1. Exterior Overview
The Samsung 9100 PRO 8TB SSD is available in both standard and heatsink versions， with their exteriors being largely consistent with the previously reviewed 4TB model.
The front label of the standard version mirrors the design of the 4TB model， complete with product model， S/N code， capacity， and other essential information. Notably， due to the increased number of NAND FLASH chips， the operating current has been raised from 2.9A for the 4TB version to 3.5A. For prolonged full-load operation， it is recommended to use the motherboard’s built-in M.2 heatsink or opt for the more efficient heatsink version.
Upon removing the front label， the PCB layout reveals one PCIe 5.0 controller chip， one LPDDR4X DRAM dedicated cache chip， and two NAND FLASH chips on the front. The PCB also features an abundance of surface-mounted capacitors and resistors， ensuring overall stable operation.
The proprietary controller chip， codenamed “Presto，” is built using a 5nm process and a low-power architecture. It features a nickel-plated coating， coupled with an integrated Dynamic Thermal Guard (DTG) mechanism and copper foil thermal conductive labels/enveloping heatsinks， effectively ensuring stable data transmission during extended use. The accompanying LPDDR4X DRAM dedicated cache chip capacity has also been increased to 8GB， further enhancing I/O efficiency at a ratio of 1GB per 1TB.
The core components are Samsung’s eighth-generation V-NAND TLC original chips， which， along with the two chips on the back， constitute the 8TB capacity.
Unlike the 1-4TB versions， the Samsung 9100 PRO 8TB utilizes a double-sided chip design， with two NAND FLASH memory chips also present on the PCB’s reverse side. Copper foil thermal conductive labels are applied to the areas corresponding to the controller chip and the DRAM dedicated cache.
The heatsink version’s appearance is much like the 4TB model. The enveloping heatsink features a matte black spray-painted finish， with CNC precision-machined bright edges. Its four grooves significantly increase the heat dissipation area， adorned with the Samsung brand logo and “Solid State Drive” text， presenting a grand visual effect with a strong sense of overall integration.
Due to the double-sided chip design of the PCB， the heatsink’s height has increased from 8.8mm on the 1-4TB versions to 11.25mm. This height is balanced to ensure compatibility with various devices and maintain effective heat dissipation without interfering with graphics cards or CPU coolers. However， on some high-end motherboards， you might need to remove the bottom thermal pad of the M.2 SSD slot to install it. Additionally， it has been optimized for the depth of the hard drive bays in Sony PlayStation 5 gaming consoles， preventing it from interfering with the cover.
The heatsink on the back of the label sticker is essentially the same as the standard version.

3. Benchmark Testing
For this testing， we selected high-end platforms featuring the AMD Ryzen 9 and Intel 14th Gen Core i9 processors. Here are the detailed configurations.
As a capacity upgrade product， the Samsung 9100 PRO 8TB boasts nominal performance identical to the 4TB version: sequential read/write speeds of 14800MB/s and 13400MB/s， respectively， and random performance of 2200K IOPS and 2600K IOPS. CrystalDiskMark tests confirmed sequential read and write speeds of 14827.77MB/s and 13389.99MB/s， which are well within the claimed specifications.
The TxBench test results， used for comparison， show sequential read and write speeds for the Samsung 9100 PRO 8TB reaching 14062.64MB/s and 13628MB/s， essentially achieving “full power PCIe 5.0” levels. For random performance， as measured by Crystal Disk Mark， the drive reached 2150K IOPS and 1996K IOPS. This variance can be attributed to differences in the queue depth and thread settings of the testing software， as well as the demanding requirements of PCIe 5.0 on CPU quality and motherboard electrical performance.
The doubling of SSD capacity not only allows for storing more files but also theoretically doubles the SLC cache space for the Samsung 9100 PRO 8TB， thanks to Samsung’s proprietary TurboWrite 2.0 technology， significantly enhancing write performance. In the professional software IOmeter， with a 128KB data block and QD32 queue， after a 40-minute test， the sustained write speed remained stable at 13100-13400MB/s initially. After 53 seconds， the SLC cache was exhausted， and direct flash write speeds dropped to 1500-1900MB/s. Calculations indicate an SLC cache of up to 2TB when the drive is empty， meaning the Samsung 9100 PRO 8TB will be significantly more efficient for data-intensive industries like film and television production and AI applications.
After the controller’s Trim operation for 1 hour， we tested the Samsung 9100 PRO 8TB’s random write performance using IOmeter with 4KB data blocks and QD32 queues for 45 minutes. The test graph clearly demonstrates the Samsung 9100 PRO’s formidable strength， with the dense range falling between 2450000-247000 IOPS. Not only was there no significant fluctuation throughout the test， but the dispersion was also very low， indicating that random write performance remains a strong suit for this product.
Despite the doubling of NAND FLASH chip count， the power consumption increase for the Samsung 9100 PRO 8TB is not substantial. In smartmontools， five preset modes are visible. During full-speed operation， PS0-PS2 modes show a maximum power consumption of 9.3W， while the shallow sleep PS3 mode can drop to as low as 0.05W， and the deep sleep PS4 mode reduces it further to 0.007W. This indicates that the product offers an excellent balance between performance and energy consumption， making it suitable for gaming laptops without prematurely draining the battery.
To test thermal performance， we conducted a 20-minute IOmeter 128KB sequential write test， pushing the Samsung 9100 PRO heatsink version 8TB into a fully loaded state. The temperature curve shows a peak temperature of 83℃. Although slightly higher than the 4TB version， it did not trigger the Dynamic Thermal Guard (DTG) mechanism. Therefore， for heavy workload scenarios， the heatsink version is strongly recommended.
