Excellent SSD

Got these installed a few days ago on my Linux-PC in Raid 0. Amazing performance. Boot up time is superb. Everything works instantly.
Very impressed with service and an amazingly fast delivery, being next day before 1pm. Well done everyone.


Incredible Upgrade

This SSD is absolutely fantastic in terms of everything you could want - performance, reliability, size and price. I bought this SSD for just under


Excellent SSD

I ordered two of these on Saturday and they turned up this morning (Monday). Great service from Overclockers, thanks !
Got them running on my Linux machine and they are much faster than my other windows 7 system (that has Samsung 830).
Excellent performers.


Superb Product!!

It has been a while since I bought something from OverClockers, but I just bought this Samsung SSD and it is brilliant, it has supercharged my laptop which needed this badly, so I cannot recommend it enough, great software to, to enhance what you already have.
The service from OC was 1st Class, ordered 4:30pm and it arrived the next day super quick delivery and very well packaged, glad I came back to you guys :-)



Just Wow

amazingly fast. also comes with amazing software for tweaks. Best SSD for price


Decent speedy drive

Probably about the best SSD out there bang-for-buck. Decent head of speed (but then again most of the latest SSD's are pretty much hitting the buffer on SATA3), coupled with Samsung reliability. Though the data migration software Samsung supply is not bullet proof, as it managed to mess up the MBR on both the source and target disk during the cloning process (easily solved though by doing a Windows repair on the new SSD when installed as the boot drive).

All told a great buy.


Super fast Samsung SSD

I have upgraded from a 5400rpm hard drive in my old PC to this SSD and what a difference it makes! Loading screens are super fast and my boot time is hugely improved. Windows 8.1, a few games and Office fit easily onto the drive as it is plenty big enough, I still have 193gb remaining. But I do recommend getting a large HDD as if you store everything on the SSD you will fill it sooner or later. This drive also looks great in my HAF-X with its slightly shiny black finish.

Amazing speed, great looks, must buy for a mid-end system, 5 stars!



Brilliant drive, replaced a 830 and it's noticeably quicker booting into Windows 8.1.

Samsung's software that comes with the drive is the best yet too allowing you to keep an eye on performance and allowing you to make any tweaks needed.



Starts and shuts down windows 7 very quickly and in general loads games really quick very impressed!


Fantastic Hard Drive

I recently purchased this SSD and install of windows was 10 minutes or so long and windows boots up within seconds. Good job my case had a caddy for 2.5" drives otherwise i'd have it dangling down, so dont forget one :)


Great SSD, has mild software issues

I upgraded to this after having a great year with my old 128Gb 830 series (now moved to a laptop).
Great speeds, only flaw is the benchmark software from Samsung (Samsung Magician) doesn't shows the wrong speeds (current and not average transfer rate which causes it to spike). One last bad thing about the software is that there is a bug. I have notified Samsung about this, it can wake your computer up while on sleep mode - If this is happening to you, Samsung's response to me was to close the software when not using it as it does not need to be open at all times as long as your OS has TRIM support (Windows 7+) Really not too bothered with that but Samsung could do a lot better as their software is usually brilliant.
The rest of the Magician software is great, being able to optimise your OS to adapt to the SSD and enable 'RAPID (Real Time Acceleration Processing of I/O Data) Mode which enhances the SSD to improve overall system performance.

This SSD is phenomenal. From my 830 series to this isn't too much of a big jump once in the OS, but a mad increase in boot time (Was ~11, is now ~6 seconds with an AMD 8350 @ 4.33GHz, 16Gb RAM @ 1866Mhz.) The Windows 8 loading screen is literally less than a second.

Great bit of kit, highly recommend to anyone looking for an SSD with high read AND write speeds. 4 stars due to software issues. If I were basing the SSD without the software, would give 5 stars.


Fast drive!

Great shipping as always with OcUK, used the Samsung clone tool, cloned me Dell 7520 laptop fresh W8 OS over in 30mins, booted up and all was perfect.

Very please as it has dropped some weight and heat all good in the laptop world
