Closer Look: ADATA S511 SSD

SSDs are quickly gaining popularity because they work equally well in PC, Linux, or Apple Mac computers. Likewise, they install into both desktop and notebook platforms without modification. For this article Benchmark Reviews is testing the 120GB ADATA S511 Solid State Drive, which is specified to reach speeds of 550 MB/s for sequential reads and 510 MB/s sequential writes. The AS511S3-120GM-C model we've received for testing is built using the SandForce SF-2281 SSD controller and Intel-Micron NAND flash components.

ADATA offers three capacities for their S511 series of solid state drives: 60GB, 120GB, and 240GB. Performance specifications increase with capacity, as a result of larger integrated buffer. All of the ADATA S511 SSDs models share the same part numbers, with a capacity designator trailing the end: AS511S3-120GM-C stands for 120GB. With respect to ADATA's S511 series, the 240GB version is expected to be the most popular of the two capacities because it offers the best performance specifications.

The ADATA S511 SSD is best suited for performance-orientated personal computers, but could also work well for SOHO computer workstation systems. SandForce SF-2200 series SSDs have been designed with a focus on high-performance operational and data transfer speeds, and includes 256-bit encrypted data protection and improved NAND wear-leveling through their proprietary DuraWrite technology. Although ADATA S511-series SSDs do not offer an integrated USB Mini-B port, which appeared on some early-generation SSDs, the retail market offers several different 2.5" SATA enclosures that utilize the SuperSpeed USB-3.0 standard for high-performance portable file transfers.

ADATA recognizes that once installed, the SSD will be hidden away from view inside a notebook computer or desktop workstation, so they've remained conservative towards the design of their solid state drive appearance. Each half of the drive enclosure is given an anodized black aluminum grain finish, which does not show fingerprints or smudges like a gloss surface would. A glossy label is attached to the top of the SSD enclosure, denoting model and capacity.

Standard 2.5" drive bay mounting points are pre-drilled and threaded into the ADATA SSD chassis, which allows for quick upgrade or addition into any existing notebook and other compact computer system. Fortunately, ADATA also includes a 3.5" to 2.5" tray adapter with this kit, so the S511 will easily install into desktop computers. The mounting positions matched up to the drive bracket on my notebook computer, and after only a few minutes I was booting from a restored Windows 7 System Image without a hitch.

Unlike most Hard Disk Drive (HDD) storage products, SSDs are nearly impervious to impact damage and do not require (or benefit from) any kind of special vibration dampening or shock-proof enclosures. ADATA utilizes a standard two-piece metal enclosure for their S511-series SSDs, which reveals the internal components after removing four small counter-sunk screws located along the sides of this solid state drive. The seam along the side is covered with a 'Warranty Void' label, which ADATA attaches to warn consumers against taking apart their product. By removing the SSD cover it will also remove your consumer protection with it, but Benchmark Reviews takes the risk for you and reveals the internal components in our next section.

If you're familiar with previous-generation ADATA storage products, you'll notice that looks for the S511-series haven't changed beyond the descriptive product decal. While its outward appearance is similar to many other solid state drives, the functionality and value packaged inside are considerably unique. Now that you're acquainted with the basic exterior features of this SSD, it's time to peek inside the metal enclosure and inspect the SandForce SF-2281 internal components...

"SandForce claims that the 2200 series has a 0% minimum over-provisioning improvement, which could open up additional storage space if the remaining capacity made it necessary to complete a write cycle."

The second half of that sentence is not a logical conclusion to the first. If something has 0% improvement, it means it has not improved at all. It does not facilitate a declaration it is the same technology although that is usually the case.

You're reading it wrong. SandForce SSDs previously had a 7% or more over-provisioning, and now they offer SSDs with 0% over-provisioning, which is an improvement.

I am not reading it wrong, it was structured comfusing for hte simple. 9% change means nothing changed.

As a matter of cat I have a MAX IOPS drive up for review as I type. And guess what.

One NAND chips worth of data density was set aside for OP and EC. 16 times 16GB = 256 GB not 240...


Only trying to help.

*edit also it means it has not decreased at all. (sorry that explains the logic in the PC community that nothing changed architecturally, it neither improved nor degraded).
