Introduction |
Apacer’s ST250-300 is a well-balanced solid-state disk (SSD) drive with standard form factor and great performance. Designed in SATA 6 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.
ST250-300 utilizes 3D NAND for higher capacity up to 2TB and provides more power efficiency than 2D NAND. Appearing in JEDEC MO-300 mechanical dimensions, ST250-300 is believed to be the leading add-in storage solution for future host computing systems. Regarding reliability, ST250-300 is implemented with LDPC (Low Density Parity Check) ECC engine to extend SSD endurance and increase data reliability.
Data integrity can be assured at multiple points in the path to enable reliable delivery of data transfers with End-to-End Data Protection. 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™.

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™
Developed for read-intensive applications in particular, Smart Read Refresh™ is employed to make sure that during read operations, when the read operation threshold is reached, the data is refreshed by re-writing it to a different block for subsequent use
-
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™ combines both firmware and hardware mechanisms to ensure data integrity. Together, they allow more time for volatile data to be stored in the event of power loss.
-
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
The security standard trusted by the US government and many international security agencies. It’s an efficient and highly secure way of encrypting data to keep it safe from hackers and other bad actors.
-
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.
-
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.
