![]() ![]() The controller on the Samsung 850 EVO 4TB is the Samsung MHX controller (Model #S4LP052X01-8030). Despite the high capacity, Samsung is only using a 3/4 size PCB with just 8x NAND packages, a controller and a DRAM package. Inside the casing, we can take a look at the PCB. By now we’re very familiar with this case design which is used in nearly all of Samsung’s SATA SSD offerings. Here’s a closer look at the Samsung 850 EVO 4TB. Included in the packaging is a couple pieces of documentation, a software disk, and the Samsung 850 EVO 4TB drive. Here’s a look at the packaging for the drive. Today we’ll be reviewing the Samsung 850 EVO 4TB. A Closer Look at the Samsung 850 EVO 4TB For most consumer and even business applications, a 300TBW endurance should be more than enough especially given Samsung’s generally conservative specifications. ![]() Warranty on the new Samsung 850 EVO 4TB is rated at 5 years with an endurance rating of 300 TBW. Despite the Samsung 850 EVO 4TB designed as a drive for the mainstream user, its performance ratings easily match those of high end SATA SSDs thanks to Samsung’s top notch TurboWrite SLC cache implementation. 4K random reads are rated at 98,000 IOPS and 4K random writes are rated at 90,000 IOPS. Performance on the Samsung 850 EVO 4TB is rated at 540 MB/s sequential reads and 520 MB/s sequential writes. The new memory’s massive 256Gb dies enable the drive to reach its massive capacities. New for the Samsung 850 EVO 4TB is the use of new 48-layer 3D V-NAND which was unveiled recently at Flash Memory Summit. The new controller is similar to the older MGX controller however, it supports capacities higher than 1TB. Powering the Samsung 850 EVO 4TB is the Samsung MHX controller which was first unveiled with the Samsung 850 EVO and 850 PRO 2TB last year. Samsung 850 EVO Specifications Manufacturer As such, when we got the opportunity to test the monstrous 4TB Samsung 850 EVO SSD, we jumped on it. Considering 1TB was the largest capacity just 4-5 years ago, a 4TB drive designed for the consumer is a really huge deal, no pun intended. Really Big.Īt Flash Memory Summit earlier this year, Samsung announced their new 48-layer 3D V-NAND and along with that they announced that they’ll be using the new NAND in their 850 EVO SSD, pushing capacities up to a staggering 4TB. ![]()
