Waiting for QVO 1TB to hit the $145 mark again before CB
EDIT: Misread
Cashback ends June 16th anyway. Still about 2 months for SSDs to continue to drop in price.
Still remember 3 months ago people wait impatiently for ssd to hit under $200 for 1TB. With $40 cash back from Samsung, I made an EVO for 145.
The QLC on the 2TB is significantly faster than the 1TB. 80mb/s vs 160mb/s. Also the 2TB has a larger SLC cache.
noob question, are you reffering to the EVO or QVO?
The QVO. The EVO is just faster all round.
- Those are the sequential write speed after the SLC cache is filled.
- 2TB is faster simply because of the doubled number of NAND channels. The memory cells are the same and they work at the same speed.
Any cheap SSD's around the quarter terabyte range?
250GB is very poor value these days. 500GB is generally 50% more $$$ for 100% more capacity and slightly better performance.
It's $155 at umart
Shows as $159 at Umart for me and doesn't include shipping. This works out at $156 including shipping for the QVO model.
Can’t stack my $49 ebay plus voucher with this, eBay!!!!!!
Hey guys, I just want to bore you on the QLC / QVO, about its performance and durability.
The data is read off of it at 550mb/s, so load times are comparable to any SATA SSDs.
When writing to the drive, you first fill up the SLC cache at the very fast speed of 520mb/s, and in the background it then transfers that data to the QLC storage.
The 1TB has a cache size of 42GB, so if you are transferring from another SSD to the QVO, once you've transferred more than 42GB in one go the transfer speed will drop to a slow 80mb/s.
The 2TB has a cache size of 78GB and whe full the QLC transfers at 160MB/s.
If you primarily download from the internet, I'm pretty sure you don't download faster than 80MB/s or 160MB/s.
For durability, the 1TB has 360TB Write Endurance, while the 2TB has 720TB. If you write 250GB a day, every day, the 1TB QVO should last you 4 years while the 2TB should last you 8 years.
The biggest downsides are:
Latency, which can be lower when compared to non-QLC SSDs, but still much faster than any HDD.
When it gets full up, the closer you get to 100%, you'll lose access to the SLC cache, leaving your transfer rates at 80MB/s or 160MB/s.I reckon the QVO are great for game installations, where you download the game from the internet. You'll probably never encounter slow downs in that example.
Awesome info, cheers! So how does the cache work, using the 2tb for this example - if you’re transferring more than 78gb at once, does the cache proceed to empty at the 160mb/s speed WHILE also being filled, thereby giving you 78gb+25gb? (Assuming the cache is being filled at a constant 500mb/sec and cleared at 160mb/sec)
Yes it does, according to Linus, I didn't want to mention that incase it got confusing. So that is a significant transfer size I reckon.
I'm wondering if the 2TB QVO is good for RAID-0 video editing, specifically scratch disks in Adobe Premiere. I have 4 x 960 EVO 1TB in RAID-0 on a 2012 Mac Pro. The transfer speeds top out at around 550mbs
Your 2012 Mac Pro has 4 NVMe M.2 slots capable of RAID-0? I don't believe it. How many PCIe lanes exist on the motherboard?
No it has four SATA trays that support standard internal SSD's (which I use the 860 EVO's in). All my PCIe slots are full of video cards and storage I/O cards.
@DSOTM: 860 (SATA SSD) is not 960 (NVMe SSD). RAID-0 with SATA SSDs is a waste of effort for improving sequential R/W.
Haha he almost gave everyone a heart attack!
Thanks for the info. Can you please do similar comparison for 1TB Evo vs Qvo
It functions similar to the QVO, but instead of QLC it has TLC. Only looking at 1TB and 2TB EVO here.
The EVO reads at 560MB/s, so only 10MB/s faster than the QVO.
The 1TB EVO has SLC cache of 42GB and the 2TB has 78GB, the cache writes at 520MB/s. Same as the QVO.
The big difference is that when the SLC is full, the TLC is used and that runs at 500MB/s, only 20MB/s slower than SLC anyway. So amazingly fast at all times.
The write endurance of the 1TB EVO is 600TB and the 2TB is 1200TB. So that is close to double the QLC.
The performance of the SLC is limited by the SATA interface, that is when it is slapped into NVME, it really shines.
Now, I'd state that the EVO is overkill if all you are doing with it is playing games off it, get QVO for that. If you are doing lots of writes and deleting, go EVO.
The SLC cache size decreases to 6GB as the drive fills up.
Yes it does, right at the bottom I addressed that. I didn't mention size as it scales down, but pretty much the closer you get to full, the more your writes will be operating at 80 or 160MB/s.
Still, if you leave 10 to 15% of your drive empty, it will probably not be an issue. You are recommended not to fill any SSD also, but in a QLC SSD, you'll really notice the write performance hit.
When you say the QVO latency is "lower" I think you mean "higher" i.e. worse.
Yes I do, thanks. Trying to sneaky write at work.
Can I claim cashback if I buy four SSDs? I can't find any maximum limits on claiming in the T&C's.
No. It's in the T&C

No cash back on Futu right?
