Samsung 840 250GB Conclusions

The way I see it, Samsung’s introduction of the 840 now puts them in a couple of “special spots” in the SSD market. First and foremost, Samsung manufactures the 840 completely in house. Controller, NAND, DRAM cache, everything. This means cherry-picking of the best NAND off each wafer, better NAND/controller integration, ability to do much more validation/testing, and faster firmware turnaround times if any tweaking is ever needed. Second, Samsung now has access to a TLC NAND based SSD product. TLC NAND is roughly 30%-40% cheaper than MLC (2 bit per cell) NAND, so it gives Samsung a lot of room to become much more “competitive” if so desired. Considering current pricing on MLC NAND based products on the market, I wouldn’t be surprised to see the Samsung 840 regularly selling for $0.50/GB by Q2 2013.

Performance on the Samsung 840 was definitely unexpected especially since it seemed like Samsung spent a lot more time promoting the 840 Pro and downplaying the 840 during their SSD Summit. While it’s true sequential writes were lacking, most client workloads are focused towards random reads and writes, which is precisely where the Samsung 840 excels in. This is why the Samsung 840 was able to top the charts in PC Mark 7 despite most other drives being advertised as having significantly faster sequential writes. Of course, those of you planning on using the drive in scenarios where constant sequential writes are needed, you might want to check into the Samsung 840 Pro, but for general computing, the Samsung 840 should be a beast of a drive that’s more than capable of fulfilling most general consumer needs.

Samsung 840 Samsung 840 Samsung 840
Capacity 120GB 250GB 500GB
Model MZ-7TD120BW MZ-7TD250BW MZ-7TD500BW
Price $109.99 $199.99 $549.99

Pricing on the Samsung 840 250GB is expected to be around $199.99 for the bare drive, which puts it at well under $1/GB even at MSRP pricing. Looking at the 120GB and 500GB drives, it seems like pricing is either around or under $1/GB, which will make the entire Samsung 840 lineup extremely competitive when it launches next month. Samsung will also be offering the 840 with a combination desktop/notebook kit for an additional $20, which includes stuff like a 2.5″ to 3.5″ bracket, 2mm riser, etc., which isn’t too bad for those who need the extra stuff.

Warranty on the Samsung 840 is a very standard 3 years, which is a bummer especially with the 840 Pro getting the coveted 5 year treatment. Given that TLC NAND is a fairly new development in consumer SSDs, it would definitely inspire a lot more confidence into the generally less durable NAND if Samsung were to offer a 5 year warranty. However, it seems like Samsung is quite confident that the TLC product will be as durable as MLC (2 bit per cell) offerings, so we’ll see what happens in the coming months. Given Samsung’s excellent track record in the SSD market, there shouldn’t be any problems, but it’s definitely something to keep in mind. That said, I will be using the Samsung 840 extensively until its retail launch, so I’ll be sure to post any updates on the drive if any problems do arise.

Bottom Line

With the 840, Samsung has done a remarkable job showing us that TLC NAND can and will be a viable solution for more affordable, larger capacity SSDs from this point forward. While long term durability is still up in the air pending mass user adoption and long term testing, Samsung’s pricing and their reputation as a tier 1 SSD manufacturer makes the 840 a very attractive option when it begins shipping in October.

    What I don’t understand is the short warranty period compared to the 840 pro, and the price is fairly similar.
    I don’t know which one would be the best, but with the “minimum” price difference in mind and the unknown durability of this TLC product I’m not really sure where exactly this SSD stands.
    Between the warranty of the Pro, the fact that it has less power consumption, 6Gb more, and it will probably last longer.
    I’m having trouble deciding which one to choose. I plan to have it for a long time using it for the windows and some programs along with a HDD store the everyday data (photos, word documents, etc.), therefore, better get the Pro?

      The 840 looks like it will be a pretty good drive, but it is slightly inferior to the 830 it’s replacing. The 840 Pro looks like a fantastic drive but the prices are extremely high. The 830 is being heavily discounted right now, and is by far the best value for the money of the three. I have one and it’s fantastic, I’m considering getting another.
      The 840 should be a pretty good drive, and because of the TLC memory, prices on it should come down rapidly – but it’s currently priced above the 830 and it doesn’t make much sense to buy one until prices drop quite a bit – which they should in a few months.

    Where is this migration software. I just purchased a 256GB 840 Pro from Newegg. There is no data migration software here. Just the magician stuff, which points me to a link to download Norton Ghost, for which I was not provided a license key. ???

      You need to download it from Samsung site.

      The migration software is available at the Samsung website (linked below) if it didn’t come with the SSD. Unfortunately, I received a pre-production sample, so I’m not sure what’s actually in the retail boxes.

    I am worried about CrystalDiskInfo B1 parameter: 3E –> 93% after only one hour use…

    I bought a 840 pro 128Go… 00 –> 100% at first start. 0C –> 99% after Windows 7 install…

    Very strange, and what about the 5 years warranty, limited to max write cycles parameter…
