SSD.
To confirm your Air's model, go to → About This Mac → More Info.
