l********l 发帖数: 9452 | 1 SandForce固态硬盘主控制器非常流行,但是在TRIM方面远比其它方案复杂。一般主控
都是直接向NAND闪存写入数据,接到TIRM指令就简单地清除无效数据、恢复性能,但是
SandForce使用了一个实时数据压缩、去重引擎(动辄550MB/s的读写速度就是这么来的)
,TRIM的时候必须检查数据是否被占用,否则可能会把系统关键文件给清理掉。
一系列测试证明,SandForce主控在TRIM的时候碰到不可压缩数据(比如一部高清电影)
就会栽跟头,从来都不能恢复初始性能。Intel SSD 520系列使用独有的固件进行了优
化,依然未能根除这一问题,因此根源可能出现在SandForce主控的硬件设计层面上,
不可能通过固件解决。
更要命的是,SandForce TRIM在可压缩数据(比如大量文本文件)上也出问题了。
SandForce 3.x系列固件没什么问题,但是新的5.0.0/1/2版本中(固态硬盘厂商自己的
版本号会不一样),TRIM之后读取性能也恢复不上来。幸运的是,SandForce已经发现问
题并在测试新版5.0.3,一定程度上算是解决了,不过也付出了代价。 |

w*******y 发帖数: 60932 | 2 Micro Center just announced immediate availability of their second
generation Solid State Drive (SSD) featuring the SandForce SF-1200 Processor
from SandForce. The introductory price of $99.99 is fairly aggressive as
other brands using this controller are much higher than this. The OCZ Vertex
2 60GB is currently $139.99 and the Corsair Force 60GB SSD is $129.99 for
example. This makes the Micro Center drive about 23% less, but you might
have to pay taxes if a store is in your state.

http://www.newegg.com/Product/Product.aspx?Item=N82E16820233125
has dropped to $164.99 after $40 rebate, with $2.99 UPS shipping. It was
previously $189.99 AR "for a limited time", which I guess is true given that
it dropped $25 this evening. The rebate is good until 11/30.
This is the lowest I've seen a 2.5 Sandforce drive and matches the Black
Friday price for the much slower Kingston SSD.

d****n 发帖数: 12461 | 16 我反复看了网上的评测,觉得目前还是sandforce主控的ssd最好
intel x25-m的持续写速度比较慢,只有100M/s,只有sandforce的一半。只有内容是压
缩过的文件,例如mp3, zip这种情况,sandforce的表现会比较差,但即使这样,持续
写还是和x25-m持平。

t*********u 发帖数: 26311 | 31 SandForce的SF-2281刚刚遭遇了一次严重的打击,因为Intel检测到其宣称的AES-256位
加密实际上根本达不到,这是主控架构的设计问题,固件更新解决不了,所以Intel愿意
为用户全额退货。AES-256不达标理论上对用户的加密性能并没有实质影响,对个人用户
来说加密SSD的情况更少见,更谈不上影响了。
即便对安全没有实质影响,但是这仍然是一个质量问题,以致于SSD厂商不得不出来给个
说法。
最早发现问题的是Intel,他们给出的解决方式是:7月1日之前购买520系列SSD的用户可
在今年10月1日之前提出全额退款申请。
根据之前我们贴出的Intel SSD保修原则,英特尔是对零售渠道的OEM渠道提供5年全球联
保,因此用户可以直接拨打800电话要求保修,已经有网友操作过的过程是(仅供参考)
:
联系了 Intel的 800 售后,感受当上帝感觉的售后服务,说明购买的520 SSD要求召回
情况。英特尔会要求用户提供联系方式等信息,以及SSD的全部信息,包括SN、PN序列号
。
