Patriot EP Series 128GB Secure Digital Extended Capacity (SDXC) Flash Card Model PEF128GSXC10233

Pros: Nothing really.

Cons: Paid a lot of money for this because of the name, size and the stated speeds.

Unfortunately read/write speeds were extremely slow from the start, 5mb/s. But I just thought my USB card reader was being finiky with the new SDXC format.

Read speeds were then very slow in my Tegra 3 tablet for 6 months, CBR's took forever to load. But it still no errors or major problems, and mp3's ran fine.

Then 1 day the card was not visible, even after remounts and reboots. Attached the card to my USB reader and Windows instantly asked me to format, like the file system had disappeared, and all of the data with it. Luckily everything on it was just a copy from my main system.

Other Thoughts: Dealing with Patriot RMA support now. So far they've been nice and quick to respond. I'll see how the replacement goes.

Pros: Ok they replaced it with a working one, wasn't hard to do but I did have to wait a little bit.

Cons: the original broke after about a month

Other Thoughts: lets hope this one lasts longer!

Pros: Large size
Pretty quick when it works

Cons: Broke within a months use.

Pros: BIGG!! & FAST!!

Cons: None

Pros: Have not had any problems with the Card. I use it as aux storage on my ASUS Aspire 5253-BZ602 with ZERO problems. The chip has been plugged in and out of my computer many times and even in very rugged conditions! The read and write times seem faster than my other 16 and 32 gig SD chips but have not had the time to run a speed test.

Cons: Seriously I have not found a Con yet... It is yet to be seen how long it will last... One thought for Patriot now.... HOW about a 256 GIG!

Other Thoughts: It would be nice that AFTER a Format there would be exactly 128 GIG, but the chip only has about 120 GIG with the rest being taken up by its system...

Pros: The CrystalDiskMark3 numbers I posted in my original review were for the 32GB version by accident. The 128GB numbers are better:
65.95 MB/sec read and 41.91 MB/sec write with my USB3 Kingston reader
66.19 MB/sec read and 41.52 MB/sec write with my USB3 SIIG reader

which are even better than the manufacturers specifications and a few MB/sec faster than the 32GB.

Cons: Wish there was some blank space on the label so I could write on it.

Pros: Ran a couple quick passes of CrystalDiskMark 3 and got:
57.38 MB/sec read and 39.72 MB/sec write with my USB3 Kingston reader
60.31 MB/sec read and 39.84 MB/sec write with my USB3 SIIG reader

which exceeds the manufacturer's specifications.

Cons: Wish there was some blank space on the label so I could write on it.
