As an operating system drive, the Samsung 850 Pro 1000GB SSD is pretty hard to fault. Performance is outstanding and the SSD proved to be very stable during the testing period. The new 3D V-NAND is a huge step in the right direction in my opinion.

Silky smooth operation as a system drive; Outstanding sequential reading and writing performance; even at very low queue depths; Outstanding 4K random writing performance; at low queue depths; Outstanding 4k random reading performance at very low; and very high queue depths; Sustainable writing...

Nothing to mention

Samsung recently introduced their 850 Pro SSDs, which are the first consumer-oriented SSDs based on 3D V-NAND. Do they allow Samsung to reclaim the performance crown?

Solid reliable SSD drive. I use it to replace an older and smaller, 500GB, Crucial M500 SSD drive. This 850 Pro drive is much faster to boot and run programs.

Product was easy to install worked fine for a little over a month and then just stopped working. No warning signs nothing and just would work wasn't able to boot up anymore.

Samsung's new 850 Pro line of SSDs are easily the fastest on the market at the time of publishing. They offer all the newest features in one single package. Samsung's 3D V-NANA, RAPID Mode, and the huge 150TBW make this drive stand out from the crown.

We've seen many solid state drives over the past few years, some memorable and some forgettable. But it's rather rare to see new technologies emerge that push the boundaries of performance, features, and even pricing.

Extensive software package; Data Migration; Great stock performance; Otherworldly performance with RAPID Mode enabled

Price premium

So far so good with my scheme for updating a very indifferent and slow laptop. 2 mins to install, just goes exactly where your HD went, in my case attaches to small caddy using same screws that HD used.

I've had this SSD for 3 days now, I put it in with a new z97 motherboard and i7 4790k. The performance boost I had from switching from my old hard drive to this was honestly insane, would recommend this drive to anyone.

In the past few weeks, we've seen a steady stream of new solid state drive releases, from the likes of Plextor, Crucial, and SanDisk. Our review of the Plextor M6M mSATA drive can be found here , and we covered Crucial's MX100 series here .

Strong Performance; High Endurance; Long Warranty

Somewhat Pricey; No Power Loss Protection

Samsung created a lovely product with the 850 Pro series of SSDs, they are remarkably fast in pretty much any and all tests from our benchmark suite. The drive is continuously in the top 5 of tested SSDs performance wise and to see performance that high with such consistency shows that the SSD is...
