After reading favorable reports by others, I was delighted with (not only the speed of the device itself) but the prompt delivery from MemoryC clear across the pond! I was moving up from an Mtron 32GB SSD which performed very well in my Sony TXN15P and initially procured a RunCore 128GB. After a 6 months delay in delivery, it appears I received a faulty device. It would frequently (several times a day) stall and freeze with the drive light continuously on, sometimes recovering after 5-15 minutes, occasionally dying with a BSOD. The device has been returned.
The KingSpec has proven 100% reliable since installation. I'm running Windows 7 on a Lenovo U110 ultraportable with the defrag, prefetch, superprefetch tweaks applied as recommended in the OCZ forum for SSD's. Even without these all apps installed without a hitch, no stuttering or slowing. The difference between the 4200 RPM original Toshiba harddrive is phenomenal. What a joy!
