Intel’s next generation 530-series SSDs are about to be launched, probably next week. The new drives are based on 20nm MLC and the same LSI Sandforce SF-2281 controller used in previous Intel SSDs.
The 530 series will eventually replace all 520 and 525 series drives. It will come in three form factors, the standard 2.5-inch 7mm, mSATA and NGFF M2. There’s also a generous choice of capacities, 80GB, 180GB, 240GB and 360GB for mSATA and NGFF M2 drives. The far bigger 2.5-inch will have a choice of 180GB, 240GB, 360GB and 480GB drives.
There is still no word on performance, but the new series should end up noticeably faster than 520/525 drives.
I own quite a few SSD drives. They really aren't all the same. Most use the Sanforce controllers. The controllers need the firmware upgraded from time to time. This is where you really see the differences between them. Some of the Corsair SSD's need a huge work around in order to put the new firmware on it. OCZ is much better but requires backups and specialized Linux boot disks to run the updates
Intel drives are simply the best. They have simply superior software that monitors the drive and can apply firmware updates within Windows. It monitors the drives health and runs TRIM on a regular basis. I am running a pair in RAID stripped. Flawless thus far.
One thing about SSD drives that you need to keep in mind is that performance really suffers when its nearly full. Sometimes its best to backup the drive and then copy the data back over. If it's a Windows C drive it's often best to give a fresh install of Windows, especially if the C drive is very full.
The 530 looks like a great drive, but just about any other Intel SSD drive is also great.. The one thing that would make a huge difference would be if Intel were to start using PCIe slots instead of SATA3.
