Final thoughts and the conclusion
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.
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. What
I can say is that during the testing period, the Samsung 850 Pro 1000GB has
been 100% stable and has caused no problems whatsoever.
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
Let us summarise the most important positive and negative
- 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
- 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 (40GB writes per day).
- Nothing to mention.
To sum up, this is what I
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. 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
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, even although the new version of Magician (4.4) was a beta, it
proved to be very reliable and stable.
You should keep in mind that the Samsung 850 Pro SSD I have
tested in this article is an early sample. So between now and the 850 Pro’s
official launch, there is still time for Samsung to tweak the firmware and get
even more performance from this series of SSDs. As it stands, the Samsung 850
Pro series of SSDs should certainly be on your shortlist, if you are intending
to buy a Prosumer SSD in the near future.
Improving on the very successful 840 Pro series of SSDs was
always going to be a difficult task for Samsung. With the new 850 Pro however,
Samsung appears to have succeeded in this task.

The parting sentence is:
“The Samsung 850 Pro 1000GB is an outstanding, high
performance, prosumer SSD, with a performance profile ideally suited to real
