Review Samsung SSD 840 'Basic' Series: 250 GB


Fast and affordable? Compared to the high-end Samsung 840 Pro, the 'non-Pro' 840 uses the same controller but considerably less durable TLC (Triple-Level Cell) NAND Flash modules. Should that stop you from investing in this economical SSD? Keep reading...

On the other hand, the difference in everyday use should not be overly dramatic. Boot and load times are similar with all modern SSD, something that is also evidenced by the more general PCMark benchmarks

Samsung 840 Series 250GB


The Samsung 840 Series is an excellent SSD for those on a budget. Early reliability concerns regarding TLC NAND are apparently unwarranted.

Best price per GB ratio we've seen yet thanks to Samsung's Triple-Level Cell NAND

New dense NAND isn't quite as fast as established technology

One of the most significant shifts in semiconductor manufacturing in the past five years has been Samsung's rise to power in the NAND flash market. While Samsung has been manufacturing drives for years, the company has only recently begun to focus on...

Samsung 840 (500GB, SSD)


The Samsung 840 series, which is not to be confused with the recently reviewed Samsung 840 Pro , is not really an upgrade to the no product found for id 35020154 Samsung 830 series that was released more than a year ago. The new drive belongs to...

The Samsung 840 series solid-state drive (SSD) is affordable, good-looking, and offers very good performance.

The Samsung 840 comes with just three, not five years of warranty coverage and is likely to have shorter lifespan than others of the same capacity.

The Samsung 840 series is an excellent entry-level solid-state drive for budget and general users, but not really a good buy for advanced or professional users.

Samsung SSD 840 (250GB) Review


The 840 is quite average in our Heavy suite and performs similarly to most SandForce drives. The 840 Pro is a lot faster under heavy workloads, so it should be obvious by now why Samsung is offering two SSDs instead of one like they used to.

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with...

Samsung 840 120GB SSD Review


The 120GB Samsung 840 Series SSD features the powerful 8-channel MDX controller and TLC NAND. While this value SSD comes at a very good price, it also features much lower speeds than its larger capacity brethren. We put this value SSD through our suite...

While we continue to recommend higher capacity Samsung TLC Model 840 SSDs, the TLC-equipped 120GB 840 Series SSD is simply not a good option for consumers. 3.5 to 4 years of projected light use is an endurance concern that users would be advised to...

Samsung 840 Series 500GB TLC SSD Review


Samsung has released the first TLC NAND equipped SSDs into the market, creating the lowest price points we have witnessed for SSDs bringing large capacity SSDs within reach for average users. Today we test the 500GB TLC Samsung 840 Series SSD to test...

Samsung 840 Series TLC 250GB SSD Review


Samsung leads the way by introducing the world's first SSD equipped with TLC NAND into the market. The Samsung 250GB 840 Series SSD looks to shake up the market by providing an excellent dollar-to-performance ratio by leveraging low cost NAND and the...

The Samsung 840 Series requires users to know their workload before making the jump. This SSD should be fine for the casual user, but for those with heavy write workloads there will be penalties in overall speed and endurance. Samsung is looking to...

Samsung 840 Series 250GB SSD Full Review - Time for some TLC


At this event, Samsung officially announced their new 840 Pro, which we were able to obtain early under NDA and therefore publish in concert with the announcement. The 840 Pro was largely an incremental inprovement over their 830 Series. Newer, faster...

You won't even notice it working its magic, but the Samsung 840 Series powerful solid-state drives can be a big boon for your computer. Learn more in our review.

This device uses hardly any power while operating

This solid-state drive does not come with a 3.5-inch mounting kit

The Samsung 840 Series is a good choice for those who are looking to upgrade from an old hard disk drive.

Samsung 840 500GB SSD Review


The Samsung 840 is the first consumer drive of its kind. What makes the Samsung 840 different than any other drive that has been launched to date is the type of NAND utilized. The 840 series is equipped with Triple Level Cell (TLC) NAND. Samsung is the...
