Samsung Electronics | Published on 21 Mar 2021 | Written by Dr Jiulin Teng w/ Neosummarizer

Overview

  • Very good sequential write performance for almost all of the test duration
  • Very low energy usage
  • Very good write performance
  • SLC cache size could be larger

Summary

Samsung boasts the 870 QVO as best-in-class in terms of sequential read and write speeds. Still, as a QLC drive, the 870 QVO offers a mere fraction of the post-cache write speed of mainstream TLC drives. Even DRAMless TLC drives offer much better sequential write performance for almost all of the test duration.
This rundown provides our analysis on 8 third-party reviews. The sentiment scores, summaries, and key takeaways that we select are based on these reviews and may differ from the original publication.

Reviewers from Anandtech have found the following[***]:
At 42GB this model's cache can still handle more writes than many users perform in an entire day of desktop usage. Both capacities of QLC drives offer a mere fraction of the post-cache write speed of mainstream TLC drives. The 870 QVO is still trading wins against DRAMless SATA drives with TLC NAND.

Pros[**]
  • Strong sequential write performance compared with mainstream TLC drives
  • Quieter than most 4TB drives
  • QLC NAND improves performance after SLC caches run out
Cons[**]
  • Lackluster write performance when SLC cache runs out
  • SLC write performance could be better

Sentiment Score[*] 56%
Reviewers from Anandtech have found the following[***]:
The 8TB Sabrent Rocket Q is a M.2 NVMe drive from a brand that's working to stand out from the crowd. Write endurance ratings of 0.1 to 0.3 DWPD appear inferior to the 0.5 DWPD or more from good consumer TLC drives. SLC caching helps address most of the remaining performance problems.

Pros[**]
  • Large SLC cache
  • Good random read performance
  • Good sequential write performance
Cons[**]
  • SLC cache is a bit large for a QLC drive

pcmag[3]

Sentiment Score[*] 87%
Reviewers from Pcmag have found the following[***]:
The Samsung SSD 870 QVO is aimed at both professionals and mainstream users. It's a 2.5-inch Serial ATA (SATA) 3.0 drive that has no problem keeping up with its NVMe-based cousins. Samsung rates the drive to hit a maximum sequential write speed of 530MBps.

Pros[**]
  • Powerful sequential write and sequential reads
  • 4K random read is the best in the class
  • Easy-to-use software package
Cons[**]
  • Nothing in particular

pcworld[4]

Sentiment Score[*] 81%
Reviewers from Pcworld have found the following[***]:
The Samsung 870 QVO is a standard 2.5-inch SATA 6Gbps SSD. It's a great everyday performer; however, when you run out of cache (which shouldn't be often) write pace falls off drastically. The drive is warrantied for three years, and is rated for 360TBW (TeraBytes Written) per 1TB of capacity.

Pros[**]
  • Great everyday performance
  • 8TB of NAND on board
  • Very fast write speed
Cons[**]
  • SLC cache is not as good as SLC cache

techradar[5]

Sentiment Score[*] 75%
Reviewers from Techradar have found the following[***]:
Samsung's 870 QVO is the second iteration of its budget budget line. The drive is available in four versions: 1TB, 2TB, 4TB and finally 8TB. It uses Samsung's second generation 4-bit MLC V-NAND paired with the new MKX controller.

Pros[**]
  • Impressive sequential and sequential write speeds
  • Solid price-per-gigabyte ratio
  • Solid build quality
Cons[**]
  • SATA interface runs on a SATA interface

tomshardware[6]

Sentiment Score[*] 76%
Reviewers from Tomshardware have found the following[***]:
The Samsung 870 QVO aims to be the highest-capacity 2.5" SSD you can get your hands on. Unlike Sabrent's monstrous 8TB Rocket Q that landed in the M.2 form factor, the Samsung drives come with the SATA interface. Samsung says it improved random performance by 13% at a queue depth (QD) of 1 thanks to the new controller.

Pros[**]
  • High performance and endurance
  • Three-year warranty
  • Sleek design
  • Supports QLC flash
Cons[**]
  • Only one year of warranty
