The disk itself is an obsolete product, and it appears to be a brand new spare part from Lenovo, with a considerable quantity. Several major sellers on the large ship JS are offering it, but there doesn't seem to be anything particularly boast-worthy about the product itself. I genuinely don't find any outstanding features, so it can be considered a rather ordinary and unremarkable supplementary test.

Currently on Taobao/Xianyu, the price for 1T is around 280 yuan, and for 2T it's around 600 yuan.

Although it comes with outer packaging, it is of the industrial packaging type, so it is still shipped wrapped in foam and the like. In addition to the hard drive, a heat dissipation sleeve and a delivery note are included.

The outer packaging is covered with various codes such as SN codes, and the place of origin is Taiwan.

There is an anti-tamper sticker at the top left and bottom right, making it clear whether it is brand new or not ('I opened it').

The back side fully reveals the solid-state drive, but neither the solid-state drive nor the casing clearly indicate the capacity, which needs to be determined through SN codes and the like.

Regarding the casing, one shell can accommodate four types of M.2 hard drives with sizes 2230/2242/2280/22110. However, from my impression, it seems that Intel's enterprise level does not have 2242 and 2230 sizes.

The 2260 size is really not used by anyone~~~

On the front of the hard drive, 'based on the main controller', you can see there is also a Lenovo sticker, with one sticker on each side. The back side is for internal identification by Intel, while the front sticker is for OEM identification.

The Lenovo sticker indicates the product's capacity, model, and SN number, and even the interface type is marked.On the back of the product, there is an Intel sticker that indicates the place of origin, voltage, and other information.

In terms of the main controller, it is developed by Intel itself, with little information disclosed, and the specifications are unknown.

The cache consists of one chip on the front and two on the back, with the silkscreen markings of H5AN8G8NCJRVKC for two chips and H5AN4G4NBJRTFC for one chip. The former is DDR4 1GB at 2666 MHz with C19 timing, and the latter is DDR4 512MB at 2133 MHz with C15 timing, totaling 2.5GB of cache.

Regarding the chips, there are four 29F02T2ANCTHI and two 29F04T2ANCTHI chips, all belonging to Intel's 3D64 chips, which are relatively early 64-layer 3D TLC chips. There is no difference in the manufacturing process, only in the individual capacities of the chips.

The silkscreen number 29F02T2ANCTHI corresponds to a single chip with a capacity of 256GB, and the silkscreen information 29F04T2ANCTHI corresponds to a single chip with a capacity of 512GB. Thus, they collectively form a 2TB capacity. So, although it may be hard to believe, the fact is that the Intel P4511 2TB version indeed has no over-provisioning (OP) space, which is a rare situation for enterprise-level hard drives with full capacity.

For testing, the built-in DIMM.2 slot of the M15E is still used, paired with the motherboard's built-in cooling shroud.

The downside of this shroud is that it is not perfectly centered, leaving a small part exposed, but the issue is minor and does not significantly affect usage.

In terms of configuration, it is still the set of 139 configurations, with XMP not enabled and the default 4800 completed the test, using the motherboard's built-in DIMM.2-2 interface for testing, and covering the shroud.Let's take a look at the official data first. This is an old product from 2018, as indicated by the NAND date and it was still in production in 2021. Regardless of TBW (Total Bytes Written), endurance rating, or sequential read/write performance, the specifications are quite ordinary with no real standout features, making it a typical storage drive.

The hard drive has a temperature limit set at 73 degrees Celsius, which is relatively low.

The CDI (CrystalDiskInfo) inspection shows some simple items, essentially confirming that it is a brand-new hard drive. Additionally, the temperatures displayed by the software are quite low, indicating that the measured temperature points are likely near the NAND, which is not typically very hot. In fact, even within the 22110 form factor, it's considered quite cool. There will be more detailed tests to follow, as the low temperatures are quite realistic.

The CDM (CDM Benchmark) results are also in line with the official claims, but the 4K read speed is relatively slow. Of course, for a storage drive, this is not a significant issue. Since Intel's enterprise-grade SSDs do not have an SLC (Single-Level Cell) cache design, this drive's performance is pretty much as expected.

The Txbench results are similar, but the 4K performance is even lower here, which is an old tradition with Intel.

For the full drive write test, the speed remained consistently at 1.2 GB/s throughout the process.

In terms of temperature, a thermal imaging was taken during the full drive write, and the hottest spot was found above the controller at 49 degrees Celsius. When the drive is idle with the heatsink cover, the outer shell temperature is only in the 30s, and the software shows a temperature of around 26 degrees Celsius. Overall, the temperature is very low, and the cooling effect of ASUS's heatsink cover is quite average, so it can be said that the drive's temperature performance is good.

However, after removing the heatsink cover, the controller temperature at idle can reach over 70 degrees Celsius, and the NAND chip area at the back is around 40 degrees Celsius. Overall, considering the drive with the heatsink cover, the temperature is still very low, especially for a 22110-sized drive.

The reason for this situation is quite simple: the drive itself does not generate much heat, but the heat is concentrated, mostly around the controller, which leads to higher temperatures (similar to the concept of pressure).

Nevertheless, it is still recommended to use the heatsink cover, as the controller might not be able to withstand the heat otherwise, and 73 degrees Celsius is precisely the temperature limit.Just looking at this temperature is quite refreshing; the room temperature is around 24 degrees Celsius. The far left is the CD6 with a fan, the middle is the KC3000 with a medium cover, and the right is the P4511. Who wouldn't be impressed by these temperatures?

The PCMark 10 primary storage benchmark test score is 2193 points, with a storage bandwidth of 344.08MB/s and an access time of 75 microseconds.

The PCMark 10 complete system drive benchmark test score is 1276 points, with a storage bandwidth of 211.35MB/s and an access time of 136 microseconds. In terms of scores, it's not much higher than SATA...

The 3DMark storage benchmark test score is 1268 points, with a storage bandwidth of 223.99MB/s and an average access time of 146 microseconds.

The P4511 2TB performs well, surpassing the baseline hard drive PE4010 and is also stronger than the PE6010 2TB. It is currently the best-performing hard drive in the 3.0 2TB enterprise category.

This drive is somewhat unexpectedly ranked quite well on the list, surpassing many consumer-grade PCI-e 4.0 non-volatile drives. It mainly relies on its strong response speed (which is considered an optimization direction for some enterprise drives) to elevate its overall ranking.

Ranking list link: [https://www.kdocs.cn/l/cclAK4hwJHvw](https://www.kdocs.cn/l/cclAK4hwJHvw)Initially, the parameters seemed quite average, but the final temperature performance turned out to be quite good. Overall, this drive is still very suitable as a storage drive today, or it can serve adequately as a cache or storage drive for a NAS system [since not many internal networks can reach 2G/s]. The drive itself has a TBW of around 2P, which is quite decent. As the testing progressed, my impression of this drive improved, and I would recommend it.

In terms of the drive itself, it loses points for being too old, both in terms of the NVMe specification and the process technology of the NAND particles. With NVMe 2.0 solid-state drives almost on the market, version 1.2 just doesn't cut it anymore. Therefore, for this drive, we can only hope for it to serve as a low-temperature, durable, and secure storage drive.
