This (240GB) was absolutely error free in HP 8200 Elite (Q67 chipset) with Windows 7 x64. Performance is consistent with what was advertised and what other sites have tested - and it hasn't slowed down in the few months I've had (unlike the 840/840 Evos). Windows partially goes through the checkbox animation and then jumps straight to the login screen. Nice! Update: Desktop still works great 8 or 9 months later, hasn't slowed down noticeably or anything. No stability issues. I just bought 480GB for my zbook 14g1. This also works like a charm so far. If I need more SSDs, it will now be Extreme Pro or Ultra II. Update: I've since tried one of the drives in a Zbook 14 g2 and a Lenovo t440s. Works like clockwork all around and doesn't crash under load unlike other drives. Throw a 200GB transfer at them and Windows (resmon) shows 25% usage at max gigabit connection usage. (Unlike other drives that advertise similarly high speeds but suffer if you give them a huge file transfer and don't give them time to TRIM afterwards.) I'll definitely buy another one of these when I need one.
