I absolutely love these cards. While I don't notice a speed in writing and recording, sandisk in general makes great reliable memory cards.

Excellent Speed, Good Built Quality Writing speed is much much faster even in USB2.0, when compared with other USB3.0 pen drives... and if u r connecting it on USB3.0 port, enjoy the speed ! Go for it !!!!

Performance is brilliant. Form factor is brilliant. There's no question about the built quality, and reliability, though it falls under the marketing numbers of up to 260MB/s Write and 240 MB/s Read.

Difficulty to justify USB 3.0 drive considering the price is over a consumer grade 120GB SSD; Marketing performance numbers higher than actual, Vague ‘Lifetime warranty’ Period.

I bought this sd card for my camcorder. This sd card holds hours of recording plus pictures. Straight out of the packet into the camcorder and up and running. Also you can directly plug it into the laptop and review whats on it within seconds.

There's a lot of USB 3.0 sticks but many don't have performance worth talking about. This and the high end Lexars do. The Sandisk is good value (these days) and a reliable brand. Be careful of clones on eBay. The only reason it's not 5/5 is the form factor.

If you need speed out of your USB, this is a great option. however, there are cheaper options out there that can do the same stuff

-its fast; -its rather sturdy

-its bulky; -price per gb is very high

When you first look at the Extreme PRO series you will raise an eyebrow and will start to wonder that exactly has been changed over the Extreme II series from SanDisk. Well, when we purely talk about peak performance, sure nothing much.

We were also lucky enough to get our hands on a second drive which we combined in RAID 0. We are happy to report that performance scaled well and the dual drive config provided exceptional results.

Not all solid-state drives are created equal. SSDs using cheaper NAND memory and controllers - value drives - focus on sequential speed as the headline-grabbing figures. Premium consumer drives exhibit similar out-of-the-box figures but, crucially, offer up much better long-term performance and...

The Sandisk Extreme Pro 480GB has certainly not disappointed. Sequential performance is excellent and, like many of the latest drives is pushing the SATA 3 interface to the absolute limit.

10 year warranty; IOPS is strong; sequential performance; incompressible and compressible data

It isn’t cheap by today’s market pricing.
