The hardware brings higher capacity minuscule performance

Samsung still hasn’t released an 8TB M.2 NVMe SSD, but today’s launch of the 870 QVO includes a lineup of second-generation QLC SSDs with capacities up to 8TB and in our list of best drives Must compete for a spot. solid state. However, unlike Sabrant’s brutal 8TB Rocket Q which landed in the M.2 form factor, the Samsung Drive comes with a SATA interface.

Packed with the company’s own V-NAND 9x-layer QLC flash and a new controller, the Samsung 870 QVO aims to be the highest-capacity 2.5-inch SSD you can find, but the king of the Tall 8TB model It is not until August. Right now we have a 1TB model to test us to find out how the new drives will stack.

We are no strangers to high storage capacity, but we were a little surprised to see a third-party product like the 8TB Rocket QSSD from Sabrant before the storage division of the powerful Samsung SSD rolled us out to the 8TB bomb. However, even though the Sabrant’s Rocket Q offers high performance as well as its prolific capability, it is still quite expensive. Samsung, in contrast, says it does not like to jump ahead and introduce a product to the market ahead of time. Instead, the company says that it has waited patiently for both customer demand and price, which is why we have not seen the company launch consumer of 8TB SSD till date.

Right now, aside from a passionate videographer or data scientist, there are not many users who need 8 TB of a laptop. Sure, data eating, sleeping, and breathing are hoarders of SFF PCs, but how many users really need a combination of 8TB with NVMe speeds? For most users looking for heavy flash storage, an inexpensive, high-capacity SATA SSD is usually a great step up from the hard drive, especially in terms of durability on the go.

The 8TB 870 QVO was recently leaked at more than $ 900, but Samsung says it will announce the final price when it actually ships the drive. Until then, we have to settle for the available 1 TB-4 TB options that cost $ 500 from Samsung (at the time of writing). Unfortunately, QVO’s QLC flash, which enables up to 8 TB of storage, requires sacrifice in performance and durability, and a three-year warranty and higher prices make other options more attractive.

Around $ 0.11– $ 0.13 per GB, Samsung priced 870 QVO lower than the 870 QVO launch price. The company says it has improved random performance by 13% compared to 1% in Q1 depth (QD) for the new controller and flash.

The QVO spec lists speeds up to 560 / 530MB / s sequential read / write transfer rate and up to 98000/88000 IOPS random read / write. Samsung SLC relies on these speeds on caching performance, but after filling in the cache, write performance will drop to a much slower speed. We will test it on the next page.

To deliver responsive performance and durability, the Samsung 870 QVO uses the same Smart Turbovite SLC buffering mechanism as the 860 QVO. Samsung’s TurboWrite smartphone is a hybrid caching implementation with 6GB fixed SLC cache at all capacities for 860 QVO and additional dynamic cache capacity of 36GB or 72GB (varies depending on drive capacity). For a 1 TB 870 QVO, the TurboWrit Smart Cache size is 42 GB, while the higher capacity model has 78 GB of cache.

The carrying capacity of the 870 QVO is much higher than many QLC competitors, such as Sabrent’s Rocket Q, Intel’s SSD 665p and Crucial’s P1. With top-of-the-line turbovit technology with low-density parity check (LDPC) ensuring data integrity, the Samsung 870 QVO ensures 360 terabytes of data per 1 TB capacity or for three years, whichever comes first.

The short warranty is disappointing when we see that most SSDs in the 870 QVO price bracket are supported by a five-year warranty and often have a more permanent TLC flash. The Q70 supports QVO encryption features that many SSDs lack. In addition to support for common features such as trim, smart data reports, and secure wipe, it also comes with TCG Opel 2.0 compliant AES 256-bit hardware encryption (IEEE1667 specification).

Programs and stuff

The Samsung 970 does not ship any accessories with the QVO, but the company provides software support. Samsung’s wizards and migration tools are available to download on the company’s website and allow you to monitor, measure and update Samsung SSD firmware, performance measurements and updates, as well as cloning your old data onto a new SSD. even do.

The Samsung 870 QVO 2.5 ” comes with a 7mm SATA form factor and features an all-metal casing that sets it apart from most SATA SSDs, which come with cheaper plastic sheets, as well as earlier. The 860 is slightly darker gray than the QVO.

Samsung has kept the internal components to a minimum. The Samsung 870 QVO comes with a new SATA 6Gbps SSD controller, but the company is agile on hardware details. We know that the console relies on ARM architecture, as Samsung has always done, and it bears the name MKX. We also see Metis embossed on the console package, but this is so.

Based on SSD specification and test performance, the new MKX ‘Metis’ controller MJX should be similar to the three-core MJX ‘Maru’ SSD versatile controller the company uses on the 860 QVO, EVO, PRO and DCT models. In addition to the possibility of having three CPU cores, it also supports DRAM and can have eight flash channels with eight chips each capable of interacting with flash memory. The Samsung 870 QVO uses 1GB of LPDDR4 RAM of controller capacity to use as buffer space to manage NAND and background tasks, while console cores manage host interactions and read and write tasks .
