Frequently asked questions
What are the random I/O performance specifications of the Intel 320 Series SSDSA2BW300G3?
The drive delivers up to 39,500 IOPS for random 4KB reads and 23,000 IOPS for random 4KB writes. These performance metrics significantly exceed mechanical hard drive capabilities (typically 100-200 IOPS), making the 320 Series suitable for transactional databases, virtualization hosts, and multi-user server environments where concurrent I/O demand is high.
Does the Intel 320 Series support full-disk encryption, and what standard is used?
Yes, the SSDSA2BW300G3 includes full-disk AES-128 encryption to protect data at rest. This hardware-based encryption operates transparently without degrading performance, meeting compliance requirements for HIPAA, PCI-DSS, and other regulated industries handling sensitive customer or financial data.
What is the form factor and interface type, and which systems is it compatible with?
The drive is a 2.5-inch form factor with SATA II (3Gb/s) interface. It fits directly into 2.5-inch bays in laptops, desktops, and servers. Compatible with any system supporting SATA II, including Dell PowerEdge, HP ProLiant, IBM System x servers, and standard consumer notebooks and desktops manufactured between 2010–2015.
What NAND technology and reliability rating does this SSD use?
The 320 Series uses Intel's 25nm Multi-Level Cell (MLC) NAND flash memory, balancing performance with endurance for mixed workloads. It carries a 1,200,000-hour MTBF (Mean Time Between Failures) rating, indicating enterprise-grade reliability suitable for 24/7 continuous operation in data center and server environments.
How does the Intel 320 Series compare to mechanical hard drives for server storage?
The 320 Series delivers 39,500 IOPS versus 100–200 IOPS from 15K RPM SAS drives, reducing query latency by 95%+. Boot times drop from 3–5 minutes to 30–60 seconds. Power consumption is 2–3W versus 8–12W for mechanical drives, lowering cooling costs. Trade-off: 300GB capacity is smaller than typical 600GB–1.2TB SAS drives, so it suits OS/application tiers rather than bulk data storage.
What power-loss protection features does the SSDSA2BW300G3 include?
The drive features enhanced power-loss management that protects in-flight data during unexpected power failures, preventing corruption of file systems and databases. This is critical in server environments where unplanned shutdowns can occur, ensuring data integrity and reducing recovery time after power restoration.
Is the Intel 320 Series still supported, and what is its lifecycle status?
The 320 Series reached end-of-life status around 2015–2016 and is no longer manufactured by Intel. It is available only as refurbished or pull inventory from resellers. While no longer under active support, the drive remains functional and is widely used in legacy systems. For new deployments, Intel's 545s or 760p series are recommended alternatives.
