The most special feature of Intel's Intel Optane SSD 905P solid-state drive for enterprise-class and high-endurance users is that it is equipped with 3D XPoint non-volatile memory particles, compared to the general AOD516 solid-state drive products equipped with NAND flash memory particles. , the main feature can not only greatly reduce the SSD access latency, but also the write tolerance is up to PB level specifications, so that the performance of the SSD in terms of 4K access performance and service life can be significantly improved.

The Intel Optane SSD 905P solid-state hard drive will launch 380GB~1.5TB and other capacity specifications for users with different storage needs, of which the 380GB capacity adopts the M.2 22110 interface design, and the 480GB specification adopts the 15mm -ic/" title="15mm model. ">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model"> 15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm- ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/ " title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title="15mm model">15mm-ic/" title ="15mm model">15mm-ic/" title="15mm model">15mm 2.5-inch U.2 transmission interface, as for the 960GB and 1.5TB capacity versions, 15mm 2.5-inch U.2 and HHHF PCIex4 interface can be selected. Although the interface and capacity specifications of these Intel Optane SSD 905P are different, the transmission bandwidth specifications are all designed by NVMe PCIe3.0x4, and all can achieve 2600/2200MB/s sequential read and write and 575K/550K IOPS 4K random Read and write performance. However, the most special point is that in terms of write tolerance specifications, even the smallest 380GB M.2 22110 version can reach 6.93PB, and the 1.5TB version can reach 27.37PB. .

The Intel Optane SSD 905P borrowed this time is a 2.5-inch U.2 transmission interface version of the boxed version of 480GB.

On the back of the box, you can see that this 480GB U.2 version of Intel Optane SSD 905P will also come with an M.2 2280 adapter cable, so that general motherboards can also be used for adapter.

Open the top cover of the outer box to see the solid-state drive directly, and there are some included accessories in the space below.

The accessories included in the package are mainly paper manuals, fixing screws and U.2 to M.2 adapter cables.

The included U.2 to M.2 adapter cable needs to be connected to another set of SATA power supply when actually using it.

The M.2 circuit board connected to the online is designed with a 2280 size specification, which is convenient for users to use with general motherboards.

The 480GB U.2 version of the Intel Optane SSD 905P hard drive enclosure is made of aluminum metal, and the front and rear sides have a columnar design that increases the surface area, allowing the hard drive to have better heat dissipation.

The U.2 transmission interface on the hard disk, the actual transmission bandwidth can reach NVMe PCIe3.0x4.

The thickness of this hard drive is 15mm, and there are fixed screw holes on both sides.

Since the hard drive cover uses a thick metal shell, the actual weight will reach about 150 grams.

●Intel Optane SSD 905P 480GB 2.5-inch U.2 SSD transmission performance test

After reading the specifications of this Intel Optane SSD 905P, let's actually test the performance of the hard drive! Below are the platform components for this test, for your reference.

◎Processor: Intel Core i9-9900K

◎Motherboard: ASUS ROG MAXIMUS XI EXTREME

◎Memory: G.Skill FLAREX DDR4-3200 8GBx2

◎Power supply: Antec 850W

◎Operating system: Windows 10 64 bit

When using the hard disk for the first time, you can find the hard disk and format it in the disk management interface. The actual free space after formatting is about 447GB.

The operating temperature of this 480GB U.2 version of the Intel Optane SSD 905P is about 48°C in normal state, which is slightly higher than that of ordinary SSDs.

◆AS SSD Benchmak test

When actually using the AS SSD Benchmak software test, the sequential read and write performance of the 480GB Intel Optane SSD 905P solid state drive can reach approximately 1956.59MB/s and 2230.49MB/s, and the 4K random read and write performance can reach 166.65MB/s and 153.62MB/s. The final result has a total score of 6998 points.

In the 4K-64Thrd test project, the read and write performance can reach 619410iops and 601917ops.

◆ATTO Benchmak test

When actually using ATTO software to test, the read and write performance of the 480GB Intel Optane SSD 905P solid state drive can reach about 2780MB/s and 2460MB/s.

◆CrystalDiskMark test

When the CrystalDiskMark software is set to the random data option, the read and write performance of the 480GB Intel Optane SSD 905P solid state drive in sequential read and write projects can reach approximately 2777.7MB/s and 2454.5MB/s, and the read and write performance in 4K projects is approximately It can reach 231.4MB/s and 207.1MB/s.

When the data option is set to 0Fill mode, the read and write performance of the 480GB Intel Optane SSD 905P solid state drive in sequential read and write projects is about 2778.2MB/s and 2455.3MB/s, and the read and write performance in 4K projects can reach about 231.4 MB/s vs 207.8MB/s.

◆TxBENCH test

●Trial summary

From various test results, it can be seen that this 480GB U.2 version Intel Optane SSD 905P solid state drive is not the fastest in sequential read and write, but its performance in 4K random read and write is better than that of general SATA or SSD solid state drives with M.2 NVMe interface are obviously 3 to 4 times faster in performance, coupled with their own write tolerance specifications of up to 8.76PB, I believe that for some servers that will have a large number of access times in a short period of time In terms of application, it can effectively improve the access delay and reduce the cost of hardware replacement. However, in terms of the general use environment, it is actually difficult to feel the difference between the Intel Optane SSD 905P solid state drive and the general SSD, and only the 480GB U.2 version The Intel Optane SSD 905P solid state drive will cost $599, which is about 3825 yuan in RMB. I believe that many players have been discouraged when they see the price!
