Intel vs iStorage SSD Specs
Interface speed
The Intel D3-S4510 uses a SATA 6Gb/s interface, which caps sequential read speeds at 560 MB/s and write speeds at 510 MB/s. This is the standard limit for enterprise SATA drives. The iStorage diskAshur2 uses a USB 3.2 interface. Its sequential read speed reaches up to 361 MB/s, and write speed reaches up to 358 MB/s. While USB 3.2 can support much higher speeds, the iStorage drive’s actual performance is lower than the Intel drive’s SATA ceiling. The Intel drive offers faster throughput for its class. The iStorage drive is slower in raw transfer rates.
Form factor
You need to consider where you will install the drive. The Intel D3-S4510 is a 2.5-inch drive with dimensions of 2.5 inches by 1.5 inches by 2.5 inches. It weighs 3.2 ounces. This form factor is designed for internal installation in servers and workstations. The iStorage diskAshur2 is a portable drive. Its dimensions are 4.72 inches by 3.15 inches by 0.59 inches. It weighs 7.62 ounces. The iStorage drive is larger and heavier. It is built to be carried in a bag. The Intel drive is built to stay inside a chassis. The Intel drive fits standard server bays. The iStorage drive fits no internal bay.
Storage capacity
Capacity determines how much data you can store. The Intel D3-S4510 offers 1.92TB of storage. This is a common size for enterprise read-intensive workloads. The iStorage diskAshur2 offers 1TB of storage. The Intel drive provides nearly double the capacity of the iStorage drive. If you need to store large databases or extensive virtualization images, the Intel drive holds more data. The iStorage drive holds less. The iStorage brand does offer other capacities in variations, but this specific model is limited to 1TB. The Intel model is fixed at 1.92TB.
Security features
Both drives include hardware encryption. The Intel D3-S4510 uses AES 256-bit encryption. It also includes power loss protection and end-to-end data protection. These features ensure data integrity in 24/7 data center environments. The iStorage diskAshur2 uses AES-XTS 256-bit hardware encryption. It requires a 7-15 digit PIN to authenticate. It includes a Common Criteria EAL 5+ certified secure microprocessor. The iStorage drive is designed for portability and theft protection. The Intel drive is designed for server reliability and compliance. Both offer strong encryption, but the iStorage drive adds PIN-based access control for physical security.
NAND type
The type of NAND flash affects endurance and performance. The Intel D3-S4510 uses 64-layer Intel 3D TLC NAND. It is rated for 1 DWPD (Drive Writes Per Day). This endurance rating is suitable for read-intensive enterprise workloads. The iStorage diskAshur2 does not list its NAND type in the provided data. We cannot compare the specific layer count or endurance rating for the iStorage drive. The Intel drive has a known endurance spec. The iStorage drive lacks this public specification. The Intel drive is transparent about its NAND technology.
