Laptops, SSD, Raid 5 and trim

[Deandre]

The TRIM can delegate part of the management of the wear of the flash memory to the operating system. Until now, even if the SSD was compatible with this technology, its use on a RAID meant that the feature was disabled at the expense of performance. Can anybody explain me more. Thanks in advance.

Today that seems ancient history since Intel has put online a new version of its drivers RST (Rapid Storage Technology) . And good news: this version supports stamped 9.6.0.1014 TRIM even through architecture RAID (except RAID 5 ) .In short, it is possible to use SSD RAID mounted and still benefit from TRIM, provided they meet the following conditions :
- Use SSD natively support the TRIM
- use an Intel compatible motherboards
- install the drivers 9.6.0.1014 SLI
- activate the TRIM
Once thee conditions are met , TRIM should be usable on your machine even if SSDs were configured as RAID .

Intel to remedy thus providing an update that will activate the TRIM for SSD 's ICH RAID 10 or 11, provided that all holders of the cluster are able to manage and they are not configured in RAID 5. The TRIM control , which aims to prevent the performance of a DSS to deteriorate over time , proved far failed when several records were assembled into a RAID . Intel has released a new driver for motherboards equipped with a chipset ICH ICH 10 or 11 which aims to fill this gap .

More and more SSD manage TRIM and they will handle all in the near future. operating system side , there are only Windows Seven which is the norm and ATA8 runs natively TRIM. There is then no need to run a scan disk manually to take advantage of TRIM everything is done automatically in Windows 7.

With TRIM, a DSS erases data and holds positions in the disk where data have been deleted to gain speed . The physical deletion of data is slower , but unlike a conventional hard disk , the SSD need to erase the disk physically located before they can rewrite it. Thus, thanks to TRIM, the Rewriting is faster and its speed remains stable over time.

Second update for this short . After conflicting statements from Intel, it appears that TRIM is indeed supported by piles of Intel SSD in RAID 0 and RAID 1 with Intel drivers Rapid Storage Technology 9.6. However, it is not using the Intel SSD Toolbox more efficient , but the TRIM built-in native to Windows 7.
