Questions about Samsung 870 QVO

According to the specification, no cable is included. This is normally included with the mainboard.

Thanks for the info! We have immediately forwarded this to the appropriate department for review and correction.

It is fully compatible with HDD 2.5, so it is suitable for PS4. Difference to 860? Well, everyone is moving with the times and bringing out new models. It's a little faster and even a little cheaper. :-)

Yes, flawless. I use two of them in a DS918+.

The Samsung 870 QVO SSD is a 2.5-inch model that has a SATA III interface. However, the Icy Box IB-3805-C31 enclosure is designed for 3.5-inch hard drives. Therefore, it is not possible to install the Samsung 870 QVO SSD directly into this enclosure as it is not the right size. You need an enclosure that is specially designed for 2.5-inch SSDs.

According to the Acer website, the Acer Nitro 50 - N50-610 is a desktop computer with two M.2 slots. If you have never upgraded the PC before, only one of these two M.2 slots should be occupied by an SSD. This means that you can install another M.2 SSD. (However, I do not know which type of M.2 SSD will fit, as there are also differences here). SSDs with an M.2 interface are much faster than SSDs with a SATA III interface (like the Samsung 870 QVO is). I therefore recommend buying an M.2 SSD instead of the 870 QVO, unless you absolutely need 8 TB of storage space or want to be able to take the SSD with you, as M.2SSDs are only available at reasonable prices for private customers up to 4 TB and are usually permanently installed in the PC (however, there are also external housings for them, in which case they can no longer fully utilise their speed advantage over SATA III SSDs). Two more notes on the service life and speed of the Samsung 870 QVO: This SSD uses QLC NAND cells (Quad Level Cells), i.e. 4 bits are stored per cell. This means that it is slower than SSDs with TLC NAND cells (Triple Level Cells: 3 bits per cell), MLC NAND cells (Multi Level Cells: 2 bits per cell) and SLC NAND cells (Single Level Cells: 1 bit per cell). However, it is cheaper. However, their average service life is also shorter, as each NAND memory location only allows a certain number of write cycles and, due to the storage of 4 bits per cell, each cell is naturally subjected to more stress than with TLC, MLC or SLC SSDs. The Samsung 870 QVO with 8 TB has a so-called SLC cache of "only" 78 GB. When data is written to the SSD, this cache is filled first. This happens very quickly because it consists of SLC NAND cells (see above). If the SSD has nothing else to do, the data is then copied to the slower QLC NAND cells in the background, freeing up the fast SLC cache. Thanks to this SLC cache, the write speed is fast (max. 530 MB/s, the SATA III connection is the bottleneck here). But if you write more than 78 GB at a time to the SSD, the write speed drops drastically (to only approx. 160 MB/s). SLC caches and DRAM caches are frequently used in SSDs. The QVO 870 is therefore not an outlier in this respect. The only special feature here is that the SSD is relatively large, but its SLC cache is relatively small in comparison.

Yes, I've had two of them running in my DS220+ for a year. They worked perfectly for me.

I use the SSD in a UGreen enclosure that was recommended for it (USB 3.2) and switch between iMac and MBP, works wonderfully. https://www.amazon.de/dp/B07D2BHVBD/ref=pe_27091401_487027711_TE_SCE_dp_1

Is the SSD partitioned as MBR or GTP? If it is MBR -> partition according to GTP.

I have a DiskStation DS620slim (6 x 2.5") and can recommend: https://www.synology.com/de-de/products/DS620slim Has power and speed, is quiet and economical. Disadvantage: it's not cheap.

The biggest difference will be the max TBW and the warranty period: 600 TB - 5 years - Samsung 870 Evo 360 TB - 3 years - Samsung 870 QVO

Samsung Electronics GmbH Hello, thank you very much for your enquiry. For the Samsung SSD 870 QVO SATA III 2.5 inch, your device requires a SATA 6 Gb/s interface, although the SSD is also compatible with a SATA 3 Gb/s & SATA 1.5 Gb/s interface, as well as a free mounting bay in the 2.5 inch form factor. If in doubt, please check with the device manufacturer. Kind regards from Schwalbach Your Samsung Service Team

Yes, unfortunately the price graph is not yet as reliable as desired, but the responsible department is working on it.

Addendum: I am now the happy owner of the matching screws. Flat countersunk head screw (M3x3mm, length 4mm / cross recess with 5mm diameter). -> just type "InLine 77781A" into Google, and a dealer with A. will appear automatically. It's a pity that the matching screws can't be ordered from Digitec/Galaxus.

Good day, If the SSD is used for Time Machine, I assume that the actual internal 870 QVO is connected externally (SATA6 to UAS (chip in the adapter connector)), then the SSD is connected to a USB 2 or USB 3 or USB-C Gen 1 or Thunderbolt-c. I have had very positive experiences with Windows 10 and such connections in terms of speed. Only once did an SSD with Thunderbolt crash (total data loss). I'm still working on the cause (cable?, adapter plug?, chip set? etc...). As for Apple: if everything was built transparently, it should work technically. Unless Apple has built in a check that prevents "wild" components from being used. Greetings Daniel
