SanDisk Ultra Plus SSD Review (256GB)
by Anand Lal Shimpi on January 7, 2013 9:00 AM ESTAnandTech Storage Bench 2011 - Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011 - Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
Performance doesn't change too much with our lighter workload. The Ultra Plus ends up towards the lower end of the middle of the pack.

If you want to buy flash, buy flash.If you want to buy an iPod, buy an iPod.
But DON'T whine that an iPod (or iPhone, or iPad) costs "too much" because the flash in it is cheap.
It's not 2003. We all know Apple costs more (sometimes a little more, sometimes a lot more) than the competition. We also all know that Apple provides more (sometimes a little bit more, sometimes a lot more) than the competition. What we DON'T need is MORE fscking half-assed bitching about whether Apple does or does not "cost too much".
You want to do that, go read the comments on any damn tech site for any year from about 1976 onwards. Just don't waste our time bringing up the issue on modern threads, especially threads that have NOTHING to do with the cost of Apple's products.

It's not Apples products only, this applies to all tablets/smartphones. Google charges 50$/€ for an 8/16GB upgrade. Also, if you want to whine about people whining about Apple, please don't.mayankleoboy1 - Monday, January 7, 2013 - link

I really have to say I agree with this.This is not a choice between an Apple (or any other company's) device costing either "$n for a 16GB version and $n+200 for the 64GB" version or "$n for a 16GB version and $n+50 for the 64GB version". It's the choice between the former or a "$n+150 16GB version and a $n+200 64GB version". See? You're happy now, because the difference in price reflects the cost of the more expensive part. Except no one will every buy a 16GB version. Why would they? Only $50 more for 64GB. At the same time they would shut out a part of the market that just wants an iPhone, which they can get for $n, if you don't have the requirement of them only selling devices with largers capacity at the added cost for the part in question.
Pricing is so much more than just the cost of a chip. It's the way the company makes its money back on an investment. They wouldn't be able to sell the larger capacity phone at +$50 because that would raise the price of the low capacity phone and shut out a part of the market that wants that $n phone. And these people would say "Oh, see, Samsung phones only cost $n for a 16GB version, why does an iPhone have to cost $n+150?" It's an eternal neverending loop of some segment of your customer base that are not quite satisfied. The people who really like the 64GB version are dissatisfied with paying $200 more than the 16GB version, but the people who only need 16GB are glad to be able to get it for $200 less than the 64GB version. You change the rules and you just make a different customer segment unhappy, or just unwilling to buy your product.

It's nice to see Anand finally get some different brands to test, but unfortunately he probably missed the party on some key drives. There had been excellent prices on SanDisk's Extreme line of drives and it would have been nice to see how SanDisk's combination of high density / low die count toggle mode NAND stacked up against the likes of the Patriot Wildfire or OCZ Vertex 3 Max IOPS - Which was less extreme of a channel limitation as this marvell based drive. Also missing from his tests were drives from those such as Mushkin Enhanced who's Chronos Deluxe was frequently the cheapest togglemode+sandforce 2nd gen drive on newegg. Since all these other brands are missing from Anand's testing, it would be nice to get these charts to show a little bit more details in them about controller and NAND type rather than just linkspeed and occationally firmware version, so they don't have to be constantly looked up when making decisions.Kristian Vättö - Wednesday, January 9, 2013 - link
I finally got a Chronos Deluxe from Mushkin. I originally asked for it over 6 months ago (due to reders' request) but there were some issues with getting in contact with Mushkin.I think Anand also has a SanDisk Extreme.
To be honest, there aren't big differences between SandForce based SSDs. Corsair Force GS is an example of a SF-2281 drive with Toggle Mode NAND and FW 5.x.x, all similar SSDs I've tested (coming soon!) perform very similarly.

I just bought a Lenovo X201 Tablet. Can i use this drive with activated Windows 7 Bitlocker? Will Bitlocker slow down this drive and wear it down noticeable? Or does this drive have a hardware encrypten like the Crucial M500 from your review? If so how would i use it instaed of Bitlocker? I am sorry but I don't have any experience in encrypted drive.
