Hybrid SSD (New type of affordable hard disk)

[jerrycraft]

Hi,
I only heard of Hybrid SSD today. What is this technology?

 

[GBH187]

A hybrid ssd drive is just a normal hard drive with some flash added,

Vista is required to take advantage of it because the flash is used by readyboost

you can achieve the same performance gain by purchasing a 2gb or 4gb usb memory stick and using it with vistas ready boost system.


Its not a new type of affordable hard disk, its a fail technology that is already dead

I belive SSD was made for laptops because it uses less power and it's silent and doesen't get very hot.

*moved to computers and technology*

SSD or solid state drives are most certainly NOT dead. they are jsut not used for home use because they are not cheap at all. SSD are used in new ultra-high end servers that expect stupidly high levels of traffic because of 2 inherent advantages with SSD over disk drives. SSD runs without a moter, this means its lifespan is extremely long compared to HDDs, and theres less sound/noise from them. They also have a massive transfer rate if setup correctly, able to read/write to any sector without having to seek.

actually if you think of it SSD`s are not that expensive at all just take a usb drive like the corsair survivor its big enough to run windows xp on and a few programs,

 

[Nathan H]

there again, a usb flash drive is terribly slow compared to a full fledged SSD drive, though you would get the advantage of the low heat/no noise

 

[Zangetsu]

i wouldnt call 27.0 MB/s wright and 34.0 MB/s read slow

 

[Nathan H]

well considering the low-power laptop ssd drives can reach speeds of 250MB/sec read and 70MB/sec those speeds are pretty slow.

http://en.wikipedia.org/wiki/Solid-state_drive#Comparison_with_hard_disk_drives

theres a nice omparison list between HDD and SSD

This is going to be cool for vista users. If it was a pen drive, the access time to the usb port itself would be long and would not be advantageous for vista to use it as ready boast. But its integrated into the harddrive, it could be more advantageous as you all disscussed.

Vista i have seen booted in less than 30secs off of an SSD drive

 

[tnl2k7]

Vista will boot in under 10 seconds on a new install, but after you've installed Office and CS3, things start to get a biiiiiiiittttttt sloooooooooooooooooooooooooooow.

Solid state drives will be amazing when they reach the desktop, well worth the cash.

yeah cuz we are not going to pay 2K for a 128 GB SSD man for that kind of money you can make a decent gaming pc

I think you misunderstood the post. Hybrid drives are pretty much dead. There is no need to get a hybrid when you can get a fully-fledge SSD.

they are jsut not used for home use because they are not cheap at all.

wrong again. they are available for home use. I would not advise buying one, though unless it's an intel. they're not seen commonly in home computers because the random-write speed was 1/10 the speed of common hd's today - this is changing with Intel's multithread algorithm.

SSD runs without a moter, this means its lifespan is extremely long compared to HDDs

actually, depending on how much writing is being performed, it could be less. this is because of the oxification process used to store the electrons. the problem is nand flash degrades over time with each erase (again Intel has found a way to extend the life of their ssd drive)

SSDs no longer cost 2K, you can easily find a 64GB one for ~$200

-----------------------------------------------

To follow up with more information. Hybrid SSDs take's a regular disk and adds some flash memory to it for cache and fast reads, thereby minimizing the mechanical reads necessary on the disk (extremely good for commonly accessed system files).

SSDs removes the hard disks (as mentioned before). There are two types SLC and MLC, which stands for single level and multilevel cell, respectively. you want to hold off buying them until the random-write problem is fixed. all companies are using "sequenced" reads/writes to market their products, however you hardly ever do a sequenced write, which to-date is ghastly slow. whenever you write to your hard drive it's basically a random write. in most MLC SSDs today, sequenced writes may be 100MB/sec, but random writes are like 10MB/sec whereas a regular hard disk has something like 60-70 MB/sec for random writes. this MLC problem has produced hangs every 3 seconds.

SLCs generally don't have the random-write problem, but are more expensive and seen in servers, whereas MLCs are less expensive and can be found in desktops/laptops today.

Intel has developed a MLC that produces a random write of about 70MB/s. though, right now it's hover $500USD; however with a right speed equal to average hard drive today and read speeds that are like lightning, this makes them the SSD to get. just hold off for a bit and within the next 4 months prices should start falling. when intel's drops to $250, i'm getting 2 and setting up in Raid 0.

if you have any more questions just ask.

most people wouldnt find 64GB of storage enough i know i wont, and i said 128GB not 64 and if you dont believe me heres some proof


Memoright SSD GT 2.5" 128 GB, S-ATA € 2479,00

I believe that's easy to find something that costs the upper end, but that's not the average, and that's not for a home purchase; plus that price is not worth 2500, even for an SLC.

Sure you can find high priced ones, Newegg even has one for $3K USD, but that's not the home version, nor are they worth it. For 128GB, it'd be ~$400-$500 USD (the same as 2x64GB). And just so you know, it'd be better to buy 2x64GB and set them in Raid0 then to get 1x128GB; especially since there are no moving parts in Flash NAND - the likelihood of one failing is much more minimal.

Here is up-to-date info with a link:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2003240636 1421430849&name=128GB

As I said, the only one worth buying at the moment is the Intel (models like the X25-M), which is expensive. 80GB go for ~$500-600 USD, but the prices are soon to drop.

 

[Smith6612]

If solid state drives are faster than my 10,000RPM 1TB SATA II drives (no RAID config), then I guess I can certainly wait to get a new drive. However, I'm going to wait until they come out with 1TB drives or I'm never going to fit all of my data on them.

 

[vol7ron]

1TB makes no difference, the cache/block sizes associated with them can. However, SSDs have MUCH faster reads then 10,000RPM drives. I only use Raptors myself, so yes, this is a big deal.

The introduction of the SSD drives is about as significant an event as Conroe was to the processor. One day I hope we will have a RAM-less OS, with a HD the speed of RAM - this is getting pretty damn close.

Believe it or not this is already possible, there are (though not many) a few implementations of RAM based drives, blazingly fast and a fair amount of space, such a shame about the power dedication though. as soon as power is lost, the information is lost
