I/O Errors on SDHC Benchmark Test

I recently purchased a Patriot Memory LX Series 32GB Class 10 Micro SDHC from, this is the first time I've used a Patriot Memory card. Once I got it in the mail I tested it with ATTO Disk Benchmark Tool v2.47 using the settings in the screenshot provided (I used the settings matching another customer on

I've tried different card readers, with the same results, and only this new card gets these I/O comparison errors. Chkdsk showed no problems though. I got this card on a whim, and should've did more research from other sites, the newegg and seem to have poorer reviews it seems. Also read this card (or maybe all 32GB Class 10 SDHC) has problems with Android.

Do these errors mean anything serious? Based on these results, is this card prone to corruption and data loss?

I checked the Patriot 5yr warranty, is it worth it to RMA? I'd have to pay S&H to Patriot...

bump for help. I've tried google, but I can't find out how serious I/O errors are for SDHC. I've transferred a 1080 movie onto the sdhc, and it transferred/played on my PC without any problems I could notice.

OK, so essentially what you are seeing is one value written to a memory location and a different value retrieved from the same memory location. That's a recipe for trouble. I would definitely contact the manufacturer at this point, and ask them for further interpretation. They should at least be able to tell you if there is a serious problem with the card, without paying postage.
