Klevv Genuine G560 2 TB

[W1zzard]

The Klevv Genuine G560 is a PCI-Express 5.0 M.2 solid-state-drive that can reach transfer rates of over 14 GB/s. Unlike other drives it comes with a decent fanless heatsink preinstalled. In our testing we're not only looking at raw performance, but also thermals and throttling.

"Holy thermal throttling Batman!"

Guess that's the price to pay for speed and high power use in a tiny size.

Gotta hand it to them though, the whole disk fill speed is the fastest average - @W1zzard is that number obtained from the drive being actively cooled or using the stock heatsink and just passive blow by from CPU cooler?

 

[W1zzard]

is that number obtained from the drive being actively cooled

it's actively cooled, to remove the "cooling" variable from the test, which is focused on the SLC cache behavior

Is anyone really going to be that interested with those absurd prices? I thought it was 2018 for a moment.

Still doesn’t seem to be a point in Gen 5 drives for most people. Impressive numbers, don’t get me wrong, but the thermals, price and limited-to-none real world benefits kinda make it a meh product.

Speaking of the SN850X. Its absent from TPU reviews.

AS for the Klevv. I thought the white part of the heatsink was a little silly. They should have kept it finned for the extra surface area for cooling and slapped their brand logo/model number somewhere else. Its very style over substance.

Im not sure if the pads are also a little overly thick which could be making thermal transfer worse. The heatsink could be better. Price is also pretty insane. Maybe you could pick up other gen 5 SSDs without the heatsink then slap a cheap big ol' Thermalright on it and get better thermals.

Oh dear.

Normally the only things that are labelled genuine are not, in fact, genuine.

Well as usual Klevv has made another very nice looking piece of hardware....

Unfortunately, the guys over in marketing/retailing had one too many tokes off the ole crack pipe while figuring out how to price it, which essentially GUARANTEES it will be DOA for most folks, especially when we can get an almost as fast & good looking WD 850X for ~50% less than this one....

To whit, I just picked up 20x 4TB 850X's from da Zon for $239 each, and 8x 8TB's for $522 each, right after xmas....my clients are gonna get some nice Happy New Years presents for sure

Agreed, faster and faster sequential performance is completely wasted on your average consumer, this is exactly why I have been hoping and praying for an all-SLC drive to be created for the consumer market (they already exist in enterprise).

These all-SLC drives get very close to the performance of optane in low queue depth random reads and writes, exactly where it matters for an actually discernable performance improvement. In the image below, you can see the Performance of an all SLC DapuStor Xlenstor2 800GB (represented by the "D:") and the Optane P5800X 800GB (represented by the "O:") in a 1GB and 8GB test:

4K random IOPS:

Now, compare the all SLC drive to the synthetic numbers from the 5.0 Klevv drive in this review and ask yourself which drive you would prefer to have your OS on....

 

[eldon_magi]

i wish they would focus on increasing IOPS instead of sequential read and write speeds, that very seldom are needed.

This.

A 2GB/s drive with 100K Q1T1 IOPS is more useful to consumers than 15GB/s drive with 25K Q1T1 IOPS.

I have an SN550 2TB (Gen3 x2 limited to 1800MB/s) at the office running as an OS disk and it's indistinguishable in real-world use from drives that have 8x the sequential performance. Copying large amounts of data to is fast too because even when it runs out of SLC cache, it's still writing at almost 1GB/s - vastly superior to just about any popular QLC drive on sale today. Those turds often struggle to keep up with spinning rust once their cache is full.

Thanks for the review. It's nice to see 4GiB low power ddr ram soldered on a nvme again.

I have the kc3000 2tb drive. I most likely bought that particular drive becuase of some review in the past.

Those pcie 5.0 drives are just not delivering. When I look at that chart I can not see pcie 5.0 at all. 5%? 10%? difference to the kc3000 2tb?

Capacity: 2000 GB (1863 GB usable)

Is this the usual size? Or is this lower as usual?

This is the standard. 2048 GB -> 2000 GB, few other drives are 2048 GB -> 2048 GB (no additional overprovisioning)

 

[eldon_magi]

a 333GB or 666GB SLC drive with 2x or 3x the IOPS for $75 or $150 would be awesome for a separate OS drive.

Overkill, but so is a 4090 - and some people pay for those.

Are there any tests to see how TLC -> SLC change applies to real application and tasks? Is it really worth it or at least noticeable?

Actually most modern TLC drives should act like SLC all the time due to the SLC cache, which is almost never exhausted

There are people who want a drive like this. Premium drive is premium. The price might be high but the performance is outstanding. And the thermal issue is easily solved with active cooling via a fan blowing directly on the drive.

I have the kc3000 2tb drive. I most likely bought that particular drive becuase of some review in the past.

I have this same model too (with Micron nand). As far as I know, it's the only consumer SSD with 1024-2048-4096 GB rated capacity. Even the closest relative, the Fury Renegade, is 1-2-4 TB.

This is the standard. 2048 GB -> 2000 GB, few other drives are 2048 GB -> 2048 GB (no additional overprovisioning)

No "additional" OP, yes. But we can't say with any certainty how much total OP there is. The raw flash chip capacity is at least 20% larger than the rated capacity of, say, "1 terabit". You can calculate it by multiplying all the relevant numbers in the TPU database. Some of that is defective from the fab, some is for internal use (FW, FTL, other metadata, LDPC, caches, whatever), some is OP.

A 2GB/s drive with 100K Q1T1 IOPS is more useful to consumers than 15GB/s drive with 25K Q1T1 IOPS.

But the exotic SLC Dapustor Xi-stor only yields 157 MB/s while the best TLC SSDs reach around 110 MB/s (Q1 4K reads). Yeah, something worth salivating over, but not to the point of dehydration.
