Last week i bought a "Runcore 64GB 1.8" PATA ZIF Pro IV Solid State Drive SSD for Macbook Air - Rev A" to mydigitaldiscount. The last one that had resolve the ZIF issue. Ok now some users that bought these one have a new unresolved issue, sleep or hibernate HANG the notebook. It works flawlessly for normal operation, but if we close the lid or hibernate, it hangs the system 2/4 times. Apparently it cause an IOATA block error. Be careful if you plan to buy one of the Runcore rev.a disks it does not work as expected in the Macbook air Rev.A 1,6 GHZ.
