Go here for a full listing of ADATA SSDs – and make certain the one you purchase is TRIM-enabled. Go here to access ADATA's free SSD ToolBox software (Sorry, it only runs with ADATA SSDs!).While heavy industrial-grade users may need to run the TRIM command more often, as a general rule of thumb for personal PC users, you can run the TRIM command using ADATA's free ToolBox software about once a month for good measure. The application is easy to download, install and run, ( see here) and it only takes a short time to run. No matter which your case, when using a TRIM-enabled ADATA SSD, you can manually optimize your SSD's performance by using ADATA's free Software ToolBox. While some systems come off the shelf with proprietary or built-in TRIM applications of their own, surprisingly there are a few out there which still don't offer TRIM optimization. For personal users such as those folks using an SSD for their laptop, performance degradation will likely occur rather slowly over time. This usually occurs in environments of heavy use – for example where your SSDs are being used in write-intensive applications in data centers. A Solution: TRIMĭepending on several factors such as in what manner your applications write (such as sequentially or randomly) to your SSD, as well as how often you read/write to your SSD, performance can degrade noticeably as you fully access and rack up actual read/write hours on your disk. What's not mentioned above is that this condition happens over time and with relatively heavy use. For magnetic disks this is no different from writing an empty sector, but because of how some SSDs function at the lowest level, an overwrite produces significant overhead compared to writing data into an empty page, potentially crippling write performance." ( Wikipedia ) While this often enables undelete tools to recover files from electromechanical hard disks, despite the files being reported as "deleted" by the operating system, it also means that when the operating system later performs a write operation to one of the sectors, which it considers free space, it effectively becomes an overwrite operation from the point of view of the storage medium. Since a common SSD has no knowledge of the file system structures, including the list of unused blocks/sectors, the storage medium remains unaware that the blocks have become available. Contrary to, for example, an overwrite operation, a delete will not involve a physical write to the sectors that contain the data. As our friends in the wiki world explain it:īecause of the way that many file systems handle delete operations, by flagging data blocks as "not in use", storage media (SSDs, but also traditional hard drives) generally do not know which sectors/pages are truly in use and which can be considered free space. Unlike hard disk drives, those blocks of SSD storage which are no longer actively being used are treated differently than from the time we previously used "spinning disk" HDDs. However, with all the benefits that SSDs bring, they are still susceptible to weaknesses inherent to their design. On the business side, they provide lower latency – a measurable thumbs-up for the performance of time-sensitive applications commonly seen in commercial and industrial applications. SSDs provide the convenience of high speed data access to desktop consumers running IO-intensive applications. SSDs offer certain benefits over conventional (spinning disk) HDDs. As they come down in price, more and more private consumers and commercial enterprises are adopting solid state disks (SSD) as a primary form of data storage.
