SandForce, opposed to other controllers, enforces a trick as they can write to the FLASH memory less then the competition needs to by using real time compression. However, all calculations on this matter debatable as usage differs and even things like how much free space you leave on your SSD can effect the drive.
Ocz vertex 3 firmware 2.5 full#
With a normal filled SSD and very heavy writing/usage of say 10GB data each day 365 days a year you'd be looking at roughly 22 full SSD write cycles per year, out of the 3000 (worst case scenario) available. Drive wearing protection will help you out greatly. Rumors are that the numbers for consumer grade 25nm NAND flash memory (as used on the SSD tested today) are even lower at 3000 program/erase cycles.īut granted, as drastic as that sounds, it's all relative as this lifespan will very likely last longer than any mechanical HDD. Personally I'm not at all a excited about the new 25nm NAND FLASH memories, the overall lifespan of the ICs has been reduced from 10.000 towards 5,000 program/erase cycles. As such it got a MTBF of 10 million hours (!) and the regular Vertex 3 will get the new (cost effective) 25nm NAND Flash memory with a lesser lifespan set at an MTBF of 2 Million hours.
Ocz vertex 3 firmware 2.5 pro#
No, the biggest difference in-between the regular Vertex 3 and the Vertex 3 PRO is the fact that the PRO makes use of Enterprise-Class MLC NAND Flash, yes. Now there's a 20% IOPS perf increase over the last generation product for the Vertex 3 but 30% for the PRO. Main controller differences, the regular Vertex does not have some enterprise features like power loss data protection & data recovery protection, it also offers 28% over-provisioning for optimal drive endurance and data protection & management hence the PRO version has less available storage space. The NAND FLASH partition the new SandForce 2281 assigned, opposed to the 2582 Controller used in the PRO assigned for multi-channel IO. OCZ places a NAND flash partition of 16 ICs onto one PCB. So the storage unit we'll be testing today is a 240GB version.
