I had my original 15in CTO machine replaced due to screen ghosting and luckily the replacement came with a Samsung display. While checking to make sure the machine was configured correctly I noticed the disk was an "APPLE SSD SD512E" rather than a SM512E like my original model. Benchmark wise it's a tad slower on the write side (10-20MB/s) but a tad faster on the read side. I know the SM512E is basically a Samsung 830, does anyone have an idea what the SD512E is? It benchmarks like a SanDisk Extreme SSD. No real complaints so far but I find it odd that no one else has posted about this. I believe my machine was built during week 48 as it shipped 12/6 and arrived 12/7. Anyway, something to keep an eye out for. Are SanDisk SSDs better/worse than the alternative? I know benchmarks aren't everything and I don't notice a difference in day to to day use but Apple must really be driving away from Samsung (granted the SanDisk SSD has a Samsung chip on it). Pics attached for those who are curious.
