One side of the PCB houses two NAND packages (code BW29F4T08GMLBE), while the other side of the PCB houses the Maxio MAS0902A-B2C controller and two other NAND packages.

Maxio MAS0902A-B2C is a very compact (9mm x 9mm) 4-channel controller with no DRAM design, using two compute cores, supporting up to 4TB 2D MLC/TLC 3D MLC/TLC or QLC NAND via Toggle3.0/ONFi4 . 0 interface. It uses Maxio's own Agile ECC 2 error correction and WriteBooster 2 SLC caching technology.

For testing purposes, HDDerase V4 wipes all drives and resets them to factory settings. We try to use free or readily available programs and some real-world tests so that you can compare our findings to your own system.

This is a good way to gauge potential upgrade benefits.

All our results were achieved by running the test five times for each configuration, which ensures that any glitches are eliminated from the results. Confirm that Trim is running by entering fsutil behavior query disabledeletenotify at the command line. A response of disabledeletenotify =0 confirms that TRIM is active.

CrystalDiskMark is a useful benchmark for measuring the theoretical performance levels of hard drives and SSDs. We are testing with versions 6 and 8.

Atto Disk Benchmark 4.0

  CrystalDiskMark softwareCrystalDiskMark

In the CrystalDiskMark QD32 single-threaded benchmark run, read and write scores of 312MB/s and 296MB/s, respectively, put the Acer SA100 in the middle of the results table. We can confirm the official Sequential 560MB/s read performance, the test score is 562MBs, the official write data is 508MB/s, and the best test result is 514MB/s.

We can confirm these official Sequential data with CrystalDiskMark 8 again. Looking at the two benchmark results screens, the Maxio MAS0902A-B2C controller in the SA100 does not appear to have a preference for the type of data required.

CrystalDISkMark 8 – Peak Performance Profile

 Peak Performance ProfileAcer SA100 2.5

Acer cites the 1.92TB drive's 4K random performance as up to 76,000 IOPS for reads and 77,000 IOPS for writes. Using the peak performance profile to test the drive, the drive produced the best 74,906 IOPS for reads and 68,087 IOPS for writes, both lower than the official figures.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system performance using various transfer sizes and read and write test lengths. There are several options for customizing your performance measurements, including queue depth, overlapped I/O, and even a compare mode with the option to run continuously.

Use the ATTO Disk Benchmark to test any manufacturer's RAID controllers, storage controllers, host adapters, hard drives and SSD drives, and note that ATTO products will always provide the highest level of performance for your storage.

The ATTO Disk Benchmark

In the ATTO benchmark, we couldn't reach the official sequential maximums for reads (560MB/s) or writes (508MB/s), with benchmark scores of 537MB/s and 478MB/s, respectively.

AS SSD is an excellent free tool designed for benchmarking solid state drives. It performs a series of sequential read and write tests, as well as random read and write tests with sequential access times on a portion of the drive. AS SSD includes a set of benchmarks with various file mode algorithms, but it's hard to judge accurate performance numbers.

SA100 random read and write test

The Acer SA100 performed poorly on the demanding AS SSD benchmark, although write performance was much stronger than read.

IOMeter is another open source synthetic benchmarking tool capable of simulating various loads on hard disk drive and solid state drive technologies.

AS SSD benchmark

We tested using the random read and write 4k test as shown above. There are many ways to measure the IOPS performance of SSDs, so our results sometimes differ from the ratings quoted by manufacturers. We do test all drives in exactly the same way, so the results are directly comparable.

IOPS performance of SSDs

The Acer SA100 read speeds NAND controller

The Acer SA100 has read speeds up to 76,000 IOPS and write speeds of up to 77,000 IOPS. Unfortunately, our tests couldn't come close to these numbers. The best read we saw was 59,144 IOPS, while the best write 61,186 IOPS was slightly closer to the official figure.

We also used CrystalDiskMark 8 with 1 to 4 threads to test the random performance of the drive at lower queue depths (QD1 – QD8, where most everyday workloads occur).

Between QDs 1 and 2 using single threads, the drive's performance slowly climbed from 11,655 IOPS (47MB/s) to 13,164 IOPS (60MB/s). After QD2, performance climbed sharply until the end of the test run (QD8) with a final test figure of 58,999 IOPS.

Using 2, 3, and 4 threads, the drive produced 61,570 IOPS (252MB/s), 73,785 IOPS (302MB/s), and 75,667 IOPS (309MB/s) at a QD of 8, respectively.

For long-term performance stability testing, we set the drive to run a 20-minute 4K random test with 30% writes, 70% reads split, and a queue depth of 256 across the disk. The 1.92TB Acer SA100 tested an average IOPS of 15,340 with a performance stability of 73%.

The PCMark 10 Full System Drive Benchmark uses a wide-ranging set of real-world traces from popular applications and common tasks to fully test the performance of the fastest modern drives. The benchmark is designed to measure the performance of fast system drives using the SATA bus at the low end and devices connected via PCI Express at the high end.

The goal of the benchmark is to demonstrate meaningful real-world performance differences between fast storage technologies such as SATA, NVMe, and Intel Optane. The full system drive benchmark uses 23 traces, each run 3 times. It usually takes an hour to run.

2.5-inch SATA SSDs

The Acer SA100 handled our real-life file transfers without too many problems, although it did struggle to read 100GB data files.

Acer , in partnership with Chinese chip maker BIWIN , has entered the SSD storage market, providing drives for the home and professional markets. You may not have heard of BIWIN (BIWIN Storage Technology Company Limited), but the company was founded in 2010 and designs, manufactures and sells consumer flash memory and memory for several well-known computer brands. Acer's new storage portfolio includes2.5-inch SATA SSDs (SA100, RE100), M.2 SATA (RE100) and M.2 PCIe Gen3 NVMe (FA100) drives.

The entry-level SA100 comes in five capacities; 120GB, 240GB, 480GB, 960GB and the flagship model, the 1.92TB drive we're reviewing here. At the heart of the SA100 is the Maxio MAS0902A-B2C controller. The controller is a 4-channel IC without DRAM, measuring only 9mm x 9mm, making it one of the most compact NAND controllers available.

The read and write speeds of the 1.92TB SA100 are as high as 560MB/s and 508MB/s, respectively. Using the ATTO benchmark, the best we saw was 537MB/s for reads and 478MB/s for writes, both lower than the official figures. However, using the CrystalDiskMark benchmark, we can confirm that the two official figures have an optimal read speed of 562MB/s and a write speed of 514MB/s.

As for random 4K performance, the SA100 tops out at 76,000 IOPS for read and 77,000 IOPS for write. We couldn't hit the max data during testing, and the best we saw was 75,667 IOPS (QD8) for reads, 71,721 IOPS for writes, and 4 QDs.
