Samsung 850 Pro 512GB SSD Review

Final thoughts and the conclusion


User experience

A modern operating system such as Windows 8 rarely does one
thing at time; it processes hundreds of threads at once. Just take a look at
the processes and services that are running in task manager for an idea of how
much is going on, even with the PC idling at the desktop. When you start
running applications on top of this, the workload increases in line with the number
and type of applications you are running. It’s also fair to say that many of
these processes are already loaded into system RAM, but many are also loaded into
and unloaded from RAM to the system drive as and when they are required.

If we look at the 4 basic requirements for a really fast
SSD, they are as follows.

  • Small file threaded performance needs to be high.
  • Small random file performance needs to be high.
  • Sequential read and write speeds need to be high.
  • Fast access times. 

The Samsung 850 Pro SSD series SSD has all of these attributes
in abundance, and feels very snappy in use as a system drive.

Stability

I have only had the Samsung 850 Pro SSD series SSD for a few
weeks, so it’s not possible to comment on the drive’s long term reliability
yet, but will see what happens over the next twelve months as the Samsung 850
Pro undergoes its long term testing.

The Samsung 850 Pro SSD is as “plug n play” as it gets.
There are no special tweaks needed other than simply making sure that AHCI SATA
mode is enabled in the system UEFI (BIOS), and installing the latest Intel RST
SATA drivers, if you want to get the best performance and compatibility out of
this SSD.

Conclusion:


Let us summarise the most important positive and negative
points below:

Positive:

  • 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 performance is excellent.
  • TRIM support under Windows 7 and Windows 8.
  • Completely silent operation.
  • Fast operating system start-up and shutdown times.
  • Very fast in ‘real world scenarios’.
  • Low power consumption.
  • 10 year limited warranty (82.8GB writes per day).

Negative:

  • Nothing to mention.

To sum up, this is what I
would say:

As an operating system drive, the Samsung 850 Pro 512GB 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. Endurance is much improved over the current crop of planar MLC
NAND. Plus as added bonuses you also get a boost in NAND performance, and lower
power consumption.

Rapid mode is a nice inclusion, and does boost performance
in the real world. My only worry with the increased amount of system memory
made available for caching data (up to 4GB) is one of a system crash and data
loss. However, ‘Rapid mode’ proved to be very reliable and stable during the
testing period, and caused no problems whatsoever.

The Samsung 850 Pro should be on your shortlist of SSDs if
you intend to purchase an SSD in the not too distant future. The 850 Pro is
arguably the fastest SATA SSD currently available. Adding to that, 3D V-NAND is
outstanding, making the Samsung 850 Pro very hard to resist.

Price and availability

The Samsung 850 Pro 512GB SSD has been available for a
while, and I found the 850 Pro at OCUK
for £279.98 including VAT.

I also found the Samsung 850 Pro 512GB SSD at newegg
for $301.99.

The parting sentence is:

“The Samsung 850 Pro 512GB is an outstanding, high
performance, prosumer SSD, with a performance profile ideally suited to real
world computing”.

Rating system

The editor rating is based on the following key factors.
