Just a few SSD questions.

only the OCZ Solid, apex and g.skill titan, still use jmicron controller, that are OCUK sell and do not have many left i guess will not be restocking these poor ssds

if your moveing from an norm hard disk to SSD, for the cost and speed to get, the Corsair S128 (samsung 32mb cache so no stutter) is Far faster then any hdd (ignore data rate)

if a single SSD is better than RAID for latency then why are people buying 2 for RAID?

if just to save £5-10 or whatever it is seems a bit silly

It's not for latency (if anything that will be a smidgeon higher in raid) it's for data throughput. The SSD's scale very well with increasing numbers giving incredible read/write throughput when raided.

so you lose some and you gain some, except the gain is bigger than the loss.

So this makes no difference at all to most things except file transfers right? loading games/apps is just as fast?

In my experience having SSD's raided does have an effect on load times of everything and responsiveness of the OS and hence overall system performance. It is of course of greater benefit when dealing with large files eg: video editing, however it does still have an effect on smaller files although the benefit to you the user may be less apparent against the overall increase by going SSD in the first place. TBH and imo whether you go raid or not with SSD's will depend on 2 things:

1 - Can you afford as large a capacity SSD as you need (or want) straight off? - or if you are unsure about the benefits (yes there are still people sitting on the fence about this one) - should you buy a smaller cheaper one now and then add another if you decide they are for you?

2 - What kind of user are you? Do you deal in massive amounts of data on a regular basis - or do you like to be at the bleeding edge of developments, squeezing every last drop of performance out of your rig?


Admittedly the reasons in No 2 above are less compelling than the financial ones, but still valid nonetheless as without people prepared to be early adopters of new tech and experiment with their rigs these forums would be a pretty lonely place!

I bought my SSD's when the 60Gb ones were out of stock and price-wise 2 x 30Gb's made sense - within a week I decided I needed more capacity as I wanted to get ALL my Apps/Games/whatever on them because they are damn fast and made my rig fly - so I bought number 3 and I haven't looked back since. If you can afford 120Gb Vertex or 128Gb "other non-jmicron" SSD then go for it and you'll be sorted! If not, buy what you can afford and add to it later - cause I promise you'll want to - and then you'll have the added benefit of extra RAIDed goodness!:D

of course there is the big risk of if a drive fails then you can kiss goodbye to both of them, are SSD's in RAID prone to fail as much as regular HDD's?
Click to expand...

I've never had either a regular HDD or an SSD in a RAID array fail - a bit too early yet to tell for SSD's anyway (hence why manufacturers are hedging their bets and typically going with a 2yr warranty on SSD's). But seeing as atm they are only really being used for OS/Apps drives then keeping a regular image on a mechanical HDD means that failure shouldn't a headache and shouldn't cost you any data loss. Apart from the short-term loss of a drive for RMA that is...

Performance drops quite a bit for the apps but everything else seems to stay the same.. bit disappointing, anybody else experienced the amount of slowdown once their SSD is quite full?
Click to expand...

No I haven't but then I suspect that here is another area where a RAID array comes into it's own as the added speed continues to assist things when a single drive starts to slow. I'm sure others will argue reasons against this, but I can only speak from my own experiences...

I would like to know if RAID does make a difference here, so if anybody else can possibly do some tests or something i think many would appreciate it.
 
it only affects Write speed, the speed that SSD runs at any way should not bother your selfs to much with it as it does not affect overall system speed at all only if your Writeing Lots of files at the same time (talking more then 100 files)
 
Wait.. you need 2 RAID controllers just to get the best speeds of 2 drives?, that's like what 100 quid worth on top of 2 SSD's what a rip off :(

anyway, i hope they can sort out that slowdown when the drive gets full

So, if write performance degrades over time or as the drive gets full and trimming is required, can we assume that the next generation of SSDs will comply with Microsoft's stated requirement ...

If “Trim” algorithm is applied, the “Trim” implementation must comply with ATA8-ACS2 proposal e07154r6 (Data Set Management Commands Proposal for ATA8-ACS2) section 5.3 and section 6.2. The completion time of Trim command should be less or equal to 20ms

For Windows 7 users anyway this must mean choose your SSD carefully (Windows certified).

As for now, can anyone tell me if Trim is working natively in any Windows 7 + SSD combo? Ta.
