It's fast, but...


I bought two of these to backup important financial and legal data. Halfway through copying the data, both drives went into a funky read only/write protected mode. I ran the unlock utility from the patriot memory website, but it only temporarily unlocked the drives.

When I formatted them out again with NTFS and started recopying the data the same thing happened again as I copying the data back onto the drives. This time the unlock utility would not unlock the drives and I ended up with drives with half my data that was unable to be erased.

I was going to RMA the drives, but I had second thoughts after realizing that the drives had important financial data on them. So I ended up smashing the drives with a sledge hammer and throwing them in the trash.

Now I am out of a bunch of my time and some serious $$$.

Other Thoughts:

I've used many patriot memory products in the past including the 128GB version of these drives with absolutely no problems. I'm guessing something has changed in these 256GB drives. Perhaps they have a new chipset/firmware.

I find it a bit silly that these drives have a write protection feature that can kick in with half your data on them. I find it even worse that the unlock utility doesn't always work.

Bottom line...Buy something else if you have data that you actually care about.
