Samsung apparently does not bake small rolls. The Koreans have extended their SSD range by two models. Two features immediately catch the eye of the connoisseur. On the one hand: the storage capacity of the new SSDs has been doubled – from one to two terabytes. Such large storage capacities have so far not been present on the consumer market. At an attracted price of around 850 euros it is also clear that a demanding clientele is addressed here.
In the twilight of the data rate

More emphasis on real requirements
On the other hand, the controller - the Samsung MEX - used for this model series and memory size was replaced by a Samsung MHX. The 3D VNAND memory, which is still being produced in the second generation with 32 levels and in the 40-nm manufacturing process, remains the same. Overall, the trend towards new, high-performance controllers is felt by all manufacturers.
Test winner: Samsung SSD EVO 2 TB
No wonder, because modern SSDs are already at a very high level with their data transfer rates and are slowly but surely reaching the limits of the SATA III specification, which provides data transfer rates of up to 600 MB per second. Since, however, a protocol overhead is always sent with data transmission for every type of data transfer, the 600 MByte is a theoretical value. The only exception is a compressed data transfer. Here it is quite possible to reach or even exceed the specification.
Preistipp: SanDisk Ultra II
Consumers have now also understood that it is not only a maximum transfer rate is important. Most SSDs are used as a system drive, for example under Windows. The "wow effect" at speed - especially in direct comparison with an HDD - is the greater the better the SSD and its controller can deal with smaller files Code>
For this reason, we have changed the weighting of our laboratory tests in favor of data transfer performance for 4 KB files. Performance still has a 70 percent share of the overall rating, but the weighting has shifted in favor of the 4K data transfer. Let's take a look at the test candidates and their test results.
The Samsung EVO 850 with 2 terabytes reaches outstanding values on our test platform. In the AS SSD it achieves a very good 1,638 points. In particular, the write values for 4K files stand out with just under 97 megabytes per second. This value is twice as high as with many other SSDs and an indicator that the Samsung is particularly suitable for use as a system disk. This result is again confirmed by the ATTO benchmark. Here, it is particularly noticeable that the EVO 850 already achieves high transfer rates for small file sizes.
Reading Tip: Benchmark Tools for PC
For 2 KB files it is over 100 MByte / s and with 4 KB files it is already over 200 MByte / s. Samsung uses the red pencil for extras such as spacers, screws or mounting frames. Samsung grants the EVO buyers a five-year warranty. If you would like to have ten years, you have to go to the PRO and get around 100 euros more deeply.
With 90 points and a road price of 95 euros, the SanDisk Ultra II comes at the best price / performance ratio of all our test lab candidates. The sequential read and write rates (536/511 GB), the data rates on 4K files and the access times make the Ultra II a very good SSD. The SanDisk, which works with TLC memory and an SLC cache, is excellently equipped for use as a system disk. If you are looking for a bargain, grab here. But: SanDisk is only providing a three-year warranty on the TLC memory. Users with an enormous amount of writing are better advised with an SSD with a longer guarantee.
The Plextor M6 Pro is equipped with 512 MB DDR3 SDRAM as an additional cache. Plextor uses high-quality components for the M6 Pro with this flash memory from Toshiba and the Marvell 88SS9187 controller. Five-year warranty and 2.4 million MTBF (Mean Time Before Failure) indicate the use of high-quality memory. In sequential reading and writing, the M6 516 reaches around 476 MByte / s - very well. When transferring 4K files, the Plextor SSD reaches a very high value of more than 74 MB / s.
With around 58 cents per gbyte, the Vector 180 is not the cheapest SSD. But it also offers more than many others. In addition to screws and mounting frames, OCZ is donating an Acronis True Image for a smooth operating system migration. In addition, OCZ has missed the Vector 256-bit AES encryption. It is protected against data sieves.
The change from Sandforce to Indilinx controller has not hurt OCZ. In the transfer rates of 4 KB files, the Vector 180 has added over ten percent compared to the Vector 150. Something has decreased the maximum transfer rate with compressed data, but with 557.95 MByte / s is still very high. Temperature development and CPU load are pleasingly low. The manufacturing guarantee and the MTBF of 2.3 million hours are above average.
Plextor M6 Pro
As a controller, the Samsung SSD 850 Pro is already used in the 840 SSDs used development MEX. The difference: The 850 series is the first with 3D V-NAND memory. Samsung is the 1-terabyte SSD an entire GByte LPDDR2 cache.

OCZ Vector 180
This guarantees very high data transfer rates to the flash memory. Although this PRO does not reach the speed of the 2TByte-EVO with MHX controller during 4K-data transfer, but for all other values it plays in the same league. The Samsung Pro is a 10-year warranty, especially for professional users who like to pay extra.
The Savage from HyperX is an SSD with very good transfer capabilities and a comprehensive set-up - even the Clone software True Image is there. Case modders with acrylic windows in the tower will love the Savage already because of their fancy design, especially since the price of 45 cents per Gibibyte is very fair. Only the short 3-year warranty and an MTBF of 1 million hours interfere with the quality-conscious buyer.
If you want a 500 GB SSD at an affordable price, the ADATA SP610 is well advised. In the test lab, it achieves a very good 517 MB / s when reading and a respectable 412 MB / s for sequential writing. The maximum read rate was 563 MB / s and was determined with a file size of 256 KB: An indication that the ADATA is also a good choice as a system disk. But even in writing it reaches a good value in the top with 452 MB / s. The CPU load is idle and under load between 2 and 2.5 percent. ADATA adds Acronis True Image HD, a spacer, and a built-in adapter to the package.

Micron Crucial MX200
PNY CS2111
Micron is one of the first manufacturers to integrate 16nm technology into its SSDs. The maximum reading speed is 532.8 MBytes / s with a file size of four megabytes. When writing, the Micron Crucial MX200 achieves a maximum of 517.5 MB / s. Good: For four KB data the read speed is over 100 MByte / s. This is beneficial for a fast Windows startup. Micron adds a Spacer and Acronis True Image to the package. Alternative: The BX100, without Acronis, is around 70 euros cheaper.
The new PNY CS2111 has a hard time keeping up. The data rates are good - but not more. Even the price of 50 cents per Gibibyte is not a special purchase incentive, but rather the design.
