Greetings:

At $830.00 over the "80GB Hard Disk Drive, 5400rpm" default hard drive option, what advantages does a 64 GB hard drive have over any of the other choices?

If I go with Vista Business 64-bit, how much disk space will the operating system use?

If I went with a 7200rpm hard drive, how much faster is SSD?

For those who have already purchased an X300 or an X200 with SSD, how do you like the hard drive?

Other than being a no-moving parts hard drive, does SSD bring any other benefits to justify the increased cost?

Thank you.

The primary performance benefit is when accessing many small files (such as boot up) An SSD can be 5-10 times faster in that environment.

Very much enjoy it. Makes the X300 with it's slow CPU, extremely zippy. Launches applications faster than my Desktop (7200RPM, Quad 2.4). I do not dread rebooting my computer, even when it's on battery power.

Limited space is a big issue, especially with Vista keeping multiple versions of dll's. If the 128GB is SLC and has comparable performance, I suggest getting that.

I was one of the lucky ones that got the 64GB SSD as an option free when I placed an order during a price mistake debacle which Lenovo honored. Space would be the only issue of concern if you need more than 64GB on your laptop. Apparently Lenovo is using the best SSD drive available and it is priced the highest when compared to the rest. However read the entire article below which compares all the brands available in actual tests and the Samsung comes out on top by far..


I suggest reading this article below which was posted August 18th and will answer all of your questions..

http://www.tomshardware.com/reviews/fla ... 000-8.html

Samsung was one of the first manufacturers that contacted us once we wrote about the flash SSD Hoax. While well-designed flash-based solid state drives are both faster and more efficient than conventional hard drives, the majority of drives available are not (yet). Samsung, in fact, had good reason to submit its latest 64 GB flash SSD to us for review, as it is the only drive that truly combines high performance with amazing efficiency.

We first wrote about OCZ’s 64 GB SATAII SSD in our flash SSD Update instead of the Samsung drive, but mainly because the OCZ product, which is a Samsung white label, arrived at our test lab before the Samsung sample. At the same time, Samsung does not officially sell its Flash SSD at retail, preferring to provide the drives to system builders.

The performance results of the 2.5” 64 GB SSD SATA-2 are very much in line with what we measured for the OCZ 64 GB SATAII SSD, as both are based on the latest Samsung hardware. There is 90 MB/s read and write throughput as well as idle and peak power of 0.2 W and 0.8 W, respectively. I/O performance is acceptable, and application performance is at great levels as well. If you want to get the best flash SSD solution available, this is it.


Samsung’s 64 GB SSD SATA-2 drive provides high performance at superior energy efficiency and, as a result, receives the Best of Tom’s award, along with OCZ’s 64 GB SATAII SSD, which is also based on Samsung hardware.

Any idea if OCZ is coming out with a 128GB SLC as well?

Greetings:

Does the type of SSD drive used in the Thinkpad X200 have the same disadvantages as listed on http://en.wikipedia.org/wiki/Solid_state_drive (not including the price issue)?

Thank you.

Some of the Wikipedia comments are driven by the use of DRAM-based and Flash based SSDs in datacenters - not laptops.



Quote:
# Capacity – currently far lower than that of conventional hard drives (SSD capacity is predicted to increase rapidly, with experimental drives of up to 1 TB in tests.[13][14])


Well - you know the capacity - 64GB and 128GB - either it is enough or it is not.

Quote:
# Higher vulnerability to certain types of effects, including abrupt power loss (especially DRAM based SSDs), magnetic fields and electric/static charges, in comparison to normal HDDs (which store the data inside a Faraday cage).[dubious – discuss]


1) this is quite dubious. Both magnetic hard drives and flash based hard drives can lose data in a power loss. I'm not aware of any substantial difference. Of course, in a Thinkpad, you have battery back up for AC power loss.

2) most of these issues are unique to DRAM - not Flash.

Quote:
# Limited write cycles – flash-memory cells will often wear out after 10,000-100,000 write cycles[citation needed], while high endurance cells may have an endurance of 1–5 million write cycles (many log files, file allocation tables, and other commonly used parts of the file system exceed this over the lifetime of a computer.[15] Special file systems or firmware designs can mitigate this problem by spreading writes over the entire device (so-called wear levelling), rather than rewriting files in place.[16] Today's drives can last up to 20 years with average usage.[dubious – discuss] An example for the lifetime of SSD is explained in detail in this wiki.[dubious – discuss] SSDs based on DRAM, however, do not suffer from this problem.


All laptop flash drives have substantial wear leveling - but this is a risk, especially if you get a malicious or broken program that keeps writing to the drive. SSD endurance is less than magnetic disk - but it is not yet very clear if this is a real-world problem.

Quote:
# Slower write speeds – as erase blocks on flash-based SSDs generally are quite large, they are far slower than conventional disks for random writes and therefore vulnerable to write fragmentation,[17] and in some cases for sequential writes.[8] SSDs based on DRAM do not suffer from this problem.


Again - this is primarily a database issue. For the way most people use laptops - reading and writing files in large chunks - this is not an issue. Large hard drives use large sectors as well.


Quote:
# Lower storage density – hard disks can store more data per unit volume than DRAM or flash SSDs, except for very low capacity/small devices.


Perhaps this is hypothetically true - but practically the SSD one would use in a Thinkpad is smaller and lighter than the hard disk one would use in a Thinkpad.

Quote:
# Higher power consumption at idle or under low workloads laptop battery runtimes decrease when using an SSD over a 7200 RPM 2.5" laptop hard drive,[18] flash drives also take more power per gigabyte.


This has been observed. 2.5" hard drive power management is very mature. I think that the power management on some SSDs is simply poorly implemented and will get better over time. It is a minor effect.

Hard drive power is not very highly correlated with storage capacity.

Quote:
* RAM based SSD require more power than hard disks, both operating and when turned off.[19]



Not important to a Thinkpad.

I beg to differ on this... Even though the users may handle only large files, Windows itself have lots of small read & write operations (e.g. registry, logs)...

Sorry that I don't have figures on hand.

But then, most recent SSD seem to have improved controllers which speed-up random write operations considerably... Together with caching, and much much faster access time for flash, the performance impact may not be noticeable to end-users at all through.

Unsure about other OS...

consult this article for further reading on MLC SSD's and SLC SSD's: http://anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3403&p=7
basically non-Intel MLC SSD's have a performance (lag) issue, which SLC and Intel's new MLC drives don't.

Count me as another satisfied user of the Samsung 64GB SSD. In conjunction with a T8600 2.4GHz processor in the X200, it provides a great user experience. And the fan is never on.

Another "Samsung only" review not yet cited is:

Is possible to use any other brand than Samsung safely ? I'm asking it because of famous BIOS problems with T43/R52 and certain drives.

any brand SSD will work.   the BIOS limitations are only with the T43 and R52.

i have a samsung 64GB SLC SSD (same as in the X300) in my X61T and it works perfectly fine.   i tried crucial and mtron but the samsung is by far the fastest.

Well, no surprise that the Samsung blows the Crucial away but I am a bit surprised that you found it much better than the Mtron. The Samsung's performance must be really awesome.

the mtron i had was an engineering sample at 16GB with SLC chips.   it performed very close to the samsung but was slightly behind across the board by about 8%, possibly due to the controller chip.   new mtron drives may be better.

feel free to send me one and i'll test it back to back with my samsung. :D

Is having the SSD really an advantage that is worth the cost? I haven't had any problems with my other hard drives, I was going to opt for the SSD on my x200 but I couldn't justify the cost to the need. :?:

Unless you need much better performance, it isn't worth the cost. If you're looking for better battery life, you might consider the X200s with the lower powered CPU and LED backlit display both of which add to battery life much more than an SSD hard drive.
