Sabrent Rocket 4 Plus M.2 SSD and PS5 Heatsink Review

Sabrent is among the first to market an SSD intended for the PlayStation 5. It is distinguished by the presence of a heat sink specifically designed for the reserved slot of the Sony console and by leading performance, Necessarily. A few weeks ago, we took advantage of Sony’s release of new firmware to take stock of the mounting of an additional internal SSD on the PlayStation 5. Sony opted for a different operating on Microsoft’s Xbox X Series. On PS5, it is necessary to disassemble (a little) the console to access the reserved space and mount, a bit like on a PC, the new SSD. Now, PlayStation 5 allows you to add an additional M.2 NVMe SSD in addition to the one present inside the console in order to greatly expand the storage memory. Now there is an SSD that could help to allow the console to cool more efficiently. We are talking about the Sabrent Rocket 4 Plus SSD and PS5 Heatsink just for the additional SSD.

Sabrent has been a certainty for several years now in the world of SSD memories for the assembly of our PCs. First the classic Rocket, then followed by Rocket 4.0, and now by Rocket 4 Plus: Sabrent’s product range is expanding! The Rocket 4 Plus is one of the fastest Nvme 4.0 SSDs in the world, if not the fastest. It is certainly the most performing we have ever tested. The Sabrent Rocket 4 Plus is clearly a Nvme SSD with PCI Express 4.0 support and therefore requires a system equipped with this technology to take advantage of its advantages. If we did not use this SSD on a motherboard and processor with PCI Express 4.0 we would limit the speed of our drive to 3400 MB / s for reading and 3000 MB / s for writing. Our drive is based on memories L96 TLC NAND FLASH latest generation, which allow you to achieve read speeds of 7100 MB / s write and 6600 MB / S.

You’ve heard right, yes, 7100 MB / s read and 6600 MB / s write! Really impressive numbers when compared with Nvme SSDs from competing brands that, despite being fast, stop at much less. The Sabrent Rocket 4 Plus is available in 1TB, 2TB, and 4TB versions. Needless to say, however, the prices are very high: just over $159.99 for the 1TB, $309.99 for the 2 TB version, and $749.99 for the 4 TB version. In our case, we will test the 2TB variant.

Unpackaging

The SSD combo is delivered by Sabrent in very high quality, The Sabrent Rocket 4 Plus is delivered as usual in a small cardboard box that is sealed in plastic foil. A sticker here indicates that an Acronis True Image software license is included. This is a great plus that you rarely get from another manufacturer. Unfortunately, the software is only designed for Windows systems. In the paper packaging, there is a box that appears to be made of aluminum and anodized in a copper color. The box feels really high quality and is similar to the boxes of the other Sabrent NVMe solid-state modules.

In the box, you will find paper instructions and underneath the Sabrent Rocket 4 Plus NVMe SSM, which is held by a foam insert. The Rocket 4 PLUS is protected from the side by foam and held in the correct position. SSD includes 16-page operating or installation instructions and additional surface protection.

The Heatsink is also delivered in a small cardboard box, in the box, Heatsink is held by foam and you will find paper instructions. The contents of the “Sabrent M.2 NVMe PS5 Heatsink” are the heatsink body (thermal pad is already attached) and the Phillips screwdriver No. 0. In addition to the 6-page declaration of incorporation, the PS5 Heatsink also has a small screwdriver that is suitable for the two screws of the “hanging nose”.

Both instructions have been kept very small, but explain the installation step by step to every inexperienced gamer – everyone else is welcome to take a look as they provide additional information that is very amazing. This certainly includes more efficient cooling compared to conventional heat sinks when used with the PlayStation 5. But the guarantee of 5 years also calms our inner spirit.

Sabrent Rocket 4 Plus M.2 SSD Details

The SSD is an M.2 2280 module measuring 22 x 80 x 1.5 mm and weighing 9 g. What surprises many is that the disc in the base has no massive cooling, there is only a thin aluminum plate on the chips and according to the manufacturer, it is enough to cool the disc with an overview. However, you can buy an improved model with a large cooler relying on a Heatpipe tube and it has a surcharge of about $29.99. Of course, if your motherboard is equipped with this heatsink on the M.2 slot, definitely use it. The disk will then have lower temperatures, which of course contributes to its longer life (applies to the controller, on the contrary, NAND chips prefer higher temperatures). Of course, I’ll see in today’s review how integrated onboard cooling affects disk temperatures during load.

  • Transfer rates up to 7,100 MB / s for reading and 6,600 MB / s for writing
  • Up to 700,000 IOPS
  • Disk life 1400TB overwritten data.
  • 5-year warranty

We will also learn from the manufacturer’s website that this model line uses the Phison E18 controller, thanks to which it can provide such high transmission speeds. Regarding memory chips, there are 96-layer TLC chips from Micron. The disc is covered by a standard five-year warranty. The Sabrent Rocket 4 Plus also uses the NVMe 1.4 standard and requires four PCIe Gen4 lanes. Of course, the Sabrent Rocket 4 Plus can also be operated on PCIe Gen. 3 systems, since downward compatibility is fully guaranteed here, but the full performance is simply not achieved.

This is because PCIe Gen. 3 x4 lanes create a maximum (theoretical) bandwidth of 3,938 MB / s. In contrast, the theoretical limit of PCIe Gen. 4 x 4 lanes is 7,877 MB / s, and the Sabrent Rocket 4 Plus is very close to this limit on paper. When it comes to writing, most models are further removed from this magical limit, but it’s not just about sequential writing and reading; rather, most operating systems work with thousands of small files and a lot happens in small chunks that randomly appear somewhere on the NVMe SSM are distributed. This means that the sequential values are only particularly important for copying large files, but everyday life rather consists of a mix of large and a disproportionately large number of small files.

A special feature of the Sabrent NVMe SSDs is the copper cooling plate attached to the top. Where most manufacturers only place a paper sticker, the Sabrent Rocket 4 Plus has a thin copper plate with some information printed on it. This serves as a heat spreader, with the aim of distributing and dissipating heat from the chips more homogeneously. Especially if you don’t have a smart cooler on it, it’s a nice extra and feels valuable. When you pull it off, you immediately notice that it is copper, as the metal bends and behaves accordingly tough.

Under the special copper sticker, we find four TLC NAND Flashes, which are named IA7BG64AIA (D2106F-P06NVKG). During our research, we were able to find little information about memory. The chips are to be manufactured by Micron and each has 256 GB of storage capacity per chip. This is 3D TLC NAND, which consists of 96 layers. With the 2 TB and 4 TB variants, the back of the Sabrent Rocket 4 Plus NVMe is also equipped accordingly.

The choice of controller falls on the powerful PS5018-E18-41 from Phison. This is manufactured by TSMC in a 12nm process and can manage a maximum of 8 TB NAND flash. The controller uses 8 channels and achieves a maximum bandwidth of 1,600 MT / s per channel, which would result in a mathematical maximum value of 12,800, which in turn would only be achievable with PCIe Gen 5. The real data from Phison set the maximum limit of 7,400 MB / s for sequential reading and 7,000 MB / s for sequential writing. The IOPS is 1,000K for random read and 1,000K for random write. The consumption of the controller is given as 3.0 watts. The work is done by a 32-bit ARM Cortex R5 (3 CPUs).

The nice thing about this is that the Phison controller already supports hardware encryption with AES 128/256 bit, SHA 160/256/512, RSA 4096 as well as firmware options TCG, Opal 2.0, Pyrite, Sanitize, and Crypto Erase. However, Sabrent only advertises the features: SMART and TRIM, ONFi 2.3, ONFi 3.0, ONFi 3.2, and ONFi 4.0 interface, as well as advanced wear-leveling, bad block management, error correction code, and over-provision.

This is supported by an SK Hynix H5AN8G6NCJ-RVKC-0317v DDR4 SDRAM. There is no official SK Hynix website here and the information that can be found on the chip shows it to be a 512 Mx16 memory chip.

Sabrent M.2 NVMe PS5 Heatsink Details

The Sabrent M.2 NVMe PS5 Heatsink is an aluminum heatsink with a copper accent on black paint. An oblique air slit is also provided on the surface to promote heat dissipation. Sabrent M.2 NVMe PS5 Heatsink looks like a thin aluminum plate with a thickness of about several mm when viewed from above, but the part in contact with the M.2 SSD is raised by about 10 mm, and it is thick. It is a heat sink. A soft thermal pad with a thickness of about 3.0 mm that easily deforms according to the unevenness of the SSD is attached as standard. As you can see on the PS5 official support page, a heatsink is required for the M.2 SSD used to add storage to the PS5.

There are some illustrations, but I think the last one on the official support page when installing the double-sided heatsink is the easiest to understand. It is OK if you do not think difficult and simply suppress the two requirements of ” up to 8.0 mm above the M.2 SSD board ” and ” up to 2.45 mm below the M.2 SSD board “.

The Sabrent M.2 NVMe PS5 Heatsink is designed to be compatible with the expansion slot cover built into the PlayStation 5 and fits perfectly into the expansion slot. In the standard configuration of PS5, the heatsink attached to the SSD dissipates heat in the expansion slot and exhausts it with a negative pressure structure, but the Sabrent M.2 NVMe PS5 Heatsink has a metal cover of the expansion slot. Since it is a heat sink that is used as a replacement, it has a cooling structure that dissipates heat directly to the outside of the expansion slot and diffuses it with the cooling fan next to it. As for the weight, which is an index of heat dissipation buffer performance, the SSD is about 9g, the Sabrent M.2 NVMe PS5 Heatsink is 60g.

Benchmark Test in PC

The test system is based on a PCIe 4.0 compliant setup, with a Gigabyte X570 Aorus Xtreme and the AMD Ryzen™ 9 5900X CPU. In benchmarking, we use tools to determine performance. We ran several tests and benchmarks on our Sabrent Rocket 4 Plus: the applications used were CrystalDiskMark, ATTO Disk Benchmark, and Anvil’s Storage Utilities.

CrystalDiskMark

The first testing benchmark is CrystalDiskMark, a classic among disk performance benchmark applications. The setting of our program includes tests both in writing and also in reading, first sequential and then random. Both the first two sequential tests on 1 MB files (both reading and writing) were performed on a single thread, first with a queue of 8 and subsequently with a queue equal to 1.

The random tests on files of the size of 4KB follow the same trend, only that the queue in the first case amounts to 32 and then again to 1. The tests run 5 times and the transfer time is 1GB overall. The result is surprising: the Sabrent touches 7000 MB / s in sequential reading and reaches 6100 MB / s in writing. Data that, as we will see, with long queues on ATTO, will grow further in writing, confirming those declared by the company.

ATTO Disk Benchmark

We carry out the second test on ATTO Disk Benchmark: another super versatile application for the performance evaluation of disks. This tool allows us to establish the length of the transfer (in our case only 256 MB) and the size of the files to be transferred. The program is very precise and we particularly like ATTO, since it gives a broader view of the behavior of the disks than the already seen CrystalDisk.

Also in this case the Sabrent Rocket 4 Plus confirms what we would have expected: the minimum write speed on standard size files never drops below 6.35 GB / s. Reading is clearly even faster. All tests are very consistent with each other, even with file sizes quite distant from each other such as 48 MB and 256 KB.

Anvil’s Storage Utilities

Anvil’s Storage Utilities is more of a benchmarking program than a test program. Yet this gives us certain values that we had not yet seen so far: latencies. We also find data without units of measurement, which are simply scores. As I had previously mentioned fact Anvil is a tool to test as much as the benchmark.

The results therefore in this case cannot be of much use if we do not compare them with some other device. We also have at our disposal the response times in latency or the I / O operations in addition to the classic speed in MB / s.

Rocket Control Panel

Sabrent SSDs come with two drive management utilities: the Rocket Control Panel and the Sector Size Changer. As the name implies, the second will be used to change the size of the drive Sector; the first software, on the other hand, is the control center of all the vital parameters of the Sabrent SSDs, with the ability to monitor the temperature, the status of the SMART, update the firmware and check the health of the SSD.

Another program that you can install to disk is Acronis True Image and SSC Software. The former is very suitable, for example, for making backups of your disk in the form of a 1: 1 image, or, for example, migrating an old disk on which you have an operating system to a new one just purchased from Sabrent. The latter is then used to change the size of sectors on the disk, etc. For most customers, the most useful will be Control Panel or Acronis. In any case, it is a very above-standard package of programs, most manufacturers give a maximum of one program to the discs, some do not give any to the discs, so Sabrent is such a small unique in this respect.

Sabrent PS5 Heatsink Installation & Test

The first thing to do, however, was the installation, which immediately raised certain concerns. Usually, the heatsink connects so tightly to a thermal pad and the SSD that trying to separate them will probably result in the destruction of the SSD. Sabrent, therefore, uses a weaker adhesive connection, with which the heat sink (cover) can be detached from the SSD without much effort. That has to be the case since the SSD is also fixed with a screw beforehand and the heat sink (cover) could no longer be removed if the connection was too strong.

The installation was done in no time, basically even easier than with a stand-alone heatsink, since you didn’t have to align the SSD first. Simply plug it into the SSD slot, tighten the screw, put the heatsink on it, screw it tight and you’re done. Everything is in its place. To do this, Sabrent has therefore machined a small heatsink that must obviously be placed on the SSD during assembly. Still, to stand out from the competition and score extra points, Sabrent has designed a heatsink that perfectly matches the shape of the slot provided by Sony. In fact, the heatsink is thicker than most of its competitors and you can set aside the small plate intended to close the slot.

After we installed the Sabrent Rocket 4 Plus according to the instructions, including the heat sink, the PlayStation 5 runs a speed test on the SSD. It should be noted in advance that we did not check the specified read and write speeds of 7000 MB/s and 6600 MB/s on the PC since we installed it in the PlayStation 5. According to Sony Interactive Entertainment’s announcement, even if the sustained read and write speeds are higher than the PS5’s official standard, not all performance characteristics will match the PS5 console’s built-in Solid State Drive. Our PlayStation 5 reports a read speed of 6,557.139 MB/s.

Crucial to the Sabrent Combo is the heat sink, which was specially developed from high-quality CNC-milled aluminum. Instead of just cramming a heatsink onto the SSD that just traps the heat in the metal cover, Sabrent designed a heatsink to replace the native PS5 cover. This allows for better cooling with the native fan as well as a larger heatsink. As a result, the Sabrent PS5 heatsink uses the system twice and thus more effectively.

Better Cooling Solution

Now to the really exciting topic. Does Sabrent keep the promise of having a better cooling solution, even if you bypass the idea of the Sony engineers? Various test scenarios were used for this, different games, temperature measurement during operation, as well as at different positions, namely on the escaping airflow and the controller itself. The results may surprise me on the one hand but are quite logical to understand.

The biggest difference can be seen, and as expected, in the SSD slot and on the controller itself, where a temperature difference of 5 to 6 degrees can be seen in the reading process under load in gaming. Logically, since the waste heat is no longer trapped. However, the difference decreases to less than 1 degree during the copy process from the internal SSD to the additional storage, where an equally constant write process takes place and the SSD runs at its best. The differences are even more apparent when starting the SSD, where the larger Sabrent heatsink was also able to dissipate and dissipate heat faster. In general, however, the temperature with all memories gradually increases the longer the PS5 is in operation.

Things are a bit different with the Airflow, where almost identical results are achieved during operation. Measurements were taken on the outside of the heatsink and the fan, which sucks in the exhaust air directly. In this respect, there is no negative impact to be feared here if the waste heat is conducted directly into the housing of the PS5. At the same time, the structure on top of the Sabrent heatsink ensures that it is cooled down again by the active airflow of the PS5. This was particularly evident in the writing process under full load. Really clever solution.

Of course, it cannot be ruled out that different results will come out from game to game or when comparing other storage systems with Sabrent’s. In our case, all things being equal, Sabrent fully delivers on its promise.

The Sabrent Heatsink not only stands out for keeping the promise but also for being the SSD and heatsink solution currently specially developed for the PS5. An absolute unique selling point, which is well thought out and does an excellent job. In a nutshell, the Sabrent Heatsink does not ensure the best and most efficient heat dissipation to date, but also uses the internal airflow for itself and thus adapts perfectly to the design of the PS5. Another advantage: the SSD memory can be detached from the heat sink without any problems.

Conclusion

With the PS5 SSD combo, Sabrent gives us the best combination of an SSD and a heat sink. The Sabrent Rocket 4 Plus is available in sizes from 500 GB, 1 TB to 8 TB – PlayStation 5 only supports 4 TB, 8 TB is coming soon – offering every gamer the desired size, from beginners to frequent gamers. The price of the PS5 Rocket Combo is also very attractive and the PS5 Heatsink for around 20 dollars can be described as more humane. The PS5 gamer gets what is probably the best cooling system with an enormous read and write speed on the PlayStation 5. The Sabrent Rocket 4 Plus combo clearly outperforms the competition and will quickly become the favorite of all PlayStation 5 gamers. An outstanding product, because someone has finally thought about it and doesn’t just offer a PC SSD for the PS5.

After the detailed test of the Sabrent Rocket 4 Plus, it becomes clear that the solid-state module is definitely one of the best in the high-end segment. The built-in technology in the form of the Phison PS5018-E18 controller and Micron 3D NAND memory delivers very good performance values. The sequential read rates of 7,000 MB/s and sequential write rates of 5,300 MB/s advertised by Sabrent were achieved and exceeded in the test. When reading or writing many small files, the values look different, but when copying a 200 GB Steam games folder, the Rocket 4 PLUS comes up to 2.07 GB/s.

The Sabrent Rocket 4 Plus has some unique selling points that the competition does not offer. This includes, for example, the particularly high-quality and chic outer packaging in the form of an aluminum box with a copper look. The Acronis True Image license that you get with the purchase of the solid-state module is also a great extra. In addition, there is the copper plate, which is attached to the NAND chips and the controller and thus ensures better heat conduction. The overall package is well above the standard of the competition.
