The pursuit for the ultimate in speed is boundless, and ADATA leads the way in early adaptation of the latest SATA 6Gb/s transmission interface, implemented in the S501 V2 Solid State Drive (SSD). It incorporates select quality Micron chips, and high-speed transmission technology with the ONFI NAND Flash. Breaking records in actual environment tests, the S501 V2 achieves per second read speed of up to 355MB, and write speeds of up to 215MB per second write. This is almost twice the speed of a traditional SATA SSD, and many times faster than traditional hard drives.

The ADATA S501 V2 SSD leads the field in performance, so you can now enjoy the surging-speed thrill of the next generation standard.

SATA 6Gb/s Transforms the Definition of ""High-Speed"" In accordance with Serial ATA Revision 3.0 specification, based on the research and development of SATA 6Gb/s transmission interface, data transfer rates up to 6Gigabytes per second are, compared to previous generation SATA II specifications, twice as fast. Using the same cables and connectors, the new interface is backward compatible with older SATA 3Gb/s and SATA 1.5Gb/s interfaces. Overtaking not only traditional disk media, but also the SSD technology of the last few years, the ADATA S501 V2 represents a new generation in ultra-high performance specifications.
Superb Hardware and Extraordinary Features Combine to Create a New Generation of SSD The ADATA S501 V2 solid-state disk, in addition to its high-speed, is impact resistant, has low power consumption, provides noise and heat-free operation, and embodies all the benefits of previous generations of SSDs. The use of high quality and stability Micron chips ensures speed in transmission performance while enhancing data security. The introduction of the High-speed transmission technology standard: ONFI NAND, combined with a 128 MB DDR III memory cache, allows for improved data access, and higher read and write speeds. The use of active erasable compensation (Dynamic Wear Leveling) applications, not only mitigates the search time for read operations, but also reduces the number of erases, thereby increasing the lifespan of the drive.
Advanced Technology, Long-Lasting Transmission Efficiency In addition to superior hardware design, the solid state drive is a powerful tool which requires outstanding technology to achieve its full performance and speed capabilities through an extended lifespan. ADATA has brought years of experience into play, in order to fully grasp key technologies. The result is the carefully designed and engineered S501 V2 SSD. For example: the firmware, the application of techniques to enhance and extend the solid-state disk performance includes support for Windows 7, TRIM command, which handles garbage collection (GC) overhead without defragmentation. While writing data, the S501 V2 implements an intelligent algorithm, which thoroughly solves the progressive decline of transfer speeds that usually occurs with long-term disk use.
Rugged Inside, Dazzling Exterior The aluminum shell with silver etching gives an overall appearance of elegance. The product packaging includes a 3.5-inch conversion kit, allowing the drive to be used on both laptop and desktop computers.

MP 8/28/2012 10:07:18 PM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/54 Month update Pros: ADATA's tech support is wonderful. After updating my bios (Gigabyte MB) again after first getting this drive it improved the performance even better. Stats from AS SSD Random Seq read: 251MB Random Seq write: 196MB 4K Read: 4822 IOPS 4K Write: 10139 IOPS 4K-64Thrd Read: 39155 IOPS 4K-64Thrd Write: 36009 IOPS Overall score: 502 I get anywhere from 480 - 560 on the overall score. I don't know why it's so random but it is. It's still extremely fast when loading any data (games, browsers, MS Office, you name it) Cons: The original price I paid in May was 305$. It was inexpensive at the time, but wow what a difference in price in SSDs after only 4 months. Other Thoughts: Anyone who is reading this and think it's worth while. Take it from me. If you plan on buying this particular drive now, 4 months later, then don't spend more than 50 or 60 cents per GB. If I had a choice to buy another 256GB drive, I would probably buy an updated ADATA that has faster RAM inside. Please understand I am only referring to money with my statement, not the performance of the drive in which I am very satisfied with. I recommend this to all at the right price. Cheers!

j03 7/6/2012 8:42:55 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 4/5Noticeable Performance Improvement Pros: I have nothing bad to say about this SSD yet. I'm using it on a late 2007 unibody MacBook via SATA-II (3Gb/s) running OS 10.6. I have to say that it's a more noticeable performance improvement than a RAM upgrade. I've upgraded my RAM from 1GB to 8GB, which allows you to do more stuff at one time, but for across-the-board speediness, the SSD does the trick. Cons: Speed didn't blow my socks off, but it's good nonetheless. Other Thoughts: BIG THANKS TO DIRT BOY I also upgraded the firmware successfully to 007. http://www.crucial.com/support/firmware.aspx - then select "Crucial RealSSD C300 2.5-inch SSD". This SSD is a rebadge of that one as seen in System Profiler - "Model: C300-MTFDDAC256MAG". 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
MP 5/31/2012 8:39:25 AM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5Very awesome Pros: Still working excellent. Fast. My boot times have not changed after having Windows 7 x64 on it for 6 months now. This is my OS, swap file and game drive. I use Microsoft's built-in defrag on the drive and have had the same fast performance all this time. Cons: Price. Now the price of the drives have dropped dramatically. So if this ever comes back in stock, I hope it is MUCH less expensive. Other Thoughts: Worth it. Slower IOPS than other drives out there, but I can't tell (compared to a friend's Vertex3).

chaseu2 2/10/2012 7:14:30 PM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5Fast. Increased battery life. Pros: Boots faster. Battery life doubled! Cheaper than other SSDs. Cons: None after 3 months. Other Thoughts: I put the old HDD into an external enclosure. Then used WD Acronis to clone to SSD. Had no problems. My Asus P8700 laptop seems to boot/run faster, but the mind blower is that the battery life went from 2 hrs to 4+ hours. The price was good for me, and I found 256gb (from 320gb Hdd) was plenty for my needs. 2 out of 2 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
Boris Dinaburg 1/24/2012 1:13:22 PM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5no problems so far Pros: It's been 2 months+ and it is still working. Cons: none Other Thoughts: I didn't run any kind of tests to see if the theoretical speed lives up to the actual speed. The system starts up very fast though. 2 out of 2 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
Daniel 1/21/2012 4:06:10 PM Tech Level: 4/5 Ownership: 2/5 Verified Owner	Rating: 1/5Not Recommended Pros: Good price. Cons: I would not waste my time with this drive. I have cloned MANY mechanical drives to be replaced with SSDs and NEVER had an SSD drive fail at all. I have never had difficulty cloning an SSD, ever. This drive was difficult to clone. It took 3 attempts with Acronis software. It failed within 1 day of normal use. NewEgg replaced it with a brand new one and I could not get the second one to clone successfully after two passes. The computer, a brand new VAIO, would not boot...I just purchased 5 VAIOs over the past weeks for my kids and myself. I cloned & placed SSDs in each computer except for one with which I have had difficulty particularly with this drive. I am a BEE, classic, from Brooklyn Polytechnic, NY, although I work in medicine. I am no dummy and as I said, I have cloned MANY mechanical drives and replaced them with SSDs. This was the ONLY time I had trouble...I suggest using a more well known brand name. Other Thoughts: At first, NewEgg would not allow me to return it, but they agreed in the end and I will send it back on Monday. I thank NewEgg for acting in an honorable way!!! NewEgg, that is why I continue as a loyal customer, even if there is an occaisional glitch in the works...Thank you for continuing to uphold an honorable work ethic...

Dirtboy 1/20/2012 6:05:36 AM Tech Level: 5/5 Ownership: 3/5 Verified Owner	Rating: 5/5UPDATE THE FIRMWARE Pros: A great update for those coming from a mechanical hard drive to an SSD for the first time. Price was great considering the other drives at the same size. Rebadged Crucial C300. Everything screams! Cons: Firmware updates claim you need a SATA 3Gb port, of which I do not. Might not be required, but I took it to work to update it to be safe. Shipped with firmware 0006, which studdered. Firmware updates wipe the drive. Other Thoughts: The drive shipped with F/W 0006, which has a studdering problem. The drive would hesitate for 1 - 2 secs about every minute. This was evident especially when copying files. Didn't perform any better than a mechanical HD. I found out through reviews here that it was a rebadged Crucial C300 (even says so in my BIOS drive detection). If you get this drive, search google for "crucial SSD firmware" and get the 0007 firmware for the C300 and follow the directions there before you install anything. http://www.crucial.com/support/firmware.aspx Also, if you have large files in your Downloads, Desktop, Documents, Music, and Pictures folder, you may want to move your User's directory off the SSD. Great instructions at lifehacker. http://tinyurl.com/yfpkbuj 1 out of 2 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
DHGS 1/17/2012 7:10:22 AM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5ADATA S501 V2 256GB Pros: This is my third Adata ssd. I've had two 128's and this 256. All of 'em are screaming fast and have had no issues to speak of. Connected to a sata II notebook, i still get a WEI score of 7.6. Cons: Wouldn't fit into a new Lenovo Ideapad u400. the usb 3.0 port was blocking a corner that a mechanical hd wouldn't have filled. Not really a con, as all ssd's look pretty much the same. more of a design flaw. Other Thoughts: for RAM and SSD's, ADATA is great. never had any problems. 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
HBB 1/11/2012 7:04:53 PM Tech Level: 5/5 Ownership: 2/5 Verified Owner	Rating: 5/5More than satisfactory. Pros: The disk read and write benchmarks shown for this drive are completely accurate. Using the Intel AHCPI drivers and Roadkil's benchmark I peaked at 346MB/s read, 307 MB/s write with access times down around .16 MS. Boot times inside of Windows are down to about 30 seconds. 9 seconds from cold to end of bios, a further ten seconds to boot to login, and the final ten seconds is just waiting conservatively for windows to no longer have the blue scroll wheel at startup. Makes no noise, no heat, and allowed me to install Windows 7, update it, copy over and download probably 120 gigs of files and have everything to my liking in about 3 hours from start to finish--it's like I never switched save the speed boost. As for those who would consider not buying this because it has slightly lower read/write times than some other drives--you would be hard pressed to notice the difference between them regardless, go for it. Cons: Newegg shipped this inside of it's box, within a box. There was no packaging around it whatsoever--generally unacceptable to do for a product 1/50th the volume of the box it's in. However, these things are rated for pretty high shocks. Other Thoughts: I'll go back and make another review if anything ever does go wrong with this. 1 out of 1 people found this review helpful.

N/A 1/6/2012 7:52:23 AM Tech Level: 5/5 Ownership: 2/5 Verified Owner	Rating: 5/5Beginning is good Pros: Plug in play. That's all it took for my Gigabyte MB to recognize the ssd. (OS: Win7 x64 Pro) 238MB after NTFS format. :) The driver being used is ahcix64, I know this is different from down below but it is working. Cons: None. Other Thoughts: My AS SSD results are different than "3waits" below, but the end result scores are close to the same. I know my results are weird below, but that is what showed up. Anyway, it's fast and I am happy. My results are as follows: Sequential: ------------------------------ Read: 266 MB/s Write: 200 MB/s ------------------------------ 4K: ------------------------------ Read: 29 MB/s Write: 48 MB/s ------------------------------ 4K-64Threads: ------------------------------ Read: 85 MB/s Write: 72 MB/s ------------------------------ Access Times: ------------------------------ Read: 0.176 ms Write: 0.806 ms 1 out of 1 people found this review helpful.
