WD_BLACK P40 Recreation Drive USB 3.2 Gen 2×2 Transportable SSD Overview: Balanced Storage

The What’s Subsequent Western Digital occasion again in Could 2022 noticed the introduction of recent merchandise within the WD_BLACK lineup. On the moveable SSD (PSSD) entrance, the WD_BLACK P40 Recreation Drive SSD augmented the corporate’s robust set of choices within the gaming market. As a complement to the favored WD_BLACK P50 Recreation Drive SSD, the brand new PSSD retained the USB 3.2 Gen 2×2 (20 Gbps) hyperlink whereas including RGB lighting to the case.

The P40 was launched at a a lot cheaper price level in comparison with the P50. As a way to obtain the cheaper price level and make the P40 a mid-range providing, the corporate has reduce some corners whereas nonetheless promoting the drive as a 2GBps-class one. The evaluation under presents an in depth analysis of the WD_BLCK P40 Recreation Drive SSD and compares it towards a bunch of different PSSDs in the identical capability class. Our evaluation reveals use-cases the place the P40 does make sense to make use of with out spending far more for the premium-class P50.

Introduction

Exterior bus-powered storage units have grown each in storage capability in addition to speeds over the past decade. Because of fast developments in flash expertise (together with the appearance of 3D NAND and NVMe) in addition to quicker host interfaces (resembling Thunderbolt 3 and USB 3.x), we now have palm-sized flash-based storage units able to delivering 3GBps+ speeds. Whereas these speeds may be achieved with Thunderbolt, mass-market units should depend on USB. Inside the USB ecosystem, USB 3.2 Gen 2 (10 Gbps) is quick changing into the entry degree for thumb drives and moveable SSDs. Premium units sporting the USB 3.2 Gen 2×2 (20 Gbps) interface have been making it to the market over the past couple of years, with host assist in desktops and different computing platforms beginning to decide up. Broadly talking, there are 5 distinct efficiency ranges on this market:

• 2GBps+ drives with Thunderbolt 3 or USB4, utilizing NVMe SSDs
• 2GBps drives with USB 3.2 Gen 2×2, utilizing NVMe SSDs or direct USB flash drive (UFD) controllers
• 1GBps drives with USB 3.2 Gen 2, utilizing NVMe SSDs or direct UFD controllers
• 500MBps drives with USB 3.2 Gen 1 (or, Gen 2, in some circumstances), utilizing SATA SSDs
• Sub-400MBps drives with USB 3.2 Gen 1, utilizing UFD controllers

The PSSD we’re at the moment – the WD_BLACK P40 Recreation Drive – belongs to the second class within the above record. Western Digital’s WD_BLACK lineup of merchandise targets the gaming market, with deal with efficiency numbers in addition to industrial design / RGB lighting. The corporate has additionally been utilizing the lineup to carry new expertise to the market – such because the WD_BLACK P50 Recreation Drive SSD again in 2019. It was one of many first 20 Gbps PSSDs to hit the market when it was launched. This allowed the corporate to cost a premium for the high-performance product that continues to this present day. In an try and increase the lineup with a mid-range providing, WD launched the P40 Recreation Drive SSD with very comparable specs (as much as 2000 MBps) earlier this 12 months at a a lot cheaper price level.

The WD_BLACK P40 Recreation Drive SSD retains the economic design and look of its premium sibling, whereas being barely extra compact. One of many key updates appreciated by the goal market is the addition of RGB lighting (controllable through WD’s dashboard software program) to the case. As an alternative of supplying two separate cables, WD is offering a single Kind-C to Kind-C cable with an connected Kind-C to Kind-A adapter.

The strong aluminum steel casing lends a rugged look to the drive, and lays to relaxation any potential thermal issues throughout operation.

CrystalDiskInfo gives a fast overview of the PSSD as seen by the host system. The P40 assist S.M.A.R.T passthrough and TRIM, as proven within the screenshot under. In comparison with the DRAM-equipped SN750E used within the P50, WD is utilizing a DRAM-less SN560E within the P40. The price-savings translate to the cheaper price on the P40 in comparison with the P50.

The desk under presents a comparative view of the specs of the totally different storage bridges offered on this evaluation.

Previous to wanting on the benchmark numbers, energy consumption, and thermal answer effectiveness, an outline of the testbed setup and analysis methodology is offered.

Testbed Setup and Analysis Methodology

Direct-attached storage units are evaluated utilizing the Quartz Canyon NUC (primarily, the Xeon / ECC model of the Ghost Canyon NUC) configured with 2x 16GB DDR4-2667 ECC SODIMMs and a PCIe 3.0 x4 NVMe SSD – the IM2P33E8 1TB from ADATA.

Probably the most engaging side of the Quartz Canyon NUC is the presence of two PCIe slots (electrically, x16 and x4) for add-in playing cards. Within the absence of a discrete GPU – for which there is no such thing as a want in a DAS testbed – each slots can be found. The truth is, we additionally added a spare SanDisk Excessive PRO M.2 NVMe SSD to the CPU direct-attached M.2 22110 slot within the baseboard with a purpose to keep away from DMI bottlenecks when evaluating Thunderbolt 3 units. This nonetheless permits for 2 add-in playing cards working at x8 (x16 electrical) and x4 (x4 electrical). For the reason that Quartz Canyon NUC does not have a local USB 3.2 Gen 2×2 port, Silverstone’s SST-ECU06 add-in card was put in within the x4 slot. All non-Thunderbolt units are examined utilizing the Kind-C port enabled by the SST-ECU06.

The specs of the testbed are summarized within the desk under:

The testbed {hardware} is just one phase of the analysis. Over the previous couple of years, the everyday direct-attached storage workloads for reminiscence playing cards have additionally developed. Excessive bit-rate 4K movies at 60fps have develop into fairly widespread, and 8K movies are beginning to make an look. Recreation set up sizes have additionally grown steadily even in moveable sport consoles, due to excessive decision textures and paintings. Conserving these in thoughts, our analysis scheme for direct-attached storage units entails a number of workloads that are described intimately within the corresponding sections.

• Artificial workloads utilizing CrystalDiskMark and ATTO
• Actual-world entry traces utilizing PCMark 10’s storage benchmark
• Customized robocopy workloads reflective of typical DAS utilization
• Sequential write stress take a look at

Within the subsequent part, we have now an outline of the efficiency of the WD_BLACK P40 Recreation Drive SSD in these benchmarks. Previous to offering concluding remarks, we have now some observations on the machine’s energy consumption numbers and thermal answer additionally.
