When we took at look at SanDisk's Extreme II series of solid state drives in June of last year, we began our article by noting, "odds are, if you've bought anything that uses flash memory in the last 20 years or so, you already own a small piece of SanDisk technology.

Strong Performance; Excellent Warranty

Somewhat Pricier Than Some Competing Drives

It is not often that we review two separate SSDs within the same report, however this is a rather unique opportunity. Back in 2016, Western Digital acquired SanDisk in one of the largest flash memory purchases ever; a very rare occasion for a company to actually purchase a flash manufacturer.

The pricing is what you'd expect for an SSD, but you're getting the form factor and usable space of 119GB. The casing is slimmer and uses capless design. The built quality and aluminum casing supports the premium pricing.

Performance; Performance~Storage; Built Quality and form factor

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

Earlier this year SanDisk launched yet another massive portable flash drive with the SanDisk Extreme Pro USB 3.1. The latest version comes with capacities as high as 256GB (there is also a 128GB version available).

SanDisk Extreme Pro CFast 2.0 CFast 2.0 memory cards were specifically developed for next-generation professional video applications as 2K video was common and full-frame 4K video was gaining traction among high-end production companies and individual enthusiasts.

SanDisk's Extreme PRO is a great choice for the gamer, enthusiast or media professional looking for an SSD that delivers consistent, pro-level performance and long term endurance.

Available in 240GB; 480GB and 960GB capacities; Marvell 88SS9187 controller; nCache Pro Technology; Excellent sequential read and write speeds; Good random read and write performance; Performs equally well with compressible and incompressible data; Consistent performance; even after intensive usage,...

Does not support hardware based encryption; Pricey

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.

SanDisk definitely have a winner on their hands with their Extreme PRO SSD thanks to its read and write speeds

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...

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.
