Industrial SSD: ST250-M242 |
Apacer’s ST250-M242 is a well-balanced solid-state disk (SSD) drive with standard form factor and great performance. Designed in SATA 6.0 Gb/s interface, the SSD is able to deliver exceptional read/write speed, making it the ideal companion for heavy-loading industrial or server operations.
ST250-M242 utilizes 3D NAND for higher capacity up to 1TB and provides more power efficiency than 2D NAND. Regarding reliability, ST250-M242 is implemented with LDPC (Low Density Parity Check) ECC engine to extend SSD endurance and increase data reliability while reading raw data inside a flash chip. In addition, the drive comes with various implementations including powerful hardware ECC engine, power saving modes, wear leveling, flash block management, S.M.A.R.T., TRIM, and DataDefender.
In terms of security, with End-to-End Data Protection, data integrity can be assured at multiple points in the path to enable reliable delivery of data transfers.

End-to-end Data Protection
This technology ensures that whenever data moves from the host to the controller or from the controller to DRAM or NAND flash, error checking is applied. In some cases, error correction will also be part of the circuit.
-
Smart Read Refresh™
Apacer's Smart Read Refresh™ technology is designed to mitigate read disturbances in NAND Flash memory.
-
Page Mapping
Page mapping is an advanced flash management technology and can be considered the ideal solution for industrial applications to increase random access speed and improve SSD lifespan, reduce block erase frequency, and achieve optimized performance.
-
Over-provisioning
Apacer’s SSDs support over-provisioning, which sets aside a certain portion of the physical capacity of the memory to carry out garbage collection, wear-leveling and bad block management. The result is a longer operating lifetime.
-
S.M.A.R.T.
S.M.A.R.T. is a self-monitoring system that provides indicators of drive health as well as potential disk problems. It serves as a warning for users from unscheduled downtime by monitoring and displaying critical drive information.
-
DataDefender™
Apacer's DataDefender™ technology is designed to protect SSDs from data loss or corruption in a sudden power outage.
-
DEVSLP
Device Sleep is a feature that allows SATA devices to enter a low power mode by designating pin P3 as DEVSLP signal with an aim to reducing power consumption.
-
AES 256-bit Encryption
Apacer takes security to the next level with hardware-based encryption.
-
ATA Secure Erase
When this command is given, an SSD will reset all its storage cells to empty, releasing trapped electrons and restoring the drive to its original state. This operation completely wipes data from the drive.
-
Sidefill
Apacer’s Sidefill technology strengthens the connections between solder joints and their board, making them more robust and vibration-resistant. It also allows for heat dissipation to offset thermal damage.
-
CoreAnalyzer2
CoreAnalyzer2 is an exclusive, analytic data-behavior technology implemented on our SSD products. Featuring collecting and analyzing data of customers' host system, it can help our customers analyze their usage behavior so they can choose the best-suited.
-
SSDWidget 2.0
Apacer SSDWidget 2.0 is a comprehensive disk monitoring and maintaining utility. Designed with the concepts of S.M.A.R.T., SSDWidget2.0 can monitor SSD’s health-related information and provide SSD status for SSD lifetime monitoring and workload analysis.
