Data Migration requires the original drive to be "C:" or in it's original location; an extra cost SATA-USB disk adapter was required and I used a Kingwin EZ-CONNECT SuperSpeed USB 3.0 USI-2535SIU3 for copying to the SSD. Because there was a error at the end of the data migration, I needed to to perform a Windows 7 recovery with an existing Windows 7 Home Premium 64-bit OEM DVD. If you need to perform a recovery, you will need to purchase or borrow the correct version of a Windows DVD (64-bit in my case). If you need to re-install Windows (perform a complete or destructive re-installation), you need to purchase a "Genuine" DVD or or have the original DVD that is licensed to your PC; first, try to save critical data that will be wiped out.
The "Magician" software was not very clear to understand.
a. Run this after you migrate the data to the SSD.
b. AHCI mode (in the BIOS) is recommended but I had to restore the default compatibility mode. ACHI mode had failed on my laptop, requiring another Windows recovery.
c. RAPID mode (disk caching in memory) ate up a lot of memory (63% or higher used of the 4 GB total installed - 36% memory used after a reboot), so I disabled it. Yes, everything ran very fast under RAPID mode but I’ve seen issues with this kind of software in a different operating system. I felt that the laptop ran “fast enough” without that software.
d. I used the default “over provisioning” because I wanted the capability to replace a bad sector with that recovery space. Lose some SSD disk space now for better recovery later.
I had repaired the laptop for someone else and they are extremely happy with the results. I had bought the $95 850 PRO because of the 3D memory and a 10 year warranty. I was a little concerned that only 50 GB space remained. If I had to do it over, I probably would have chosen a larger capacity drive (256 BG works well in my home PC). Some other SSD’s have that capacity at the price of the 128 GB Samsung. Those other SSD’s may not have a software package; you would want, at a minimum, disk cloning software; some SSD’s may offer a version of Acronis to download - I previously bought a copy of Acronis, which had extremely fast transfer rates.
This product will make your PC bootup faster and make it perform faster once running. Applications open more quickly. File saves occur quickly and quietly. Everything is just snappier. If you're outputting your work and it has to go through some sort of conversion process which involves starting up some other app or background utility, this will all happen considerably faster.
My only complaints are in regard to the installation. The instructions consist of a sequence of drawings / diagrams with no wording. Multi-language compatible YES, explicit and clear NO. If you have never installed an SSD before, you will want to know beforehand that there are a couple of additional items you may need.
1. 2.5" Sata to USB adapter (often over $20.00)
2. 3.5" to 2.5" HDD/SSD drive bay adapter with mounting screws.
The USB adapter cable allows you to connect the SSD to your computer and clone your existing HDD onto the new SSD before you install it into your system. This is more necessary if you have a laptop with only one HDD drive bay. If you have a desktop PC, you may go ahead and install the blank SSD into the case internally or at least connect it to the power supply and motherboard like your other hard-drives and then use the Samsung Data Migration software to clone your C: drive / OS boot drive onto the SSD.
Your PC case may have built-in 2.5" drive bays or it may have included a 3.5" to 2.5" adapter, if you purchased it separately. You'll want to check that out before buying and determine if you need to buy an adapter to go along with the SSD or you may also use sticky-back velcro tape to mount it inside the case. The Samsung 850 Pro 128GB is very light-weight..
As close to the same time as possible, I opened up every program in the microsoft office suite, plus chrome and MATLAB (a big program that takes several moments to start on quick computers and over a minute+ on slower computers) and the results were: office programs opened the instant I clicked them, chrome took a second or less (though I have very slow internet, so it's hard to tell when chrome has loaded vs google.com has loaded. Chrome might be instant as well, I just have a slow connection and can't tell), and matlab took about 6 seconds. I am very VERY happy with this. I can't wait to buy another one (and bigger than the 128GB one that I bought for this laptop) for my i7 desktop.
Top reviews from other countries
is that it all worked okay, with a minor hoop to jump through with cloning from my HDD to the SSD. Also, turning on AHCI
gave me a performance boost, but you have to enable it properly in Win 7 before turning it on in the BIOS.
Installation:
When I read the installation instructions leaflet (all diagrams, no text), it indicates you
should connect your SSD via a USB-to-SATA adapter (not supplied) and then perform the
data migration (cloning). In fact, the USB adapter isn't required - I installed the drive
internally in my PC and the cloning software worked okay (see below).
On the supplied CD there are two pieces of software - Data Migration and Magician software.
I ran the exe in the top directory of the CD drive and it gave me option to install both
pieces of software at once. I'm not sure if I missed something, but it only seemed to install
the Magician software. A quick navigate to the Data Migration directory and running
an exe I found there quickly remedied that issue.
Cloning:
The Data Migration software is very simple and only gives you the option to migrate
all the partitions from your existing drive to the SSD and not a subset. I have
a 500Gb drive on which I had a C: 120Gb Win7 OS partition, that I wanted to migrate, but also
a D: partition that I didn't. However, all you get is a "Start" button. So I exited
the Data Migration software, removed the D: drive letter assignment (via diskmgmt.msc),
and re-run the Data Migration. This time, it only showed the C: drive on my source disk
as a migration to the SSD, and I went ahead and clicked Start. The migration took about 15 mins or so,
with my source partition being about half full, after which I re-added the D: drive letter assignment.
Note that the Data Migration software gives a scary message saying that it will not migrate any open
files, leaving you wondering whether the OS files - many of which are presumably open -
will ever get migrated. However, it all seemed to work okay when I finally booted the SSD.
Rebooting with the SSD:
After the cloning had finished, I rebooted and this is where things went wrong for me
(temporarily). I had run up the Magician software just before cloning, and it had mentioned
in its home screen (where it shows the drive status etc) that turning on AHCI mode
improves performance. I made the mistake of rebooting into the BIOS, changing the primary
boot device to be the SSD (fine) but also turning on the AHCI mode at the same time (mistake).
Rebooting gave a Windows boot error with the option of ""Launch Repair" or "Start Windows Normally".
I didn't know what was going on at this point - whether it was the cloning gone wrong or what.
I didn't realise at the time that, for Win 7 at least, you have to go through a procedure
to enable the AHCI driver first (see below). After resetting my system to disable AHCI and
rebooting, I still got the boot error but, upon choosing "Start Windows Normally" my system
came up (very speedily!). I don't know if I would have got that boot error regardless
of turning on AHCI.
Performance Testing and AHCI:
Well so far, after a day, it's okay and I'm writing this review using my Win 7 OS cloned onto the
SSD. Magician includes some some benchmarks that I ran and have given the results below (my system is
a Gigabyte Z77M with a Core i3 i3225). I tested with and without AHCI. Enabling AHCI in Win 7
(do this before changing it in the BIOS!) involves either installing an update from MS or, as I
chose, changing a registry entry, rebooting with AHCI disabled, then rebooting with AHCI enabled.
Rhese are the results I got with and without AHCI, and also setting 10% Over-Provisioning (OP) in Magician:
AHCI off, no OP:
Seq Read/Write (MB/s): 439 / 443
Random Read/Write (IOPS): 8972 / 27846
AHCI on, no OP:
Seq Read/Write (Mb/s): 541 / 515
Random Read/Write (IOPS): 57180 / 60880
AHCI on, OP 10%:
Seq Read/Write (Mb/s): 564 / 525
Random Read/Write (IOPS): 63129 / 60400
Results speak for themselves. However, there was a very minor degradation in the
seq write performance of my existing HDD (Seagate 7200.14 500Gb) when I turned on AHCI (100 -> 96):
AHCI off:
Seq Read/Write (Mb/s): 75 / 100
Random Read/Write (IOPS): 170 / 287
AHCI on:
Seq Read/Write (Mb/s): 77 / 96
Random Read/Write (IOPS): 314 / 290
I think I can live with that.
Final tip - I don't use Hibernation any more - don't need to as the ordinary system boot is so fast but, also, it can end up writing a large amount of data and therefore using up your Total Bytes Written just that little bit faster.
Overall, I'm pleased with the drive and software - I hope it lasts the distance!
L'un de mes soucis, c'est que lors de l'installation d'Ubuntu, j'avais choisi de partitionner /home en plus du /swap. Ce qui était la meilleure solution en 2010, mais plus maintenant. Même si j'archive régulièrement mes données personnelles sur un autre disque (le disque dur en prod n'est pas un espace de stockage!), les deux partitions étaient remplies à plus de 80 %, ce qui n'est jamais conseillé en termes de performance.
Donc, j'ai pris du 128 Go SSD dans la série pro. Pour le même prix, j'aurais pu avoir 256 Go dans la série non pro (carré gris), mais la longévité du disque m'a semblé bien plus importante que la place, puisque, je le répète, un disque dur en production sur un ordinateur n'est pas un espace de stockage. Ce qui me double tout de même la capacité, tout en m'assurant à peu près de ne pas commencer à baliser sur la pérennité de mon disque dans 5 ans (temps moyen pour un SSD).
Niveau montage, j'ai été particulièrement surprise de voir que mon SSD d'origine n'était pas caréné : juste une petite plaque de circuit avec des mémoires flash collées dessus, le tout monté sur un châssis de métal.
Pour monter le nouveau disque, c'est plutôt simple, mais il faut faire attention, les disques SSD étant très fin, ils sont tendance à passer sous la map de raccordement au la carte mère. Il faut alors retourner l'ordinateur (position normale au lieu de sur le dos pour accéder à la trappe!) pour que le disque s'insère bien droit. La vis de fixation étant courte, si ça patine dans le vide, c'est que le SSD n'est pas mappé, il faut retourner et recommencer.
Une fois le disque bien inséré, c'est très facile : aller sur le BIOS au démarrage, demander à booter sur la clé USB bootable qui permet d'installer Ubuntu. Choisir l'installation par défaut, sur une seule partition (le /home sera quand même protégé en cas de réinstallation de l'OS). Ensuite, avec une dock station, on a copié le contenu de l'ancien /home du vieux disque sur le nouveau et c'est parti pour de longues années d'accès disque ultra rapide et de grande sobriété énergétique!

Research on the interweb shows that freezing is a common problem with ssd hard drives (not just Samsung ssd) and there are many suggestions for correction usually involving editing the registry (google "ssd freeze" and you will find them) - I have not tried these because they did not make sense. The problem, I think, is to do with the firmware and the way it interacts with AHCI, and the change from AHCI to IDE in the BIOS appears to have done the trick. In theory, you sacrifice a bit of speed - I have not noticed any difference, so you don't lose much.
Also note that you will get a new power plan in "Control Panel\All Control Panel Items\Power Options" , mine is called "Samsung High Performance" which is set to switch the display off after 15 minutes of no activity and replaced my own power plan - took me some time to figure out why my screen kept switching off when I went for a coffee. I got into the habit of checking the power plan immediately after booting up and that did not work!! Then I noticed the Samsung High Performance plan which does not appear straight away after boot up, changed the setting and now OK.
You also get 2 pieces of software
1 - Data Migration - for transferring the data on a HDD to a Samsung (only) SSD
If you are transferring from a smaller HDD to a larger SSD - no problem, just go for it.
If you are transferring from a larger HDD to a smaller SSD - you can choose not to transfer music, video and photos, if the data to transfer is too big then you will have to delete "stuff" off the HDD - deleting system restore files will get rid of a big chunk and then its onto deleting applications etc. which does not get rid of as much as you think.
2 - Samsung Magician - this monitors your Samsung SSD and other drives and also enables you to make a few changes to settings
UPDATE
Re-installed SATA 3 drivers with latest version and everything is fine. Award 5 stars.
The migration software was incredibly straighforward, I did not have to worry about clearing data as the OS partiton was 'only' 70GB. The actual time to migrate the data was 15 minutes (barely time for the coffee I made). A quick reboot with a trip into the bios to switch the boot drive and the ssd booted into windows and had switched places with the previous C drive which was now labelled H, the other partitions had retained their prior letters. I opened disk management and removed the drive letter from from H and the Dell Recovery partition which had been given the letter I.
After some tweaks to the ssd configuration for overprovisioning and maximum life and it was ready for use. Seagate speeds were 44 MB/s read 64 MB/s write, the ssd are 527 MB/s read 462 MB/s write which is 8 times faster. Boot time has reduced from 120secs to 35 but more importantly Sleep is much faster. Resuming from sleep is 7 seconds and entering Sleep is 3 seconds, in fact the first time I put it to sleep I thought it had crashed it was so fast!
The only non-standard config I made was that the Samsung Magician software disables system restore to reduce ssd writes, but as I still had the seagate hdd installed I re-enabled it on the ssd but set it to 1GB on the ssd, one of the other partitions has a modified restore size of 70GB so that is used instead. With some surprise it still had the previous restore points from before I installed the ssd.
Overall this is an amazing ssd and I am very happy with it.
