4、Storage performance test

compared to the processor，Memory and storage are more important for daily office help，Guarantee the response speed of the whole machine，This HP EliteBook 600 is equipped with dual-channel 16GB DDR4 3200MHz memory + 512GB PCIe 3.0 Combination of SSDs。

use memory&Cache BenchMark tests memory，its read、Write、The copy speed is 39251MB/S respectively、41104MB/S、39214MB/S，Latency is 94ns，normal performance。

in our daily work，Not only need to open more documents、Web page，Also hang up the communication software in the background，Sometimes it is necessary to open a video conference at the same time, etc.，In short, these are very memory-intensive projects，16GB dual-channel large-capacity high-frequency memory avoids the situation of "exploding" memory，The whole machine can also ensure smoothness under high load，Not stuck。

The hard drive is a PM991a from Samsung，Capacity 512GB，PCIe3.0，The maximum sequential read and write speed is 3000MB/S+1580MB/S，It belongs to the mid-to-high-end PCIe 3.0 solid state，Boot speed、speed of opening files、The speed of file transfer is guaranteed。

5、Stability test

In addition to the performance pass，Stability is critical to business，To be able to run stably for a long time without errors, without blue screen and without crashing, so as not to affect the work process，We will use the oven to test its stability。

Conventional thin and light notebooks use a low-load Stress CPU for the oven test，But in order to test the stability of this EliteBook，We not only choose the Stress FPU with higher load for testing，A more severe Prime95 oven test was also conducted to verify the high stability of the HP EliteBook 600。

The first is the Stress FPU mode in the AIDA64 system stability test，Test time up to 1 hour，CPU power consumption is stable at around 22W，Full core frequency 2.6GHz，temperature 76 degrees。

Then the Prime95 test，This test is recognized as one of the roaster software that puts the most stress on the CPU，Its operating principle is to use the CPU to continuously perform the operation of Mersenne primes，Put the CPU to a very high load。Select the SmallFFTs test in Prime95 (mainly for the CPU part of the test，It will also perform a certain filling test on the CPU cache)，Test time is 1 hour，CPU power consumption 24.5W，Full core frequency 2.6GHz，temperature 81 degrees。

in the oven，Whether it is StressFPU or Prime95，full power consumption、Temperature and frequency are quite stable，no blue screen、crash、restart etc.，enough to see its high stability，Of course there's nothing to worry about in this regard。

6、Endurance test

The ability to have such a battery life is due to three aspects，The first is the large-capacity battery，The HP EliteBook 600 is equipped with a 3-cell 51.3Whr battery，Provides higher power，Then there is the big power generation CPU，AMD Ryzen 5000 series processors have excellent power control capabilities，Full guarantee for battery life；

Finally, another big power generation player that is often overlooked - the screen， HP EliteBook 645 In addition to the comprehensive quality of the screen, the，Screen power consumption is only 1W，Greatly reduces the power consumption of this part。The combination of all parts of the whole machine creates this battery life monster，Provide adequate protection for business people working abroad。

But the power can resist，also when it runs out，Charging speed is also critical，EliteBook600 supports fast charging technology，Officials say it can be charged in half an hour，in my test，It took 40 minutes to charge from 3% to 53% (bright screen + Wi-Fi connection)。

7、Worry-free service

HP's commercial notebooks were never "sell and forget" products，HP provides a fairly complete service for its commercial notebooks during the life of the product，It can be done through the built-in Huiwuyou and Huimanu。
