Summary: Bought this simply because it was $35 (a year and a half ago from Staples.) Only just got around to actually doing something with it last week, only to find it is nonfunctional. It is not recognized in the included drive case, nor by the bios if I install it.
Summary: Again I am not bashing Kingston as they've taken care of my previous dead drive and gave me this one in its stead but wow, I cannot recommend this drive with its current WRITE performance.
Pros: This drive was sent to me as a replacement for a discontinued 64GB drive whose cells went out on it way too early. Stated Read speeds on this drive is what you get. Snappy performance in that regard, loads everything very fast for a low end SSD. Let me say, I am thoroughly impressed with the read...
Cons: HUGE Con. Write performance with this drive is awful. 18-35MB/sec sequential on a fresh install of Windows 7 64-bit? Though you may think you will not write often to this drive after tweaking settings to increase the life of the drive, don't forget there are numerous Windows update, driver update...
Summary: Kingston says they are "aware" of the problem and to "periodically check their website for a firmware upgrade" they are "working on". Uses a JMicron controller instead of Sanforce. Good luck.
Pros: Good Price, good read speeds, reliable at this point.
Cons: Horrible write performance on Crystal Diskmark benchmark. No tweaks (disabling pagefile, superfetch, system restore, etc) really make any difference. Shockingly poor performance for such a reputable company.
Summary: I have two V+100 96GB and recently got two SSDNow V200 128GB. The V+100 has toshiba controller and the performance was right on par with the specs, but the V200, with JMicron controller, is a totally different story. It is supposedly newer, with SATA 3 support, etc.
Pros: Faster than HDD Cheaper than competition 6Gpbs
Cons: Significant performance problem Slower than the older 3Gbps V+100 series Kingston tech support site got worse (see other thoughts)
Summary: Don't buy the V200 until Kingston has a chance to address the slow read problem.
Pros: It functions.
Cons: No improvement over my 7200 rpm platter. Reads fast, writes slow. The V200 series seems to have a problem. My V100 is great, this V200 blows. There's no firmware update available. I'll be selling this on an unnamed auction site and getting something else.
Summary: It was noticeably sluggish installing windows and programs. That's where I first noticed problems. The boot was fine since that's almost completely reads. I didn't order this drive from Newegg. I returned it and went for another budget drive from Newegg.
Pros: Decent read speeds. I was getting 240-250 MB/s reads using CrystalDiskMark3 on a nForce 405 S/B (SataII).
Cons: Absolutely horrendous write speeds! It seems to be a known issue with the V200 Series (Google sdnow v200 slow write). I was getting 15-30 MB/s writes at the same time as I benched the reads.
Summary: I bought the 256GB version of this drive to replace the 250GB HDD in my mid-2010 MacBook Pro running Mountain Lion. I contacted Kingston who told me it had reasonable not aggressive Garbage Collection and would be suitable for my Mac OS (where TRIM officially can't be enable for non-Apple SSDs).
