ORIGINAL REVIEW: Your warranty on this SSD is THREE years, parts & labor. Not FIVE like it says here. And never mind the box says "5 Year Limited Warranty" either.
Because when I looked up the model code stated right on that same box at the Samsung website (MZ-76P256BW) what I got back, under the warranty statement, was "Warranty Information for MZ-76P256BW - Parts : 36 months, Labor : 36 months."
That's just raw. Samsung has always been the go-to for top-shelf quality. What gives with this kind of maneuver?
The prior model, the 850 Pro, had a warranty period of 10 years, parts & labor. The shift from 10 years to (supposed) 5 years cast enough of a dark shadow on the product. Now this.
I say let's hope they start selling it at Bed, Bath & Beyond. They'll take anything back for store credit.
I used crystaldiskmark to benchmark drive performance. It tests with and without command queuing. Since all current operating systems I use (Windows 7 and later, Linux and Mac) all enable command queuing by default I'll focus on those results.
The drive does great with sequential reads/writes. I got reads of about 558MB/s and writes of about 512MB/s. Most SSD drives do fairly well on sequential read/write operations. With this drive the difference is only about 10% for queued vs unqueued.
This 860 PRO drive did better than many other drives with random reads at about 300MB/s and writes at about 207MB/s. Unqueued reads were about 36MB/S (almost 1/10th the queued rate!) and writes were about 65MB/s (about 1/3 the queued rate). Command queuing makes a big difference with random access and makes this drive stand out for this use.
The 2.5in SATA form factor works well with the Dell 2.5in to 3.5in adapters that fit into the existing drive caddies making 3.5in drive replacement a breeze.
An important factor for me and my clients is reliability. SSD's have come a long way since they were introduced some years ago. The Samsung Pro series has better reliability and higher write specs than their EVO models. They also have slightly larger sizes in powers of 2 rather rounded down to the nearest decimal value.
In conclusion, this Samsung 860 SSD is one of the faster ones I've used, especially on random reads/writes with queuing enabled. This drive was perfect to upgrade my client's system. The old mechanical drive is now retired and their previously fairly fast tower just flies now! With this sort of result I love these drives for upgrades. Definitely 5 stars.
