Samsung 840 Pro 512GB SSD Review – Performance, Value, Battery Life and Untouchable IOPS

Our report on the Samsung 840 Pro SSD begins post take off from Pearson Int’l Airport in Toronto and on route to Seoul, South Korea.

Having had this SSD in our hands for some time, even the enormity of the Samsung 840 family release celebration cannot overshadow the performance of what just might be the hottest solid state drive to hit the streets to date. How does just under an extra hour laptop life and 100,000 IOPS grab you to start?

We won’t even try to explain the iron clad confidentiality agreements that have been in place in effort to keep the Samsung SSD 840 Series a complete secret up until now.  Even us few privy to the Seoul  experience have had to compile these reports without access to data sheets describing the new controller and memory in use.  Quite frankly, it is the first time I couldn’t dig this info up through a simple internet search.

THE SAMSUNG SSD 840 SERIES FAMILY

The Samsung SSD 840 family will consist of the 840 Pro, intended for the enthusiast/enterprise crowd,  as well as a consumer edition 840 for the consumer.  The difference between the two lies only in the memory where the 840 will rely on triple level cell (TLC), vice multi level cell (MLC) NAND flash memory, and the firmware for the Pro version has been optimized for performance. Our analysis today examines the Samsung 512GB 840 Pro SSD and it will be available soon enough at prices that, not only rivals that of other premium SSDs but also, puts Samsung in a position similar to Crucial/Micron where they have the ability to effectively move the price point of SSDs even lower than we are seeing them now.

840 PRO SPECIFICATIONS

To put it lightly, the specifications Samsung lists for the 840 Pro are enough to make just about any storage enthusiast drool.  The 840 Pro is a SATA 3 SSD, will be available in capacities of 64, 128, 256 and 512GB and is of a 2.5″ 7mm ultra slim form factor.  Performance is listed at 540MB/s read and 520MB/s write with random read IOPS at 100,000 (yes that’s one hundred thousand) and random write at 90,000 IOPS.  Prior to writing this, I had to get Samsung to confirm the power ratings three times before print as materials listed 0.042W idle and 0.068W active. Is that even possible?  Through use of their new controller and memory it is and they have validated this through laptop testing where they found the laptops battery power was extended by just under an hour, on average.  Samsung wraps things up with their five year limited warranty

840 PRO COMPONENTS

The exterior casing of the Samsung 840 Pro SSD is of typical Samsung design, 7 mm thick and is secured by four pentalobe type security screws. Once removed, access is given to a PCB with controller, cache and eight modules of memory on one side of the PCB.  The back of the PCB is void of any components.

Samsung proudly acknowledges that the new 840 Pro is 100% Samsung born and bred, with the heart of the machine being their new 3-core eight channel MDX controller (300MHz).  Just above the controller is Samsung’s 512kb DRAM cache memory with eight modules of Samsung’s new 21nm MLC DDR-2 toggle mode NAND (400Mbps), each with a capacity of 64GB.

Although the RAW capacity is advertised as 512GB, formatting leaves the end user with an available capacity of 477GB.  Included with the 840 Pro will be the updated version of Samsung Magician 4.0 software which will enable users to manually configure between 7 and 24 percent of their drive for over provisioning, depending on their needs.  The Magician also contains disk scan and error reporting for monitoring health status as well as SecureErase which completes in under a minute.

the CDM for Pro version looks very VERY promising. especially its 4k read write performance and access time, simply fantastic, great review!. only thing im hoping to see now is Data on drive test and it doesn`t look like SSDreview covers that portion of it as well as HD-Tune. I just wish to see from many aspect of the drive it`ll really help me make decision on purchasing SSDs.

looking forward to this comparing with SLC S301 and OCZ bigfoot, and intel 525.

sorry forgot to mention another thing, chances are I will not purchase 512gb drive at all, im not so sure about other people but cost is over double of 256gb drive, simply no point. imo with Trim in raid 0, double performance and same storage while at a cheaper value is the way to go.

any chance SSDreview will review 256gb of its drive?

You are on the case, the 256 drive should have been reviewed since it is the most common purchased due to the price/gb ratio!

Unfortunately, we review what we receive and, considering the very limited availability of samples to reviewers, we were ecstatic to receive this SSD and all that went with it. Stay tuned for the 250GB 840 review in the next day or so.

Awesome. Just as I expected.

My Samsung 830 have been reliable all this time with no faults or hiccups what so ever.

My laptops battery life increased a dramatic 30 minutes just by installing the 830. Now, I can expect even better results with the 840, of which I’m sure to buy.

How does it compare to an OCZ Vertex 4 with FW 1.5? Easy to say its at the top when you’re not comparing it with the latest and greatest from all of the vendors…

Fair game… This SSD was reviewed on release as was the OCZ. We have worked with the OCZ and it is a great drive, one of my favorites in fact. In a review and at the end of the day, all factors need to be examined and not a specific metric don’t you think? We can work on an updated comparison in the near future if you like.

Yea I think it’d be interesting to see it head 2 head with the Plextor M5s pro and the OCZ Vertex 4. Also, any news on the OCZ Vector yet? (You seemed to be the first to tip us off about the samsung 840) 🙂

imo this drive SHOULD be faster than both plextor m3p and m5p, vertex 4 doesnt even come close btw.. that low QD1 read.. OCZ will have to bring out it’s bigfoot drives in the next little while.

good thing about ocz vertex 4 is that its got 5k P/E write cycles i think. I am not so sure about samsung, probably 3k

Plextor M5P is reported to have a very good effect on battery life and with 19 nm I’d need a comparison before declaring this one the winner
