AmorphousDiskMark is a Mac storage benchmarking app from Katsura Shareware with a user interface like that of the Windows app, CrystalDiskMark. Benchmark tests provide MB/s and IOPS results for a chosen target volume with controls over queue depth, test size, iterations and test intervals, as well as data choices (random or zero-fill), while tests include sequential 128KB and 1MB read/write, and random 4KB read/write. AmorphousDiskMark 2.5.2 is a free download for OS X 10.8 and later.
AmorphousMemoryMark is a Mac memory performance tester from Katsura Shareware with an interface similar to AmorphousDiskMark’s. Tests include sequential and random reads/writes at various sizes with various memory instructions, intervals, etc. Results are given in GB/s, and the app also provides details about the installed memory. AmorphousMemoryMark 1.0.2 is a free download for OS X 10.8 and later.
Atom Pro NVMe SSD is a compact, bus-powered, high-performance, SSD storage device from Glyph Production Technologies, Inc. that connects to a Thunderbolt 3 port on a computer or powered dock. Features include a “heat-dissipating” aluminum shell, “MIL-Standard 810F rating for shock, vibration, dust, and sand” and “read speeds up to 2,800 MB/s and write speeds reaching 2,450MB/s” with capacities of 500 GB, 1 TB or 2 TB.
Atom Pro NVMe SSD was priced at $299.95 / $449.95 for 500 GB / 1 TB when checked (at Amazon and elsewhere) or $999.95 for 2 TB.
(The Samsung X5 offers similar features, performance and pricing.)
Sensei is a new utility app from Cindori AB that adds to the capabilities of the company’s previous Trim Enabler and Disk Sensei Mac apps but only runs on macOS Catalina. Features include SSD Trim support, SMART reporting, performance testing, fan control, detailed Mac information and monitoring (temperature, CPU, GPU, battery, drives), an app uninstaller, disk “cleaning” and more.
Sensei 1.0.0, which is compatible only with macOS 10.15 Catalina, is priced at $59 for a permanent license or $29/year as a subscription. Upgrade discounts are available for owners of Trim Enabler and Disk Sensei.
MacInTouch Community discussions touch on the following topics (among others):
Rocket Nvme PCIe 4.0 [Amazon link] is an NVMe M.2 SSD from Sabrent that uses the new PCIe 4.0 standard for ultra-high performance, promising read/write speeds up to 5000/4400 MB/s with computer motherboards that support PCIe 4.0.
Note: In order to take advantage of these speeds, a PCIe Gen4 motherboard is REQUIRED. Otherwise it will be at pcie gen 3 speed at max of 3500MB/s. When installing any NVMe PCIe 4.0 SSD directly onto a PCIe Gen4 Motherboard a Heatsink is required to dissipate the heat generated by the drives extreme speed levels to avoid thermal throttling and maximize performance.
The Sabrent 1TB Rocket Nvme PCIe 4.0 M.2 2280 Internal SSD is backward compatible with PCIe 3.0. Using a Gen 3 PCIe motherboard will enable the user to reach speeds of up to 3400 MB/s (read) and 3000 MB/s (write).
Other features include SMART and Trim support, upgradable firmware, power management support (“APST / ASPM / L1.2”), and support for ONFi 2.3, ONFi 3.0, ONFi 3.2 and ONFi 4.0 interfaces.
Rocket Nvme PCIe 4.0 is sold via resellers in 500GB, 1TB and 2TB capacities ($119.98 to $369.99 when checked at Amazon).
Portable SSD T7 Touch is a newly announced successor to Samsung’s popular Portable SSD T5 [Amazon] promising even higher performance, while adding a new fingerprint scanner and data encryption hardware. (A version without fingerprint reader – “Portable SSD T7” – is planned for later release.)
The new T7 SSDs feature read/write performance up to 1,050/1000 MB/s in a similar compact aluminum enclosure (58g.) with a 10Gbps USB-C port (USB 3.1 Gen 2). Both USB-C and USB Type-A cables are included.
Portable SSD T7 Touch is list-priced at $129.99, $229.99, and $399.99 for 500GB, 1TB and 2TB capacities, due this month, while the version without fingerprint reading/encryption is due by mid-2020.
Trim Enabler is a Mac app from Oskar Groth (Cindori Software AB) that enables SSD Trim for better performance and longevity with solid-state drives. (Apple supports Trim for its own internal flash storage in modern Macs but doesn’t support third-party Trim without special overrides.) Features include Trim on/off switching, other optimization controls (Sudden Motion Sensor, Local Time Machine, Sleep Image, and Access Time logging), SMART-based information about drive health (with the option of installing a SMART driver for external drives), and a benchmarking utility.
Trim Enabler 4.1.3 is priced at $14.99 for OS X 10.9 and up, with a 14-day trial period and older versions available with support for earlier Macs. The latest version brings full support for macOS 10.14 and 10.15.
Sensei is a pending product for macOS Catalina that expands on the company’s previous Disk Sensei app (a more advanced alternative to Trim Enabler with a number of additional capabilities).
Turbo Boost Switcher is a Mac utility from from Rubén García Pérez (rugarciap.com) that lets you control Intel’s Turbo Boost mode to extend battery life, reduce CPU heating and otherwise tune the CPU for your particular needs. Other features include fan and temperature graphs, automatic enable/disable settings for individual apps, and the ability to change modes based on the presence of a battery charger, battery level, fan speed, and CPU load.
Turbo Boost Switcher Pro 2.9.1 is priced at $9.95 for Mac OS X 10.6 and up (including Catalina. A free version is available for download with limited features.
