Uh yeah I got a replacement. Which I sold off, pronto.
Got 2 of the new 6G 240GB with the Toshiba toggle NAND and SandForce 2282.
1 Worked perfectly. The other one was hosed. I RMA'd it, they replaced it with a unit that works fine. No problems since then.
Except... I paid out a buncha cash for 2 new SSDs, the replacement they sent me was not new (according to SMART readings, it had been powered on for 55 days of continuous use before they shipped it out to me). Kinda ... b-llsh-t, but whatever, they both work extremely well. 484/write, 526/read, when RAID0'd & just slotted into the optical drive bays of a MacPro 5,1. Fastest speed I've ever had off dual SSDs on native Mac Pro controller.
OWC as an entire company is kinda hit and miss for me personally. I've purchased 10 of everything and had no problems, and I've purchased 1 thing, that goes back 3 times and never works right until they finally send a new unit after wasting a lot of my time (and money on return postage, not to mention credit-card holds if you demand they cross-ship immediately).
Edit- To be fair to 'em, I like OWC. Having purchased stuff from 'em since back in the late 90s, my personal experience has been-
85% - Very positive.
15% - WTF, are you kidding me with this ******?
