Actually it depends a bit per region (VAT) + the OEM version are cheaper (just the SSD), the retail kits with install kit etc are up-to 20~25 bucks more expensive on top of that. But I'll switch the prices to the most simple SKUs.

Nice review, however at the last page it is stated that the endurance of this ssd is 300TBW. According to samsung this is only true for the 850pro version. The evo has an endurance of 150TBW:
"Samsung guarantees the 2TB 850 PRO for 10 years or 300 terabytes written (TBW), and the 2TB 850 EVO for five years or 150 TBW."

Correct, the 2TB - 850 Pro is rated 300TB/10 years warranty and the EVO 150TB with 5 years warranty. I've changed the last page to reflect that better.

Hilbert....Great Review (as always) but I think the pricing per GB needs to be updated....I just picked up a 500gb 850EVO for £120 which works out at around 169 euro's and Amazon's recent 'steady' price has been £135 or 190 euros....working out at 38p per GB.

I know its nothing much...but the price of SSD are coming down and it would be better to give people a more accurate cost per GB....

These days, though, you can buy 1TB, 7200 rpm drives with 3-5-year factory warranties, for $50-$60. (Retail drives, not OEM.) That's really the metric to use. That is 5-6 cents per gig... Even at your price that's still ~600% more per gig/drive...('course I'm using dollars here and may be a bit off your numbers.)

I have an EVO 850 250GB drive I use at home as a boot drive (Windows & utilities & drivers)--love it, it's great. Everything HH says about them is true, as I know you will agree. One of my other drives is like the above-described drive, and in normal AHCI service (not RAID 0) the drive will transfer up to 130MB/s--RAID 0 would peak @ ~2x that performance, so I think for many the question is: do I want to buy a 2TB drive for ~$800 that will max out @ ~500MB/s, or twin 1TB 7200 rpm drives in RAID 0 for $120 that max out at half the max transfer speed of the SSD...?

I think SSDs have a ways to go before they can be considered "mainstream"...but that time might not be all that far off... I can foresee WD madly scrambling to get into the SSD business; but I think it will be awhile before the storage capacity and prices equal those available in mechanical platter drives. But in ten years...? Difficult to foresee any mechanical drives being sold, frankly--barring a couple of substantial breakthroughs in platter-drive manufacturing that of course have yet to materialize.

Could we get some editing going on please? Confusing & misspelled info on which drives uses what controller (maybe this could be in the specs table?), conflicting info on the TBW between page 1 and the specs table, page 2 calls this the 500GB review, etc etc.

I'll come back in a day or two, hopefully the article will be coherent by then.
