Samsung 840 Evo: A Handy All-New SSD with Turbo Write Technology Offering Performance at a Cheap Price

The new Samsung 840 Evo has introduced a much-needed feature called TurboWrite Technology that has placed SSDs on top of the performance chart. This SSD makes use of single-layer cell (SLC) NAND flash memory, a kind that is commonly employed in high-end enterprise SSDs. The purpose of this part is to act like a buffer. The data is first moved to this buffer and then written to other regions of the SSD when the drive is idle. Turbo Write can improve the performance significantly, as an SSD is generally idle for a good length of time in real-world usage.

When the Samsung Hard Drive is not being used (idle), it consumes very little power (0.045 watts). Most regular hard drives or other SSDs use a minimum of 0.5 watts. This is a good innovation that has made this drive apt for use in laptops. The Samsung 840 Evo can be used across many platforms, including Windows, Linux, and Mac OS X. However, if you want to use the software bundled with the drive, you should have Windows.

Cost Per Gigabyte and Warranty

Pricing is an important consideration when it comes to choosing SSDs. Luckily, 840 Evo does not carry the same price tag as the other high-end or regular SSDs. It gets into the competition offering five capacities of 120GB, 250GB, 500GB, 750GB, and 1TB at cost $110, $190, $370, $530, and $650, respectively. If we calculate the cost per gigabyte, it is less than 80 cents per gigabyte for all (except for the 120 GB drive).

Samsung 840 Evo has a warranty period of three years as compared to the five-year warranty offered by 840 Pro and other high-end drives. This is rather expected of a drive that is just an entry-level in the market.


When it comes to performance, the Samsung 840 Evo works impressively well. You can expect your system to take just 10 seconds to boot and even less to shut down. You can have all your applications to load almost instantly and the system to wake up from sleep very quickly.

The company boasts that the drive will offer a write speed around 267 MBps and a read speed of 184 MBps when performing simple data-copy operations. This drive may slow down a little when it is used as the main storage drive. You can expect the drive to perform the best with RAPID turned on.

The Samsung 840 Evo is your best bet for the performance, price, and capacity it offers. The drive brings the cheapest price of SSDs to the market with 1 TB model offering just 65 cents per gigabyte. It may move the SSDs on the top when compared to hard drives in many respects.
