Samsung 850 evo 4tb ssd review
At the end of June, Samsung released the 850 Pro which was the successor khổng lồ the 840 Pro. With it came their brand new 32-layer MLC 3 chiều V-NAND flash, và this flash allows for greater durability, lower nguồn consumption, improved performance & a 10 year warranty. This morning we are reporting on Samsung’s 850 EVO, the successor lớn the 840 EVO, and get ready for it as this SSD is going lớn rock your socks off.

What could Samsung have done khổng lồ make their EVO series even better this round? They have thrown in a new controller for the 120GB-500GB models as well as their newest 32-layer TLC 3 chiều V-NAND. With its new controller và 3D V-NAND, it performs lượt thích an F1 race car, yet is as efficient as an electric car! Quick burst speed and efficiency is what this drive is about. Most client PC workloads are relatively quick & small, therefore, building a drive that is optimized for low queue depth performance is important for daily client usage. The Samsung 850 EVO delivers.
Furthermore, base “After TurboWrite” performance has increased. After TurboWrite performance is reveled when a write operation exceeds the kích thước of the buffer, the write speeds will drop to the following in the chart below.
However, most everyday usage will allow for TurboWrite speeds nearly all the time.
Finally, in terms of sheer speed, Samsung’s RAPID Mode has been updated once again. With Magician 4.5 comes RAPID Mode version 2.1 which enhances error handling và fixes compatibility issues with IRST. More interestingly, however, is that the new RAPID mode will allow for almost x1.8 performance gains at Windows start up và application loading. Stay tuned for some more detailed testing on it later this week!
Speed isn’t the only thing that has improved with the 850 EVO; endurance has as well. The 120/250GB models are now rated for 75TBW và the 500GB/1TB models are rated for 150TBW, with MTBF rating being 1.5 million hours.
These drives come with AES 256-bit Full Disk Encryption (FDE) TCG/Opal V2.0 and support Encrypted Drive (IEEE1667) which can be activated easy with instruction from within Samsung’s Magician software. Samsung Magician’s Rapid Mode can also be enabled in their software. Furthermore, TRIM is supported when there is OS support. They feature S.M.A.R.T. And garbage collection as well as a five year warranty. We are glad to lớn see the jump from a three year warranty khổng lồ a five year, especially for a value tiered SSD, however that 10 year mark would have been real sweet.

PACKAGING & COMPONENTS
Samsung has done somewhat of a flip in packaging, choosing lớn go with trắng on black this time around, rather than their typical đen to differentiate the 850 Pro from the 850 EVO lines. Inside the packaging you will find a software CD, installation guide, & warranty papers.
Aesthetically, Samsung moved from grey as a primary color. The 850 EVO casing now looks the same as the 850 Pro, save for the grey box on the front, rather than orange.
When we first picked up the 120GB 850 EVO, we noticed immediately how much lighter it was than other 2.5″ SSDs we had tested in the past. This built our curiosity as we cracked open the shell khổng lồ see what it contained. The 120GB PCB is tiny, even compared khổng lồ the half kích cỡ PCB of the 500GB model. This SSD has lớn have a world record for its light weight of 41 grams. Khổng lồ put that into perspective, a standard notebook hard drive weighs around 92 grams.
On the front of the PCB there is only one single NAND package, a controller, & a DRAM chip. As mentioned earlier, it is their new MGX controller. We were unable khổng lồ get much information on it at this time, but we should be getting a response back from Samsung soon with more details on it. The NAND is their new 32-layer TLC 3 chiều V-NAND. When formatted in an OS the capacity is 119GB. Finally, the DRAM chip is 256MB of LPDDR2 for the 120GB model. Twice the amount than we are used lớn seeing on drives. Typically it is a 1:1 ratio of MB of DRAM to lớn GB of NAND.
Out of its casing, the 500GB model is a half kích cỡ SATA PCB, just like that of the 850 Pro. On the front of the PCB there are two NAND packages, a single controller, and a single DRAM chip. On the back there are two more NAND packages, bringing the total to lớn four.
The NAND is the same, when the drive is formatted the usable capacity is 465GB. The controller is also the same, the only mã sản phẩm to vary is the 1TB, which features a MEX controller. The amount of DRAM used in the 250GB và 500GB models is 512MB LPDDR2 & the 1TB mã sản phẩm hosts 1GB LPDDR2.
