Here is another one, same price and BO option available. Samsung MZ 7GE9600 960GB 2 5" 6Gbps Solid State Drive SSD | eBay $350.
Got on a deal in the past, just pass it along to another Forum member since I'm not going to use it.
I saw the SV843 @ $300 as a great deal. I'd be much less interested in this drive at that same price, primarily due to the more limited endurance rating (the SV843 is rated at 1.6 Random full drive writes/day vs 0.3 RDWD for the PM853T).
Of course at the $240/each that @Patriot scored them for its very hard not to call them a steal.

Well, I got a pair of PM853T's at 240ea and a pair of SV843s at 250ea so... I have set the bar high for low price expectations.
Also... SM843T is 1.8 wrpd SV is 3.6 http://www.samsung.com/us/business/oem-solutions/pdfs/SM843TSV843-ProdOverview-2014.pdf
A high bar indeed! As for the dufference in our view of endurance - I only quote the 4k Random wpd numbers because it is more real-world. Very few applications do continuous linear large block writes.
In the end it doesn't matter much as the relative difference between the two drives remains.

That is random, sequential is 11 and 22 WPD respectively. Looking at a difference capacity?
But yes, TLC vs MLC even on VNAND. I am going to put the TLC to use in laptops and other low write applications and use the MLC in my workstation.
Fair play to that - but in this case the drive in question is PM853T (not SM843T). See here: http://www.samsung.com/global/business/semiconductor/file/media/PM853T.pdf. 0.3 Randon WPD, Sequential 1.6 WPD.
Yea the 853T certainly doesn't have the endurance that either the SV843 or SM843T have. The SV843 is head and shoulders above both in that regard. The SM843T is a major step up from the 853T still. It all comes back to, I wish I didn't miss that SV843 deal, lol. Now it just feels wrong to purchase the 853T for the same money.
I have not seen any SV843s for anything close to that price... you will have better luck with the SM843Ts for a lower price than the SV843s... That said 0.3 WPD on a 960GB drive is still a shedload of writes.
Edit! for clarity of thread.
Since there seems to be some confusion on the endurance of these drives...
Samsung's naming convention is probably partly to blame.
PM853T (TLC Vnand)
RWPD 5yrs*365*0.3*0.960 =525.6 TB
SWPD 5yrs*365*1.6*0.960=2803.2 TB
SM843T MLC VNAND
RWPD 5yrs*365*1.8*0.960 3153.6 TB
SWPD 5yrs*365*11*0.960 19272 TB
SV843 MLC VNAND
RWPD 5yrs*365*3.6*0.960 = 6307.2 TB
SWPD 5yrs*365*22*0.960 =38544 TB
For read workloads they should all fairly equal performance.
PM853T is faster than the SM843T on writes but slower than the SV843.
410/360/430 MB/s respectively.
Now... how much do you write to your drives... My 6yr old laptop... not much. 1800GB written to that 160GB X25m.
I don't think I have written more than 10TB to any of the SSDs I have used in my desktops over their used lifespans. And drives typically outlast their ratings. While the gap is huge between these drives... That is still more writes than you would probably do for most workloads.

Best I've seen (and got) for SV843 was here where a few of us split 10 drives @ $300 BO: https://forums.servethehome.com/index.php?threads/samsung-960gb-sv843-350-obo.5636/. Some have reported scoring better prices.
