Quick observations after the first 48 hours with the RunCore 128GB-C in my Apple MBA rev A.
Update after a little over three weeks of daily use of 4-12 hours.
However, the installed drive performs as advertised. It's fast, and lives up to the claims. Xbench Disk Test = 125.69 (Sequential = 96.75, Random = 179.31) with all my apps also running at the same time.
It's definitely slower with time. Not loads slower, but it's there. I just ran Xbench five times to try and quantify it:
91.71 (Sequential = 63.94, Random = 162.09)
80.43 (Sequential = 62.41, Random = 113.09)
86.47 (Sequential = 75.50, Random = 100.55)
66.95 (Sequential = 45.82, Random = 124.26)
77.81 (Sequential = 49.41, Random = 184.42)
I can now run far more apps with a far more responsive MBA, it's really like a whole new computer. The difference is easy to see and feel. For example, I used to dread it just a little when I knew I had to launch an MS Office app that wasn't already open, because it could take 30-45 seconds or more to get to the document. I just tried opening an Excel spreadsheet from Mail... launching Excel the icon bounced twice and the spreadsheet was open and editable around 3-4 seconds after the double click.
I've run the drive to the 85% full mark for about a week, then to 95% full, and now back to 50% full for the benchmarks above. It's definitely a bit slower than the first couple days after I put it in. I just tried the click-on-a-spreadsheet test from Apple Mail where it had to open Excel, and it was open and editable in 8 seconds after 3-4 dock bounces, which is still wonderful compared to the stock drive but definitely slower than it was at first.
I haven't run it down to zero, but battery life does seem to be slightly longer, perhaps 10%. It's hard to measure exactly since it's not a controlled test but me using my MBA on-the-go at meetings and bluetooth tethering in taxicabs.
I've not done any tests, so this is subjective, but I think the battery is either the same as previous, or perhaps it lasts a little less than before. This is hard to tell without some kind of test.
Booting took longer at first. It was cured by resetting PRAM, now booting to desktop from turning it on is about 30 seconds.
Booting now is taking about 40 seconds. When the drive was nearly full, it was taking nearly 60 seconds but appears to have recovered.
No issues with re-using my old 80GB HDD in the RunCore USB enclosure, except that the case screws were so tiny it was difficult to assemble. However, it just required some patience.
I love reusing my old drive as a tiny external 80GB drive. It's slow, but it works.
No sleep issues. I bought from mydigitaldiscount and the firmware is 1819.
I sleep/wake with the lid probably 6-10 times per day without problems. It wakes up instantly and is far more usable than with the stock drive.
Overall, I still love this upgrade. It's lost a step, and I'm not sure if it's to do with nearly filling up the drive or it's unrelated. I'm still smiling when I use my old MBA overall.
